Laboratory B

Lab B Moves into New Digs at 12-22 North Street!

Location of the new Lab B entrance on the exterior of the buildingAfter a heroic move-out effort by Lab members and volunteers, and a month of being a "virtual Lab" operating out of a storage locker, Loomio group, and pop-up event spaces (thanks, Bytes.co!) we're pleased to announce that Laboratory B once again has a space!

After considering several possibilities, our membership voted to move into a room on the second floor of 12-22 North Street in the Old North End. In addition to our new HQ space, where we'll be holding public hours, meetings, co-working sessions and small workshops, the lease also gives us access to a number of shared spaces we can use after business hours, including a dedicated electronics lab, a sizeable class/event space on the first floor, and basement storage.

Many things about the Lab will stay the same, but a sampling some of the changes the move offers that our members are excited about include:

  • Handicapped Accessibility for Many Events: In the Soda Plant, all of our space was up a set of steep stairs, limiting accessibility of workshops and other events for folks with mobility challenges. While the Lab's dedicated room is similarly only stair-accessible, our ability to reserve the large downstairs space means that many of our public-facing workshops and events, such as mobile security night and LAN parties, will take place in accessible spaces.
  • Direct Access to Our Space In Off Hours: In the Soda Plant, the outside door was usually locked after 5pm, so public event attendees needed to ring a doorbell and be guided through a labyrinth to access the space. So, we're every excited that our new space has a door opening directly to the outside.

    Some members in the new Lab B (after hauling up the first load of chairs and a table)

  • Environmental Impact: In the Soda Plant (and the Hood Plant before it), we were occupying the decaying remains of industrial infrastructure, and it definitely showed in the winter time with heat loss through single-pane windows, etc. By contrast, 12-22 North Street is an optimized energy-efficiency machine: it was built by a worker co-op in the 1980s with a passive solar design, has significant installed solar electric capability (including wiring for DC lighting), and is run by a landlord who works on IoT sustainability and environmental impact monitoring. The fact that we have a monthly kWh cap in our lease has sparked our thinking on how to sip rather than chug energy (no more using out-of-date servers and crypto miners as de facto space heaters in the winter). Whether this transition means our aesthetic center-of-gravity will shift from cyberpunk to solarpunk remains to be seen...
  • Space that is more fully "ours": At the soda plant, we were subletting from Brandthropology, who were incredibly accommodating partners, but pretty much all of our space was at least somewhat shared, in they needed to walk through our main room to get to the shared Couch Room and kitchen. We now fully control our core space, while also having access to additional shared spaces and resources in the building.

We'll be spending the next few weeks moving in and setting up, and are planning to host a "Lab Warming Party" for our initial Thursday public hours on February 21 from 7-9pm. For more details, check the Facebook event, and, as always, keep an eye on our calendar for upcoming Lab B happenings!

Workshop – Strandbeest Walking Robots – 24th Feb 2019

A workshop with Martin Raynsford

With kind permission from the trustees and generous assistance from Ian Dickinson, I would love to come to Nottingham and put on a workshop making my Strandbeest walking robots as seen in this video.

The kit contains everything you need to build a wind powered strandbeest walker, with additional components to motorise the design and control it from your mobile device. The kit generally takes about 2 hours to assemble but if you’re already competent at soldering that will easily be less. The boards come pre programmed but I’m happy to stay after and help people set up their arduino environment if they want to play with the software.

The date is provisionally set for the 24th of February at 10am, the price will be £25. Booking is not essential but I need positive confirmation from a few attendees to ensure it actually happens. Contact MSRaynsford@gmail.com to book a space.

More information about the kit can be found here.

The kit itself includes a wemos D1 which uses the ESP8266 so it’s a great introduction to that wifi module. It’s been a long time since I’ve been to the space so I look forward to seeing some of you again in February.

Introduction to Arduino Workshop on Saturday 2nd March 2019

James Fowkes and Ian Dickinson are planning to re-run the popular Introduction to Arduino Workshop on Sat 2nd March 2019 11:00 am to 4:00 pm at Nottingham Hackspace.

This is a great way to get started with the Arduino and requires no previous knowledge of electronics or software. You will start by getting a LED to flash (the beginning of all great electronics projects), and progress to adding switch inputs, controlling a motor and reading analogue sensors.

Cost for the workshop is £25 with all money (less Eventbrite fees) going to the hackspace.

Arduino starter kits will be provided for use at the workshop. We will also have starter kits (£35) and Arduino Unos (£18) available for sale.

To book, please visit: http://hsnottsarduino19.eventbrite.co.uk

This workshop is limited to 15 places, but as this event often sells out, early booking is advised.

Feedback from a recent attendee: “Attended recent workshop, it really is very professionally run! The trainers inspirational and empathetic to slower learners, supporting material is well organised relevant to the workshop, reasonably paced. The logistics flawless all students had what we needed on a desk when the class started and at each section as we advanced through the projects, Congrats to everyone involved.”

Hackerspace Envy — A Visit to Revspace in The Hague

I just had my second visit to Revelation Space, a hackerspace in Den Haag, Netherlands, and this time — I took pictures. This place is seriously tidy and organized, and is full of slick automations. There’s so much inspiration I had to write it all down.

Revspace flipdot display

Label All the Things!

At some point Revspace hit upon the same realization that we did: it’s better to just bite the bullet and buy a full standardized set of sturdy shelving and compatible bins than to hack together a storage solution with whatever free and cheap bins you find floating around. It’s no fun trying to get parts out of drawer that won’t open because the plastic tower it’s in is so laden down with stuff that the drawer can’t open anymore.

Revspace shelving

And, omg, they label EVERYTHING. This is awesome, though, because I think a lot of newbie energy is wasted when people want to help clean up but don’t yet know where things go.

Revspace shelving

The policy at Revspace is that when you’re done you clean up 110% of your space. And seeing completely bare tables when I first arrived early in the day convinces me that they actually do it. And they have arranged things to facilitate it — of course with the great shelving and labeling, but also with cleaning supplies out front and easy to get to. They even have a washing machine for washing shop towels to cut down on paper towel use. (You can see the bins for clean and dirty rags on the shelf.)

Revspace soldering kit

I’m really taking inspiration from their soldering station storage solution, and I’m ready to go replace the falling-apart cardboard boxes that are holding our soldering irons at Resistor. They’ve gone the extra step and include everything you need — including desoldering tools, a roll of solder, helping hands, and even a silicone baking mat from Ikea to solder on so you don’t burn the table. And of course, each box is thoroughly labeled.

Revspace soldering kit

I should also mention, that box is sitting on their surface mount soldering station, which was spotless, of course (except for my coffee cup, oops).

