Reply James Fraser on June 8, 2014 at 8:18 am Nice one Lasersaber! I’ve been refreshing your site anxiously over the last few days after I saw your latest video on YT. I’ve tried similar JR circuits with some twists of my own but have only achieved brightish runtimes of around an hour and a half. This is exciting progress. Well done! Reply Yves on June 8, 2014 at 12:27 pm Hi, great job, continue. What is the size for the litx wire ? Reply Mike Poirier on June 8, 2014 at 12:54 pm Very nice work. Thanks for sharing this this beautiful discovery. It is a useful device. Mike Reply peter on June 8, 2014 at 1:47 pm are you gonna sell kits of this? Reply Bill on June 8, 2014 at 8:45 pm Assuming that the oscillator operates well below a frequency where skin effect would make an appearance, what difference does Litz wire make? Reply Keepitsimple on June 8, 2014 at 9:04 pm You have inspired me! Can you recommend a beginners book or web site for basic electric and electronics? Thanks, Keepitsimple Reply d3x0r on June 8, 2014 at 9:46 pm One other minor question; is the 200 turns the first or second winding? The diameter changes a lot, making the inductance quite different depending on ordering… Reply murray on June 9, 2014 at 12:57 pm Hi Lasersaber In the previous video you mentioned that you were using the 3rd winding on your pot core , I don’t see this in use in the posted circuit V3 , is this no longer needed now you are using litz wire ? Thanks Reply murray on June 9, 2014 at 2:42 pm Hi Lasersaber , as the coil seems to be the most important piece here would you mind giving us some more info on the latest core you are using , are you using 7 Strands of 0.04mm litz at 200 turns and 100 turns without the copper foil, or is this info for the last coil video? in the last video you said you are now using the third winding but i don’t see that in the latest circuit diagram . Thanks for giving us so much info and keeping this as open source . Reply desmond verlaque on June 10, 2014 at 1:43 am hi mate super doper job..thanks tons for these great inventions.. I have an improvement on the shacking magnet generator..just get in contact with me and I will send you the info.. keep up the great work.. regards SEYCHELLES Reply Wistiti on June 10, 2014 at 2:27 am Next step, loop with a solar panel!!! 🙂 Thank you! Reply Dan G on June 10, 2014 at 5:05 pm Are you sure of your schematic? I don’t quite get how you get current flow thru your transformer winding to light the LED’s with DC. Guess I need to build one myself! Thanks. Reply dan g on June 10, 2014 at 5:19 pm So, your using the MPSa18 as a very simple oscillator/ multivibrator circuit? Very nice. Have you ever put a scope on the cap or the diodes to see what the waveform is? What is your source for the litz wire you mentioned? Thanks. Reply d3x0r on June 10, 2014 at 9:15 pm https://www.youtube.com/watch?v=8mJX5qW4ghk (scope of a different version basically the same) The schematic is correct. The first pulse relies on a capacitance of the transistor to get a short pulse (primary charging). which is enough to cause the base to trigger and repeat the cycle. http://www.overunity.com/14591/lasersaber-strikes-again-a-joule-thief-king/#.U5d1avmwLPw Reply 4Tesla on June 11, 2014 at 3:36 am Hi, Great work!! Why not try to run with crystal power cell? I bet it would work great as you don’t need much power for the circuit. Reply Andrea on June 11, 2014 at 8:07 am You have regained the confidence of the people as they had published a false invention that the free energy with the transistor soldered in https://www.youtube.com/watch?v=2Lmh4X6hiSo. I hope that you will not do stupid things like that still only lead to ruin all the works you’ve done. Reply paul on June 11, 2014 at 10:15 am I don’t have a mpsa18 but to get a longer run time i put the 10M at the end of the l2 coil and used l3 from emitter to negative of The cap. l3 will only work one way Reply Alf on June 12, 2014 at 3:16 pm Hi Lasersaber! Great work, and great that you share all your infos with the world. I have tried one of your JouleRingers 1.5 years ago – and it worked after some small changes. But this version seems to be something really efficient. Congratulation. Do you sell coils for SJR or do you sell an “easy to understand plan” how to make a working and efficient coil? Thank´s in advance. Alf Reply Fueltroll on June 15, 2014 at 1:22 am Would it be possible to build this thing so, that the cap is feeding himself ? if you sell kits of SJRs, contact me Germany Reply Jose Henrique on June 15, 2014 at 9:51 pm I Lasersaber,i love your work you have done