@madamerotten ------The circuit diagram is correct. The LED is positioned correctly the way that it is. This is similar to an Armstrong" but I prefer the term "tickler oscillator". Notice that there is no capacitor in this circuit. It is kind of a runaway frequency design and would not be of much use to most people. Thanks for your comment and interest.
@Lidmotor I'll have to try this to see what's going on. If the white LED is turning on, then the base-emitter junction must be reverse-biased at least part of the time during a cycle. This is very interesting.
@harpbloke ----Hi. The first time that I did Jonny's "Pan Oscillator" I used a 12v car ignition coil. When that worked I pulled a tiny trigger coil out of a disposable flash camera and that worked. After that I went ahead and ordered some 10K trigger coils from a company here called Mouserdotcom. They only cost about $3 US and worked the best. You can use a 4K trigger coil and it will also work.
@jonnydavro --- Thanks. This was a good idea when you came up with it and it is STILL a good idea. I would like to see some of the new people dig into this circuit more and maybe make even better.
@andrewg85 -----Several of us did get this to work using a car ignition coil. The small trigger coils you can get at most electronics stores or even out of a disposable flash camera. You could wind your own but you would need many many turns on the secondary.
@Lidmotor --- Sweet! Have you tried a higher power transistor? The 2SC2238 (RS Australia part# 197-9862) still has the 100MHz bandwidth the MPSA06 transistor has, but a higher power handling. The 2SC2238Y transistor has a higher gain than the 2SC2238. It might make for an upscaling of this board!
Okay, layman question : have you ruled out that these kinda circuits are 'just' picking up man-made waves instead of sumthin natural ? I mean, I luv these experiments, but that keeps nagging in the back of my mind.
@JavaLessons ------The technical discussions on how these circuits work goes on and on. Even the experts argue about it. The ones that I have built are high frequency high voltage booster circuits. When you do that some very interesting things happen envolving capacitance.
@jackscholze -----Aloha Jack. We worked on this last year quite alot and so I thought that I might have another look at it. It is an easy thing to put together and you get immediate results.
@jiffycoil -----Maybe you can build one of these and tell us what you think. You may take one look at the thing running and say: "Oh yeah but if you just do this or that to it it's going run much better." Right now the Slayer Exciter out perfoms this.
I think if you add 2 more diodes to the "indicator LED" string, it will save the transistor. Also, the amp draw should reduce if you have the output going to a rather large mass, that is near but not touching earthground.
Anyhoo, nice setup. Much more pretty then the one I did.
@CosmicGnarler -----We worked alot on this last December remember. Amigo posted some great spectrum shots of it . I will try your output to a mass idea to reduce the amp draw. Right now the way I have it, the light/watt ratio isn't bad.
@Lidmotor Ya thats why I was slightly surprised to see a revisit of one of my old favorites. That crazy video of mine showing the 0 amp draw as I hooked more lights on... Dang those meters can get fooled sometimes.
Your videos are always fun to watch. Each time you do something, it seems 5 other people are instantly busy at work making it better or changing it somehow. You are like an alt. E captain! You and Johnny and Slayer and Jiffy and etc etc..
@GBluer ----I got the idea about doing this after spending so much time with your circuit. This circuit does not perform as well as your's but it is in a very small package.
I think you drew your LED upside down. This oscillator topology is called an "Armstrong" oscillator.

great experiment.
do you know where to recycle that type of coil from?
thanks

@Lidmotor many thanks. i kept breaking the yellow flash camera coils, ha.

Nice feedback idea.
I add an antenna conection to the trigger out and the base raise the flyback
watch?v=HIxhfx4BdM4 "pan oscillator with 42 feet high antena "

Hi Lidmotor.Great to see you rework the pan oscilator and I like the compactness of it without the pans .Nicly done.Jonny

This is very nice! I made this circuit, it works to the same principle as the led joule theif!

Looks interesting and worth a replication!
How did you wind the coils?
Will an off the shelf car ignition coil do the job?
