What happens if you remove the clip lead which is loading the one inductor/LED and just let the inductors and Led be supported by e,g, a nylon fishing line to the LED?
If i let the circuit just lay on my bench,i have to raise the frequency to get the LED to light. If i hold it up by hand via one of the exposed wires,i have to lower the frequency to get the LED to light.
As we know,we are simply decreasing or increasing the size of the capacitance value,where the lower value would be just having the wire of the circuit it self as 1 plate(the other being ground of course),which would require a higher frequency,or having the larger plate,which would be myself holding the device,which would increase capacitance value,thus lowering the resonant frequency.
BTW, I suspect by now you have solved the mystery of the lighting neon from your other video. Have you?
Well kind of,although im still trying to understand as to how it causes this effect.
I can reproduce the effect,but as yet,do not fully understand as to how it can be this way--i.e,how current can flow in the circuit the way it was hooked up
We'll come back to that one day,as it is quite interesting.
Bigger fish to fry ATM.
If you salvage old CRT monitors or TV's for parts as I do, you will sometimes find on the small board on the neck of the CRT glass tubes that look exactly like a neon, but there is no neon gas in them, they are just spark gaps. Also things that look like small glass diodes will actually be tiny spark gaps. Typically though the protection is done with a plastic device with electrodes precisely spaced and a plastic cover over the body.
I use to salvage them all the time. The loops of copper wire around the monitor it self was ideal for the SSG pulse motors.
But they are getting harder to come across over here now.
There is a wealth of interesting components to be had by salvaging old CRT monitors, TV's laser printers etc. I use a heat gun to remove parts from the PCB quickly.
Yep,that is how i use to do it as well
I now have a small blower nozzle that attaches to my soldering iron,driven from my compressor.
now i just get the solder to melting point,and hit the air nozzle trigger,and it blows the solder right out to a clean hole.
