NERP tonite: Pick-n-Pi

NERP is Not Exlusivey Raspberry Pi, the small computer interest group at Pumping Station:One in Chicago.

Several members of Pumping Station:One are collaborating on a project to produce a pick and place machine. PnP machines are robotic assembly devices that place electronic components on circuit boards as part of the soldering process. The software that will run the machine is made of several distinct subsystems including motion control and computer vision. Jay Hopkins has been doing some experiments to determine whether a Raspberry Pi can serve as the on-board controller for the machine. Tonight he’ll show nerp some of his progress. Teaser: OpenCV _will_ compile on the Raspberry PI!

NERP meets at 7pm 2-25-13 at Pumping Station:One, 3519 N. Elston Ave. in Chicago. NERP is free and open to the public.

your jealousy is understandable

… because how awesome is my laptop now?

It’s a wave…

… of bunnies!

I have long loved Kozyndan’s ‘Uprisings.’ It’s a play on Hokusai’s ‘The Great Wave off Kanagawa,’ with bunnies. I got my anodized aluminum Macbook Pro, and saw someone had laser etched theirs in a laser cutter. I thought this was a great choice to put on mine. I bought the poster, had it scanned at a shop with a large-format scanner, pulled it into the Gimp open-source graphics package (comparable to Photoshop), and messed with it a fair amount. Then I brought it into PS:One and etched it on our laser cutter. I have to give credit to Will McShane for his assistance in showing me how to edit the image and operate the laser cutter. Both operations fall in that category of things I do rarely and are sort of complicated, so my memory doesn’t hang on to them well. It came out perfectly. Thanks so much for your help, Will.

[Addendum: I posted a more complete account of the process on my personal blog.]

Automation Night – Thursday, 1/10 at 7PM

Eric Gregori will be giving a talk about doing computer vision on the Android platform using the OpenCV library. It will take place at Pumping Station: One’s (http://pumpingstationone.org). Automated Manufacturing Night on Thursday, 1/10, at 7pm.

Manufacturing applications for computer vision include assembly:

And inspection:

After his talk and questions, we will discuss, repair, and build CNC machines ranging from 3D printers to electronics pick and place machines.

Thanks to Eric for a wonderful talk and to everyone who came out.

Eric included the presentation, and the links he mentioned during it, here: http://buildsmartrobots.ning.com/profiles/blogs/pumping-station-one-a-great-group-of-hackers.  He has written an article on the topic here:  http://www.embedded.com/design/programming-languages-and-tools/4406164/1/Developing-OpenCV-computer-vision-apps-for-the-Android-platform

A recorded version of the talk is available here.  Unfortunately, the video and audio quality are low.

Eric is the President of EMGRobotics (http://www.EMGRobotics.com). He is a robot enthusiast with over 19 years of embedded firmware design experience. His specialities are computer vision, artificial intelligence, and programming for Windows Embedded CE, Linux, and Android operating systems.

Automated Manufacturing Night is a monthly event where a speaker will discuss a topic related to Automated Manufacturing on the third Thursday each month. It is affiliated with the CNC Build Club (http://www.meetup.com/CNC-Build-Club/), a group where folks work on automated manufacturing machines at Pumping Station: One. It is also open to the public.

Pumping Station: One is a Chicago hackerspace located at 3519 N Elston, Chicago IL 60618.

This talk was organized by Jeff McAlvay, who is working with a team from PS:One on an open pick and place machine (http://www.boardforge.com).

Announcing the CNC Build Club

Plasma cut PS:One logo

Picture of plasma cut PS:One logo taken from buildlog.net

Last Monday’s 3D printing discussion was both well-attended and full of ideas. By the end of the night the beginnings of a few exciting new projects were starting to take shape. Since there are already several CNC projects in the works at PS:One, we decided that once a month isn’t enough to satisfy our appetites for automation.

So I’m pleased to announce the formation of the CNC Build Club, which will meet every Wednesday night at PS:One to design and build machines employing computer numerical control. If you’re interested in building a 3D printer, a CNC router or a pick & place machine, you can join up with a group already working on a design. Or come up with your own idea and recruit others to work with you!

  • Who: Open to the public
  • Where: Pumping Station: One, 3519 N Elston Ave, Chicago, IL
  • When: Every Wednesday at 7pm
  • Cost: Free ($5 suggested donation for non-members to help us pay the rent)

We’re still going to have our monthly Automation Night, which will be slightly more formal and have a guest speaker, but all other Wednesdays will be focused on getting work done on projects.

Join the Google Group for the CNC Build Club. We’ll see you Wednesday night!

Design a 3D printer! 10/29 at 7pm

When we were considering which 3D printer to get for the space, one of the suggestions was that we design one ourselves.

To start the project off, I will give an account of the 3D printers currently used in industry (http://jeffsinventions.com/?p=1328), including ones that print metal:

Then, Jeremy, from TinyWorkshop, will talk about consumer 3D printing technology.  Here is a link to the slides from his talk.

About 30 folks turned out to the event and many interesting ideas were suggested. We decided to focus on two parallel projects:

1) Make a device that 3D prints electronics. We have begun to make prototypes for this project (http://jeffsinventions.com/?p=1589).

2) Start with an existing 3D printer design and iterate on it along a number of axes, including:

  • Extrude different materials (e.g., chocolate, general purpose binder)
  • Adapt it to make molds
  • Add encoders for linear feedback
  • Add a closed loop heater
  • Make it general purpose so that different tools can be added (e.g., mill)

Bart has generously offered to donate an ORD Bot for this project.  He has started work, and a thread, about the project here:  http://www.buildlog.net/forum/viewtopic.php?f=16&t=1625.

To move forward on these projects, we will begin a weekly CNC Build Club: http://pumpingstationone.org/2012/11/announcing-the-cnc-build-club/