Revspace trash bins

Do people not use you space’s wiki? Do they also not know how to deal with common problems around the space? Here’s a way to kill two birds with one stone: post QR codes that take you right to relevant page in the wiki. The ones in the photo tell you what to do when the bins are full.

Chore Management

Speaking of taking out the trash, here is their solution for dealing with the random chores that need to get done in any space that no one wants to do, or that people feel they don’t get recognition when they do do them so why bother?

Revspace chore bounty sheet

They have a simple sign-up sheet on the fridge. Folks can sign up ahead of time to do a chore, and when it’s done it gets signed-off on and they get paid with a deposit into their RevBank account (more on that in a bit). Here sweeping up or vaccuuming gets you 10 euros, taking out the trash 5 euros, and mopping 25 euros.

Hackerspace Banking

Revspace revbank terminal

Banking in the Netherlands does correspond to Dutch stereotypes — which is a great thing. You can always split a check in a restaurant and they have some slick mobile apps to keep track of who paid for what during trips and outings that also provide ways for everyone to be reimbursed easily. So it’s no surprise to learn that a Dutch hackerspace has developed their own accounting and funds transfer system to help members pay and get paid. And that would be RevBank.

The public-facing part of RevBank is a terminal sitting right next to the fridge and the snacks, with a barcode scanner attached so you can scan your item, then scan or type your name, and you’re done. The source is here. It’s written in .. uhm, perl. Have fun with that.

I gave it a whirl while I was there, and was able to top up my account with a bank transfer (this statement makes sense in Europe — you can also do cash instead). And then I used it to pay for all my snacks that day. Worked great, quite efficient.

Revspace revbank terminal

Everything is on MQTT and I Love It

Revspace space switch and buttons

Around the space they have several things under automation, including the sound system, door locks, laser log, a flipdot display (!), and they also have several sensors. I made a dashboard for Resistor with the dashboard modules in Node Red, but I like the look of their’s, which is in Grafana, so I’m looking forward to playing with that.

Revspace dashboard in grafana

MQTT is a simple publish/subscribe protocol that makes it easy to get a scattered herd of wifi-enabled devices all talking to each other. It’s a delightfully simple protocol, I kind of love it, but it really deserves it’s own post, so check back for a future post on how we integrate it into our own automations at Resistor.

Revspace badge reader

They’ve automated their door locks and have iButton key fobs. Of course there’s also code. They look really cool, but I don’t think we’ll be switching away from our Brooklyn-standard vertical deadbolt anytime soon.

Family Meals

And finally, they have a huge kitchen and they actually cook evening meals in it. There’s a “nomz” button that sounds an alert and updates the flipdot display in the main room when dinner is ready. And you know you’re still in a hackerspace because there’s a wall of maté in there.

Revspace wall of mate

So, if you get a chance, and you find yourself in the Hague, do go check out Revelation Space. They’re very welcoming, and they definitely have it together. Did I mention they label everything?

Revspace labels everything

Pumping Station: One

Growth and churn analysis of PS1’s membership

I used historical payment records to analyze member growth and member churn, the rates at which people join and leave the organization. The data set also allows analysis of how these rates differ by gender.

Growth: fairly slow and getting slower

New members joined PS1 at a remarkably consistent rate on an absolute basis between 2015 and 2018. On average, 25 new members join per month: 20 men and 5 women. On a percentage basis, this represents a declining growth rate, despite the fact that PS1 dues continue to fall in real terms, and the space doubled in size and added new equipment during this period.

25 new members might seem like significant growth, but members leave at a similar rate. Net growth averages 1.0% per month. Net growth of female members was actually negative every month between July 2017 through March 2018.

Churn: new members don’t stick around long, especially if they are female

Churn, the rate at which people leave PS1, has varied over time. For male members, the churn rate has dropped steadily from 9.6% per month to 5.0% per month. For female members, churn rate has been as high as 12.3% per month, and was 8.5% per month in early 2018.

Cohort analysis provides a behavioral lens on the data. In their first six months of membership, female members churn at an average rate of 11.5% per month, compared to an average rate of 7.5% for male members. 45.9% of women leave PS1 within six months. 33.7% of men leave PS1 within six months. Overall, 55.6% of new members leave within the first year.

A club of older members

The “age” of a member refers to the duration of their membership. For example, a “two-year-old” member joined two years ago. In growing organizations, average member age is often flat or even declining over time, as new members join and older members leave. At PS1, member age has climbed steadily, a reflection of moderate growth and churn that is concentrated in new members.

What it means

There are at least two ways to view the high churn rate among new members. The first is that this reflects a natural sorting process as people discover whether there is a good fit between their interests and what PS1 offers. Perhaps PS1 is like a gym membership for many: an aspirational purchase that they don’t end up using.

Alternatively, perhaps PS1 is failing its new members. Anecdotally, many have noted the difficulty of navigating PS1’s authorization processes, rules, and cultural practices. Some might find the hurdles too high to clear.

These explanations aren’t mutually exclusive, or exhaustive. Almost certainly they are both at least partly true. The gender disparity in growth and churn, however, suggests that the hurdles are higher for some groups than others.

Less ambiguous are the implications of a high churn rate for PS1’s finances. The space’s sole source of funding is member dues. A high churn rate makes growth difficult; adds additional administrative overhead and demand for authorizations; and raises the risk that the low net growth rate could tip negative with small changes in underlying trends.

See a more detailed analysis and discussion the methodology here.

Art area: new for 2019!

Hello, everyone!

Here is an overview of what is incoming for the Art Area in 2019. I expect to have everything in place hopefully before the end of January to early February. Thank you to everyone that responded to the annual usage and needs survey.

Make t-shirts on demand

Color printing! This has been a while in the making. Many t-shirt printing systems I have looked into had no actual third party reviews, usually are dedicated units of questionable functionality, lack any information on ink permanence and are super over-priced. The ‘direct to garment’ units look super shady. After looking at option after option for years, I am going with an easy solution. We have a mid-range Konica Minolta CMYK color laser printer coming. We will be able to affordably refill its toner thanks to member Latrice Dixon; she tipped me off to inkowl.com and their great deals. Transfer films for printing color will be available to use with a heat press. If you want to make MAD amount of t-shirts, Neenah Paper Techni heat press transfer paper films for laser printers films are as low as $31 for 50 films on Amazon. This brand has two types for light or dark color t-shirts. Members interested in zines and self publishing will be happy to know this unit accepts a pretty wide range of paper weights and finishes. Printing patterns and instructions will be easier. Manufacturers do not claim full-bleed (edge to edge) page printing in the specs that often as OS, software and users are all a factor: so I am not sure if we can manage full-bleed printing on this unit until we have time to check it out. Konica Minolta has an overall good reputation with the graphic design community for out-performing HP or Lexmark similarly priced printers.

