### [How we made the Supabase Select 2026 badge](https://yomu.fyi/post/how-we-made-the-supabase-select-2026-badge.md)

Supabase gave every Select 2026 attendee a programmable badge based on the Pimoroni Tufty 2350, with an RP2350 microcontroller, color screen, rechargeable battery, Wi-Fi, Bluetooth, and five buttons. A firmware bug drained all batteries during shipping, requiring bulk charging with 30-port USB hubs in 14 batches over 56 hours and individual firmware updates. The venue Wi-Fi failed, so the schedule was synced via a hotspot, two badges at a time, one minute each, totaling seven hours. Attendees have since repurposed the badge into projects including a live flight tracker, an arcade game about database vacuuming, a food finder app, a music note collection game, and a tiny on-device language model. The post provides resources for hacking the badge: a first-app guide, a Claude Code project kit, a virtual badge, guides for C or Rust firmware, and a contest with Supabase credits and conference passes.
