I have a sort of it on my bike. My dynamo gives 6W @ 12V, which is exactly 500mA that Neo needs for fast charging. I use a standard car charger and a four transistors-converter to direct current with it. I don't have a Neo yet, but my phone does charge.
The problem is you hardly would ride more than an hour per day, and the dynamo is heated a lot, I don't think it's good for the trunk. 2008/2/11, Schmidt András <[EMAIL PROTECTED]>: > Today we were talking about new generation of portable personal > computers (yes, that is OpenMoko :-) with friends.
