zclaw is a personal AI assistant running on an ESP32, backed by Anthropic, OpenAI, or OpenRouter. It allows for monitoring and control of connected devices via Telegram, scheduling tasks, and creating custom tools, all within an 888KB footprint.
This article details a project to create an atomic clock using a cheap wall clock movement, an ESP8266 processor, and an EERAM chip. The project involves gutting the clock movement, controlling the hands with pulses sent to the motor, synchronizing with an NTP server, and using EERAM to store the current time for accurate timekeeping even after power loss. The author also explores potential artistic applications beyond simply telling time.
Rafael Ben-Ari has created AI-generated newspapers, including a tech news feed and a retrocomputing paper based on SimCity 2000, using a suite of LLM agents for reporting and editing. This allows for highly niche publications tailored to specific interests.
This Hackaday article discusses the historical significance of the Atari 800 and 400 computers, released in 1979, and their impact on the early home computer market. It highlights how the Atari 800, with its music synthesizer, bit-mapped graphics, and sprites, compared favorably to competitors like the Apple II, Commodore PET, and TRS-80.
John McNelly developed ADSBee, an open source ADS-B receiver based around an RP2040, to decode aircraft monitoring signals. It supports both 1090 MHz ADS-B and 978 MHz UAT protocols and is available in various form factors.
Brow6el is a terminal web browser that uses sixel graphics to display a fully graphical web browser within a terminal. It renders webpages headless using the Chromium Embedded Framework and converts the output to sixels.
An article discussing the microphone found on the Sipeed NanoKVM, explaining it's presence due to the board being based on an existing development board and how it could be useful for troubleshooting.
A Landel Mailbug email appliance was repurposed into an AI console using an ESP32 microcontroller, text-to-speech, and the ChatGPT API.
A project by Martin Pittermann demonstrates how to build a sophisticated ultrasound sensor using a Raspberry Pi Pico and basic components, employing Frequency-Modulated Continuous Wave (FMCW) radar techniques for distance measurement and potential wind speed detection.
Anfractuosity built a hyperspectral camera, the Waverider, using a miniature USB spectrometer, a stepper-driven x-y stage, and a Raspberry Pi Pico. It scans spectra one pixel at a time, taking nearly 19 hours for a 400x400 image but capturing more than just RGB values per pixel.
