If you’re looking for a simple way to make an RF transmitter, check out [Tomasz]’s Morse code transmitter. His design uses nothing more than a microcontroller and a 16MHz crystal to transmit CW Morse ...

The wireless transmission is being demonstrated by the simple circuit which can send Morse Code signals over distances of a few meters to any AM radio. The Morse Code signal is considered as a ...

In this image from the MRHS website, Paul Zell sends the last commercial Morse messages at KFS/KPH (or so it was thought). Several historic Morse Code stations will be on the air again Sunday evening ...

This could work for any hollow figurine you have collecting dust on your shelves, but due to Android’s open-source nature a little robot is the obvious choice for DIY hackery. The full tutorial is on ...

World's Most Power-Efficient, Fully Integrated Transmitter Slashes Battery Power Consumption by 75%, Setting a New Benchmark for IoT and Edge Devices The whitepaper details the breakthrough ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...
