Badges contain blinking lights and 2-way communication, so the badge can tell you if there are friends around that also wear their TBD friends badge. Soldering is done using solder paste and a hotplate. Takes about 1 hour for beginners (which mainly depends on my divergence when I talk you through it). Record time is 12 minutes. Badges are donation-ware - Pay whatever you like. Materials costs are currently about 2 euro https://github.com/hackwinkel/ /media/e/d619de5f1be1/tbdbadge.pngthe0 (he his him)/event/detail/tbd-badge-soldering-workshopsfalse2025-12-29T14:00:00+01:0014:0001:00TBD small39c3-possibly-tbd-friends-badge-soldering-workshopen, deotherpossibly TBD friends badge soldering workshop https://github.com/hackwinkel/There may still be some version 1.5 and version 2.0 TBD friends badges left to solder.
