ATMega8 based protractor with SSD1306 OLED and LIS3DH accelerometer.
Schematic and PCB made in KiCAD. Firmware project created in Atmel Studio 7. Makefile available.
Known issue - ISP header is flipped, don't try to connect it to AVRISP with kanda ribbon cable, it's gonna make a short.
Firmware is working, but some extra features are still WIP (@TODO in main.c)
Display driver made by @tibounise (https://github.com/tibounise/SSD1306-AVR) slightly modified by me to save RAM for framebuffer.
