The previous work with the proof-of-concept is posted here and runs with 32 cores.
The badge version of this project will take shape on this project page, and will have 64 cores. The project name is a nod to my favorite 8-bit computer, the Commodore 64.
The vision for the badge follows:
1) 8x8 core memory array will be center stage.
2) Each core is backlit by an RGB LED.
3) The core array will be driven with transistors, directly tied to a slew of GPIO on an Arduino compatible microcontroller in order to be accessible and programmable by anyone with basic Arduino experience.
4) A magnetic stylus will be easily transportable and stay with the badge.
5) Battery power will be 3 "AAA" or "AA" or LiPo.
6) No buttons allowed! But reed switches and hall effect sensors are fair game.
My aim is to keep the badge simple and clean looking, so the focus is entirely on the cores themselves. That is, after all, the focal point of this project.
That said, I'm open to ideas and collaboration! This will be my first end-to-end surface mount PCB design project, so I'm trying to limit the rabbit trails. The prototype will most likely use an existing 8x8 RGB LED array and Arduino-compatible board in order to simplify the board design work.