Dye sublimation has been upgraded

The prior gravity feed system gets air bubbles and the flow is poor. Members got some use but it under-performed. This gravity feed system has been replaced with a refillable cartridge system for the Artisan 1430 printer. Dye sublimation works for transfer sheets to put images on synthetic fabrics, glass and metal projects. Make your auntie that cat pillow for 2019. =^-^=

More paintbrushes

Please wash paintbrushes you use with soap and water and heckin put them back. If you are using an oil-based media, please use a proper solvent and then wash brushes with soap and water. More brush soap has been ordered. Also, it is bad to leave brushes sitting bristles down in liquid; they warp. (I have a set of watercolor brushes that I have been consistently using for 28 years.) Brushes are not a single-use item. Do your part. Be kind to the brushes. A clean brush is a happy brush!

Swivel headed heat press

This is a smaller 9×12″ unit but may be easier and safer for members to use as you can keep the heat element away from your hands. If you think a clamshell heat press is kind of scary, this new one is kinder and gentler.

Noise suppression

Heavy weight fitness center rubber mats are going under the Singer 20U industrial machine and the work bench that has the heat presses. Hopefully this will muffle any whomping and hammering sounds that carry through the floor to CNC below. Thanks to Ray Doeksen for advising me that this was happening.

Upgraded lighting

Two new LED daylight tabletop task laps are coming and the overhead daylight light bulb tubes are getting replaced. LED lighting for the printmaking bench will replace the old halogen lamp.

Pro model button maker

You LOVE LOVE LOVE button making! You literally wore out the small button press; the plastic slider warped. This budget unit has been replaced with an all-steel pro model. We have a 1.25″ and 2.25″ button making presses and new pro circle cutters for each. IF you want to make insane amounts of buttons, I can refer you to sources to buy parts; Amazon also has vendors for button making parts.

New leather working tools

Leather working tools are replaced. Please return any leather crafting hand tools when you are done using them and do not take them home. I have needed to replace every single item this year. Share the tools, please!

Power strips and extensions cords

New and not frayed. Please do not remove these from the Art Area. If people need to plug in a piece of equipment at a particular table, I want them to easily be able to grab an extension cord or reach a power strip. Do not take them down to the other shops as they will get dirty.

Sewing machines

A new electronic Brother CE8100 with automated button holes is here, replacing the prior Husqvarna machine. The Brother has many more stitch styles. There is also a pro bobbin winder for the Singer 20U that I just have to install. Also, on the white book shelf is a small tin box with these new plastic fabric clips to use instead of pokey pins. These are helpful for delicate fabrics you do not want to put holes in or thick fabrics like fleece that are not easily pinned. Less stabbing, more sewing!

Let’s be tidy!

Lemon disinfectant wipes, Simple Green and window cleaner are in stock; see the drawer under the black and white printer. There are dusting cloths. I also discovered and ordered a mega box of paper towels to help with spills and stuff that gets on tables. Please do not leave your projects laying around and do not stash your project materials in nooks around the space.

New light boxes for photography

The old photography light tents tore and the frames broke, the tripod lamps wore out or broke when they tipped over. The new units are hard bodied boxes that collapse easily, so you do not have to be an origami master to put them away. The new light boxes fold out, snap into place, and have LED lighting built into the photo box itself. A 12″ and 20″ light box with sweeps are incoming. Heavy weight colored artist drawing papers make better background sweeps if you want a particular color. Document your projects for blogs or portfolios, get product images for online sales, or make weird 3D clay animations. The potential is huge.

Adobe Creative Cloud

Adobe Creative Cloud is on both PCs for you to use; both the Artastic PC and the one with the Wacon Cintiq HD22 pen tablet.

Soliciting class ideas

Partner with me for planning and the art area can fund needed materials. If there is money and enough interest, let’s get some classes running. I have ideas for zero cost / free classes for 2019 which will be easiest to run in the summer when school is out.

As always, touch base with me in open office hours or by email if there is anything I can help you with or if you feel there is a need that could be met. Please help by putting hand tools away in their labelled storage containers; which has been going very well so keep it up. If anything is broken or not working properly, please put a sign on that piece of equipment and email me right away.

All the best to everyone being creating and making stuff for 2019!

Lab B Seeks New Space for 2019 and Beyond

After several years in residence on the top floor of the Soda Plant on Pine Street, Laboratory B has officially left the building as of 1/1/2019. Many thanks to the members who put in lots of hours, leg, and back-work over the past month to prep to space for our move, and also great appreciation to the friends of the Lab who showed up on the 30th to help with the big move day!

Half-way into filling the storage locker...

The move has been a great opportunity to assess and discard a good deal of superfluous stuff, while our core materials are safely ensconced in a Champlain Housing Trust storage locker, ready to be deployed at our next space....

We’re already in talks with a few possible new sites for the Lab, but are being deliberate about the process so we can land on the best spot for our community’s needs. We’re in search of a space with a maximum all-inclusive cost of $700/month; it can have shared spaces, be a sublet arrangement, etc., but needs at least one room that Lab members will have exclusive access to. So, if you have a lead for the next venue for Burlington’s member-run and -governed hackerspace, please get in touch by shooting an email to info@laboratoryb.org!

In the meantime, Lab-sponsored events will be popping up in various locations around town, and we’ll be using the spare capacity derived from not having weekly public hours to do some internal work to position us for success in our 5th (!) location since the Lab was founded in 2009. If you want to keep in the loop, follow our shared calendar and Facebook page, where events and announcements will be posted, and we'll post to this blog when your new space is finalized.

Happy New Year, and we look forward to sharing the next iteration of Laboratory B with the Burlington community in the coming months!

Hack the Space Weekend: 8th-10th Feb 2019

[See further details on the wiki]

Message from the trustees

Dear Member,

Recently we have been discussing within the teams and membership that a number of large jobs have been on the list for a considerable amount of time. The Trustees along with the teams have decided that we have enough jobs now to run a “hack the space” weekend. The purpose of this would be shutting the space during this time where no members other than volunteers of this weekend will be permitted to use the space. This will cover both upstairs and downstairs, the following jobs are currently in the plan.

  • Replacement of studio floor

  • Redesigning the Large Project Storage Area

  • Reorganise comfy area including rewiring of speakers

  • Checklist of tools and PAT testing

  • Electrics within the workshop (replacing lights) etc

  • 2.5 jobs TBC

The Trustees request that all teams please keep thinking on what else needs completing and a wiki page will be set up so members can see the job list, place their names against the jobs and the times they can volunteer their time.

