Lucian was on the show and tell last night and sent in these great photos of the SPUDwrite (Single Purpose User Device) –

As a person who does all of their engineering work on or adjacent to a computer, the idea of coming home and spending even MORE time on the computer for creative writing isn’t super appealing. So I made an e-paper typewriter – no browser, no games, just you and your word count. It has a character LCD at the bottom for the current line you’re typing, to make up for how slow E-paper updates, and when you’re finished you can save your file to an SD card or print it all out with the internal thermal receipt printer for redline editing. I call it the SPUDwrite (Single Purpose User Device), hopefully the first of a couple of SPUDs. It’s built on MBED and the STM32F401 Cortex M4.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. I would love to own a SPUDwrite. I’d be keen to know if you end up selling this prototype or making additional ones.
