Emergency Egg Locator Beacon (EELB)
This project was inspired by a circuit that a friend, Simon Field, showcased. He built a simple transmitter circuit using a 1 MHz "can" oscillator and a serial connector. In his circuit, he utilized a computer to turn the transmitter...
REGENERATIVE_SHORTWAVE_RECEIVER
The receiver consists of multiple subassemblies, including an active antenna, an amplifier featuring regeneration control and band-switching circuitry, an AM detector, a power amplifier, and an output device such as an internal speaker, external speaker, or headphones. Additionally, it is...
televition transmitter
The camera is oriented to look out the side of the rocket during launch and downward during descent on the parachute. An optional external mirror can be added to enable the camera to look down during lift-off. The transmitter antenna,...
Test Transmitter
The Test Transmitter (A3020) is a combination of three circuits designed to test the Subcutaneous Transmitter (A3019) and to analyze surface acoustic wave (SAW) voltage-controlled oscillators (VCOs). The A3020 incorporates the complete A3019 circuit in its central section, which closely...
