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.
Usually databases are treated primarily as fairly dumb data storage systems, but they can be capable of much more. Case in point the PostgreSQL database and its – Ada-based – PL/pgSQL programming language, which allows you to perform significantly more complex operations than would be realistically possible with raw SQL. Case in point the implementation of a Kalman Filter by the folk over at Traconiq, which thus removes the necessity for an external filtering pipeline. Using a Kalman Filter is highly desirable when you’re doing something like vehicle tracking using both dead-reckoning and GPS coordinates, as it filters out noise that can be the result of e.g. GPS reception issues.
Nathan Ladwig has got the ESP32 decoding SPDIF quite effectively, using an onboard peripheral outside its traditional remit. The project allows an ESP32 to work as a USB audio device or take an S/PDIF signal as input, and then transmitting that audio stream over RTP.
