Build a crystal oscillator from schematic thru prototype construction and testing - DIY

Interesting test board.

This video takes you through the process of building a circuit from a schematic, including circuit board preparation, soldering components using Manhattan style construction and then testing it. It uses a buffered Colpitts Crystal oscillator as the example.

Crystal oscillators was well known snce several decades ago. Difficult nowadays to find crystals in the audio range. I read about a large 2KHz in the MIT book. But most of them are 100KHz or more, excepting 32768 KHz for motherboards and clocks, but I read they are tunning forks, not true crystals.

Interesting test board.

More or less like dead bug construction on ground plane.
