Above is a picture of the controller and power supply I have for a CNC machine I'm building. (Based on http://www.instructables.com/id/Easy-to-Build-Desk-Top-3-Axis-CNC-Milling-Machine/). I got the stepper controllers from sparkfun.com. I got the power supply from an old tape backup drive (I thought it would make a nice case and housing for the electronics). I din't have a picture of the CNC machine so far because it's been pushed off in the garage while I work on other projects. I have the X and Y access done but need to stiffel the lateral movement a little.

Things I learned: Bearings are expensive but I went to the Savers and found some used roller blades for $3 and got a bunch of bearings now. Also I didn't have plexi glass for the table and I used 1/4 melamine and it seems to be ok. I'll give more details of this project when I get back to it and can take some decent pictures.
