Homemade Tunnel Diode at Glenda Kurtz blog

Homemade Tunnel Diode. (see illustrations 3 for basic, 4 for a regen., and 5 for an oscillator.) Four years ago i made two transatlantic (ham) radio contacts (morse code) with a homemade transceiver, entirely built from diodes as the only active devices. A headset of any impedance can be used at audio frequencies to make adjustment easy. Tunnel diode works based on tunnel effect. What is a tunnel diode? This relaxation oscillator can be made to run at any frequency from audio to 12 mhz by changing the value of the inductance. This project may not be very practical but i find it to be a very exciting. Negative resistance relaxation oscillator from homemade tunnel diode. Leo esaki invented tunnel diode in august 1957. I believe there are only 1 or 2 companies in the states that make tunnel diodes anymore and this site explains how to make. The following image shows the symbol of a tunnel diode. The homemade tunnel diode can also work very well in a straight, conventional crystal radio receiver without regeneration—and i have included schematics for both types. When voltage value increases, current flow decreases. The tunnel diode shows negative resistance. This is an actual realization of some very old, and esoteric 1920's experiments, by.

This is an actual realization of some very old, and esoteric 1920's experiments, by. It is almost like making your own homemade transistor.
