We don’t normally chase after commercial products, but when I ran across this guys work, I was impressed. My favorite has to be this solar powered GPS logger. It logs your trek to a SD card and it’s oh so tiny. Other notable projects include a li-poly battery backpack for charging USB devices. (Li-Poly batteries require some specialized charging)
