For his own reasons, [Jose Luis Monteiro] (aka [emsyscode]) decided he needed to drive the LCD on a Sony CDX-A250 car stereo’s front panel using an Arduino. There’s probably a …read more Continue reading Reverse Engineering A Sony Car Stereo LCD
There are lots of reasons to run LLMs locally, from privacy concerns to just wanting to futz about with the technology, but if you want to run the big models, …read more Continue reading No GPU, No Problem: Flagship LLMs on a GPU-less Teenaged Server
The RP2350 is actually a pretty secure chip, all things considered. It has secure boot, ARMv8’s TrustZone to split secure and non-secure execution, and you can permanently disable debug — …read more Continue reading Laser Your Way into Debug Mode on the RP2350
This article is written on an open-source operating system, but not an open-source machine — the BIOS isn’t open-source, and even if it were supported by the coreboot project (formerly …read more Continue reading Coreboot Hikes the Bay Trail to DRAM Initialization
When it comes to clockwork, there is a spectrum — some people love the ticking, and some people hate it, while most fall into the broad middle of indifference. Once …read more Continue reading Printing a Clock Fit for a Pope
It would not be at all original to declare that Python is the new BASIC. Like BASIC, it has been the first programming language for a whole generation of coders, …read more Continue reading CircuitPython Goes Turbo With Precompiled Functions
If you’ve never heard of the Spin Semiconductors FP-1 digital signal processor chip, don’t worry– that just means you haven’t been deep into guitar petals and audio effects hardware lately. …read more Continue reading Spin FV-1 Emulator Simplifies Sound Pedal Development
You want Retro? We did, when we started our retrocomputing challenge. [Peter] decided that transistors weren’t retro enough, and sent us this lovely homebrew relay computer, complete with 16- bit …read more Continue reading 2026 Retrocomputing Challenge: 16-Bit Homebrew Relay Computer
Nintendo has made many game consoles in its long history — one that famously overlaps that of the Ottoman Empire — but only one of them was ever Super. It’s …read more Continue reading Hand-Coded ASM Powers Homebrew SNES Game
Expressif might not have intended the ESP32-S3 to become an emulation powerhouse, but that’s certainly what has happened. The little microcontroller seems perfect for recreating the Game Boys or Game …read more Continue reading This Circuit Sculpture is an ESP32-Powered Console
