You need to dip a ready transformer to a vanish epoxy (make it warm for better results) Best is to make small box and fill it with epoxy. this way all sounds will go away. You are making fantastic work there! Thanks for sharing!!!
Thank you for your hard work and for inspiring creative thinking. I made the Joule Ringer 2.0 and it works nicely. It will light an incandescent, but that's a waste of watts. I think this is a more useful circuit for multiple light bulbs. For a single bulb the joule thief is quiet for sure. I am not so sure the coil winding is so finicky. In fact I am not so sure this idea of a single transistor wouldn't work with a quiet air core coil Inductor. My circuit starts up nice.
If you notice in the video only one of those wires are used but he uses two wires in parallel so that you can hook it up bifilar if you want to as he had mentioned in the video so it is there for experimenting with but the schematic shows the present experiment only
Very very nice !! I just recently salvaged some cores like this and found that they do squeal very bad!!! But found that of you glue the cores back together your quiet that down a bit! Manny blessings and keep up the good work! Cheep and easy! Love it! ~Russ
You really have a great and easy to replicate device there laser - thanks for sharing and showing these videos. They are perfect how to's for beginners, and I'm sure they inspire folks with no previous circuit experience to get their hands dirty. I dont understand how anyone can dislike this video - low power, lots of light. Only people who like paying for electricity could dislike it! Anyway, Im off to your website to replicate....
The transducers are brazed to stainless steel plates that make up the walls of a cleaning tank. They would be wired to a sweep frequency generator, and the sound will be directed into water. Don't worry though, I won't be sticking any body parts into the water when the generator is on. Wouldn't be fun.
The ultimate JR P1 Info to all J. R and TPU Enthusiasts. I have a TV/YOKE that wouldn't accept any sort of winding or Transistors; the output voltage was always lower than what I put in. It’s small, circa 3 inches in D, cylindrical outside, concave inside, and easy to wind. Chose to be bizarre with it; 60 turn of Antenna's wire, single wire; wired like any JT, and hey presto! The V. Meter went crazy! Connected a 110 V LED B on the collector's diode; it was as bright as sunshine. More to follow!
I watch your videos frequently and have replicated a few of them. they work just like you describe them. I really appreciate all the time you take to do this and your explanation of each experiments are very easy to understand.. I have learned a lot from you and I look forward to your latest projects. Would love tto talk to you sometime. Thank you for all your videos on You Tube.
Great work your videos are always vary informative, also about the tapping to start the circuit, old fluorescent lamp ballasts required a starter it's probably a similar issue keep up the great work
I would speculate that with the increase in load and the decrease in the audible tone is representative of an increase in current draw which slows frequency as it causes more current to be drawn during each switching event. That means the volt peak amplitude is being reduced as the current draw increases... It should all be present on the scope over the collector/base of the transistor. :) Good stuff man, I'll see about replicating. :)
Exactly what I saw tonight. Its linear. If voltage is low in relation to the load the amp draw goes up and frequency slows. My voltage x amps was very close to the rated bulb wattage. Only when voltage dropped to 4.8 v did the power output drop below rated watts. The ringing didn't start until the load was too much for the voltage.
I am super impressed with your work. This can be a start of free energy. It's people like you makes the world difference. Can you please send me a step by step instruction on how to built one?
I took a look and the schematic for this is the exact same schematic that I used in my exciter videos, except instead of being open ended, the bulb is connected to the negative rail and there's no resistor on the base.
Right on, I'd think that given the start method of having to touch multiple times is due to no direct path for the oscillation to start which would normally be done by putting an 18k ohm resistor from the collector to the base, that should ensure it starts everytime connected. (since it will bleed thru and start the oscillation.) Otherwise maybe try putting a magnet near it to start oscillation if it doesn't start when connected. Its the initial shorting to power that causes oscillation.
"I can see myself in some dystopian future using this as a flashlight" I laughed so hard at that. Keep up the good work man. And thanks for the new video.
Oh. I wonder if it cold be pushed to 20 or higher. Could be useful. They sell magnetostrictive transducers which are similar to transformers, but they are really expensive.
