Crystal radio from ignition coil.

[Lightium]

Look at my contraption. It's supposed to be a self-powered active crystal radio.

There's no audio. Your speaker won't do a lot with a 680kHz drive.

 

[Lightium]

I have to adapt some audio recording for the simulation to test it still.

Sorry, but that is not going to work for multiple reasons. Among other things, neither transistor has proper bias and a diode connected directly to a cap cannot do anything useful.

If you are using batteries anyway, why not build a conventional radio? There are thousands of good, practical designs around.

 

[Lightium]

Don't be sorry, it's just an unfinished idea I am trying to bring to reality.

Perhaps a MOSFET at the coil will improve signal reception and quality. Where's the antenna?
