Orologio a puntino Descrizione Come da una discussione di Oriolo20, forum member, I developed this project, if we want to call it that. In fact it is not really a complete project but only the proof of an experiment that wants ...

Experimental Class D audio amplifier

. I made a class D audio amplifier entirely with discrete components, although not the most recommended, the idea of ​​this project is purely educational to understand the operation of a class D amplifier ...

Simulated inductance

. I recently designed several variable power supplies to test tube amps, actually I designed more than one at the same time with different characteristics. They all have one component in common with the rotator. The shooter ...

Variable frequency audio generator

. This circuit was created to be used to test amplification stages. It produces both square and triangular wave outputs that rise from approx 80 a 730 Hertz in a repeated cycle of approx 6 seconds. Appropriate value substitutions…

Low resistance meter

  Create a circuit for the precise measurement of low resistances. You already have a DMM to measure resistance, but it can be used with resistances lower than 1Ω? And if so, these low resistive readings are reliable? This…