Hi laserhacker why are you using a bifilar coil for the primary coil ? in your circuit diagram it is different. There is only a normal primary coil.... hmmm
i think you get the ringing noise because you need to submerge your transformer in resin, this should stop the ringing noise as its the vibration of the wires and you will find that you get less loss through the transformer as well.
Have you ever experimented by putting a magnet around the transformer? I had a ferrite torroid on a small joule thief that screamed and was able to quiet it down and the led got brighter by moving a magnet around
mine doesnt ring this circuit is a god bless to the world i leave the led lights on in my workshop all the time using only 10 MA draw with 220 volt led lamps cool white. this circuit is a winner
Wait a tic, you wound primary double wire and used only one? I see the two unconnected wires from the transformer.Does that mean it was unecessary? I love this SJR2 maybe more so tha SJR3 but I noticed SJR3 used 1 layer first then another on top .Oh boy, you deserve a million $ for such time and effort! Great job man!
About the acoustic output, see v=-KzugLhMB9A. Or just make an oscillator and use a high-power transistor amplifier. Or make the resonant frequency be higher than human hearing. Or a string of diodes to multiply the dc voltage derived from oscillating low voltage current.
Howdy, I replicated this with the same 20awg wire and the nebraska surplus transformer and used a 5watt led bulb where you noted the 1.2watt led bulb. I got it working last night but it draws over an amp at 12vdc input. That seems rather high given the figures you've noted. I have a pic of it and the schematic I ended up using to connect it all up. Looking for some advice on how to get the lower amp draw you noted. (oh and ur right, it shocks me nicely if touching the base of the lamp!) :)
Hi Lasersaber. Awesome job as usual. I'm a big fan of yours. I know you have been asked this before but I must have overlooked it. What is the transistor in this circuit? Thank you.
Can you build this and film it. In your videos you don't show show step😢😢😢❤❤ by step building 😢🎉🎉🎉 please 😊😊. Show us how easy to wind as you say. M new here, 12 years later 😅I want to build. I like the other Joule Ringer video with battery and one transistor, please do another video 😊😊😊
have you tried a small air gap in the form of a peice of paper between the cores - should reduce the noise. or clamping the core - try a tywrap. generally PVC wire does not work well for transformers as any heat generated will soften the insulation but its cheap and works. when you have a final design try soaking the whole transformer in varnish to reduce the squeal. the squeal is caused by the large pulses of DC current in the circuit.
About tapping the circuit... On my bench I noticed that sometimes coils wouldn't kick start because the seem to be some remnant field bouncing around in the circuit. I usually just touch the ground wire to the trigger or just touch it with my finger while having my shoeless foot to the concrete in my shop ;0). In my case it always starts from the first kick after grounding it. I might get a shocking surprise one day... ha
Thanks for all the info. Have you tried a momentary switch with say 2K resistor between B & C to alleviate the need to fiddle with the power lead, when she doesn't want to start, right away? I find this very useful in my solid state Bedini's / Slayers etc. Thanks for the update.
All fine and well with your inverter once you eliminate the awful noise but then the efficiency is shitcanned right out the window without recovery of the light or energy with some type of flow storage. Just something to think on but why not run power to a hairpin circuit with CE circuit to power even more?
I used a 5k pot between B and C... worked great Ummm sort of...lol . With a 8.5 V power supply, I could light 40 W CFL very bright, a florescent tube and a LED party bulb. Using the 5K pot to adjust. I also used a 2n3055 transistor. All went well until I smoked my 5K pot
With all that noise I have no idea what you're talking about. Do you have proof that your experiments really works? Or do you have some hidden power point under the table?
that would be perfect for a joule ringer for a pack of crystal cells. We are designing a circuit so that we have the crystal cells going to an op amp and then the op amp to a cap that charges during the day then discharges through a joule ringer to shine a really bright light for a few hours at night. We want to sell them to support the manufacture of sove very advanced crystal cells and all the other folk building the bits along the way so we can build bigger and bigger and more and more through a coop. Dont you want to join in ?)
