Forum member flok posted on the PJRC Forum about building a Eurorack interface for the Teensy 4.1. The reason was simple: no kit or ready made Eurorack-to-Teensy board turned up, so the work started from scratch. The first attempt is a board with a DAC and an ADC that handle the

Bo Made It measured what it costs to push an e-paper display far past its normal refresh rate, in a video published on YouTube. The test board is the Waveshare ESP32-S3-ePaper, running a custom display driver and a Game Boy emulator at 30 frames per second. The video breaks the p

Sebastian-Ion Nae has put two small neural networks on a Raspberry Pi Pico 2 W, and published the project on GitHub. One network is a world model: given the current frame and an action, it predicts the next frame and the reward. The other is an actor that looks at the dreamed fra

SylphideOS is a general purpose GUI operating system for microcontrollers, written by a developer named Thomas. The look owes a lot to the early Macintosh, with a desktop and windows driven through a framebuffer. Underneath it runs on the FreeRTOS kernel, which raises the questio

Kristijonas Adomaitis has published Kadmos-1 on GitHub, a decoder-only transformer language model with 45.8 million parameters that holds a short conversation and writes small Python functions. The architecture, tokenizer and weights were built in the repository from random initi

Julian Horsey at Geeky Gadgets writes about a handheld radar built by NorthWorks Lab, modeled on the motion tracker from the movie Aliens. It pairs an ESP32-S3 microcontroller with an LD2450 radar module, a small display and a speaker. The LD2450 reports the position of moving ta

doomformer is a project from alp (@mottopanikeiku) that compiles an integer neural network into a DOOM map. Voodoo dolls do the arithmetic. Light levels and plane heights hold the values. Every value the map exposes is read back and compared against NumPy. One map puts 1,355 vood

Stephen Cass built a lockbox that opens only when the right gesture is traced with a magnet, and wrote it up for IEEE Spectrum. The sensor is SparkFun’s $100 magnetic imaging tile, a small-run board based on work by Peter Jansen. It carries an 8-by-8 grid of Hall-effect sensors t
