RC Pulse Generator

The purpose of the project is to measure resistance values and generate R/C style pulses suitable for driving servos or testing R/C controlled robots without the transmitter as it uses an Atmel AT90S2313 AVR processor.

FM Receiver with a Single Transistor

This project contains a very unique one transistor FM receiver  accompanied by homemade air-core coils and a homemade fixed capacitor.

Building the Simplest TV Transmitter

The project aims to create the simplest TV transmitter from the simples FM transmitter project by just changing the input from the audio to the video and checking the TV signal.

SSB Transceiver Known as Five by Twenty

The project consists of 5 vacuum tubes without ICs or transistors for making a true SSB QRP transceiver for 20m Ham band.

Cell Phone Used for Remotely Starting a Car
