Making another attempt to reactivate my OLED business card project. Due to lack of time and other priorities, I had to stop it for several months. I think that I’ve find an optimal hardware design and power source. Given limitations of ATtiny85, I started writing firmware in assembly, now I am starting it again in C.
The board on picture was assembled to allow me work at kitchen table while watching my kids :)
