3.7 VOLT BATTERY POWERS 56 WATTS

[gyulasun]

Ok, i just tested the new 5 volt-2.4 amp usb charger on the circuit as is.
It is drawing 150 milliamps at 5.25 volts or .788 watts, the brightness is ok, not at the level it was before,
so will have to make some alterations to the setup.
One thing that is interesting, the neon is still lighting up fairly bright across the transistor collector/emitter,
even using this 5 volt input.
I wonder if my diodes are ok, or since i have so many turns on my coil, maybe i am getting some
high voltage induction from the on phase of the input pulse, or i need to use a full wave bridge.

Yes, the neon when is lit (placed across collector-emitter) indicates the peak (voltage spike)
amplitudes are higher than the neon's trigger voltage hence it limits the spikes to that level. 
To utilize the higher than the neon trigger level spike amplitudes and steer them also to the puffer capacitor,
at least a 500-600V rated switching device is needed and then you can omit the neon.
IF your neon has a trigger level of say anywhere between 70-100 V, then you could try two of them in series
and see whether they are still lit. Their trigger levels add so the two of them are still able to protect your
present 230 V  rated transistor.
Of course you may use a full wave bridge made from the fast MUR or other fast switching diodes.
From the 5V input supply your base resistor (220 Ohm) may need another value, perhaps a 1 kOhm
trimmer potmeter with a series 100 Ohm would be good to use and vary (like in magnetman's schema).

Hi all, Hi gyula, thanks for the helpful information.
Yesterday, i tried a bigger capacitor, that did not turn off the neon, then tried a full wave bridge, that did not turn off neon either.
Your 2 neon in series worked, they are no longer lighting.
Only problem now is, the 4 gutted led bulbs brightness at the 5.25 volt input, is not sufficient.
I will have to make another bifilar coil using less turns.

Hi,

Well, there are many makes of the LED assemblies, and it is surely hard to find the ones having the most efficient inner drive circuits with or without.  Magnetman wrote about his experiences.
I assume you mean the gutted LED bulbs brightness was not as sufficient by "default" as the Eco types were?

Has anyone made my circuit EXACTLY as I have posted  here.  All was posted as OPEN SOURCE information.  Presently using a 5 volt USB wall adapter I show 5.7845 watts powering  8 seven watt 12 volt bulbs. That's 56 watts and all 8 bulbs burn brightly.   I would like to know if anyone is following my specs exactly as posted.

Hi gyula, the gutted led bulbs i'm using now are fine, it's just when using the 5 volt input with this coil, is not sufficient.
So i made made a new coil earlier today, will be testing soon.
Hi magnetman, i do not have any 12 volt bulbs to test at the moment, i have a ton of 120 volt led bulbs though.
Plus the fact i could not get the SCR to fire properly, though since i do not know what frequency or anything about how yours is functioning, what are we to compare it with.
The oscillator itself should not matter, unless yours is operating with super efficiency.
So for now, I'm working on at least getting an oscillator running on the 5 volt input and getting good light output, i can always try the SCR again or get the one you are using, maybe that's what is needed.
