Software, 3D model and printing files, hardware specs and instructions for building Thales.
Hardware:
1x Receiver: I use Esp32 TTGO V7 1.3 Mini - you can use any ESP32 board.
2x Sender (on board microcontrollers): Adafruit ESP32 Pico Stemma QT - S2 (avoid S3 due to incompatibility with the BNO055) (https://www.adafruit.com/product/5325)
2x Battery Charger shields for Stemma QT (https://www.adafruit.com/product/5397)
2x Adafruit BNO055 (https://www.adafruit.com/product/4646)
Taidacent MLX90393 (with few mods should easily host the Adafruit version)
4x Stemma QT I2C wires
2x SPDT Switch: https://www.adafruit.com/product/805
Set of neodymium magnets, 30mm diameter (4mm thick ones, but also 5mm is fine)
2x LiPo batteries (I used Makerfocus batteries: https://www.makerfocus.com/products/4pcs-952540-3-7v-1000mah-battery-with-jst1-25-connector-lithium-rechargeable-battery)
Screws and bolts of various sizes, possibly non ferromagnetic. Importantly, 6x half thread 5M screws, with nuts. Length of the screws should be around 45mm (we cut some 50mm ones):
Heres's one assembled controller. The picture is self-explanatory, but I will detail the process as I replicate the instrument in the next weeks:
