For Bay Area Maker Faire this year, I created some giveaway keychain PCBs based on the EMF Explorer Badge, and folks got to practice soldering using iFixit's Power Series portable soldering stations. Big thanks to @oshpark for producing the circuit boards, and @iFixit for sharing their soldering irons for folks to use. Catch me at an event, and I might just have a few left to share. #ifixit #oshpark
