Stingo Solid State Battery Charger

[7imix]

The difference I noticed on the oscilloscope between the stingo and bingo is that the bingo's fall slope is much curvier -- the stingo has a very sharp fall. I plan on building some bingos again when I get back to trying to design a low power stingo, but I have too many projects and not enough time right now... I want to do some stingo spark gap/capacitor experiments, and I have also started a new line of experiments with my Ghetto Coil air core transformer from the "This is it!" thread being driven by the stingo. I was able to charge a capacitor off the secondary through two diodes, and run a dc motor off it -- but the amp draw was too high.

Yes, I remember cooked battery. Did you revive them back still with one diode? That is interesting.

Maybe if you can make bingo work in inverted mode, the result would be different. Maybe more conventional electricity in bingo change what being dump into battery.

The difference I see between bingo and stingo is the bounce back current. Definitely something can not be detected has change result. I would also interested to know why.


As for brightness. What if we calculate twice brightness require square of power? Using logarithmic scale?

I still do not understand what you mean.

You propose that using 3V is better for your LED driver circuit?

I look at your photos, is that joule thief and your circuit combined together?

10uAmp at that brightness is awesome !!!

calculations

I just made some calculations on this 5 + 1 leds test...

So, here we are :

This 5 leds torch of mine that i have been presented between Christmas
and New Year drains 9 mA when i put it as a load to 12 V battery and
with two AA batteries (3 V) it drains 10 uAmps, so lets see this in numbers :

0,000010 A * 3 V = 30 uW

0,010 A * 12 V = 120 mW

So how much we spare with this joule thief variation ?

120 mW / 0,030 mW(30 uW) = 4000

So, we waste 4000 times less energy like this....

But since the brightness is not the same lets suppose that this leds
lit 2 times brighter with 12 V battery, it is still 2000 times spared energy,
or if we supposed that 12 V battery gives my torch 4 times more brightness
(and that is the most possible extreme assumption) we would still waste in that
case at least 1000 times amount of energy in this fashion !

Isnt that cool ?

And with 2 mosfets inverter we spared just 3 times amount of energy :

0,5 A * 12 V = 6 W (for/with 15 W bulb)...

So, any comments to that ?

Sucahyo, i did not ask you this before, but i know that you remember
how i cooked several batteries with my bingo ?

After that happened i made some measurements and if i remember
well (and i think i do) output of stingo and bingo was the same = 75 V
using same current as well lets say about 300 mAmps...

Now, since i charged yesterday and today several small batteries
successfully with stingo (with bingo i will never again try to charge
small batteries), i tried to figure out why bingo cook small batteries
(positive-negative mode, not negative- negative i used of course with
bingo charging small batteries) if his (bingo) output is pretty much
the same in positive-negative mode as stinogs output except bingos
efficiency is to some extent bigger than stingos efficiency ?

That difference in efficiency should not be the reason for cooking small
batteries, but what else could be that mysterious reason ?

I posted interesting experiment in "this is it" thread, i will copy that
post here too :

how close
Hi guys, i am jealous of your forward steps (a little bit), and i have to
ask you 7imix, what are the chances for you and me to make any
progress with this project using your ghetto toroid ?

I`ve been messing around yesterday with this :

http://img339.imageshack.us/img339/2865/howclose.jpg

And these leds are lightened guess with how much uAmps, not mAmps ?
With 10 uAmps !

In two hours these two AA batteries depleted for guess how much mV ?
For four mVolts !

So, how close to OU is this ?

Cheers !

Cheers !

Thanks i'll see if i've got one.

If you have a look at Figure 4 of Tesla Pat. 568 178 , I think that would be the easiest best way to do it. I'm thinking glueing a plastic bolt or something to the back of one plate for adjustment, that drawing Fig 4. Shows the cap plate's on the secondary as a regulating arrangement I think. But since i'm using a car coil output on the primary thats kinda what I think I need, but smaller and closer together. I think I need to try it, see what happens.

Or if you try it first, make sure your video is taping, so if you get zapped when you wake up you will be able to find out what happened.

Cheers

Thanks for the patent link, that patent looks amazing. It's astounding how many tesla patents there are that I still haven't read... and I've read a lot...

The disposable cameras used in the Joule Ringer have some nice high voltage caps in them. They probably have a nice Q as well (fast discharge) because they power the flash.

But making our own capacitors would rule. I want to try.

Haha, i'm always surprised when things work first go for me sucahyo.
But I wasn't amazed because it was Stingo.

I might set up the tower coil thing again tonight, if I do I will take some video.
I did get a better result for lights thats for sure. I still need that HV cap for
real good effect I think, a small spark gap and a HV cap. But I don't have
the cap. I think i'll try to make a variable parallel plate capacitor from some
1.2mm aluminium plate. Later on some time.

Great, I will look forward for your result .

Agree that it may be better to make our own HV caps.

Hi Guys, I got mixed results with my tower coil experiment, it worked fairly good for wireless lighting a 280mm tube and a cfl no problem up close but no fantastic or spectacular output or anything, yet. Lights neons ok from a short distance and such.

Nothing overly exciting to report except that my Stingo worked first go. And performed very well.

Surprising. But not Amazing .

Lol, I guess that is what happen if you get too much very good result on your previous one.

Isn't you already get the expected result? or there is something you don't achieve?

What do you see as amazing now?

I have been trying to get Joule Ringer COP, with stingo, lighting LED with only capacitor. Maybe you can achieve it with tower coil?

Sucahyo what exactly do you mean connect it to output postive?

Here:


Try it and see if you can notice current or voltage increase.

Although on stingo you may observe some voltage or frequency change too if you touch other part....

I feel exactly the same way about American Beer!

Lol, I do believe that we can even use stingo to make beer tastier, never try though ........

What is this "cap dump technique" you are talking about ? Sorry I am to lazy to look for it in past posts right now.

It is not mentioned here, it is method of charging battery by storing the radiant charge to a big capacitor first. After the capacitor is full, it then charged to a battery via SCR or mechanical switch.

The cap dump technique also dump the charge at "slow" rate of 2 seconds each.

I run stingo on my office as long as the battery last for two weeks. 4 of my friend mention good smeel, good feeling. Stingo or any other electronic circuit can produce good and bad effect, please be carefull.
