An analog monophonic synthesizer built from ~200 components, with a transistor ladder filter and touch keys. Circuit, simulation, PCB, firmware and most of the bring-up were done by Claude Opus 5.5.

A tiny diffusion transformer running on a $1 RP2350 microcontroller can generate 128×128 pixel images of human faces.

Building wireframe polyhedra made from LED filaments, using graph theory to devise geometry and driving strategies.

Combining a deep-depthwise CNN architecture with variable quantization in BitNetMCU achieves state-of-the-art MNIST accuracy on a low-end 32-bit microcontroller with 4 kB RAM and 16 kB flash.

(Guest article on the Nous Research blog) Anecdotal evidence suggests open weight models produce significantly more tokens for similar tasks than closed weight models. This report systematically investigates these observations. We confirm this trend to be generally true, but observe significant differences depending on problem domain.
