Hehehehe  you guys are crazy, but i like it.

on with the show. It's good to see alot of people now experimenting

Hi Carl,

When you try this, take out the diode.  The diode isnt needed unless you want to de-modulate the received signal.  Plus these signal diodes can only handle a very very small current and will break if its too high.  You can try some in parallel instead.  But having a tuned circuit with an aerial will receive a signal, no need for diode unless you want to listen!  Plus with diode in you will not have nice AC to feedback, but DC pulses.




Dave.

Isn't that what we want in the control coil though? sharp DC pulses?

Hi Carl,

A DC signal will excit a tuned circuit, so I guess that can work.  But if you feed it back and back still contains the original energy.  I still cant see where any extra can come from?



Dave.

Dave I am thinking the magnet is providing the amplification. Remember what was said a few pages back regarding the magnet and the coils? Well I gotta try this to see if this will provide the minor amplification required to start the feedback loop.

Marco,

Here is the signal of your tuned circuit with two opposing magnets.

It is not the signal of a charge draining, or ringing off that was left in the capacitor.  It is random and spikey.  I do not think this can be from the left over charge ringing off?

Can you try it again?

@Carl, perhaps the magnet can do something here 


Dave.

dave, thow a diode in here (on the output to the scope) and lets see what the output looks like then

Guys, I'm not sure about everyone else but the website (or maybe this thread) is still giving me problems, maybe we should start a second part to this thread to take the load off the server, what do you think?
