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.
This article provides a guide on building a DIY high-end Bluetooth speaker in only 30 minutes using an ESP32 and simple hobbyist components. Using a LILYGO T-Display board, which supports the Bluetooth Classic protocol required for A2DP audio streaming, the project pairs with a MAX98357A module to act as a digital-to-analog converter and amplifier. The setup uses the I2S interface for audio transmission and can even display track information and connection status on the onboard TFT screen. It is an excellent, quick project for electronics enthusiasts looking to repurpose spare parts into a functional, polished audio device.
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.
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.
Firmware and software to run an ESP32-CAM module on your Flipper Zero device. Allows capturing images and streaming live video to the Flipper Zero.
A curated list of resources for the M5Stack Cardputer, a $30 credit-card sized mini computer based on the ESP32-S3. Includes specs, pre-installed apps, community apps, and resources.
It is a 4-inch touchscreen device designed for Meshtastic®, powered by dual MCUs, the ESP32 and RP2040, and supports Wi-Fi, BLE, and LoRa®. It is an open-source, powerful IoT development platform.
The T-Deck is a compact device with a 2.8-inch IPS LCD touch screen, integrated keyboard, trackball, microphone, and speaker, running on an ESP32-S3 dual-core processor. It supports various frequencies and includes a GPS module and battery in its Plus variant. It features a U.FL/IPEX antenna connector for LoRa and can be flashed using Espressif's firmware download mode.
The WoeMeter is a machine built for Severance Season 2 to measure Woe, one of the Kier Eagan's 'Four Tempers.' It was designed and fabricated in six weeks using materials like aluminum, 3D printed PETG, and repurposed components from a vintage Nagra audio tape recorder.
