Hi folks, Here is the lasersaber/minoly mod for the SSG circuit.

edit: had to move the base diode back and place a base resistor at first transistor. Now it looks right.
I fired up my setup, though with only two strands for now and it is working as minoly has said, though I'm using a 1uf-250volt capacitor instead of 10uf. It is drawing 180 milliamps with the 2 coil strands, though I have another to use. It is charging well even with just the two strands so far. Also, I am using 1kohm base resistors instead of 100ohm.

Hi Tyson

thank you for the digram but when i watch Minoly video i noticed that there is two big caps ,I dont see these caps in the diagram can you show me where they are hooked ?
and i am thinking of using Mjl21194 transistor what you think?
i was depress and now i have some thing to do with your help
thank you

Hi Ehsan,
they are parallel to the batteries - one each, I'm not entirely sure they are necessary.
If you have them, put them both as close to the energizer as possible. My thought was, I want the energizer to see the caps not the batteries. Again I'm not sure that is really possible w/o the comparator - cap dump system.

Velleman kit.

Emboldend by my Velleman flip flop triumph, I dove into their Voltage regulator pulse width modulator kit, which came off like a dream. This circuit scared me at first, but turned out to come together just right. Next step is to use just the regulator combined with the Xee2 circuit with the 1K pot on the transister base capacitor tank. Xee2 shows how the base tank resistance value changes with the change in voltage in his first video. These are mutually shifting values. Change one and you have to change the other to sustain peak efficiency. The two seperate knob adjustments will allow for this kind of precision tuning. Magnetman's "French Inverter" really needs a frequency control pot to adjust the Hertz when the voltage is changed, to achieve maximum efficiency. I plan to couple the Velleman regulator with a "French Inverter" modified to allow for variable a.c. Hertz control with the additional transistor base tank potentiometer as a follow up, along with power measurements.

Hi folks, Hi ehsan, I am actually using the circuit in this pic, this is the circuit I have been using for some time now, though not with multi-strand, and it works very well.
Though I was able to get the other circuit working as well, the one you just posted.
Don't forget neons across the transistors for a visual warning to shut down the circuit, as depending on transistor rated voltage, will be damaged eventually.
I'm just about ready to start my testing.

Hi tyson,
can you please give the resistor value / watts of the trigger coil which is only written as Rx my parts are complete except for that one .....

thanks

Hi totoalas, Well for my setup I used a 10kohm pot, which is all i had on hand, though I'm sure a 1kohm pot would work fine, as minoly pointed out, find the sweet spot, then measure pot and replace with fixed value resistor.
My base resistors are 500 ohms and with my setup draws 360 milliamps, if the dmm is accurate.
I don't have a scope so I'm just watching battery voltage climb rate verse amp draw.
What I feel is important with these radiant chargers, is the largest voltage spike possible with the least possible current in the radiant spike, so the charge is solid.
Also, My 360 milliamp input is in line with the C/20 battery rule for my batteries, as is my discharging of my four battery parallel charge bank.
This should give optimum efficiency.

edit: also I just did the 1 ohm resistor test on the radiant spike output.
Voltmeter shows, .516 volts, or 266 milliwatts is all the power being output in the radiant spike to charge a 12 volt-28AH battery bank at a good rate.

Thanks Tyson for the quick response

Can i crushed the tv crt toroid, pour with glue in my air core and or just use welding rod iron .....
thanks again

I wonder, does anyone know if the circuit at the top of the page can be scaled down ?
Got no automotive batteries here of any usefulness..so...
A tiny build, intended to see about charging AA's etc, has been found to be naff. Or, perhaps is fine, just too small a set of figures are passing through it.
What happens is, when the trigger coil is connected as per the diagram and a 1.5V AA used as source, 11.25mA are drawn and the 5K pot will change the output from 0.001V to 0.005V (seems to reliably change, rather than be a meter error).
The current draw rises to around 19mA if the pot is fully wound down and inbetween will show the difference.
If the trigger coil is connected to the positive of the supply, nothing works, nothing is drawn.
Components are:
Transistors 2SC2785, 1N4148's, 1N4001's instead of 1N4007's, '225' 100V cap, 5K pot with 100ohm resistor, 7 strand former Romero type litz coil. 1 strand forms the trigger, 3 strands form one winding, 3 strands form the other.

