After looking around, I found the code at http://mitat.tuu.fi/?p=78 …; however, it’s not compatible with Arduino 1.0.
I am starting to research what I need to change to make it compliant with the new IDE. Hopefully, it won’t take much…
Unfortunately, this does not work with Arduino 1.0 code, as is, due to changes in Wire.send() & Wire.receive()… for those new to Arduino, change all the above to:
Wire.write() & Wire.read().
It will save the headache of going through the code twice.

Thank you, RobertC, for the reply. How long a run time do you get for the 2200mA rating?
I saw somebody use sub-C type battery packs with 5Ah rating… how in the world are we supposed to supply power to this thing without weighing it down (i.e., SLA), or spending a small fortune (LiPo, LiFe, etc)?
Using those figures, here’s what I come up with:
P = IxV = (6x3)x6 = 18x6 = 108 Watts
That’s outrageous! 18A constant supply, I cannot find a battery that will fit that requirement AND fit on the body.
Right now, I have 6V @ 7Ah. 7Ah/20 = 0.35Ah constant supply. Not even close…
First, this thing is fantastic & well-built, I love it!
Now, on to powering this thing. It’s been years since I’ve dealt with the formula to compute total power requirements, so I am really messing things up trying to figure this out.
Is the “free-run” 450mA the nominal draw when the motor is in use? Or, would I have to figure power requirements from the maximum draw of 6A?
No public wish lists :(
