Joule Thief (Fluorescent Tube) 013

[greensleevespw]

A GOOD PAIR OF POWERFUL MAGNETS CAN BE FOUND ON THE CAVITY RESONENCE MAGNATRON IN AN OLD MICROWAVE OVEN. ENJOY:-)

[phoenix2038]

is that a switch?

[phoenix2038]

amazing

you have the neodynium magnet, 12v battery, coil, neon bulb,

and what is that little metal box?

[freethisone]

how do i take apart the florescent bulb, without breaking it? thank yyou

[MrHaddadou]

please send me the schematic wiring

[ciprianwiner]

ok so i understand now, thanks alot man i just need to find another transistor... because i made a flashlight with the one that i had so THANKS PAUL

[AppleShinny]

i have maked it without a joulethief and connected the two wires from one side directly to 12v and it worked!

[MikiElectronic]

@AppleShinny

But how long it work?!?!?!

[hristip]

gut

[raunakmantri]

Rise people Rise!

Do you want your children, brothers, sisters and loved ones to be RFID chipped and enslaved?

It is us in electronics community who are the soldiers of humanity and freedom.

We can awaken the masses by displaying free energy devices and telling how to make them.

Else you can choose to make free energy trash, hide results and make sure that your RFID chipped daughter is an ignorant dumb sick human being.

[gadgetmanubuntu]

I wonder if wrapping the coil around the magnet would work?

[TheKaos90]

@gadgetmanubuntu me too ; I'd pull apart a 50W subwoofer that has a 10 cm diameter neodyum magnet , so if the principle helps ; AWESOOOOME !!!!

[stevenchiverton]

i had the same problem to a small fluro like yours and it had 3 u shaped bulbs in a circle and when i powerd it with my joule thief useing the same kind of battery you did only part of one of the 3 u shaped globes lit and not all of it there just aint enougth power delivery to the lights

[blaargenheimer]

Are you using a pickup coil on the joule thief torroid, or is that straight off of the thief(i.e. between the C and E of the transistor?

[Mrxxx007100]

what is that coiled round thing, is it a magnet coiled in insulated wier.

[newbeatlee]

so nice but have you a circuit's diagram to make one ? thanks

[MattBlytheTheOne]

this is very interesting the effect the magnets have on the coil output, are you using a 1.5v battery for the input? a CFL bulb is a bit like a flourescent tube, once the gas is energised using high voltage you can reduce the input power, that is why they are low energy.

[MattBlytheTheOne]

you can quite easily step up 12v to mains voltage through an inverter...

[a380rockerfan]

yeah they are cool

[malaki013]

i have no idea what you guys are talking about what with the "torid" and your "CFLs" but, man this shit is facinating!!! i love magnents!!

[knowledgemonger]

Your local library, likely has books on physics and electronics. Read a few of the very introductory ones and then see if you can find "The Art Of Electronics". You will discover stuff that is simply amazing.

[MattBlytheTheOne]

great tip thanks :)

[knowledgemonger]

Next time you ride in a bus, notice the lights they use. Lots of buses use fluorescent lights. The circuit for taking 12V and converting it to the higher voltage needed by the lights is fairly simple and low cost.

Fluorescent lights can be used to make a moderately good strobe light but these days, LEDs look like a much better way to go.

[kubikop]

I think you might be right, I've got some 12v LED's that I'm going to try..

[Lidmotor]

This is really good news. Lighting a CFL straight off a JT-----WOW!

[kubikop]

I know have you replicated this yet?

What Power Consumption is your ignition coil setup drawing?

Paul.

[Lidmotor]

Paul-- I worked on this yesterday but I need to wind a bigger Torid coil. Power consumtion is EVERYTHING to me. The CFL projects that I have been working on for over a year are all about lumens of light vs joules of energy. The ignition coil arrangements I have worked with draw 20ma up to 3 amps. depending on the circuit and light output. I like where you are heading with this. I tried the magnet trick on a small JT coil and it worked just like you showed in your video.

[kubikop]

You can use microwave magnetron magnets as toroids and the magnet trick is inbuilt......kewl huh.

Mine was pulling 800mA at 10.4v = 8.32 Watts and it was a 11W tube but only running half of it.....

Have you tried finding the resonance and pulsing in that frequency with a 555 Timer? I think thats where I will go with this then once I know the frequency make a coil to suit.

I am thinking induction heating would make a difference also and scrap the two heaters in the tubes, what do you think?

[Lidmotor]

I have a Torid wrapped around a speaker magnet but I have not got it to work yet. I tried to run it on a 2n2222 at 2.5v. Will try it with a TIP3055 and 12v and see what happens. The CFLs I use don't have the heaters in them. They turn black at the bottom but still work. I have not tried finding the resonance frequency with the 555. Lots of things to try.

[kubikop]

All CFL's have heaters in them as far as I know, they are what glows orange before the tube fires. A 3055 will make the difference.

