The building is up for sale. Take 5 minutes to help us chart a course

The Planning Working Group has begun its efforts to address the upcoming building sale, and our first task is applying some scope to the project. This is the type of undertaking that could take years to get our hands around, but we don’t really have years. Even if we see out the end of our current lease (big if), getting ourselves in shape for a building purchase or even a move will take time.

So let us know what you think we should should be thinking about. What should be the top questions we are trying to answer? Yes, the building sale is the priority, but there are a lot of questions wrapped up in the building sale. For example:

  • What does PS1 want to be ten years from now?
  • How big should it be?
  • Should its mission evolve?
  • Should PS1 offer additional services, like studio rental?
  • What is the potential market?
  • What financing sources are available to PS1?
  • What do we have to do make ourselves “finance-able”?

This is very much a brainstorming exercise. Take five minutes to head over to this form and share your thoughts.

Member management changeover: this affects you

Update: new simpler instructions here.

We are transitioning off of ps1auth, our current member management system, to a new commercial system that offers more capabilities. Transitioning as in, this is happening now, many members have already made the switchover. Here is the tl;dr:

  1. Switching over is easy — takes about 3 minutes
  2. You do not have to switch over
  3. but you will soon lose access to certain equipment if you don’t

Now here’s the just-the-right-length; please-read version…

Switching over is easy

You can do it right this very minute. You should do it right this very minute!

  1. Go to (note the change in address from the old member site)
  2. Click “Join us
  3. Choose the “Existing Member Migration – Free” membership level Nope. See updated instructions here.
  4. Fill out the super-fun forms on the next two pages:
    • Use the same email address you currently use for PS1
    • “AD Username” is the username you will use for internal systems such as the wiki and computers in the space. You can re-use your current username. No spaces or special characters, please.
  5. Submit your details. You might think you are now done, but you are not done! You will receive an invoice via email sometime after you register.
    • We have to transfer your membership details over by hand, so this can take a few days.
    • The invoice is for the month after your Paypal payments end. Do not worry: you are NOT double-paying for the current month.
  6. Once the email invoice arrives, pay it by supplying a credit card. This will establish a new set of recurring payments.
  7. Cancel your Paypal recurring payments. (If for some reason you can’t access Paypal, let us know, and we will cancel for you.)

To reiterate: the new series of payment are timed so that they pick up exactly where your old Paypal payments leave off. You will not double-pay for any period. That’s it: a short sign-up form, and then pay the invoice. You are done. Crack a refreshing beverage and toast yourself for a job well done.

You do not have to switch over

You can ignore our pleading until the end of time and your Paypal payments will  continue to work.* Your membership will renew month after month. People will be born, people will die, the Earth will turn on its axis, for every season, etc. Life will go on.

But read on for a very major caveat.

If you don’t switch over, you will lose some access

Here’s the thing: in one month we will switch the internal computer system at PS1 over to the new membership system, at which point people on the old membership system will lose access to computers in the space. If you don’t ever use the internal computer system at PS1, you won’t notice. But if, say, you use the ShopBot or the Boss or any other tool at PS1 that requires logging into a work station, you most certainly will notice.

The changeover is not that far away. Switch now and your future self will thank you.

As an aside: if you are storing files on any computers in the space, a) keep in mind that there is never any guarantee those files will stick around and b) they absolutely will get wiped out during the member management system changeover, so now is a good time to back those files up.

Finally: we can help

If any of this is difficult you for any reason, let us know and we can make the transition happen for you. Just email for assistance.

* Probably not until the end of time, to be honest. Sometime, somehow, PS1 will update its pricing structure and Paypal will definitively die. But you would have to deal with that eventuality anyway.

All systems go: marathon paves the way for member management changeover

As you know, we are in the process of ripping the guts out of our member management system and replacing it with a commercial system called Wild Apricot. This is going to affect you, and hopefully eventually delight you, but these transitions are always a little complicated.

A brave band gathered recently for a Systems Group Marathon to lay the groundwork for this transition. PS:1 uses software called Active Directory (AD) to manage logins across our disparate systems. AD is what allows you to log into the wiki, the ShopBot, the website, etc., and soon our new learning management system with a single user name and password.

The marathon volunteers upgraded AD and got it working with Wild Apricot. This means that in the future, you will have “only” two passwords to manage: one for your payments to PS:1 and one for everything else. You shouldn’t need to touch payments very often, so this isn’t as hard as it sounds. Also, the new AD allows for self-service password reset, so no more desperate emails required if you get locked out.

Excitingly, Canvas is now up and running. Canvas, our new learning management system, will soon be the foundation for the authorization process at PS:1. We hope with Canvas to make authorizations both more convenient and more consistent.

With these changes and others (new Ansible playbook, new nginx, Let’s Encrypt SSL certs, etc.), we’re now getting very close to the Wild Apricot changeover. Emails will start going out soon to small groups of users. When the process is working smoothly, the entire org will change over.