Attached here to a 5.5V 1F supercap, just to show the sort of size i'm shooting for.

The Sentex KyleMod 555 Oscillator DC to AC Inverter (12VDC - 120VAC) 1 watt

A bit strayed from the Joule Ringer, but...

Here's a great little inverter from DC to AC Inverter With the 555 from (C)2002 Tony van Roon that I modded slightly that I find a lot of fun for running 110 VAC LED lamps on a 12v battery. I call it the Sentex KyleMod. All parts are easily had by recycling dead stereos / UPS's etc. No Centre Tap Transformer needed, or any triggering issues. I learned that by modding the oscillation frequency and filter capacitance you can get this little inverter to be conservative on the amp draw, quite cool! She puts out pretty good light at 12.8 volts / 70 mA (1 watt). After the vid, I did further mods and got it down to 50 mA, for the same light. There is lots of room to optimize this further I want to push the frequencies and voltages higher yet, work with some ferrites if possible Build one and let me see what you got! Please excuse my bad terminology, I'm new to this stuff

Here is a demo vid:



Thanks and Merry Christmas people!

Hi folks
thank you Patrick and Tyson I have some couple questions ?
what is the value of these big caps?
the digram tyson using the coil has #18awg wires and in Patrick video he said that the coil is #23awg wires so which one is the best ?
thank you

Ehsan

one more qustion
tyson in your set up you used an air core coil and patrick in his video I noticed that he used welding rod corecoil so which one you think is butter?

[SkyWatcher]

Hi folks,
@totoalas, I would use welding rods if you can't get find manufactured ferrite core.
@slider, I have not tested hooking trigger wire to positive rail ,so i don't know if it works.
@Hi ehsan, I am using 23awg magnet wire and a ferrite core scavenged from audio speaker crossovers. If you can't find cylindrical ferrite core, use welding rod, it seems to work well for minoly.
I decided to solder everything I could together on my setup, to improve output and stability, so will be testing soon. proto boards only good for verifying working circuit.

Hi.Here is a youtube vid by teslacult of his double joulethief which is ringing like crazy.Much potential with this one.
Self exciting generator - YouTube

@Kyle.Great experiment .Are you using a low power 555?It may save a few more mA although you seem to have it dialed in at 50mA .Jonny

I'm not sure... it is marked LM555CN. The transformer is a fairly large one, at least 1a 120-12 stepdown. I'm going to look at things on the scope when i get a chance, see whats going on. i'm running with no resistor off PIN 3, at all, no inductor on the filter (only a single 470 uF cap),a 47k pot to the top rail, 10k tuning pot - and 20 nF timing cap to (-), fairly bright at 40 mA, and it's now starting to ring a bit. If you go down to 3.9 nF, it'll still oscillate, the ringing disappears, draw is around 30 mA, but you do lose some light. Basically I am trying to rid the circuit of reistors as much as possible, and get the frequency high enough that I might incorporate ferrites? Also, I need to try using a 6v - 120 transformer, I am only measuring 50VAC on output. Cheers

Hi folks,
@totoalas, I would use welding rods if you can't get find manufactured ferrite core.

I've decided it's time to upgrade my Bedini Desulphator for my solar system, been looking at the latest SS SSG configurations people are using. I once bought baluns from this guy, in the Ukraine, and he was good to deal with. (* side note they shatter VERY easily, I wrecked half of mine, one drop on concrete and they are DONE, plus, they are slightly warped, and thus start rolling when you'd expect they wouldn't!).. anyway, they are relatively LOW permeability (400?) for these 8mm's. Mine were 10 mm's. I simply built my own centre-holded plastic discs, and glued them to the end of the baluns, which I first applied shrink tubing, to...

My question:

With the welding rods, A. Where do you get them, such that they are not coated, or.. are they stripped of their coating? B. Is relatively low permeability the goal here, one would think welding rod cores would be low... C. I wonder how it'd work if you simple used bunched section of rebar iron tie wire?

Thanks.