For goodness sake, have you figured out how to dampen that coil so it doesn't whine so loud? Great idea(s) you have, but for Pete's sake, it would probably behoove you to find a way to dampen that whine or give it a better mount >.< The second one you have is friggin nice, and QUIET! XD seems to be superior somehow, aside from maybe the resonance is not propagating through the coil and circuit. Really good ideas though for sustainable power for lighting, especially for solar/battery setups.
I figured out why the transformer does not work all the time when you disconnect the power. The transister acts like a mosfet it is stuck in one state so you have to ground it at the collector and then reapply the positive and its fixed.
Hi lasersaber, nice job. I have only one question please. volt-watt-type of bulbs used, gauge of winding wire and is transistor H1061 or 2n3055? thanks mnasim from Greece
Of course that is possible, but you need less, but thicker windings. The less windings, the higher the resonant frequency is, the thicker the windings, the less losses you get due to high current. well, doesn't mean, it will be simple. Never testet that for a Joule Ringer. Only SMPS Transformers.
are all those lights connected in parallel or series i can only get one to work when i connect another they are both dimme in brightness in fact the second one barely lights up so what causes that ? strange
Hi. Can you tell us how many winds in the secondary transformer coil? It seems a pretty good experience to reproduce at my home =). I was wondering if it could work with an old PC power supply transformer, replacing its coils for those you suggested. Cheers
To save our ears and SANITY, enamel the coils or place them in paraffin(candle) wax. I would use paraffin myself if the coils don't generate much heat, which I doubt they would. Also, try adjusting the frequency to get the highest output. Large transformers usually use enamel to keep the noise to a minimum. I would stick with paraffin unless you want to make it permanent since you can reuse and repair the coils much easier with wax. A heat gun will remove the wax if used carefully.
Hi Lasersaber! Thanks for your new vid and having succeed to make it very simple set :-bd For your next experiments like this, could you give an idea of the efficiency while making a comparison by measuring time discharge of the battery with indicating the energetic capacity of? Cause if not more efficient than bulbs according the the battery voltage, what would be the point? :/ To evaluate something always need comparison; isn't it? You should light 18V bulbs with 18V battery to compare...
1 question - are 2 ends of the wires which were wound underneath the secondary just left unconnected? It seems like 2 ends are open and left hanging. Is this right?
looking at it from a different perspective, let's say the ringing of the transformer is desirable for a moment, What can I do with this sound??? if you put on a dimer before the light bulb maybe a musical instrument can be fashioned a sort of theremin with nobs.
What type of bulb you used and what is it's volt & watt please? I am not an expert for JT but what I think if you put a resistor of 18k between base & collector, you do not need to tape it to start the circuit every time. Just an idea but may be I am wrong. Thanks in advance for your reply.
I noted that from the shared schematic its just two windings that are ratio'ed at 10:1 (200turns to 20 turns) which should maybe allow any 120v to 12v trafo to maybe be used without having to wind a ferrite? Anyone tried this? I'll be hitting the surplus electronics shops looking for some Ecores and bobbin this weekend to see if I can replicate and will share once I am able to get it done. Good stuff!
you say 200 turns on the output from the transformer for 110 volt CLF bulb i live in united kingdom as it 240 volt just wondering how many turns on the out from the transformer for UK ! think it would be some where around 500 turns ! and what TRANSISTOR your using !
The ultimate JR P3 The 2N3055 won’t work; it didn’t with me. If you’ve seen an Antenna’s cable, you know it has a copper wire, silver foil covering, and braided wire. What you need to do: solder one side of the copper wire onto the braided opposite side cable for the positive, connect the other copper wire to base with a resistor, the braided opposite side solder it to collector and then add a diode to it. This cable is the future; pass on info. Sorry, don’t get many characters to write on.
just use for dont nee the extra two wind one layer 20 turns in and out on the otherside than start another layer in and out as many layers as yoiu want trial and error but for best results double or triple the input use telehone cable it so god damn simple and dont make a mistake with the connection base and emitter base on the left and emmiter on the right otherwise you ll pop the npn 3055 like i did
