This is a RC car project is the transmitter and receiver modules for a Remote Control car, with speed control and continuous steering.

Circuit diagram for an AM radio antenna preamplifier that amplifiers the signal before it get to the AM receiver, thus making the AM radio signals stronger for better reception.

This is a complete AM radio for the standard broadcast band, most of which is on a single IC. Other components, such as coils and variable capacitor to make a finished radio are included. The IC is the RF Amp, detector and AGC circuitry. The IC's output d

Aircraft radio receiver circuit that receives aircraft radio signals in the 220-400 MHz band. This kit is small and simple to build, and it's a lot of fun to listen to aircrafts!

Training course of 56 pages is divided into 9 lessons; Audio Amplifier, AM Detector, AM IF, AM Amplifier, Amplifier, AM Mixer & Oscillator, FM Detector, 1st FM IF, 2nd FM IF, FM RF Stages. Superheterodyne receiver of standard AM (amplitude modulated) and

FM Radio Receiver Box Kit with Auto-Scan Function.

This 3-transistor radio receiver circuit is capable of receiving radio signals in the 5-15 MHz Shortwave band, and apparently costs on $10 to build.

Schematic, circuit design and comprehensive details about a SUPRX FM radio receiver, featuring high sensitivity and very low noise and distortion. [PDF]

RoboSapien is an advanced robot that can perform many different movements with the push of a remote control button.

An excellent Stereo FM Transmitter which operates through the USB port of essentially any computer. FCC Compliant!

This stereo pre-amplifier will allow you to get extra control over your audio.

The most powerful circuit we've seen that operates on such low voltage (just two AA cells). A range of 100 meters can be expected and, given a good antenna and FM receiver, 500 meters can be expected. An external power supply can be used up to 9 volts. Tr
