This badge was made for a workshop. The main topic for the event was "upcycling" - therefore we designed the badge around reusability of old components - the legs and antennas are made from scrap electronic components (we have a lot of these at hackerspace), so are resistors and LEDs too (who uses THT components today anyways).
