fuji arcing

I've ran the fuji on 65V 8000uF with to-220 size transistor. It does start to arc after a while but doesn't arc between layers, only from hv pin to base coil pin. So you could probably coat pins with epoxy or oil bath it.

@All

I am almost ready to post the DIY videos on how to build a joule ringer including the transformer.

I have also discovered that the Joule Ringer will run a lit CFL for a couple seconds after the power is disconnected, even with no electrolytic capacitor in the circuit. It just runs on the coils alone for a few seconds. I will also show this effect in my next videos. Here is the circuit that I use when running with no capacitor.

fuji or other disposable camera currently unavailable in my location. I'm trying to use other transformer but found poor result. good quality insulated wire also unavailable so i can't make a transformer like fuji. I'm waiting if someone give alternative transformer design and hope Mr. LaserSaber's next video will be more helpful.

Where are you

Do not know where you are, but for those of you in Canada, AA Fuji's are still
available. The "President's Choice" disposable is the old Fuji AA circuit. Also, I
was at Wal Mart yesterday and they had 2 pak "Children's Miracle Network"
Fuji disposables on sale for $10.00. These were also the old Fuji AA circuits.
Thanks to wackyO I have made a successful Fuji/CFL replication with these.
No fried transistors or circuits this time. Hope to make a better video on the
correct procedure to do this. Since any I have seen are not very clear, and I
have seen about 10 of them if not more. The result of these unclear videos
contributed to my problems in the past with these circuits.

I'm from BANGLADESH, Asia. Film & Flm-camera is almost unavailable in my location. But "Mosquito Killer Bat"/ fly zapper is available. I experimented but zapper ckt is >9V, I need low voltage transformer like fuji AA.
Thanks for your cooperation.

Trade

Wish we could trade. Light output with CFL and Fuji is low but not bad with
an unmodified 3.5 watt led 110 bulb, Never saw this before, Lasersaber and
LIdmotor were using what appeared to be 1 watt bulbs.

self wound joule ringer

I built a self wound joule ringer on a 2"x2" E-core. I used 24 gauge primary ~6 turns and 36 gauge secondary ~1200 turns (plus the additional turns on the secondary). The transformer worked well, but drew 10x the amperage compared to the fuji transformers. I didn't mind, since I wanted to do some experiments with a more robust transformer, but the increased current caused the whole thing to heat up pretty quick and burn up when I was using 24 volts as the input.

Anyone have any thoughts on how to make a larger, more efficient joule ringer transformer? The first coil took a lot of work to assemble, so if I do it again, I want to be fairly certain that I'm making improvements. I've thought about using thinner wire on the secondary, but I don't know enough about transformer theory to be sure that would help. Any insight would be appreciated!

funny. I had the same thing happen to me. Toasty. I've had some thoughts. Next time i am going to cut a 3/8" ferrite rod, to about 5". I'm going to cut plastic disks, such that they have a 3/8" hole in them, and my primary is going to be double wound 26 gauge wound twisted together, not bifilar, just multistrand - about 40 turns. Then I am going to do about 600 turns on the HV - but I'm going to do my step up in stages with plastic disks in between. 26 gauge, or maybe 30 - but I'm losing confidence in 30. When I'm done I'm going to make a surrounding "coral"of home made magnetite. So it will be a ferrite central rod, with a surrounding magnetite core that has no winds on it. I got the idea, roughly - from a HV circuit in a scanner.

Hi @Skaght
With your good self we are two already who have the transformer winding problem! I wound two E cored ones and neither of them worked. I wonder what transistor you were using to get it to oscillate!
I used AWG38 magnet wire and wound 1750 turns clockwise. Trigger coil 8 turns 0.54mm wire clockwise; primary coil 8 turns 0.81mm wire counter clockwise.
Still waiting for the enlightening of Sir Lasersaber, to throw us a bone here to make it right.
I am going to try a factory-made transformer: the Tamura Microtran 3FD-310 to see if it works. Someone in another thread has posted a circuit with a similar model transformer and got the circuit lighting a CFL with 30~50 mA at 12V.

update of circuit performance

I got the circuit to light partially a 20W CFL. Using a TIP3055, and winding the coils by myself. 9VDC 100mA input. Output 450V AC p-p. Sorry, I messed up the camera, so no photos at this moment. Need to borrow another camera later. I will try to replicate Slayer's latest circuit.

A new transformer...

I ordered a couple transformers from amazing1.com (28k089) and hooked them up joule ringer style. They work great in the circuit below. I got the potted version and they seem to be able to produce the best high voltages when you crank up the power by decreasing resistance across the caps:



I hooked the output up to a five stage voltage multiplier and got some massive 1.5 to 2 inch sparks! Fun stuff.

I used a radio shack 3055, 12 volt supply. The resistor varied down to 8k ohms and the cap was .2 uF.

Nice sparks. Thanks for posting your results. How long will it run from a charged capacitor?

Normally a voltage multiplier needs AC to work. But this type of circuit mostly puts out pulsed DC. How did you connect the voltage multiplier? What ever you did seems to work great.

[skaght]

At 12 volts with a 22,000 uF cap, run time was 8 minutes on my first try with a cap and resistor (no bifilar). It's worth mentioning that that's the best run time I've ever gotten with one of these circuits. I think if I tweaked it more, I could get longer by changing out capacitance and resistance. That was just my first attempt at run time.

The circuit is hooked to a negative type voltage multiplier. It's surprising that it works so well, since it does put out mostly pulsed DC, but it does work. My lab smelled of ozone for quite some time after my experiments!
