Joule Ringer!

I can't get Xee2's transformer circuit to light any of the flourescent bulbs my modified flash ciruits illuminate. I tied a 1k pot into the 3.3 cap tank, and found a peak resonance where my twin 120 volt LED'S reached maximum brilliance. Output reads 6.5 volts a.c. at mid range.

try adding Laser's diode :-)

Diode.

@minoly,

Where would you position the "Laser diode", between the capacitor electrodes, or between the transistor base and pot?

The circuit I posted only puts out about 200 volts. CFL normally requires at least 400 volts.

@ the base of the transistor between the (cap/resistor) and the base pointing to the base.

I'm sure I muffed that up...

French version

Just adding some info.

Hi guys, here is a kind of simular french version, including a tutorial.

Wow even though I don't understand very many words of French, that looks extremely interesting!

My French is bad too, it could be just What it say it is: A simple inverter ;-)

The question is how long the battery lasts.

[soundiceuk]

After studying the circuit diagram for a little while.

Isn't the inverter producing 230 volt ac but at a much higher frequency.

All the electrical equipment works because the voltage is 230 volts a/c.

It doesn't matter that the frequency is much higher thats why it doesn't drain the battery easily.

Am I correct or not?

Please can you tell us what the frequency and current draw of this circuit is on load and no load?

Cheers

Flip flop circuit on steroids

Just adding some info.

I like this circuit. It is a simple flip flop oscillator triggering mosfets that turn the power on and off to the primary. Guys we can have some fun with this one. With the correct choice of components we could probably get this to do some amazing things. This is another one of those really old circuits that can be looked at again with fresh eyes.

It looks like, by the components he's using it would be running at around 96hz. Not sure how that would effect 50/60hz appliances over time - some don't respond well, others don't care.

Similar to the Royer circuit that's used in the small inverters, also being used for driving flybacks, flouresent tube drivers and small tesla coils. It is a slick little circuit with many possibilities - a dual joule thief circuit in it's basic arrangement.

Xee2 circuit.

I rewired Xee2's transformer circuit, with a switchng diode from the 1k pot capacitor junction to the transistor base, this time a Motorola 13007. The luminosity increased with lowered resistance untill I reached 160 Ohms, at which point the transformer began to ring audibly, but not annoyingly, and the illumination reached peak brightness. I'm running two 120 volt LEDS in parallel. These results have me elated! I plan to buy an accurate amp meter and measure input with additional bulbs. The addition of the second bulb has no noticable effect on the first one. Lasersaber gangs his ringer bulbs up to a pretty high number. Maybe they run on "reactive power"? This should make a good video!

Interesting. When I added a diode in series with the base the light output decreased slightly. It is good to have multiple testers.

P.S> It looks like traditional bipolar oscillator to me..

Transistor diode.

@Xee2,

Is the base diode a Schottky type fast switching diode in the 914 series? Another question is; Does your transformer ring? I think the resistence value would have to change after adding a diode to the transistor base. A 1k pot or trimmer, like I'm using would allow one to alter the tank oscillation frequency to regain the former brightness. The diode prevents feedback interference from reaching and disturbing the base R C tank oscillation integrity. The transformer's either ringing or it's not. There's only one full brightness. I'm running 12 volts into a 3.3uf ceramic capacitor wired across the legs of a 1k variable resistor. The "Ring is the Thing"!

The diode is there to protect the circuit and improve efficiency, not increase brightnessl A low range variable pot in place of a fixed resistor, would permit tuneing to peak resonance to allow for a diode or additional bulbs.
