While we’ve come a long way in terms of opening up the world of radio control to open source software, a good deal of the hardware itself is still closed up.

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 ...

We may not to able to make a mobile phone system but our very own radio station with a transmitter and receiver might just be possible. What is a transmitter? Radio can be incredibly simple.

Remote control allows the location of the control point (typically the main studio) away from the transmitter site. The rules state that “The remote control system must provide sufficient transmission ...

These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

AM radios are relatively simple devices, and building one is a good way to start exploring the world of radio communications. [GreatScott] does exactly this in the video after the break, building b… ...

Cell phone coverage can be spotty. Enter Pocket FM, a portable FM transmitter the size of a shoebox that starts working as soon as it’s connected to a small antenna, a power source, and an audio ...