Our proposed shutdown will be on 18:00 on Friday 8th February till 18:00 Sunday 10th February.

As you are aware the Trustees are also taking a break for Christmas so I remind members that it make take some time to get any questions answered during this time. I will be taking point on this project and making sure that we have enough people to do the jobs along with materials ordering and liaising with Teams to make sure everyone can have a great day and take part.

If you have any questions you can email the trustees or myself directly. [addresses in Google Group post]

I look forward to posting more information in the near future.

Regards,

James Adams On behalf of the Trustees

Board election: who’s running, when it’s happening, what food will be served

We have a full slate of candidates for the PS1 board this year, as well as a consequential upcoming vote on the new bylaws. Here is a timeline of election events as well as a details on the current set of nominations and candidate platforms.

Events

Candidate Q&A
Tuesday, January 8, 8PM: Candidates are invited to attend the regularly scheduled member meeting and deliver a short presentation on why they are running and what they hope to accomplish as board members. The event will include a Q&A. We also broadcast the event live via Facebook.

Election day mixer
Tuesday, January 15, 6PM: come early on the official voting day for a catered mixer. In addition to food and drinks, we will be hosting an outside delegation from Korea who are interested in learning more about the U.S. maker community.

Vote
Tuesday, January 15, 8PM: the in-person vote will take place during the regularly scheduled member meeting. People will also be able to cast votes by proxy in advance.

Candidates

These are the candidates as of December 19. This post will be updated over time, and you can also check out the election wiki page for the latest information.

President
  • Andrew Camardella
Vice President
  • Alisha Ciardi. Candidate statement:

I am running for Vice President because I am passionate about making and it’s ability to empower people and create community. I’ve collaborated with the Board on multiple projects this year including leading the design and implementation of Tormach authorization (launching in January 2019), assisting with designing and collating data from the first-ever PS1 Membership survey, being a part of the Planning Working Group, and assisting with documentation for Wild Apricot Member Management migration.

My primary goals, if elected, would be: (1) to improve internal communications allowing for more seamless community engagement and a more graduated volunteer structure that reduces burnout and impromptu power consolidation. I think this would allow for more consistent maintenance and improvement of PS1 in a variety of ways including but not limited to cleanliness, courtesy, and enforcement of rules to improve fairness. (2) I want to focus on active listening that encourages input from more members,  helping to facilitate increased communal collaboration and ownership of PS1. I’ve already started working toward many of these goals as mentioned above and I would be even more effective if elected in an official capacity to support the operation of PS1. I hope to see you at the Pre-Election Q&A Event on January 8th!

  • Joe Mertz. Candidate statement:

The majority of the work I do at PS:1 is to benefit the space, and id be happy to continue that as Vice President. I believe Jennie and Andrew have set a wonderful example for the positions and I hope to follow in their footsteps. I have also strived, since I became comfortable in the space, to be an ambassador for the space to new members and potential members, and I believe that that is an important goal for board members to have as well.

Secretary
  • Alex Zhu
  • Andrew Sowa
Treasurer
  • Jennie Plasterer. Candidate statement:

Brian has done a wonderful job recording our accounting processes, and I would like to continue in his footsteps with that, as well as finding external entities to manage as much of our treasury processes as possible in the hopes of easing the tension and danger involved in future Board turnover.

Chief Technical Officer
  • Sky Nova. Candidate statement:

It’s been tough going but we’ve already made a lot of progress in fixing systems up and increasing reliability. I believe we’ve only had two major outages this year, and both of them did not have a particularly large or immediate impact. The Wild Apricot migration has been difficult, but we are nearly at the turning point and I believe we can finally and fully switch over before the end of the year. Keep an eye out for updates on this!

Director of Public Relations
  • Mark Creasy. Candidate statement:

I have a decade in advertising agencies and broadcast production as a designer, producer, technical & art director for national brands, winning awards and shaping brand voices… and while I have healed from that, I am positive I can amplify what we do across mediums.

Directors-at-Large
  • Molly Adamski. Candidate statement:

I use our space to create things both for myself and for my small business (Workshop-25), so I am there quite often. As Director-at-Large in 2019 I want to focus on improving cleanliness at PS1. I have a wide range of experience in committees and clubs; most recently I was the Membership Coordinator of my graduate school’s Professional Bridge Networking Program, and the Vice President and then President of my school’s STEM club before that. Like many of the members who answered our recent survey, I feel that the space is too dirty & disorganized and that this inhibits one of the primary missions of PS1: allowing people to create. I believe that by working together as a community to institute my “Culture of Cleanliness” initiative we will have a cleaner, better working PS1.

  • Alex Berkowitz. Candidate statement:

I would be honored to serve as Director-At-Large for the 2019 Board of Directors. This past year, I worked closely with several other members to develop the training & authorization process for the Tormach, and will continue serving as authorizer going forward. I am eager to contribute to maintaining and improving the amazing community and unique resources PS1 provides in whatever ways I can, but I feel my biggest contribution may come by way of education. In addition to working on the Tormach project, I have also served previously on the board of directors of an ACM SIGGRAPH chapter, including two years as president. As such, I have a lot of experience teaching technical content to students of all ages and skill levels. PS1 offers numerous learning opportunities to its members including authorizations, workshops, events, and social interactions with other makers. However, there are ways all of those things could be improved and, starting with this new year, I would like to focus on doing so. Thank you for your consideration.

  • Carl Karsten

I’ve been involved with PS1 from the beginning, not as a founder, but just around to help out now and then.   I have seen PS1 grow from a struggle to survive to the fairly stable organization we have today.

I have served on the board before, speaking up when I was concerned, and (believe it or not) keeping quiet once my concern had been heard. I did not always vote for the winning position, but that’s OK PS1 did OK anyway.

As a Director-at-Large my ambition is to simply support the rest of the board as we keep PS1 running smoothly for another year.

As a member, I will keep running Python Office Hours every other Wednesday. I want the new by-laws in place asap.  I want to get rid of the donation boxes scattered about, update the “Who to Call” page that is taped next to the front door, and I’ll take out the trash now and then.

Results from PS1’s first-ever member survey

In August, PS1 conducted its first-ever member survey to better find out who we are, how we use the space, and what improvements we would most like to see. 190 people responded. The results are available here.

