OK so I "built" a solar charger for my son's DS using this panel, http://www.harborfreight.com/solar-panel-recharger-41427.html and buying a USB to DS cord. I built an adapter to go from the power plug to a female USB being careful to get the polarity correct. When I put it in the sun on the 6V 100 ma the orange charge light on the DS fades in and out. So I blocked about half the panel with a piece of paper and it glows steady. The voltage reading coming off the panel with the paper blocking it is 3.2V. The only thing I can think of is the DS is getting too much power and the overcharge protection is making it pulse on and off. And suggestions on how to fix it so I don;t have to block the panel every time?
