A developer built a real-time arrhythmia detector using TinyML on an ESP32 microcontroller, processing raw ECG data locally with TensorFlow Lite for Microcontrollers. The system uses a quantized 1D-CN…
David Poblador argues that AI coding agents are replacing the informal favor economy that has long underpinned engineering teams. He describes how tasks that once required a team and a month can now b…
A maker named emadgaidi shared a design for a minimalist smart lamp powered by an ESP32 with WLED, featuring a cylindrical ribbed lampshade for light diffusion. The lamp uses an integrated LED strip a…
A developer released PySpell, a sandboxed evaluator for ESP32 microcontrollers that runs a safe subset of Python and Rust, enabling local execution of code generated by a tiny 0.45M-parameter language…
TetherIA launched the Aero Hand Open, a fully 3D-printed, open-source robotic hand priced at $314, designed for AI research and dexterous manipulation. The hand features 16 joints, 7 degrees of freedo…
A user reverse-engineered a FlexiSpot standing desk's proprietary protocol using an ESP32 microcontroller and Claude Code AI, enabling Home Assistant control. The same approach was used to hack a Plau…
A developer launched Traindeep.ai, a web application that generates trained neural network models for microcontrollers such as Raspberry Pi Pico and ESP32. The tool allows users to load a CSV file, dy…
Berry Scripting Language is now included in all Tasmota32 builds for ESP32 microcontrollers, offering an ultra-lightweight dynamically typed scripting language for embedded devices. The language suppo…
A developer built a 3.7 kB edge AI smoke detector in pure C, using a neural network that runs on ultra-low-power microcontrollers like the ESP32. The model monitors 12 environmental variables in paral…
A developer integrated a cloud-locked BanlanX SP542E LED controller into Home Assistant without new hardware by running a 150-line Python bridge on a Mac that translates Bluetooth commands to MQTT. Th…
Project that turns an ESP32 microcontroller into a speech-to-text device using an INMP441 microphone and an OLED display. Because the ESP32 lacks the processing power for local speech recognition, the…