Some highlights:

  • Although member satisfaction is generally high, by far the largest complaint members have about the space centers on issues of cleanliness, organization, and tool maintenance. Concerns like these are sometimes dismissed as unsolvable given PS1’s loose, volunteer-run structure. But the frustration members feel about their inability to get work done in the space cuts straight to PS1’s mission of enabling people to create, and survey respondents had lots of viable suggestions for improving cleanliness, tool uptime, and the layout of the space.
  • The main reasons that people join PS1 are, unsurprisingly, access to tools and to workspace. But the next most common reason is access to community, and many members seem to be hungering for more opportunities to meet, share projects, learn new skills, and interact face-to-face. PS1 should consider ways to foster collaboration.
  • PS1 is not very diverse. 82% of members are white and 82% are male. In fact, PS1 seems to be growing less diverse over time: the group of members who joined in the past year are more homogenous than previous cohorts, although it’s impossible to tell from the survey what might be driving this trend (or if it even is a trend). Nevertheless, the survey does show that members of PS1 who are not white males cite social and cultural issues as needing improvement at a much higher rate than white males.

The full report contains a detailed breakdown of all the survey data, complete with pretty charts and fancy tables. Please read and discuss.

AGM re-run: Thursday 24th January 2019 @ The Hackspace

Email to all Members from the Trustees

As you may be aware, we were unable to conduct the AGM in November as planned as unfortunately we had insufficient members represented either in person or by proxy to be quorate. Our constitution requires 20% of the membership to be represented at the AGM. As a result of this we need to re-run the meeting.

The date for the Nottingham Hackspace Annual General Meeting (AGM) re-run is Thursday, 24 January 2019. It will be held in the Hackspace Classroom (downstairs). Doors will open at 7.30pm and the meeting will begin promptly at 8:00pm.

If you’re a member of Nottingham Hackspace, you need to attend in person or allocate a proxy to represent you at the meeting. We have a number of special resolutions we need you to vote on.

Proxy Voting

If you can’t make the AGM in person, you can make a proxy vote, whereby another member will attend and submit vote(s) on your behalf. If you’d like to register as a proxy voter, or alternatively if you are able to attend and would like to volunteer as a proxy, please add your name to the wiki list at: https://wiki.nottinghack.org.uk/wiki/2019-01-24_AGM_Proxy_Votes

Quorum

For the AGM to happen we need 130 members represented. This is the required quorum as per our constitution. As per section 1.129 of our Articles of Association, if we do not have a total of 130 members (present and proxy voters) then we will not be able to conduct any business and will have to rearrange the AGM for another time.

Agenda

The agenda for the AGM will be as per the 23 November meeting and is available here: https://wiki.nottinghack.org.uk/wiki/2019-01-24_AGM_Agenda

 

Thank you for being a Hackspace member this past year, and we look forward to seeing you or your proxy at the meeting.

Kind regards,
Nottingham Hackspace Trustees

NERP: CircuitPython Workshop 12-17-18 with Kattni Rembor!

NERP (Not Exclusively Raspberry Pi) is PS1’s embedded programming interest group. At a special NERP on December 17, Kattni Rembor will be giving a workshop on Adafruit’s Circuit Playground Express board running CircuitPython. This is a paid event.

That’s right — the next NERP is not free and open to the public! There’s a first time for everything! Registration details here.

Kattni Rembor is an embedded software developer, technical writer, and community leader with Adafruit Industries. She joined Adafruit as a member of the CircuitPython team, and has written the definitive Getting Started guide, the library designed to make CircuitPython simple to use on Adafruit’s premier learning board, as well as many project guides and tutorials. She has helped build the amazing, supportive online community around CircuitPython and a wide variety of other open source topics.

Find Kattni on Twitter or Discord.

Workshop description

CircuitPython is Python that runs on microcontrollers. It is designed for learning and if you are new to programming or electronics, CircuitPython can help you get started with both. All you need to do is plug in a microcontroller board and start writing code.

Participants will be given a Circuit Playground Express microcontroller board to use. This beginner-friendly workshop will introduce CircuitPython and cover the basics. Then we will get into working with code. There will be a series of examples that use the various sensors, lights and switches built into the Circuit Playground Express board. We will start simply, and we will build on the concepts learned, combining them as we go to eventually build a light-up, capacitive touch tone piano.

Doors open at 6:30pm. NERP is usually free and open to the public, although this event is paid and requires registration.

For those who are interested, there will be the opportunity to stay after the break for further exploration.

Requirements

We will be using Mu as our code editor. Mu is an editor that has the serial REPL and a plotter built in, and makes getting started with CircuitPython particularly easy.

Participants must bring a laptop (ideally running Windows 10, Mac OSX, or a recent version of x86 Linux) and a compatible USB Micro cable (e.g., USB-C to USB Micro if you have a newer Mac). Be sure that your USB Micro cable includes data transfer capabilities, and is not charge-only as it will not work if it is charge only.

Board elections! Run for the board! Board elections!

PS1 will be holding annual board elections on January 15, 2019. Board elections affect everyone in the organization, whether you are a voting member or not, and you can participate in all sorts of ways: running for a seat, voting in the election, or simply asking candidates questions about the issues you care about.

If you are interested in shaping the future of the organization, please do consider running for a board seat. The only requirement is that you have to be a member in good standing for the six months leading up to the election. New members are absolutely eligible for the board and encouraged to run.

You might be used to thinking of board members as remote god-like beings who bestride the earth like a colossus. And that’s because we absolutely are. The point is that you too can be one of those god-like beings, doing all that bestriding.

If you are interested in learning more about what the board does, please attend a board meeting. We have board meetings on the first and third Tuesday of the month at 7pm, and they are always open to the public. Or reach out to a board member directly.

The board (presently) has eight positions:

  • President
  • Vice president
  • Treasurer
  • Chief Technology Officer
  • Public relations director
  • Secretary
  • 2 Directors at large

You can learn more about what each position entails, and who the present board members are, here.

Wondering how to get authorized on the Tormach? Here’s how

When PS1 got the Tormach 1100, our single biggest investment in a tool, we were determined to do it right. Not just the installation, but also creating an educational path that went far beyond a standard authorization.

PS1 has just launched its first two provisional authorization sessions. Students were selected who had already attained the prerequisite authorizations. To get authorized on the Tormach, you first need to get authorized on:

  1. Tier 1 Metals
  2. Bridgeport
  3. ShopBot

You should also be proficient in CAM before getting authorized on the Tormach.

Assuming you have all that stuff on lock, getting authorized on the Tormach is as easy as 1-2-3:

  1. Take an online course and pass the associated quiz
  2. Attend a Tormach live training (2-3 hours)
  3. Submit a personal project for CAM & G-code review

Events & Resources

In addition to the authorization path, there are lot of ways to get more familiar with the Tormach and its amazing powers.

Meet-ups

Fusion360 Meet-UpsAndrew Camardella hosts biweekly Fusion360 meet-ups to spruce up your CAD & CAM skills. All skill levels welcome. Check the events page.

