Reflections on the mains voltage

    Dopo il mio anno sabbatico dovuto a epidemia con relative complicazioni e diversi lutti ritorno a pubblicare È risaputo il fatto che se si deve andare negli Stati Uniti, After my sabbatical due to an epidemic with related complications and various griefs, I return to publishing It is well known that if you have to go to the United States

THE STRANGE CLOCK IN NTP

Dear ElectroFriends, I haven't seen new publications for some time .... I hope it's not the fault of some virus and I hope you are all in good health. I personally don't have (Luckily) problems, but from a social point of view it ...

Electronic power strip

CIABATTA ELETTRONICA Ovvero pilotare 5 prese a 220V tramite WIFI Eccomi con un nuovo progetto e questa volta non si tratta dell’ennesimo orologio più o meno digitale. Some time ago ravanando YouTube looking for some news ...

Current detection

. Methods for detecting the current in order to find the one that best suits the measurement. Shunt: the simplest method is through a Shunt that we can buy or do it yourself with thread with a very low value ...

Nyquist-Shannon theorem

. Comprensione dei sistemi campionati Il teorema di campionamento di Nyquist, or more precisely the Nyquist-Shannon theorem, it is a fundamental theoretical principle that governs the design of mixed signal electronic systems. Technology…

Dot clock, XP

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…
