Using an Arduino and Python script for testing simple logic I.C.s like 74xx TTL

Hands-free access. Just say the code out loud and the lock opens. Without Internet.

Project #12: Robotics - MOSFET - Mk28

A minimal, foldable print in place case / housing / sleeve for the Raspberry Pi Zero 2 with live hinges (with cooling)

A ready-to-use weather station. Quick setup: flash the prebuilt firmware and start testing in under a minute, no coding required. Open-source and customizable for your own weather-based projects. Firmware and source code available on GitHub.

This Arduino project is very simple to make and has a huge practical application.

eBUS Adapter Stick C6 is a reduced size version of previous highly demanded eBUS Adapter Shields and provides an interface to a 2-wire eBUS with galvanic isolation for enabling communication with an eBUS enabled heating, ventilation or solar system. With a size of 42 x 16 mm it is way smaller than the previous Shield versions, but still supports an USR-ES1 module being plugged onto it for having Ethernet access. Even better, with the upcoming firmware version for the ESP32-C6, it automatically scans the heating components and makes all data available via MQTT to e.g. Home Assistant with auto discovery of entities.
