So you're using a chipkit uno: have you previously used an Arduino? I've been looking for comparisons between the two. I did find an article that said the chipkit performs better than the arduino except for floating-point arithmetic... not sure how important that is...<br>
<br>The DC drive motors sound pretty nice. Do you know at what voltage they are rated? I'm with the ARISE robotics lab at uOttawa, and we've got a a few projects that require motors, but it would depend on the type...<br>

Hello builders and thinkers,<br>
<br>
My name is Tony Elwood. I've been following the mailing list for a few weeks, eavesdropping on all the interesting craziness you people have been up to. I have been building and inventing things since I was a kid and had a box of wires, batteries and lightbulbs.<br>
<br>
Just getting back into it now playing around with a chipkit uno arduino based on microchips 32 bit chip. I built a shield out of treadmill parts to drive an 8x8 led matrix. Amazingly it works.<br>
<br>
I do service for a fitness company and we are cleaning out stock of obsolete parts. Does anyone have a use for treadmill drive or incline motors. We have a big pile that will be scrapped. Many of them are brand new. I may be able to get some for free. The drive motors are dc, 1.5-3 HP. The linear actuators are slow but high torque gearbox ac motors with wormwheel shafts on them.<br>
<br>
Let me know if anyone is interested.<br>
<br>
Hope to attend a lab soon and meet you all.<br>
-Tony<br>
