As a free flying paragliding pilot, I have finally built my own simple but effective instrument that plays beep-beep during climb and so on.

Make your own motor driver shield PCB for an Arduino Pro Mini using an Arduino Pro Mini.

A cheap beam break sensor utilising a reflector panel instead of a transmitter / receiver setup. Capable of handling long distances.

Trying to build a cheap Arduino data glasses for everybody. It's working, and now it can even help to avoid accidents.

Another plant watering system, now with a light sensor, 4 LEDs, silent pumps, and memory.

Automatic window roller blinds that can be controlled wirelessly by a small remote, web interface or RESTful API.

How to build an all band receiver with SSB support using the "Si4735 Arduino Library."

Robotics project that aims to improve rover control through the use of radio frequency and the interaction of rover movement.

A Google Assistant compatible box for kids (from 2 years old) to control lights and other devices in their room.

How to turn your RC Car into a Bluetooth controlled RC Car.

Automated chicken coop: automatic water and feed dispenser, IR based egg counter and notifier.

We all love playing with RC toy cars. In this mini project let's create an RC toy car using a bunch of wheels, motors, Arduino & nRF24L01.

Smartwatch that shows notifications from an iPhone and automatically synchronize the time.

Life Band monitors the health conditions of elderly up to date and provide immediate medical assistance if necessary.

A touchscreen control panel for home IOT devices. Arduino, Raspberry Pi, RFM69, mqtt and more.

In this project, I will show you how we can use a 3€ IR distance sensor to build a proper DIY tachometer that functions properly.

This project is about an Arduino Library to control the BK1086 and BK1088 devices. It was based on "BK1086/88E BROADCAST AM/FM/SW/LW RADIO R