A huge thanks to Abel, Wayne, Mariano, and our CTO Sky. If you’re tired of sitting on the sidelines and being overshadowed by heroes like these, bring your IT skills to the next systems group marathon. Do it for the accolades. Do it for PS:1. Do it for the pizza.

If you’re interested, Sky is always available on Slack in the #systemsgroup channel. She can also be reached at Finally, Sky has a frequently updated and public Trello board for all IT systems stuff that you can check out here if you want to know what needs to get done and what is being worked on.

Upcoming factory tour: Horween Leather

Update: the first tour is happening on June 12 at 11am. The tour is limited to 8 people and already has a waiting list, but Nick Horween has offered to conduct additional tours, so please feel free to add your name to the list.

Based on the enthusiastic response to the idea of factory tours, I have reached out to a number of local businesses. It looks like the first tour is going to be with Horween Leather.

Many of you have probably seen their building at the intersection of Elston and Ashland. Horween was founded in 1905, and continues to blend handmade craftsmanship with modern techniques:

Horween Leather offers an unparalleled blend of quality, consistency, responsiveness, and innovation. Through the years, we have cultivated our experience to offer dynamic lines of leathers. Our products include traditional, old world tannages and techniques, carefully updated with modern applications. Today, our leathers are still made by hand, the same way as generations ago.

Horween’s product lines range from sports leathers (footballs and baseball gloves) to high-end footwear and other applications.

If you are interested in touring Horween, please register here.

Some things to note:

  • We don’t have a time of day, day of week, or date for the tour yet. Of course we will try to arrange a time that works best for the greatest number of people, but no guarantees are possible.
  • The number of people who can attend is limited, and participants will be chosen by random lottery.
  • Reminder: if there are other places you would like to tour — and especially if you have any connections — please get in touch!

Wanted: help planning PS:1’s future location and, well, future

One of the tricky things in a volunteer-run organization is planning for the long-term. Positions turn over frequently, and it can be a challenge to develop institutional memory or focus on issues that play out over years.

Are you interested in helping to meet that challenge? PS:1’s building is up for sale. Although we have up to eight years left on our lease, most paths forward require action much sooner than that. We need to get our hands around this problem, and we especially need the help of volunteers who are invested in PS:1’s future and excited about making sure PS:1’s second decade is even better than its first.

At the same time, we have an opportunity to prototype a process for doing long-range planning of the kind that, so far, we mostly haven’t had much experience with.

To these ends, we are convening a Planning Working Group. Read more on the concept here.

Better yet, let us know if you are potentially interested in participating. Send an email to and write a sentence or two on the following:

  1. Why you are interested in joining the Planning Working Group.
  2. How much time you think you can realistically commit.
  3. Any relevant skills or knowledge you bring (none required, but if you have any, we’d love to hear about it).

Factory tours! Who’s interested?

On my list of “things to make happen at PS:1” is arranging factory tours to give members an up-close look at how things are made at industrial scale. The maker movement is about putting the tools of production in the hands of individuals, but that doesn’t mean we can’t appreciate or draw inspiration from the pros. Chicagoland has a rich industrial past and present. And a lot of this stuff is just plain cool.

I was reminded of this idea when I took a recent tour of a factory in South Chicago (more on that below). So consider this a call for interest and also a call for ideas. Does anyone know of any businesses, or even types of businesses, they would like to see the inside of? I’m happy to make cold calls, but of course if you have any contacts, all the better. Email me at

And here’s a quick photo essay on my recent tour. I’m not going to identify the company, or even the industry, but suffice to say it’s an old-school family business that has been manufacturing products in America for almost 100 years.

Although the factory mainly relies on CNC machines, vacuum formers, and water jets these days, it also keeps around a 120-year-old sewing machine for certain specialized jobs:

The nail-sized needle can punch through almost anything, and the machine ain’t broke, so…

There are a few other pieces of antique equipment still in use, like this cutter. It’s a little hard to see in the photo, but there are some nice hand-painted designs on the blade (click for a close-up):

This cutter is a little less antique, but no less pretty:

Foam is sold in massive blocks called “buns” because of the way they rise like loaves of bread when formed. Apparently you don’t want to be around to smell this process.

Buns are cut to size on massive vertical and horizontal bandsaws, in a process known as skiving. Skiving is a precision operation that results in thin, even slices:

The roller that feeds the foam into the blade can be replaced by “convoluter” dies, which come in a number of different patterns. Ever wonder how egg crate foam is made? This is how:

The dies squeeze the foam as it passes over the blade, creating the familiar dimpled effect:

Once cut to size, foam can be cut into more specific shapes using a 350-ton press. Notice the razor-edged patterns set into the wooden board. I thought I misheard when the press was described to me. Wouldn’t 350 pounds be about enough for cutting squishy foam? Nope, a clean cut requires a lot of force.

