Hi magnetman, thanks for sharing the pics.
Just to verify, the led bulbs are 12 volt DC input correct.
So no problems with the capacitor dump voltage being so high, the 12 volt led bulbs are not being damaged by this.
Maybe because the capacitor capacitance value being so low, is why it's not frying the leds inside the bulb.

This is a HYBRID circuit I made using a lot of thoughts from many different people.  Jonny Davro thought of using the automobile coil to limit hi current to the 35C transistor.   I thought to use this Bedini style circuit with many different parts and a different plastic coated coil wire - my choices.  The low current transistor 35C powers the hi current coil part of the circuit and the hi frequency, voltage, and current BACK EMF (radiant energy??) is dumped into the bridge rectifier and capacitor.

This is where this becomes interesting:    Since I figured the radiant energy from the coil needs to be used some place I found a article (now deleted) from the internet about how to gather and use radiant energy using an antenna system.  It was posted by Andrew Munsey.   So I directed the cap to dump is collected radiant energy into the SCR and see what happens.  I burned up a brand new watt meter doing this only to find the circuit worked with the shorted watt meter in place????  I substituted A section of wire in its place and the circuit has worked flawlessly to this date.
I even had it working using a very small 12 volt 27A cell.     It also will work with 24 volts DC but take care unless you burn up your 12 volt bulbs,

   Correct  - 12 volt input.

3100 mAh 18650 battery can give 20A at 3.7 volts easily, which corresponds 20 x 3.7 = 74 watts of power

Hi magnetman,

Please check the wiring connection of the thyristor pins in your schematic versus your setup
(you uploaded the schematic in previous page, Reply #10) because I think there is a drawing error.

The K pin (Cathode) ought to go to the negative rail (I mean the emitter pin of the TIP35C transistor
as negative rail) and the center pin A (Anode) of the thyristor ought to go the negative end of capacitor C1
(which is on the left hand side of C1 symbol). I think this would be the correct wiring.
The Glimm lamp is okay between A and G  (G=Gate).
(In your schematic, the K pin goes to the negative end of the capacitor C1 and the A pin goes directly
to the negative rail.)

I edited your drawing to show how I mean.  Here is a data sheet on the thyristor:

If you disagree with my schematic modification, please tell.

EDIT   Thanks to member citfta's explanation I deleted my drawing because it was not a correct modification.

The black dots on the schematic are where connections are made.  The bent line you pointed out is a jumper.
no connection at midpoint is made.

Hi Gyula,

I am afraid I have to disagree with your correction.  His schematic seems to be correct to me.  If you consider the output circuit to be separate from the input makes it easier to see what is happening with the SCR.  The input and output are sharing the same negative rail but they don't have to for the circuit to work.  In your mind break the negative rail just to the right of the connection of the neon that goes to diode D2.  Now look at the SCR circuit.  You can now see that the SCR has to have the cathode connected to the negative side of  C1 or it could not turn on.  Also as you have corrected it there is no way for a positive signal to get to the gate to turn on the SCR.

Respectfully,
Carroll

Hi all, thanks for the clarification magnetman.
I will be picking up an SCR soon to build this device and couple other parts.
One more thing magnetman, is the neon lighting up fairly constantly, if you can even see it light up that is.
I guess it is, or you would probably see the led bulbs increase and decrease in brightness.
Are the led bulbs lighted in a stable way or can you detect any fluctuations.
Anyway, i will be building this.
peace love light

  The neon bulbs light up at different intervals depending on what you are experimenting with. But most of the time you cant see them lit.  As far as the 8 led bulbs go they seem to keep good brightness constant at least to my eyes when powered by 1.2 AH 12 volt battery or wall wart.  8 bulbs will light up dimmer when a power source with little current is used.  Say you powered it with a very small 27A - 12 volt battery or same with 5 volts out of a USB  battery charger. I have been experimenting with this circuit now for 3 years and it still keeps on working like the battery bunny on TV

Its the most interesting circuit I have ever put together that keeps you guessing what its capable of doing

Hi Carroll,

Yes, you are correct. Unfortunately, in my mind I mixed up the position of the thyristor switch as if
it would be in series with the load  while in magnetman's circuit it is in series with capacitor C1 which
is the voltage source for the load.

I deleted my incorrect drawing from my post.

Thank you.

Gyula

Hi Gyula,

You are welcome.  I made a similar mistake a couple of weeks ago.  I had a circuit all designed on paper.  It was only after I started putting parts together on a piece of perboard that I realized my circuit wouldn't work like I wanted it too.  So it was back to the drawing board again. :-[   I guess most of us do that from time to time.

Take care,
Carroll
