About
[[https://git.taktpraha.cz/trimen/tctb_hw|HW repository]
This board is meant to be used as part of home automation for controlling devices via IR, thanks to ESP32 and pin headers users can simply add other sensors to the system.
Thanks to the buck-boost converter, the device is capable of utilizing the full capacity of the battery.
For propagation purposes we came up with a game, that can be played at events such as conferences, where we hide several of those boards and players will try to find them by RSSI of Bluetooth signal. The find of the device is confirmed via IR. The successful capture of all hidden devices unlocks other features such as TV-be-gone functionality. Devices will be reporting progress via WiFi to create a leaderboard.
