[Lab] Introduction and question

Hello Jeffrey,
    No I have never used an arduino before. I wanted something powerful and cheap so I chose the chipkit. I first heard about the arduino, and the idea of a hacker space, in a tedtalk I watched recently. Think it was called "we are all makers".

   The motors are all 2-3 HP 2500-4000 RPM, 15-20 A, and weigh 15-40 LB.

I'm going to have to get some to a lab session somehow so people can play with them.

Hi Tony,

Welcome to the list!  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...

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...

Hello builders and thinkers,

   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.

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.

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.

Let me know if anyone is interested.

Hope to attend a lab soon and meet you all.
