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 ...

48Vdc Phantom power supply starting from 12Vac

. Hello everyone. Here is the wiring diagram, the file for the LT Spice simulator and the photos of a power supply suitable for condenser microphones and DI boxes (Direct Iniection box), all used in the music field. The cicuito ...

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…

TRIODES ELECTRONIC

TRIODI ELETTRONICI Questo articolo sarà dedicato ad un altro tipo di tubo elettronico, the TRIODE, that can be compared to a faucet, since it allows to vary the current flowing through it, precisely like a tap makes it possible to adjust ...

Metal simple and powerful detector

Metal detector semplice e potente Mia figlia si è messa in testa di voler usare un metal detector per la ricerca di reperti antichi, where I live there are many areas to explore, the possibility of discovery are very low but, with a little…

VCO Analog

. VCO Analogici Leggendo una news che riguarda il SuperBooth di Berlino, there was a trend during the edition 2018, the return to physical synthesizers. Hardware, to speak, that is light years away from software that now reign ...

New standard for Underwater Communications

Nuovo protocollo standard della NATO per le comunicazioni subacquee JANUS potrebbe veramente rivoluzionare l'industria subacquea con dispositivi in grado di comunicare e condividere informazioni che non sono mai una cosa negativa (recalls how ...

Simple peak limiter

Semplice limitatore di picco Ci sono alcune situazioni, in which it requires an amplifier which imposes limitations on the output signal. What I mean is the following: for small input signals, the gain is a certain value. ...

Limiter average audio

Limitatore valore medio audio Questo limitazione audio non include alcun Mosfet o Jfet o amplificatore a transconduttanza difficile da comprendere e utilizzare, I'm not the author of this configuration but, place here this circuit ...

WITHOUT RECTIFIER DIODES

RADDRIZZATORE SENZA DIODI Ecco un raddrizzatore senza diodi e senza soglia molto semplice. in the scheme, a single operational amplifier such as the LM358 and 5 resistors create a full-wave rectifier. The output voltage is 1/3 of the…
