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.
Monitor air quality with the Fermion BMV080, the world's smallest fanless PM2.5 sensor.
This ultra-compact breakout board utilizes innovative laser-based light scattering and a fanless measurement principle to deliver laboratory-grade precision in a footprint of just 24×20mm.
Capable of simultaneously measuring PM1, PM2.5, and PM10 mass concentrations with an accuracy of ±10μg/m³, the device operates with an ultra-low current consumption of 6μA in sleep mode.
It's perfect for space-constrained applications, ranging from portable air monitors and smart home thermostats to battery-powered IoT nodes.
