Once again doing a project that deals with stepper motors? Once again losing track of which cables go where and who does what and what was the neighbor's name? Gotchu covered with a controller I designed for one of my robotics projects, only to realize... why not use it elsewhere as well! (does not remind you of your neighbor's name, however)

Autonomous LoRaWAN node easily connectible via TTN/Helium networks, supporting downlinks with sleep current below 1mA. LaRaWAN node based on Seeed Studio' Wia-E5 module (based STM32WLE), so no additional transceiver needed - the main MCU and LoRa PHY already inside - suitable air quality monitoring, garden, intelligent home, automatization... You may connect load remotely by downlinks - via AO3400A transistor (on board). Optimized for Sensirion SEN54 sensor. MPPT and Li-Ion battery charger for power from 5V++ cheap solar panels. 10+ years of autonomic work with cheap 2W solar panel and standard 1850 Li-Ion battery expected.

The Silent Wind is a wearable system that visualizes the invisible presence of wind through subtle light and movement, using five microcontrollers and inspired by traditional Japanese aesthetics.

A versatile Smart Desk Assistant using an ESP32 microcontroller that responds to button presses and voice commands, displays temperature & humidity on an OLED screen, and provides LED, buzzer, and optional vibration alerts. Perfect for intermediate Arduino learners looking to explore sensors, I2C communication, PWM, and basic IoT concepts.

A Raspberry Pi Zero gadget that turns your GitHub commit history into a glowing desk display as well as a self-hosted software hub.

This is a modern digital interpretation of a traditional barograph that displays real-time atmospheric pressure trends over a 24-hour period using a high-precision BME280 sensor and ESP32 microcontroller.

Open-source 3D printer project with CAD models and build documentation.
