Microsoft Kinect Presentation – CNC Build Club

tracking_capture

Thursday, May 2 @ 7:00pm

Presentation

This week we have a presentation from Jarvis Schultz on using the Microsoft Kinect motion sensor input device and other related devices.  He is going to give an overview on how they work, what kind of data they can produce, what software is needed to interact with them, and what you can do with the data once you have it.  He will include some live demos of what the data looks like, and what you can do with it.

Jarvis is a fourth-year PhD student in Mechanical Engineering working on robotics at Northwestern University.  He is part of the Neuroscience and Robotics Laboratory, and he has been working with the Kinect since it was first available, and it has become an integral part of his PhD research.  Further information is on his research webpage in case you are interested http://nxr.northwestern.edu/people/jarvis-schultz.

Thanks to Steve Finkelman for arranging this.

CNC Router

Starting Pile Of CNC Parts

Following the presentation and discussion we are going to continue with the CNC Router project. We are going to add the limit switches for the X,Y and Z axes. Limit switches can protect your machine from over travel, but also provide an accurate and repeatable home position.

We are also going to setup Mach3 as the machine controller. We will try to do this while hooked up to the projector, so everyone can participate in the process and learn how to do it. Mach3 is a professional level commercial controller and is a huge step up from the typical DIY solutions, like GRBL.

After a few projects with Mach3 we will probably also install EMC2 which is an open source, Linux based alternative to Mach3.

Last Night’s CNC Build Club

DSC00514

We had a great meeting last night.  We had over a dozen people working together to wire up a CNC control box.  At one point we had three soldering irons going at the same time.  Here is the pile of parts we started with.

Thanks to Chris, Matt, Aeva, Patrick, Donald, Steve, Jason & Alex, Cat, John, Will, Gabe, Norm, Allen and Colin.  Next week we will be testing the motors, adding limit switches and configuring the software.

We will start with Mach3, then switch to EMC2 when we find a dedicated PC for that.  Chris and John I think mentioned they do time at Free Geek.  I am sure they could find a little PC.

Special thanks to Automation Technologies Inc for giving/lending all the parts.

CNC Build Club

Automation Technologies 3D Gantry

The CNC Build Club meets just about every Thursday at 7:00pm.  This is a weekly meeting of Chicago area people passionate about designing, building and learning how to use digital fabrication equipment.  Non members are welcome .  Each meeting starts with a round robin introduction followed by a little discussion and often a presentation or training session.  We also often have a group project going on.

This week we are going to start putting together a small CNC milling machine.  The machine was lent to us by Automation Technologies Inc.  Right now the machine is just the mechanical platform.  We need to add the motor controls, limits switches and setup some software.  The goal is to create an easy to use work center that we will do some projects on.  The plan is to sell the machine at a discount to someone in the group when we are finished. If you don’t know anything about CNC, don’t worry, you can still help.  The goal is to teach, learn and use.

Automated Manufacturing Night – Thursday, 3/21 at 7pm

Mike Vasquez will be giving a talk “The Printed Athlete – How 3D Printing is Changing the Face of Sports.”  It is free and open to the public.

Slide1

Over the past two decades 3D printing has radically shifted the way that many industries design new products.  The medical field uses the process for creating bespoke hearing aids and aerospace companies use it to design more efficient aircraft.  However, one of the sectors that is on the leading edge of this revolution is sports.  All the major sporting goods brands have started to adopt the technology.  From 3D printed high end parts for F1 race cars to multi-colored 3D printed footwear prototypes at Nike; the opportunities offered by the new manufacturing process has the chance to transform how athletes and customers interact with the games they love. This talk focuses on how 3D printing technology already has and will continue to revolutionize sports using examples from Mike’s time at Burton Snowboards and Loughborough University’s Sports Technology Institute.  Additionally topics such as the future of the technology and growing areas of innovation including mass customization and protective equipment will be discussed.

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!

your jealousy is understandable

… because how awesome is my laptop now?

bunnywaveresults1

It’s a wave…

bunnywaveresults2

… 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.]

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:
YouTube Preview Image

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/