I have two 10w LED's on the way, if a 20mA LED will run at 10mA a 10W will run at?.......5W

[knowledgemonger]

No, the CFLs don't have to have heaters in them. They are struck by having an inert gas in them. A high voltage fires the gas which gets thins started.

BTW: The 3055 is a rather slow transistor and not very good as a switch for this sort of purpose.

[Careica]

Something is realy happening! Quess what would happend if you wound that wire around NEO magnet :)

Good luck!

[kubikop]

Thanks!

[Nabo00o]

Hey nice video kubikop!

I think what actually is happening is that you are placing a ferrite-magnetic material close to the coil, and thereby you are increasing its inductance, its almost like increasing the number of wirings! So you are probably increasing the amount of charge which this coil can hold and then release, your voltage can go up. And if you don't have any capacitors in this circuit it is most probably not related to the change of a resonant frequency.

[kubikop]

I thought that but its not. More about that later.

the transistor is rated at 70v if that helps......

[Demoman42]

interesting video, 5/5

[kubikop]

Thanks.

[37474748]

hehe i bet you have some radio active gue in there man :) sweet video 5/5

[kubikop]

Cheers.

[seshkanuri]

You mentioned "It appears that this technology is completely Coil dependent."

Do you mean coil independant?

[kubikop]

No I meant it dependent on the coil, as you get the same voltages out at lower voltages in.

[dodoshlodo]

strange that the neos make a difference, well done!

[kubikop]

Cheers,

I know why too, Well I have a theory....

[dodoshlodo]

care to share your theory???

I have built this setup almost the same, 0.4mm bifillar, toroid, Bedini "twisted" wire, 2n2222 transistor....

But i cant get it to run a cfl?

do i need power transistor?? what rating resistor are u using to get it into resonance??

-yuor help would be much appreciated.

[dodoshlodo]

oh yeh, i have around 80 turns

[kubikop]

You should put a neon across the collector and emitter too incase the Fluorescent Tube gets disconnected. If the spikes are not going to the Tube they will go across neon and not the transistor.

Use solid data cable 80 turns should be better than mine.

its just a 1K resistor but the resistor does not matter that much, use a variable resistor and you will see / hear that the resonance changes.

Let me know how you get on.....

[dodoshlodo]

i did exactly that, works great. getting very high voltage spikes

I used 90 turn bifilar "Bedini Twist" toroid and it resonates from 3V onwards. Charged a cap up to 400V from 3V (100mA)

u mentioned 555 timer, wats the point, like u say u can vary frequency with a pot

[kubikop]

To get it in resonance we need to produce a very high frequency... About 1.5Mhz for my small coil..

Please see next video...

[daenumen]

@kubikop NEODYMIUM

[kubikop]

Upgrade your 2n2222 to a 2n3055......

Is your coil a toroid?

Paul

[dodoshlodo]

cheers the 3055s work good, i can light those 90V noen but not CFL.

[kubikop]

Glad they worked Im using a BD243A Transistor it may work even better with one of those on your coil.

[dodoshlodo]

ive built a few thief but i cant get HV to light a neon.... i have very thin wire (0.3mm)... wat is the secret Kubikop?

wat gauge should i be using??

[kubikop]

Its in the info bar...... Bilifiar 45 Turns 0.5mm

If you replicate it post a video.

[rlewis1946]

Would "recycling" the coil's flyback energy in a large array of florescent light fixtures - say in an office building - make your circuit a commercially viable product? I hope so and if that's the case, I hope you have already filed for an international patent!!

Keep up the good work.

[kubikop]

There is a more efficient Circuit I have not show and I am thinking about it, but It cost money to patent in england....

Paul..

[skierplaterandy]

what does the jule theif actually do? is it like a transformer?

[kubikop]

It collects the Flyback Voltage from the coil, This is usually grounded by a diode. It is a transformer a 1:1 transformer so theoretically it should only get 12v in 12v out but everybody overlooks the Flyback of the coil.

It works on the same principle as the Bedini Motor. I am in the process of designing a more efficient one so I can use all these designs to create my own separate circuit.

One Sentence answer is its a DC to DC converter.

Its Kewl aint it....

[skierplaterandy]

huh... awesome. now i have an idea bt can you clear me up on what the "flyback" voltage is. i've seen it in a few of your videos but i couldnt figure out what you were talking about.

tanks:D

[dodoshlodo]

its the Back EMF or the spike of voltage that flys off the coil when u pulse current through it. Conventional electronics would damp out the large voltage spike so it doesnt burn transistors and other components.

Kupikop is smart and is capturing this spike

[skierplaterandy]

how though. like i know about the spiking and stuff but how do i harness it?

[kubikop]

You invert it and put it back in as a positive spike

[skierplaterandy]

ok, can you post a video or a shcematic. that would be something ill try.

[kubikop]

I will draw one up when I get a minute but its the same as the one on the energetic forum I posted link is on earlier videos.
