FedEx Day at NYC Resistor
On the 28th and 29th of this month, biohack.me is meeting up in New York. For six hours we will be using NYC resistor's workspace to build one device. Because of the time limitations, machines like the Light Bulb PCR or a microdermal holographic implant is not possible. Please use the space below to outline your idea on what should be built (if you are attending). Registration for these ideas will be closed on Wednesday. I hope to see you there!

I'm doing something completely different, then; I'll pass on my results once I eventually get them, in case they'll be of any use to you, but there's no real parallels during dev and test. Good luck with it!
the smallest microcontrollers around for such a job are about 4x4mm in size, with LGA connctions smaller than what most people can handle.
LED's eat energy for breakfast. especially bright ones. so be prepared to recharge it pretty often.
you do want to use a battery-management controller for safety. there are great energy-harvesting ic's with battery management build-in. they also come in tiny packages like 3x3 or 4x4mm.
for microcontrollers, i would recommend against the RTC. a microcontroller has plenty of processing power to spare, and you can simply clock the μC from a clock-crystal. setting the time could be done via IRDA or by modulating data ontop of the charging transmitter.
if you need some part numbers, check on the southpaw discussion. i picked a few useful ones there. not the smallest ones , but you cant assemble those without a proper lab anyway.
