Automation Station: One (DIY CNC night) July 20th 7pm

The desktop manufacturing revolution has been gaining traction at PS:One over the past few months.

We had the recent reprap build event, and now the hacked vinyl cutter, makerbot, PS1’s own RepRap Mendel, and the brand new CNC tool (it’s extremely cool, but I’m not allowed to announce it on this blog yet) have taken over half of the electronics work area.

To complete the CNC takeover, PS1 will hold a monthly Automation Station: One event where people are encouraged to bring their in-progress projects for building in a communal atmosphere and completed projects to show off.

All CNC tools are welcome: additive, subtractive, mills, lasers, printers, frosters, plotters, RepRaps, and even egg-bots.  There will be an emphasis on open source hardware/software tools, but not exclusively so.

This first event will be on July 20th at 7pm at Pumping Station: One. Non-member CNC enthusiasts (and any projects they wish to share) are welcome to attend.

Build Your Own 3D Printer Workshop: June 18

repRap Mendel Prusa Chris donated to PS:One

Update (2): run time clarification – this workshop runs from 10am to 6pm (or really, until the machines are complete).  These are complex machines – expect for this to take a while.

Update: just to be completely clear: this event is open to anyone who signs up via Eventbrite. PS:One membership is not required.

We’ve got a fever, and 3D printing is the cure!

On June 18, PS:One member Chris Jansen will be holding a build-your-own RepRap Mendel Prusa 3D printer workshop.  Workshop cost will be $100 (for materials).

If you don’t know what it is, a RepRap is a 3D printer that can print many of it’s own parts. A REPlicating RApid Prototyper.  If you have one RepRap, you can make more RepRaps, and even give them to your friends!

At the workshop, we will receive the parts and support to build the X-Y-Z gantry for a RepRap Prusa – all the plastics, mechanicals, belts, pulleys, MDF build platform, etc. At the end of the day you will have a fully-built XYZ body and build platform that just needs electronics installed and programmed to get up and running.

PLEASE NOTE: To complete the build, you’ll need to purchase another $200-$300 worth of electronics and stepper motors and hot ends (price varies depending on the bells and whistles you choose).  Please see the wiki page for a listing of electronics not included in this workshop. If you bring your own electronics along with you, assistance may be available to get your electronics installed (no promises).

What: Build your own RepRap Mendel Prusa X/Y/Z gantry and build platform

Where: Pumping Station: One 3354 N. Elston Ave, Chicago, IL

How much: $100 per person (Limit 20).

A great introduction to 3D printing and the RepRap Mendel Prusa we’ll be building on 6/18:

Transmissometer: measures concentration with lasers

I’m starting a company that makes campfire scented cologne, and to solve a problem in my production process, I built a transmissometer.  Here is the video Aaron Kowalski and I made with Element 14‘s support:

Here are more details on the device, including photos, schematics, and source code.

Thanks to everyone who helped out with the build and filming!

Equipment Labeling

We have a new equipment labeling and tracking system!

Here’s how it works – every major piece of equipment has a wiki page and a label.

The label has 5 pieces of critical info:

  1. Name of the Tool
  2. QR code and URL (of the wiki page)
  3. Owner – (PS1 or individual)
  4. Certification Required (RTFM) or No Certification Required
  5. Do Not Hack (DNH) or Hacking is OK

The Wiki page is a place where you can learn more about the tool, whether it is functioning, safety documentation, person to contact, certification information, etc.

Feel free to go into the equipment pages and add detailed usage information.

Thanks to the generous folks at LVL1 and Labitat for sharing wiki code and labeling schemes with me – I stole a bit from both systems to come up with the PS1 system.  Thanks to Dan Meyer, Shawn Blazak, and Tim Saylor for putting in a few hours of hard work Sunday afternoon to get the system up and running. Thanks also to Nathan Witt and Jim Burke for smoothing out bumps in the wiki template and creating video, respectively.

President’s Farewell Letter

Today, January 18, 2011, is the last day of my tenure as President of Pumping Station: One, and I’d like to take this opportunity to say to the PS:One 2010 Board of Directors, PS:One members new and old, our community, our friends, and our neighbors:
Thank you.

Thank you for giving me the opportunity to serve your community for the past year as president of the City of Chicago’s hackerspace.  Thank you for the hard work, enthusiasm, and ideas; the good, the bad, and even the crazy ones you contributed to keep us alive this past year.  In 2010 we experienced near-catastrophes, but we also experienced many more triumphs.   Continue reading President’s Farewell Letter

Membership Rate Changes

On Tuesday night, the Board of Directors voted 6-0-1 (Aye, Nay, Present) in favor of the following changes to the Membership Rates:

  • Starving Hacker: $40/month (from $30)
  • Full Member: $70/month (from $50)
  • Annual Full Member: $700 (from $500)
  • Pay what you will membership: completely new

These rates take effect immediately.  There is a grandfather clause: any current members who choose to remain at their current rates are free to do so indefinitely. However, if that member misses payments, changes membership class, or makes any other changes to their membership status, they will be obliged to pay the new rates.  Additionally, the grandfather clause does not apply to annual rates – all members paying the annual rate will make their next payment at the new membership rate.

The pay what you will membership is intended for persons who either wish to pay more to support our organization or simply cannot afford to pay our full rates.  Note: access to the mailing lists, space, and tools is still determined by membership rates as published on the Becoming a Member page – we aren’t offering full access for discounts via this option.

Explanations of why we made this difficult decision after the break. Continue reading Membership Rate Changes
