we prototype an e ink bonnet for raspberry pi and friends, drive displays over spi and i2c, and try a particle tachyon board to push cellular updates with zero wires. image dithering tests, a local solar powered llm that turns daily news into art so you can glance instead of doomscroll, and early ideas for portable e ink graffiti boxes. spi and i2c bring-up, dithering workflow, cellular update loop, and next steps to get the board into the shop. @particle #tachyon @Qualcomm #dragonwing #eink #opensource Visit the Adafruit shop online - http://www.adafruit.com…
