The “Mac Nano” is a very small Linux computer powered by the Raspberry Pi CM0, built by Sipeed community developers. Not a lot of information appears to be out – check out this post on X (formerly Twitter).

The guidelines for using AI tools when contributing to CPython has just been updated. They are a must read, whether you’re an existing or aspiring contributor. tl;dr: you’re still responsible for what you submit See more in the Python Developer’s Guide. Via LinkedIn.

The Small Things Retro blog presents the fifth installment of the 80386 series. The FPGA CPU is now far enough along to run real software, and this post is about how it works. z386 is a 386-class CPU built around the original Intel microcode, in the same spirit as z8086. The core is not an instruction-by-instruction emulator in […]

When security researchers want to understand what a modern processor is really doing with the kind of detail that determines whether attacks like Spectre and Meltdown are possible, they usually run their experiments on top of an operating system that was never built for the job. They open up macOS or Linux, patch the kernel […]

AUDIODiWHY looks to use an ATTINY1616 microcontroller for ADSR (Attack, Decay, Sustain, Release – the basis for audio synthesizers) by  using TJimmyChonga‘s earlevel C++ library. It which abstracts analog synthesizer ADSR functionality into a compact C++ library. Looking over the code, I guessed it might be easy to use an ATTINY1616 —that’s a <$1USB MCU, folks–to create an […]

The symbol of wealth from the 80s just how you remember it – comically large. The Motorola DynaTAC was the first commercial cell phone and, adjusted for inflation, cost nearly $13,000. The phone was…substantial. Riffing on the size, Arnov Sharma built the Motorola DynaTAC MAX. Currently the massive phone works as a sound board and […]

FRANK HDMI Sound is a small HDMI video and audio driver for the Raspberry Pi RP2350, packaged as a Pico SDK library. It outputs 640x480p60 video from a 320×240 palette-indexed framebuffer and embeds 32 kHz stereo PCM in the HDMI data-island stream. No external DAC, no separate audio path. The TMDS encoding core is based […]

Voice Stick turns an M5Stack StickS3 into a Bluetooth push-to-talk input device for macOS. Hold the front button on the StickS3 to record. When you release it, the macOS menu bar app sends the audio to ASR, shows the recognized text, and pastes the final result into the currently focused input field after a short […]

WCH-Serial-ISP provides WCH Serial ISP programming for use with WCH CH32V203 ICs under an MIT license. This microcontroller series can be programmed using a WCH-link USB debug adapter. Or by resetting the chip into its bootloader (hold BOOT0 high) and a USB or Serial connection to the host software (WCHISPTool). Both programming options are undocumented […]

Racket sports are all the rage these days – people are (aggressively) enthusiastic about Pickleball, tennis courts are booked night and day (suddenly everyone has a USTA rating?). It only makes sense badminton would be next to step into the spotlight. This project from maker Navin Khambhala uses LEDs to add an extra element of […]

Do you have an old USB scanner that your computer cannot talk to? Then the yes-we-scan app is for you. Connect your scanner and get scanning. Privacy. The things you scan never leave your computer. How it works. Your web browser emulates a whole PC running Linux with open-source scanning software (SANE). It connects that […]

If your garment is free of components that can fill with water (microphones, hollow-cased switches, etc.) and can usually go in the washer when it’s not adorned with electronics, it still probably can! Agitation will increase the natural wear on any garment and circuit, so be sure to inspect the wearable for frayed threads, loosened […]

Phosphene is an open-source, menu bar-based video wallpaper engine designed natively for macOS Tahoe. It seamlessly integrates your custom videos directly into the macOS system’s native wallpaper picker using private Apple APIs, allowing you to use high-quality personal video loops as your live desktop background.  Native Integration: Bypasses clunky workarounds by tying directly into the […]

Every facility has a conference room or other meeting space. And when the door is closed, it is always a guessing game whether the room is occupied or not. This inevitably leads to someone opening the door and disturbing what is happening inside. It could interrupt a meeting or spoil an important experiment. Commercial sensor/indicator […]
