Joulethief SEC exciter and variants

[xee2]

@ Seth

All of the manufacturers seem to use different pin numbers for their flybacks. So the pins to use on your flyback will probably not be the same as on mine. My L1 coil is 0.8 ohms and my L2 coil is 1.6 ohms. You may also need to reverse the leads on the L1 coil to make it work. Finding the correct pins to use is the hardest part of using flyback transformers. It is easy to find the other end of the HV output coil, but the others are not so easy. Sometimes L1 and L2 are part of the same coil (center tap) and sometimes they are not.

I suggest using a neon bulb across the output coil and working with a 1.5 volt battery so that you do not damage the flyback before you find the correct pins. If your connections are correct the neon will light from the 1.5 volt battery (my flyback will light a fluorescent tube from a 1.5 volt battery).

ultra low power exciter

Thanks Jonny.

Sorry for the last video.
This one the lighting is a little better.

The exciter is running off a AA rechargeable battery using 50 to 120 uA.

Good job! Let us know how you did it.
I have been exploring the realm of ultra low power circuits also and this is great news to me. It means that we might be able to get an exciter to work off solar cells and just ambient indoor solar energy.
My efforts are now in replicating a circuit that I found in a toy called the "Solar Powered Lucky Cat". That little device will start running automatically as soon as it gets light in morning. The tiny solar cell (panel) measures 1/2" x 1 3/8". There are a number of other devices on the market that use a similar low energy driver circuit to make motion.
Dr. Stiffler has mentioned on his thread that he is also testing a transistor that will trigger and very low power.

Thanks Xee and Kooler - ive found the magic pins!!!! Only problem i have is arcing all over the flyback pins, but its certainly working now - here is my first prototype of the jacobs ladder:

The alan keys need to be replaced with something better, and the circuit needs tinkering. Nonetheless, great fun.

@ Seth.

Great start. The diode and capacitor should increase your output voltage for the same input voltage. I just got some new flybacks, so now I get to be frustrated trying to figure out what pins to use on them. I sure wish they put diagrams on the coils.

[seth]

Still cant find a cap with low microfarads, but the diode works fine. This flyback transistor circuit will easily power a little magnet/neon light/croc clip motor. Ive just tried it - spins really fast. I connected output pin 8 to a sheet of al foil under some wood, and connected the rubber sucker to a neon light suspended frm a croc clip via a tiny magnet. Works a charm if you fancy some motor experiments.

Heres an improved version of the jacobs ladder

Thank you very much for postinig this circuit. This is the one that I have been trying to replicate for weeks.. I have that exact blue "waving arm" device and could not figure out the circuit that it uses. There are a number of other circuits used on these type devices but THAT one is the one I was looking for. The circuit that is in the "Solar Powered Waving Lucky Cat" is a little different I think but the principle is the same.

You did not put a value on the C3 capacitor in the circuit diagram. Is it 4.7uf like C2 or different?

Solarbotics sells a great little 1" pancake driver coil for $2.50 that will work on this circuit if anyone else is interested in building one of these. I bought a few of them and may try to make a subminiature "Jiffycoil Pancake Exciter" using one.

Here is a link to Solarbotics site. They are located in Canada and sell a bunch of neat stuff.

@totoalas
Thanks. I would have gotten that cap value wrong.

Thanks Lidmotor.

It was nothing special I was just surprised it would run at that low a current.

The transmitter tower has a bigger L2 coil around 16 turns with a variable capacitors across the L2 coil.
The receiver tower had an AV plug going to a steel bowl.

The receiver tower seemed to help keep the current intake down.
When the tower was moved the current intake would go back up.

[slayer007]

In this video I replaced the indicator led with a second L2 coil and tower.
The second tower or L1 coil is not connected to anything.

I also have two other coils running to an s type gate.With an AV plug running back to a cap thats running right back to the source battery.

@slayer007

Youtube is acting up! I cant send messages or post. HM..

This is what I wanted to say.

"Just keep poppin' them coils all over your circuit and it seems to work. Great idea to put another L2 where you did... That spot was pretty much wasted energy, instead of frying a transistor or lighting one led, it now works a whole tower!

Can you make a video where you light up your whole room from a 1AA battery? Thats going to take alot of LEDs but I think around 200 should be easy for your setup.

Does the Sgate help?"

Thanks CosmicFarmer

Adding the second L2 coil and tower made a big difference in the main L1 coil output.
The field around the second tower is very weak.But it sure helps the main L1 coils output.

I'm really not sure if the Sgates helping or not yet.But It's been over 12 hours now and the light is still going very bright.

Later today I'll make a new video showing the coil specs and the circuit I'm using.

[slayer007]

My last test I let the Exciter run for 15 hours before turning it off.
The voltage in the battery was 1.1v after running 15 hours and lighting the 39 led's.

For this test I removed the Sgate and added an AV plug to the bottom of the second tower.