Tormach user Meet-UpsStarting this winter, will be having public Tormach user group meetings to discuss tooling, projects, machine optimization and other related topics.

Online

Tormach wiki pageStay up to date with Tormach resources at PS1 on our wiki page.

Tormach Slack Group: Join our slack group #Tormach_User_Group at pumpingstationone.slack.org to talk with other PS1 Tormach users about all things Tormach.

Bringing VR/AR tools to PS1

VR Demos at PS1

I’m Mark, the new kitchen area host, and I’m trying to bring all the benefits of VR/AR/MR to disciplines across Pumping Station: One. Below’s an example of how I’m using it for food design.

You are welcome to come talk to me about incorporating experience-creation tools for food purposes during kitchen office hours Saturday 10am to 12pm, but I’m also interested in enabling you to use these for your own projects. Sundays from 12pm – 3pm we’ve been having “Let’s Make VR” upstairs in electronics. The current project is trying to capture our space in a demo that can be shared with the outside world using VR, helping members capture and display their projects in virtual spaces using photogrammetry and 3D scanning, and recording 360 training to be used in the app.

Screens from a new PS1 VR gallery.

If you’re an area host and you’d like some training recorded, reach out to me to schedule a time. If you want to use our tools to recreate and capture experiences, see how your furniture is going to look in your living room before making it- or send it to a friend and let them check it out with AR tools, come to one of the above events and let’s talk about it. More members are getting familiar with the tools & we’ll be posting tutorials to Canvas soon.

Member Project: Slide Hammer

Aka: The Shiv of Self Love (The Wanky Wanky Shiv)
Stats
Made by: Josh and Steve
Status: Finished
Tools used: 3-in-1 lathe, TIG Welder
Description
Well it started as an oil change and before we knew it we were removing the apron from the Colchester Triumph 2000 lathe, but more on that later. In order to remove the apron we needed to take the lead screw and feed shafts off. Disconnected at the thread cutting gear box side all that was holding them in was a bracket on the right of the machine. In turn this is secured by two screws and two dowels.
The screws were easy enough to remove, the dowels less so. They are an interference fit but have a thread in the centre to which it is intended to connect to and using a slide hammer pull them out. So the simple plan was to insert a bolt and pull them out, trouble was a M4 bolt was too small and a M5 had the wrong thread. Then it dawned on us, imperial. Trouble was at this point we had half disassembled the lathe and realised that we had neither an imperial bolt of the correct size, nor a slide hammer. Looks like we were going to have to MacGyver our way out of this one…

Welding the tap to the shaft

Sure enough after some trial and error we located a tap of the correct size and pitch (though we’ve forgotten to make a note of that size and we don’t have an imperial thread gauge). Now we had something to attach to the dowel we needed a slide hammer and this is where the threaded rod came into play. Manually cutting a shorter length of rod to use we took the rod to the 3-in-1 lathe and started with a centre drill before moving to a 5.5mm drill bit to 10mm depth at one end.

Drilling the bore of the side

This little recess was now the correct size for the tap to sit in. But we needed to secure it so Josh broke out the TIG Welder and welded the tap to the rod. This formed the shaft of our slide hammer, and a nut was added to the non-tap end to act as the hammer stop. All we needed now was a slide.

Using the slide hammer to remove the dowels

A quick raid of the metal stock found a small steel cylinder that had already been drilled through to around 6mm. However we needed a 12mm hole and this is where we hit another problem, the biggest drill bit we could locate was 10mm. Undeterred we embiggened the hole to 10mm on the 3-in-1 lathe. And then finally using a 12mm end mill the hole was taken to the correct diameter.

The removed dowel

Our slide hammer was now complete, so back to the Colchester it was. Tap end well inserted only a few hits were needed and the dowels were free. The bracket, shafts, and apron could then be removed

The slide hammer competed

Creation of the slide hammer was fairly straight forward and was made even easier with the two of us working together, Josh on the Welder, me on the 3-in-1 lathe. However, with a little more planning we might not have ended up needing to fabricate this tool. But it was a bit of fun to do and is a tool that will live with the Colchester in case we need to remove the shafts again which I hope we don’t.

This side hammer is awesome

Laboratory B

9/27, 7pm – FOIA Party at the Lab!

Ever wondered exactly what those black helicopters are up to? Thanks to a federal law called the Freedom of Information Act (FOIA), you can find out!

At the FOIA party, we'll get together, brainstorm ideas, teach the basics, and discuss techniques for getting the information you're after. Bring your most burning government questions (local, state, or federal), and we'll make sure everyone leaves with at least one request under their belt.

The "Intro to FOIA" presentation by Brian Waters will start at 7:15 and run approximately 30 minutes, including Q&A.

Following the presentation, there will be a workshop session in which attendees will file their first FOIA requests, so, if you are interested in doing so, bring along a laptop!

Member Project: Swingarm Bushing

Stats

  • Made By: Steve
  • Status: Finished
  • Tools used: 3-in-1 lathe, 16mm reamer, Arbour Press

Description

I have a Honda Grom and like any good motorcyclist I take pride in modifying my bike. This modification involves replacing the standard steel swingarm with a Tyga aluminium over braced item. This is a straight swap however I wasn’t happy with the new arm as it had like the OEM arm rubber bushing at the pivot instead of roller bearings that I would expect.

Bought replacement Swingarm

Bought replacement Swingarm

The problem here was that despite my best googlefu and the help of a local bearing suppliers I couldn’t locate a set of roller bearings at the correct size that being 12mm ID and 24mm OD by 42mm length. So having already removed the rubber bushing I decided the best solution here would be to turn some bronze bushing to size to remove the flex of the rubber bushes.

So I ordered some oilite bronze stock and headed to the 3-in-1 lathe. Checking my feeds and speeds I turned the rpms down on the lathe and set about turning the outside of the stock down to fit. With that set it was time to drill the internal diameter to 16mm to fit a pair of needle roller bearing internal sleeves.

Bronze stock on the 3-in-1 Lathe

And this is where I made a mistake. Drilling the centre out to 16mm resulted in the internal sleeve simply slipping through the hole. Turns out twist drills are not that accurate. So I started again, this time drilling to 15mm and then finishing off by hand with a 16 mm reamer. The sleeve now fitted perfectly.

Two attempts to drill

Next was to put the bush into the swing arm where by I found the next problem. While one hole was 24mm the other was around 23.5mm so was to big to fit. I solved this by putting the bush back into the lathe held by a live end in the tail stock and dead end in the chuck to enable me to hold the part while being able to work the length of the piece.

Retry on the diameter

Finally with both bushes the right diameter I used the Arbour press to insert them securly into the arm and then fitted the arm to the bike.

