Here is my new video, you can see my "almost OU", and help
with advices how to make that one step more :

This is cool and i got to tell my brother about this im sure his interested..and me too..keep it up dude.

[Jiffycoil]

Finished my build.

I wanted this build of the Stingo to have the complete ability to change out components with relative ease. I'm using TIP41A and TIP42A on the build now. I tested the build to make sure it working properly by powering a small pancake coil and at 5 volts 50mA I was getting 68 volts from the out put leads. I will now be able to start detailed testing. Thanks to everyone for your help and suggestions.

Anyone experience touchy stingo yet?

I have to touch the radiant positive part to lit the neon.
YouTube - Need touch to lit the neon of stingo circuit

3V stingo with PSU toroid. The consumption drop after the neon lit because stingo reduce consumption on load. Dead neon = not a load.

I currently play with this, dash blue line indicating what I imagine how the radiant go. The radiant will prefer going re circle to the power coil it seems than charging the source battery:


Or self charging can work if we add another switch on top of power coil?

Hi, my brothers in arms !...I am playing with stingo again...I tried this
new schematic but it doesnt seem it works better then ordinary stingo...
But playing again with it i noticed that i could get very close to OU by
charging the same (source) battery...I believe that father of stingo,
our dear friend Sucahyo achieved same result or even better than that...
And now, Sucahyo talks about re circling and adding another switch...
Does it mean that we are going to achieve with Stingo OU very soon
in Bob Boyce/Watkykjy manner without hex programing and Bob Boyce
toroid ?...I tried to connect earth ground with battery plus but it is not
of big help...God, help us !

[Jiffycoil]

I have had some very interesting results experimenting with the Stingo the last two days. For example voltage increase when load is added. Running DC motors. I will film these results and post them this weekend. Thanks all for posting all of your results.

Hee, heee, heeee…like I've been saying all along?

yes, it seems if the voltage multiplication is not high, it won't oscillate. The circuit also refuse to oscillate if I connect the other coil to something else.

Here is my 'doughnut' coil, too fat to be called a toroid anymore:

I have a coil that is too fat that the middle hole is closed, I have to wound the rest of the wire over the toroid lol, it still work great though.

The other thingy is a 9-inch weaving shuttle, which I fashioned from plastic fork handles and I pre-wound my 40 feet of 22 gua. magnet coil on.

nice . I usually let the wire form a U on my right side, and then slide it to the left and still keeping it straight, after wound, I put it on the right side again.

After all my efforts, Coily lit up a neon to a respectable level and oscillated optimally at between 800 - 900 Hz:

The hard work worth it .

I'm still seeking the purple neon experience, Sucahyo, or more practically, a fully lit CFL…where am I failing?

I think we can only achieve really purple neon with mechanical switching. Or maybe by switching a live circuit or something. I forgot how now. I use my modified MJT before....

For CFL, the voltage multiplication factor is critical it seems. We can not have too low or too high ratio.

Are you saying that your best performing transistor pair is TIP32C/ KSC5027?

Yes. my best.

Why is a TIP3055 your last choice?

Because I usually have almost twice higher voltage result from any transistor I scrapped from broken computer power supply.

It's 32 awg magnet wire. I only did one layer, but now I'm thinking I should do as many layers as I can fit in there, after seeing Godfrey's toroid.

My 1:1 coil produce less bright neon in series. I think impedance matter and there is minimum wound too.

Godfrey, thanks for the inspiration to use a weaving shuttle.

I wound a toroid to try the other day.

I couldn't get it to oscillate with my fan motor stingo. I think I'll put more layers on it and try again.

Currently the coil is 2 ohm and 124uH.

Drats...Coiled again!

In the time I could spare lately, I chose lab over gab to get some things done. I'm glad to see the lively post activity, since my last. I'll need to catch up in increments as time allows.

I also notice that shorting the secondary will stop the oscillation.

It did not light a CFL, which my car coil can do.

That look like a half dead transistor for me. I replace transistor if I experience that.

I haven't given up on Coily yet, so today as we speak, I'm in the middle of changing out my transistors for two fresh ones and then will test the old ones on my meter.

I use only TIP32C for PNP now and my best result for NPN is with KSC5027, 3055 only as last option. TIP31C die reather quick playing with spark

Thank you sir. I'm going to build it in the next few days. I look forward to trying to replicate your results.

Ok . Look forward for the result .

Do you suggest Bob Boyce toroid winding too ?

If anyone can try it. It is a lot more demanding to build. Bob Boyce use military spec wire that even wire twist is not allowed. The toroid is also hard to get, Micrometals T650-52.

See panacea document about electrolysis.

I just started playing with the stingo and got it to work with a 3906 PNP and a C6081 NPN. It worked with a single 1.5 volt battery.

Great and thank you . The reason I search 1.5V transistor is to try to modify my son toy with stingo motor. To see if the toy can really run faster and to prevent my son running around chasing it if they get out of track. With stingo the toy would stop after the first hit . And to run it again we just need to push it, no need for switch .

I will try to find those transistor here .

I tried to take it up to twelve volts by putting three 3906's in parallel (which still worked at 1.5 volts) but it didn't oscillate and the PNPs get VERY hot very quickly.

Add 100 ohm to PNP base. I recall that we need to add 10 ohm resistor to parallel NPN, to allow them switch at the same time. But paralleling transistor is usually done to reduce amp that flow to each one, not to increase voltage.

[cikljamas]

Oh, and I did have to raise the base resistor from the 10k pot up to 47k ohms to get it to oscillate...

I did the same thing, but it probably differ depending of kind of
transistors that you use...

First attempt with stingo...

I just started playing with the stingo and got it to work with a 3906 PNP and a C6081 NPN. It worked with a single 1.5 volt battery. I tried to take it up to twelve volts by putting three 3906's in parallel (which still worked at 1.5 volts) but it didn't oscillate and the PNPs get VERY hot very quickly. The only reason I used those transistors is because I had them on hand. I used an ignition coil and also tried a couple air core coils that I had from my Slayer exciter and they all seemed to work fine.

[cikljamas]

I use 240V/24V. But I post it not as requirement. But that coil happen to work best for me previously. Now I suggest toroid winding.

Do you suggest Bob Boyce toroid winding too ?

I don't think it will produce measureable current but some believe it can accelerate charging.

Anyone notice measureable output increase if you touch PNP base of stingo?

I did not, but i hope i will if i try...Interesting suggestion, thanks!

Maybe the wheel SSG one.

Thanks for picture, but it would be better solution if you could find
bigger one
