I have built several Adventure Bots and have not had any issues, but when I tried to build a custom 2 WD robot using IoTiny I've run into a strange problem.
Using the same "continuous rotation servo with Wheel" set from my Adventure Bot I found that they worked for about a minute before refusing to run any more.
I thought it might be just a coincidence, so I took another working set and first tried that with a EZ-B v4 controller in a Power Shell with the same "LiPo Robot battery" (after a full recharge) that I was using on IoTiny ... and those wheels worked fine
But, when I connected the wheels back to the IoTiny, the servos worked for a little while and then stopped working!
What's worse, is that I reconnected the servos back into the Adventure Bot and NONE of then worked anymore.
Any ideas?

@Alan...
30 years ago I was working as a bench tech fixing computers. My boss walked in and I had 5 * 20mb Hard drives on the table that were over $1000 each (st-225) I had one more plugged in and I said this hard drive is faulty. I plugged it in and it burnt out. He said, did you try another hard drive? I responded, yes all of them are faulty. Turned out the power supply had an extension cable that was wired back to front 12v on 5v rail and I had spent the past hour destroying half a dozen hard drives.
Anyway my lesson learned that day was, always test 1 at a time and if you try 1 and it burns out you don’t just keep plugging new ones in.
