Saw this ebay auction: http://www.ebay.com/itm/12-VOLTS-MI...087?pt=LH_DefaultDomain_0&hash=item5d2856c29f
Anyone installed a secondary coil like this one? Couldn't find any posts about it in search, but I like this method of avoiding the white wire. I have a 12v/500ma front-wheel dynamo I could use, but I'd like to have power at idle. And, with that output, I could get 300-500 lumens from a couple CREE's!
Is it really as simple as building another coil and installing it in the magneto case?
PS: It'd be fun to get a mount and USB charger to make a dock for my phone for navigation/speedometer purposes! =)