Replacing the member management system: help wanted

Big news: in the coming weeks PS:1 will move to a new member management system as part of ongoing efforts to revitalize some of our digital systems and infrastructure.

Details below, but here are some of the key points:

  • This will affect everyone, as people will have to move over to a new (better) payment system. Detailed instructions coming soon.
  • The new system will bring a number of advantages, including a more automated onboarding process; access to our new learning management system; an RFID-based  entry system to the building (no more PIN codes); better data security; and a system that is better able to handle future member growth.

We are switching to a new commercial system called Wild Apricot to manage members. At the same we are switching over to a payment processor called Stripe, which is very similar to Paypal except for the part about sucking the life out of anyone who touches it.

On to the details, including ways that you can help (please!).

What are we doing?

We are implementing a completely new Active Directory (AD) infrastructure to support the Windows systems in the space, which effectively requires rebuilding many of the critical systems that power space resources. AD will offer a robust and reliable infrastructure, while retaining the ability to use open source software where applicable for space operations. AD will be the primary source of authentication for almost all services. This includes access to space computers, RFID, the Canvas learning management system, and any future software systems.

How can you help?

We’re looking for members to help build up documentation and assist in overall maintenance of these systems. We’ll also need help with switching computers over to the new system and transferring member data and authorization, which is a manual process.

There are no prerequisites for volunteering to help other than an enthusiasm for computers. We are also looking for fresh ideas and helpful software beyond the list below, so if you have any ideas, please do reach out!

In addition, experience with the following systems would be helpful:

  • Active Directory / Windows Administration
  • Azure Administration
  • ESXi / vCenter
  • WildApricot / Member management systems
  • Database applications
  • Open Source Software (not limited to)
  • Ansible (& other IT automation infrastructure)
  • MediaWiki
  • WordPress
  • OpenVPN
  • RFID systems

Whether or not you have experience in any of the above, if you are interested in learning more about our systems, feel free to attend systems group meetings. These will be regularly scheduled and posted to the Google Calendar moving forward. These will mostly be weekend sessions devoting a couple of hours to building new infrastructure, brainstorming, and occasioally stabilizing old infrastructure.

We also need help with documentation. Assisting with documentation is an excellent way to become intimately familiar with our systems, and to ensure PS:1’s digital continuity.


The upgrade and maintenance process is ongoing (with no end in sight…sad face). We are first going to enable the new system for all new and incoming members. Then we will transfer current memberships to the new system. More details soon.

Speaking of VR, there’s a party in this cat’s mouth

The “Make Video Games” group at PS:1 came into existence about 12 months ago with a credo of “half art, half code.” Each session features a unique workshop, with a priority on demos.

Typically newcomer demos are featured first, followed by a code review of something simple, yet spectacular, in Unity 3D.

Workshops also focus on the creative aspects of game-making, including narrative design and game mechanics. Projects have ranged from pencil-and-paper board games to a storyline for a game that hacked a telephone automation system.

The focus for 2018 will be on hands-on workshops in creation of immersive content to be ported to multiple VR and AR (and XR) platforms, including HTC Vive, Oculus, Windows MR, Galaxy Gear and whatever the group can get its hands on.

Over time, the group has attracted the participation of talented professional game makers and video artists. For example, PS:1 member Mark Creasy 3D scanned his head and the PS:1 kitchen to pop out this psychedelic gem:

Here’s a bit of behind-the-scenes on how Mark scanned the room for the video:

For more of this goodness, of course, show up at the next session of “Make Video Games.”

CNC round-up: new areas hosts (!) and structure

As the old saying goes, it takes a village to replace Ash Jasani, and accordingly the responsibilities in the CNC area have now been distributed across three people. Thank you to three new area hosts for graciously offering their time:

  • Andrew Sowa is host for the 3D printers
  • Zander Bueno is host for the laser cutters (and vinyl cutter)
  • Hank Peterson is host for machining — the ShopBot, Shapeoko, Tormach, and other devices for making chips

This change reflects a longstanding issue: the number of members and pieces of equipment has ballooned over the years, but the number of people filling operational roles has remained nearly constant. These means an ever-increasing workload for the area hosts, which in turn requires them to focus their energy on only the most pressing issues.

Dividing up responsibilities allows the hosts to focus their energy more narrowly and productively. As a case in point, Andrew Sowa has kicked off his tenure by donating a homemade post-cure station to PS:1.

This fancy Easy-Bake oven will make it easier to use our two Form 1 machines. Says Andrew:

UV resin does not come out of the printer fully cured, so further processing is required.  UV light (405nm) and heat are applied to make sure the print is converted to a solid. This process can drastically change the material properties, and it is important that conditions be reasonably well controlled. My little toaster should offer good enough control of heat and light to dial in the best post-cure for different materials.

Also, it looks cool:
