I'm very surprised this instructable did not get featured or win the competitions :( Anyway, I want to charge a 6v motorcycle li battery from a 9v solar panel so I'm guessing I change some of the resistors and maybe the zenor diode? I should be able to work it out but some quick guidance would be very helpful - Thanks!

Hi,Inkjet printer will not work (different kind of toner/paint, different way of printing etc.). Only laser.Etching solutions is usually available at local electric shops (where normal components are available: resistors, leds or even plain PCB boards). Note that it is not available for on-line orders in most countries due to postage restrictions.
