Slightly Annoying Rubik's Cube Automatic Solving Machine
S.A.R.C.A.S.M is a 3D-printed, Teensy-powered robot that scans, solves, and sassily comments on a Rubik’s Cube.
This repository contains the code and schematics of the build.
Additional details may be found on the Teensy forum thread:

- Teensy 4.1 main controller + ESP32-CAM for image capture.
- ILI9341 display with custom 2D&3D graphics, animations, and lip-sync.
- Stepper + servos for cube handling with position sensors to detect faults.
- RGBW lighting synchronized to audio.
- On-device TTS (espeak-ng) with a collection of sarcastic lines.

A slight modification of Teensy's core is required in order for the whole code to fit in RAM.
Edit cores/teensy4/usb_serial.c and cores/teensy4/usb_serial2.c and, in each file, remove the DMAMEM attribute in front of the definition of the txbuffer[] and rx_buffer[] arrays.
This is a work in progress. The repo is currently in a very messy and incomplete state (and will most likely stay that way until I find some time to work on it...). Sorry !