Bushes inserted into Swingarm

These were made in a few hours over the course of a couple of visits to the space. I could have completed this in one evening if I didn’t have to wait for my new reamer to arrive.

A Capacitive-Touch Janko Keyboard: What I Did at the 2017 Georgia Tech Moog Hackathon

Last weekend (February 10-12, 2017) I made a Janko-layout capacitive-touch keyboard for the Moog Werkstatt at the Georgia Tech Moog Hackathon. The day after (Monday the 13th), I made this short video of the keyboard being played:

"Capacitive Touch Janko Keyboard for Moog Werkstatt"



(Text from the video doobly doo)

This is a Janko-layout touch keyboard I made at the 2017 Moog Hackathon at Georgia Tech, February 10-12. I'm playing a few classic bass and melody lines from popular and classic tunes. I only have one octave (13 notes) connected so far.

The capacitive touch sensors use MPR121 capacitive-touch chips, on breakout boards from Adafruit (Moog Hackathon sponsor Sparkfun makes a similar board for the same chip). The example code from Adafruit was modified to read four boards (using the Adafruit library and making four sensor objects and initializing each to one of the four I2C addresses is remarkably easy for anyone with moderate familiarity with C++), and code was written to send a gate (key down) signal to the Werkstatt, and to write a binary representation of the pressed key (low note priority) to an Arduino port connected to a precision R-2R ladder to generate the voltage for the VCO exponential input.

The capacitive touch sensors can be used to make a touch keyboard with any configuration, not just the Janko. With these sensors it's remarkably easy to make a functioning electronic musical keyboard, as no mechanical switches or moving parts are needed. The feeling is at least as responsive as a "real" keyboard, as response to touch and release feels instant as far as I can tell. If anything, there's a "problem" in that if you accidentally, even slightly, touch a key it will sound, whereas with a mechanical keyboard you have to "accidentally" press a key down for it to sound.

A traditional seven-natural-and-five-sharp-keys layout would have been just as easy, but less "interesting." I chose the Janko layout after having read about it for many years (see Paul Vandervoot's piano video "Demonstration of 4-Row Janko Keyboard" - he describes the layout at 4:06). The Janko has, from left to right, six whole steps per octave, thus is one less key wide per octave than the traditional keyboard, so with the same key spacings the Janko octave is a shorter distance. Going up or down diagonally is a half step, so a chromatic scale of all 12 notes is a zig-zag pattern. A major scale is the first three notes in a line (whole steps), diagonally up or down to the next key (a half step), this and the next three keys across (whole steps), and then diagonally again (a half step) to get to the octave key. You can start on any key and the major scale is the same description. This is the remarkable property of the Janko layout, there are very few patterns to memorize for the different scales and chords.

(End text from the doobly doo)


I used an Arduino Mega 2560 (actually the Inland brand compatible board from Micro Center), because I thought I would use more I/O pins than on an Uno. This project can be done on an Uno, but the direct write to the Mega DDRC and PORTC registers (and perhaps other I/O pin assignments) may need to be changed for the Uno. If you don't know how to use the AVR port registers directly, you may be better off just using a Mega 2560 rather than trying to change the code for an Uno.

No direct work for this project was done at Freeside Atlanta (nor at Georgia Tech's Invention Studio - I cut these pieces of wood to size at home using a circular saw just before going to the hackathon, then hot-glued everything together at the hackathon), but I did some preliminary work done at Freeside. I had been wanting to make some sort of Janko keyboard for a while, and in recent months I've 3d-printed a couple of rounded-rectangle "keys" to help get the feel of what I wanted. (The short time of a one-weekend build kept me from using anything other than a rectangle shape on this project, and even then I only had one octave done by 5PM Sunday.) I decided on key spacing the same as "standard" piano keys, which are about about 165mm (6.5 inches) per octave. Since the Janko layout has six (whole-step) keys per octave instead of the traditional seven (major scale) keys, this octave is about 141.4mm or 5.57 inches wide. The distance from one row of keys to the next above it is 1.8 inches, and each row up is 0.53 inches (the approximate heigth of a sharp note on a standard keyboard) higher than the previous. These numbers are mostly just "good guesses" as to what the dimensions of such a keyboard should be for good ergonomics. If you make one of these, feel free to make whatever changes you like, even a traditional key layout or something totally different.

The keys are made of brass strips. I had a brass sheet, dimensioned 6 inches by 24 inches by 0.004 inches. I cut this into rectangles of 1.5 inches by 0.75 inches. I soldered wires to one side and glued the soldered side down to a plywood board with hot glue. Each vertical pair arranged (first-and-third row, or second-and-fourth row) were connected together and connected to a sensor input on the MPR121 breakout board.

For greater versatility, each key could be connected to a separate sensor input (doubling the number of sensor inputs required). This would allow the vertical pairs to be "wired together" in software for the Janko layout, or for each key to generate a different note. This would be ideal for generating microtonal scales such as 24 notes per octave.

The current code implements a monophonic keyboard for a single voice analog synthesizer. The keyboard priority is for the lowest note played, and retriggering is off (you have to lift off all keys and press a key again to get a new gate signal). Many enhancements can be done, such as highest or last note priority, retriggering, and sending polyphonic MIDI data, and adding adding modulation wheels on the left side for pitch bend, LFO modulation amount, and other possible performance parameters (I think there should be at least three such wheels, with the third one changing the filter cutoff frequency). These are, as always, left as an exercise for the student.

Blatant Blurb for Synthesizer Class

This Tuesday, February 21 2017, I'll be putting on a class at Freeside:
"Introduion to Electronic Musical Instruments."
I'll cover analog music synthesizers, and have this Janko keyboard instrument and others in the Synth Petting Zoo after the class. There is a $10 charge, this covers the time and cost of setting up and of using Freeside to put on this class. Sign up here:

33C3 : Works for me

Each year with winter comes the Chaos Computer Congress in Hamburg.

2016 edition : 27-30 dec. Survival guide for this 33rd edition :

” Works for me”

Like no other, the year 2016 pointed out how well „works for me“ works for us.
It does not. Mutual hate, envy, insensibility and exclusion have driven us apart.

Feeling isolated and threatened, we turn further against each other, take less care of each other and worry even more about ourselves. And yet, we are never alone: Excessive surveillance is now politically normalized, if not for all then at least for those who are different, intractable, foreign.

Let’s break this vicious circle.
Let’s get together and live our utopia.
Let’s strive for something that works for all of us.

And let’s fight those, who will not let us!

Welcome to the party! 🙂

 

Avec  chaque hiver vient le Chaos Computer Congress, cette année du 27 au 30 décembre.

