A Variable Capacitor Made From Junk

This variable capacitor comes directly from a piece of 1.5 mm thick aluminum sheet. Instead of fancy CNC machines, power tools, or even a pair of tin snips, [Jezan] cut the rotors and stators for ...

Crystal Radio Part 2

We now had a functional variable capacitor. Sliding the outer roll over the inner roll varies the capacitance, and it was that simple. However, it''s far from user-friendly in this configuration. We set out to improve this, starting with a mounting for the capacitor. We cut a strip of foam-core board 5cm wide and as long as the A3 sheet would ...
