Instructables user [SirGalaxy]‘s Tinycorder is a multi-purpose device that can sense its environment in a variety of ways, despite its namesake, and serves as a good base for those wishing to develop their own firmware, with [SirGalaxy] also planning future developments such as a buzzer and a battery indicator.
The device contains an ESP32, alongside an AS7341 light sensor, an air quality sensor and a weather sensor, and its battery and 400×240 display are both very low on power consumption.
The portable nature of the device and its varied functions recall the functions of the Star Trek tricorder and other multi-purpose testers, and the Tinycorder’s features can be adapted for other purposes in the future.