Bien plus que les autres, l’année 2016 a montré combien « works for me » marche pour nous.

Ca ne marche pas : haine mutuelle, envie, insensibilité et exclusion nous ont déchiré. Les sensations d’Isolement et de menaces nous oppose, nous faisant prendre moins soin de chacun et nous préoccupant plus de nous meme.

Et nous ne sommes toujours pas seuls : la surveillance excessive de tous est maintenant politiquement normalisée, ou au moins des différents, etrangers ou rebelles.

Cassons ce cercle vicieux.

Rassemblons nous et vivons notre utopie.

Battons nous pour quelque chose qui fonctionne pour chacun de nous.

Et combattons celui qui ne nous laisse pas faire !

Freeside Atlanta

What to Do With a Stack of Picture Frames?

When You Have Too Much Free Stuff!

Our newest member Raul got his hands on a stack of about 40 picture frames that were being junked. On a general note Freeside tends to discourage large piles of objects randomly appearing as it tends to collect in corners. Raul got permission from our projects team with a time limit of a few weeks. In this case unnecessary, as the membership more or less attacked the pile of boxes and rapidly rendered them into things.

Unfortunately starting off all the frames looked something like this:

Not terribly useful. We don't even have any idea who these guys are. After a few passes through the planer, however, we get something like this:

A perfectly good picture frame useful for stuff. First idea was to push a couple of these through a the laser cutter. Concept good, aim.... Aim was a little off. Also we had just rebuilt the laser computer and electronics so there were a couple of kinks to work out in CamBam's post processor:

 

Instead of getting distracted by that rabbit hole of troubleshooting, though, Nathan, in a process pioneered at Freeside by Mr. Ferguson, took a few frames and burnt some Lichtenberg figures. The actual process is pretty straightforward. Soak some wood in saltwater, hook a microwave oven transformer to the wall up backward, and poke the scary ends into the wood. There's some insulation and other safety jazz that I'll leave to: Google.

The raw frames come out a little (a lot) sooty and salty and need cleaned up:

Sanding and staining, or painting, plus a layer of polyurethane gives these:



But Wait. there's More!

Before the rest of the membership got ahold of those picture frames, Raul had intended on making a stool. We actually had a broken branded stool lying around to use for parts. The next day he was working on putting the stool together. After some disassembly, sanding, nails and whatnot:

A wild stool appears!

Rebuilding The Kraken

"The Kraken" is one of Freeside's 3D printers, designed and built by a former member. It is the light blue printer sitting off to the side on most photos of our 3D printing zone - sadly, the machine has never printed quite right and it's been down for repairs more often than it's been usable. It's design had some major flaws, particularly in the frame that was fairly unstable. When it did print it would make great looking parts, but the bed leveling was fickle and imprecise. With the AO-100 and more recently the Mini, there wasn't a lot of reason for our members to use it.

So I decided to rectify that and rebuild it completely from the ground up into a RepRap "Wilson", a popular design reworked from the Prusa i3. I chose this particular build because there are a lot of information available and a great set of info and instructions on both the RepRap wiki page about it, and the github page for the parts. It's a well known RepRap and has been tried and true by a lot of people.


The other reason I chose it was because I could build the Wilson utilizing 100% of parts salvaged from the old Kraken. The goal for the rebuild was to recycle every nut and bolt and try to keep the total cost as close to zero as possible.

From start to finish, the rebuild took about 3 months working off and on a few hours a week. The initial tear down took a couple of hours at the end of November 2015, where everything was counted and bagged and boxed up. At that point I ordered some new ABS to print the frame parts, and a couple weeks printing things on both the Mini, and my personal 3D printers at home. In trying to keep with the look of the old machine, I printed in "Sky Blue" ABS. The final product is actually really nice to look at!




While I was in the process of building The Kraken, I decided to go ahead and build my own Wilson from parts from a failed RepRap build of my own last year. So in a lot of these photos you will see an identical looking black Wilson. For my own, I bought some "hidden" corner brackets to help with the structural rigidity of the machine, as well as some corner braces I had from my previous build attempt, and used the spares for The Kraken. I definitely recommend this for anyone building a Wilson as it greatly improves the strength of the frame.




Some time ago, The Kraken's original J-Head hotend was replaced with a Budaschnozzle 2.0, since that is what we already have installed on our LulzBot AO-100, and having the same hotends allows us to keep fewer type of replacement parts on hand. We bought a replacement PTFE tube to convert it from 1.75mm to 3mm filament to be consistent with our other 2 printers - again, so we don't have to keep two types of filament on hand - and the nozzle was cleaned of old filament. It was left soaking in acetone overnight, then scrubbed with a fine wire brush.




We bought a new aluminum Y carriage to replace the old acrylic one. The aluminum carriage is lighter and more sturdy than acrylic, which has a tendency to flex and torque, so the new design will be able to print at much higher speeds than before. We kept the same heated bed, but replaced the glass print surface with an aluminum plate covered in PEI. Aluminum is a good bed surface as it dissipates heat more evenly, but it also lets us install and use an inductive Z probe to auto bed tramming, a stand out feature of the Mini that I have since upgraded my own printers with.

 
The RAMPS board had to be modified as it was missing the + voltage for the endstops, which the inductive sensor needed. Once that was added, the board was installed and the wiring was quick. I used some left over cable management from my previous 3D printer builds as well as my personal Wilson to help keep all of the stray wires in check, which the old Kraken suffered from. I also replaced the old server PSU with a more common project PSU found in Freeside's obtanium.


The machine was upgraded to the latest version of Marlin and configured to use the auto bed tramming feature. There is still some fine tuning in the firmware to be done, but overall the printer is running great. I'm really looking forward to seeing projects from our members come off of the machine!

Build Out 12-5 Photo Recap

Freeside just finished our Build Out for the end of 2015 and we got a lot of work done. Let's see what all we accomplished.



Brian repaired the vacuum former and planned out a new heating element design.




Mike came all the way from Florida to frame the Member Storage door and put in a new lock to prepare for some new security features.




Nathan and crew totally reorganized and cleared out some old obtanium. The new shelves are much cleaner looking.




Michelle hacked the LulzBot AO-100 to increase the maximum height, and started printing parts for a new RepRap for the space.




Kelly and Scott cleared out the attic of all of the old random stuff to make way for all new random stuff.


Rowan, Brandon, and a few others helped to sort glassware for the bio and chemistry room.



 Paul, Jonathan, and Earl examined strange fruit.


We demolished in Member Storage for some more new metal shelves.




We put away tools that had found their way from the tool room.



We browsed memes.


We found some time to goof off.




Thanks to everyone who came out and helped make Freeside awesome. See you next time!
