Following his successful creation of a 7:1 scale Arduino UNO Rev3, creator UncleStem has developed a matching oversized "turtle robot" designed to operate with the massive board. Using a standard-sized turtle robot as a blueprint, he scaled up every component by utilizing functional equivalents, such as high-power motors intended for kids' ride-on vehicles and 3D-printed shells that mimic the appearance of original miniature parts. The resulting mega-robot functions identically to its small counterpart, using an ultrasonic sensor on a servo mount to navigate around obstacles.
The author explores the potential of running an AI agent framework on low-cost hardware by testing MimiClaw, an OpenClaw-inspired assistant, on an ESP32-S3 microcontroller. Unlike traditional AI setups, MimiClaw operates without Node.js or Linux, requiring the user to flash custom firmware using the ESP-IDF framework. The setup integrates with Telegram for interaction and utilizes Anthropic and Tavily APIs for intelligence and web searching. Despite the technical hurdles of installation and potential API costs, the project successfully demonstrates a functional, sandboxed, and low-power personal assistant capable of persistent memory and routine tracking.

Something similar to the Spotify Car Thing, built with a cheap ESP32 Screen. Connects to your Spotify account and displays your currently playing song with its album art.
AI-On-The-Edge-Cam is an ESP32-S3 board with a 2MP camera, microSD card, WiFi, BLE, and PoE Ethernet connectivity designed to digitize legacy utility meters such as water meters, gas meters, or electricity meters that require manual onsite reading. It supports Tensorflow Lite, has a web interface, and integrates with Home Assistant.
Desktop clock showing time as a DCF77 bistream. The TD-FDCF01A is a table clock that displays time as a DCF77 60-bit stream. It's the opposite of a radio controlled clock - instead of receiving the DCF77 signal, it *displays* the time as that signal. It uses 60 RGB LEDs to show the time, date, and other information, and features a serial interface for customization.
The M5Stack Cardputer v1.1 is a high-performance card computer featuring a StampS3A microcontroller, 56-key keyboard, 1.14-inch TFT screen, and various interfaces for expansion and control. It's ideal for rapid prototyping, industrial control, and IoT projects.
I'm a dedicated hardware developer with a passion for creating innovative, open-source technology solutions. My focus is on modernizing retro computers, developing communication devices, and advancing keyboard technology. Join the journey to support and contribute to these innovative projects.
Lopaka is a web-based tool for creating graphics and user interfaces for electronic projects, supporting various display types and libraries. It allows users to create images and interfaces visually, with generated source code for integration into projects.
The author describes their project of replacing a Digital Pet from Tiger, a cheaper Tamagotchi rip-off, with an Arduino Nano, an OLED screen, and 6V batteries. This is a prototype for their thesis in New Technologies of Art. They detail modifications like eviscerating the original device, integrating a new battery holder, and making adjustments to the case. The final goal is to create a working game loop display on the OLED screen.
