IoT Projects

Accidental Antenna Design

To most engineers, antenna design is “one of those witchcrafts you either know how to do, or you just don’t”. Janne’s research lets a cluster of Nvidia B200 GPUs brute-force antenna designs for manufacturing, the results are pretty surprising. – somethingfromnothing

ePaper Camera

Snap lo-fi pictures and transmit them over WiFi to your ePaper photo frame!. – Adafruit Learning System

OpenClaw on Raspberry Pi

An experiment for giving an LLM agent full control over a Raspberry Pi and letting it interact with the physical world using peripherals such as a TFT display, sensors, and a USB camera. – Adafruit Learning System

Analog Clock with NTP Time

This project modifies an analog clock (the ones with hour and minute hands) to connect to a network time server, allowing it to display incredibly accurate time. – GitHub

Hacking the Adafruit IO Library

Our IoT Service, Adafruit IO, recently added a new API for grabbing air quality data from Open-Meteo (for international users) and AirNow (for US users). Danak hacks apart the CircuitPython library to add support for this new API. – Adafruit Learning System