so far ,i`m a huge fan Please be more specific about the coil , for me to replicate thank you Reply Joe on June 16, 2014 at 8:43 pm Have you been bought out by a saudi research group yet? Looking forward to a scaled up design!! Reply Bill Dempsey on June 18, 2014 at 4:40 pm Do you have a link for the coil you used? Or did you make that one yourself? If you made it, which video has the instructions. I’m interested in duplicating your experiment and fiddling with it a bit. Thanks for a great blog. This is my favorite of all my subscriptions. Reply martin on June 19, 2014 at 9:49 am really just wanted to say hello and keep up the good work. but please update the schematic to include the 3rd wire and please excuse me if im wrong but isnt there some sort of foil too? thanks laser. -martin Reply showtime33 on June 23, 2014 at 5:15 pm Did you say third coil? Sorry another request for a more detailed schematic. Incredible work and thank you for sharing! Reply Alejandro on June 25, 2014 at 10:54 pm Funciona mejor si la base del transistor se conecta entre medio de dos leds. It works best if the base of the transistor is connected between means of two LEDs. Reply d3x0r on June 26, 2014 at 12:55 am Depends on the LEDs. I have 5 Red LEDs that work entirely differently than 2 Blue… and I just got some of the same whites that LS uses, and I dunno 2 or 5 is about the same… the blues that I have are extra resistive… Depende de los LEDs. Tengo 5 LEDs rojos que funcionan de forma completamente diferente de 2 Azul … y acabo de recibir algunos de los mismos blancos que LS usos, y no sé 2 o 5 se trata de los mismos … la tristeza que tengo son de resistencia adicional Reply JonnyB on June 26, 2014 at 2:45 pm Litz wire reduces the resistance due to the massive parallel paths the current takes. Plus there is a capacitive element due to the same parallel wires and each having a different resistance causes additional capacitance, or inertia imparted to impulses, the wire has. You could think of it like those new expandable water hoses they sell in a simpler analogy. If we go with this analogy then this is like a bagpipe type system with inertia thrown in like Tesla was saying. The pressurization of the capacitance is what keeps this running. As long as you don’t loose energy then this system could run indefinitely. Try using the static shielding Tesla was working with. He has a patent for it, Ref: http://www.teslauniverse.com/nikola-tesla-patents-514,167-electrical-conductor Look for Figure 2. He has an improved cap as well to better facilitate the container to pressurize here Ref: http://www.teslauniverse.com/nikola-tesla-patents-567,818-electrical-condenser Again figure 2 built with oil dielectric should suffice. Reply Alejandro on June 28, 2014 at 2:10 am Usa leds de aparatos viejos. Reply Teo Graca on July 15, 2014 at 11:08 am The circuit looks fairly unique. Thanks for sharing! Reply JA Loken on August 25, 2014 at 4:13 am Hi! Thank you for sharing you hard work with us. Can you please tell me what size # of wires and toroid you use. Thank you very much! Reply Alex on September 28, 2014 at 3:26 pm Thank you so much for sharing. Very very good experience. I have one question. what s gauge about coil ? AWG ? Where is end et start of coil ? Thank you so much Best regards Alex Reply Alex on October 25, 2014 at 12:43 pm Hello I have not register me on the forum because the are a problem in a register page so I break the issue here. Where are you find the plastic pot of the core P? Thank you so much for your answere best regards Reply Mort on November 2, 2014 at 3:20 pm Can you tell me more about the capacitors used in your boost pack video? What value are they? Where did you find them for $6. ? Any help would be appreciated. Mort Reply Fanie on December 19, 2014 at 11:16 pm I was wondering if you up the scale of this how much longer the kid’s solar car would run off the battery… Reply Mike on January 1, 2015 at 6:19 am So many comments, and there’s no info about coil and wire AWG… so sad. Feel that is some top secret technology. Reply Bill Dempsey on January 1, 2015 at 3:43 pm I believe he made an entire video on how to wind the coil. Check his video list. Reply Travbm on January 27, 2015 at 8:00 pm Does it work with a crystal cell? Reply KaiLan on February 9, 2015 at 5:19 pm hello it really works and how long and ferrite core is or just Reply sawsaw on June 29, 2015 at 2:35 am self pulse battery charging may be possible. Reply Robert on July 11, 2016 at 1:48 pm Hi, Has this become a commercial product already? Reply TuggyNE on July 12, 2016 at 8:15 pm Yes, it has.
