You're too much. I think I will count to 6000 tonight while I think about your idea. lol

@marco

I made a relay pulser and it is buzzing like hell, but the voltage I am trying to send to the coil is not getting there. My meter says O volts dc when put on the coil.

Is it because I am pulsing too fast?

Here is a schematic I have drawn to show my connections.

Any comments.

hi
Doing so mechanically has limitations, we do not want that.
Probably the "on" time of your switch is not long enough.
you could also try to wrap a little coil around a glass reed switch but personally i think this also has mechanical limitations.
Then we can think of a hall sensor and a coil plus transistor in a similair setup, there will be no moving parts so the frequency can be much higher.

Last but not least, you could try what i call a "optical tank", this technique is used in switching power supply's and cathode ray tube modulation.
The phototransistors i am using are capable of going up to 1 Mhz in the Ir light range.

Furthermore, the idea of using amplified light to perform ANY useful
purpose or provide any gain to.....

1x 7905
3x irf840
1x 74hc125n
3x pot's (use variable at first,fixed values later)
3x caps (use variable at first,fixed values later)
3x cny17-2

Hello all,

@Macedonia CD

a picture is worth 1000 words. A drawing or maybe a video would be fine. Show us what youre talking about.

If that is one of those little TTL relays there is a transition time between break and make on the C form contact. The normally open side may not be making at all.

You could try getting your output from the relay coil leads but you will have more on time than off time. Things could get hot. Put a small cap across the relay coil then a pot between the relay coil and the normally closed contact. Vary the pot to adjust the speed.

The relay won't last very long but probably longer than am SM video 
That little relay coil will put out some pretty fast flyback.

MAC has a good point.

If the collector is a "circular resonator" it will ring hundreds of times from one kick.

In SM TPU letters, he talks about many small kicks combining into big kicks.  He never says that the control coils are creating kicks - like with electromagnetic induction.  The collector is exposed to a "change" which results in a small surge of current manifesting in it.

You're standing on the plate of a huge capacitor - lightning strikes, secondary magnetic field - all electrostatic phenomenon...
