Last night Hong Kong hackers descended on BootHK wielding soldering irons and cutting tools during the weekly BotJam meetup. They had plans (and parts) for putting together 20 Mintyboost AA powered USB chargers to send to the Tokyo Hackerspace for the earthquake victims who have spotty or no power still.
Over a dozen people learned how to solder and basic circuit board assembly. This meetup is happening regularly on Tuesdays at 8, with a wide range of projects being worked on by a solid group of people learning about all things hardware and software.
