Awesome, great job! So excited about this project. I personally need to solder my PCBs and order an ESP32-S3 to be able to start working on the firmware; is there some Rust and / or C++ stuff already semi-working to pick up or should I start from scratch?

By the way; here some updated renders for top & bottom with raytracing and Bitcoin color #ff9900 on top and bottom solder mask.
