For Christmas 2019, I made my partner a box that displays a random poem on an e-Ink screen. The main inspiration was a short story dispenser that we came across at the Austin Public Library. After seeing this, I saw several projects on r/arduino of people making their own poem dispensers and the like. Not wanting to waste paper, I decided to make my own using the Pimoroni wHAT e-Ink display, a Raspberry Pi Zero W, and an old cigar box.
Points Delicats was my final project for a class in Computer Organization and Machine Language. The assignment required we build a device that interacts a Raspberry Pi with hardware, with the caveat that all GPIO interactions must be written in assembly. Since one of my teammates is interested in building devices for the visually impaired, we settled on displaying a braille message on a LED matrix based upon text entered into a console.
The Missing Clusterhat Tutorial
As a project, I decided I wanted to learn more about Cluster computing. The cheapest way to do this, of course, is with a cluster of Raspberry Pis. There are several truly impressive Raspberry Pi clusters across the internet, but the cheapest and easiest option I could find was the ClusterHat. The ClusterHat is a shield for a Raspberry Pi 3 or 4 which allows you to attach four Raspberry Pi Zeros as nodes to a Raspberry Pi 3/4 easily.
libDigitone is a portable SysEx library written in python for the Elektron Digitone. This library was started before the Digitone was added to the Overbridge family of devices. You can find the source code here. Future plans include translating the library into C and Swift to allow an easier integration with desktop computers and Apple devices.
