Tonight's Meeting

[Tony Buser]

No real agenda for tonight.  I will be bringing my Arduino and Proto Shield that I assembled http://ladyada.net/make/pshield/index.html and my goal for tonight is to get this EasyDriver http://vimeo.com/1708760 and stepper working to control the 3D scanner turntable that I've been working on and off on for the past few weeks.

May also be doing a phone interview with a reporter for a possible article she'd like to write about Berks CoLab for http://keystoneedge.com

Also, Reading Regen would like to do a project with local schools involving recycling old small solar panels to build what sounds like BEAM robots http://en.wikipedia.org/wiki/BEAM_robotics  Maybe we can talk about ideas about how we could help them.

 I have too much work i need to catch up on so i will see you Saturday.
 
This sounds extremely interesting and i have quite a few ideas especially with the solar projects. Good luck with your steppers and see you Saturday.

No problem.  We probably could have used you last night, though.  We ended up working on Rich's 3-axis stepper driver for the CNC machine he is building.  We managed to figure out how to wire it all up and got it working with the Mach3 software (connected via parallel port).  Unfortunately, it appears on of his steppers might be damaged and it doesn't look like any of the steppers from the junk pile would have enough power to use on his CNC machine.  (I think he's using 2.5A NEMA 23 steppers)
