About this project
About this project
A round AMOLED badge you wear, which spends most of its usefulness as a Bluetooth HID pointing device: hold it and the gyro moves the cursor, or rub the glass like a trackpad, with a ring of twelve Excel keys such as F4 that a phone keyboard cannot send over RDP. The same firmware holds a swiped clock with timer, stopwatch and alarm, a 16 kHz ADPCM recorder that exports about 52 minutes as WAV over a read-only USB drive, bricks, pinball, a tilt maze and accelerometer fidgets. It targets the aluminium-cased ESP32-S3-Touch-AMOLED-1.75C with 32 MB flash; the plain 1.75 lacks the flash and the RTC, so this one sets its time from the network. ESP-IDF 5.5, plus a desktop simulator.
