Super Bright Fluorescent Joule Thief

Categories:

Pulsed Energy Systems

NOTE:: the frequency noise is only picked up by the camera. it doesnt actually squeal like that audibly. alot of people have made some cool portable fluoro lights on youtube but none of them were bright enough for me. “boomerman2004″ has made a great instructable on how to do this at s821.photobucket.com i basically did the same thing and took cheap camera circuits and gutted them, but used 3.6 cell phone and cordless phone batteries as inputs. one of them is actually one of the battery cells that make up a laptop battery. each put out around 4v at good current. the problem is leaving the lights on for too long will burn out the transformer. i added a 25 ohm rheo on the green box so i can leave it on for however long i want, just at a low brightness. i wasnt satisfied with the light a single AA puts out, and i like the rechargeability of these battery packs. they charge super fast and will last like almost forever in these circuits. i will definitely be using these next time the power goes out. room to room portability is what makes it ideal. u could also create an inverter for a car battery that will run much bigger fluoros during outages. the pope is a faggot and im going to spinkick that fool in his big ass head ay seriously tho if u like the pope u need to sit on a pinecone and twirl true story

    @SpeedMetal4635 this circuit can provide some nice warm lighting in a room, but i have found that using certain LEDs in a circuit can provide more brightness for less energy cost, the color of the lighting is just a little unfamiliar. you have to get used to the “blueish” tint of the led lighting.

    @SpeedMetal4635 well for one you have to make sure you are using the AC from the circuits transformer and not the rectified DC. this will increase your output a little. you can also try adding a high value AC cap across the output legs also. i simply recommend using a larger battery pack to drive the circuit. i used a 4.5v battery pack.
    i really recommend buying some 3.7v 4Ah batteries online. those will work great at providing brightness and last for a long time.

    hello, I use another flashlight circuit from kodak camera and really works! but the CFL isn´t bright enough. how can modify this circuit to make more brighter the lamp? thanks

  • SpeedMetal4635

    @Magneticitist thanks, I will still trying to do this project, is very interesting. There are very poor info in the internet. I will wait patiently for your tutorial. Thanks. and sorry for my english :S

  • Magneticitist

    @SpeedMetal4635 ive tried bigger flash circuits also, like one from a polaroid. it was harder to get working cause u have to find the right switches and such, and that one worked from only 6v and up. i will try to make a tutorial for you here in a bit. but since the circuits vary somewhat i may need to find out which particular one u are using.

  • SpeedMetal4635

    hello, I try to do this project, but don´t works, I read the tutorial but i´m using another type of flashlight, is much bigger than boomerman uses, and is so much more complicated because have a lot of components. Well can you upload your own tutorial easy to understand for us? thanks a lot and great job..

    @Magneticitist
    when you enlarge the file(bmp) the fonts get messy cant read them

    @Magneticitist

    what the configuaration is the joule thief wired up as?

  • Magneticitist

    @eloid777 it might be on your end, i just clicked the link and it worked. or maybe it was down when you tried it the first time.

  • Magneticitist

    @eloid777 all the cams are pretty much the same. you rip the small circuit board from the plastic case and u end up with a little pcb with the AA battery terminals on one end, and the capacitor/flash bulb output on the other. you just remove the capacitor and flash bulb and the circuit can be used to tap either high voltage AC or DC, depending on where u tap from, before or after the circuit’s diode. there is also a switch (metal push switch) on the bottom that u need to solder so it powers on.

  • Magneticitist

    @eloid777 oops.. i may have to create my own diagram soon lol. for the camera the easiest thing to do is use a disposable cam. i used an old polaroid once, and it worked great, but it was much harder to setup because it had some complicated switches and variables. there may be some disposable units that work better than others, but to me they are all the same for the most part. i try to find one for under 5 bucks, or for free if i can.

  • eloid777

    the web link is bad cant read the text

  • eloid777

    can you draw your circuit, what kinda of dispoable camera the old film types? there hard to find with everythink gone digital?

  • Doug3445

    Nice! just bought a throw away camera and tested it on a strand of LED’s, and it works like a charm!

  • Magneticitist

    @coolelectronicdude lol me too man

  • coolelectronicdude

    well mama told me when i was young said sit beside me my only son….. be a simple man lol love that song its great!!

    Hey Magneticitist thanx for givin people the link to the TEEP forum and the topic that I posted. Its good to know that it is getting out there to people that want to learn more or are intrested in these types of projects. There many things that these circuits are capable of that a lot of people do not know about or understand. One of the things most people dont know about these type of circuits is the capability of wireless electrical transmission! If they visit TEEP forum they will learn!

    @Br0kenMan cant measure the amp draw at the moment.. burned out all my meters playing with fire lol

  • Magneticitist

    @Br0kenMan every time it rains =)

  • Br0kenMan

    Holy usable light batman! Nice production and the mic interference says alot about your circuit. I am getting similiar light from my flouro wirelessly on a little more power, but not quite as bright. Any idea of the amp draw? I guess we won’t be going for the candles when the power falls off the grid. I bet your just praying for a brown out!

  • MrAnguswangus

    Very nice light man. Those are a great idea and I have a ton of those 3.6v battery packs…gonna have to look that up and make one…or three.

    Funny you should say that about the pope because there actually is a big pine cone at the vatican next to the obilisk…lol. They worship them because they resemble the pineal gland…or some funky ass witch doctor bullshit.
