Introducing Laser* Tag Badge from dani.pink, a brand new**, unofficial badge for DEF CON 33! *no actual lasers, just invisible somewhat-focused IR beam **other people have done similar things before, but this is a bit different because it has an LCD and a convoluted QR code online scoring system! Discord server (to get more info and coordinate pickups): https://discord.gg/sNhUzJu97M Game Wear badge during Defcon. Earn points by firing at other people you encounter wearing the badge. Score more points for tagging more unique other people each hour (you can tag the same person up to 5 times per hour) Periodically scan QR code on badge screen to sync to online leaderboard. At-home mode allows for use after the convention, with simpler scoring and no QR code sync. Hardware RP2350 (on Waveshare RP2350-Zero daughterboard) VSLY5940 narrow-beam IR emitter + generic IR receiver 30 RGB LEDs Photoresistor for automatic LED brightness control 1.28" round LCD (240x240) with GC9A01 driver (removable/reusable) 5-way directional switch + separate SYNC button Rechargeable 18650 battery Vibration motor Piezo buzzer 2x SAO ports (power-only, unless you manually solder new wires) Depending on how soon you pick up the badge, you might end up with a slightly-worse-looking GREEN PCB and/or BLUE display module (supply chain and production times and all that stuff) Caveats Not as good as real laser tag because: Badge has no visible laser dot to help with aim IR beam is not as narrow as real laser tag (to make up for lack of visible laser dot) Scores aren't synced to leaderboard in real-time--each player needs to press a button on the badge to generate a QR code and then scan it to upload their record of hits to server LVCC is not as good as a real laser tag arena due to: 1) ambient light, 2) reflective surfaces. The increased ambient light makes the maximum overall shot range less (especially around sunlight), and the reflective surfaces make it so shots at short range may "hit" even if the aim is bad. This is an order to Pick Up a badge in-person in Las Vegas! Pickup options: 1.
