Ive been toying around with some components over the weekend, had a few boxes, and started tearing them up, seeing what i could do to them. I had a few dead m401 batteries which allowed me to get some atty connectors... unfortunately, i wasted 2 of them perfecting the deconstruction of the battery. This is what 3 days of toying around got me... its nothing special, but boredom got the best of me. It's simple in the fact that the only difficult thing in it is the LED wiring. if it wasnt for that, this would have taken me about 20 minutes and 3 solder points (led took me to a whopping 6 solder points, lol). I bought a 5v LED, so no need to throw a resistor on it... but i didnt realize it was a high intensity LED, so i probably should have just because. in all, this cost me about $12 including a new 6' USB cable that was on clearance... the LED was the most expensive part at $5.
