Tesla Torch Flashlight Prototypes for Sale + How to Wind the SJR L Coil

[@greenmanotg6056]

I've been a big fan of yours ever since I stumbled across one of your vids over a year ago. I can't express my gratitude for posting all the stuff you do, really awesome. I've been working on a couple of projects based on your vids. Thanx again.

[@electronicsNmore]

Nice flashlights, but how do these differ from other shake lights/crank gen's that have been around for a while now? Your also using super caps to store the higher voltage charge, correct?

[@TheBdd4]

Great project Lasersaber. One suggestion, for those who want to experiment with your circuit, I suggest the addition of a fixed value resistor in series with your 1- 10 meg pot to prevent someone from adjusting the pot to 0 ohms and applying all of the capacitor voltage across the emitter to base junction which will smoke the transistor. y the way, in which of your videos do the parrots star? I have never seen them.

[@hoptoads]

Excellent work Lasersaber.!

[@mdcplas]

I have been thinking about your shaking flash light. Have you thought about putting a copper spring in the base and top so it will bounce on it's own with your initial shake.

[@drusha]

Hi Lasersaber. I've tried to build your most recent version of SJR and got 11 minutes of LED glowing on 2200 uF cap (charged to 9V). I've also used much bigger resistance for the feedback - 60 MOhm to maintain lower frequency of the ringer (2 KHz), then it sustains longer LED glow. My transistor is exactly the same as yours, but the coil is toroidal. My question is: is it really so crucial to use the pot ferrite for the coil? Thank you and keep up your good work!

[@hammysmad]

You`re a genius and a nice one to boot. Good on you laseraber.

[@propableself944]

the bobbin you are using has approximately the dimension of this small sewing-machine-bobbins that are meant to be inserted under the needle in the body of the machine

[@Zinxen92]

Laser, everything you do is awesome! That is all.

[@jonathanyonetani8230]

Lasersaber, first off thanks for the work your doing and sharing. Secondly, my affiliate marketing knowledge is at your disposal.

[@valveman12]

Lasersaber are you just using the Bobbin without the ferrite shell? Just to confirm, is the primary 20 turns of #22 wire and secondary 40 turns #22 wire?

[@Kntryhart]

Impressive! Just a suggestion...add an opening for a lanyard. Good luck!

[@lasersaber]

I love that idea! Now I will have to rework the 3D model again. :-)

[@Kntryhart]

lasersaber LOL...if its like any of my projects, just when you think it is all done, another idea pops up! Keep truckin'...

[@Candyman97]

lasersaber And the next word after that is Damn!! lol

[@oudotcom]

By the way, what are the names of your 2 nice parrots ? Do you let them fly in your big workshop garage ? Love those birds ! ;)

[@lasersaber]

Their names are Boo and Lucky. The do fly around the house sometimes. I will feature them more fully in a future video.

[@Justin-hm4xu]

lasersaber you should realy make a how to im only 13 and am interested in your design and i want to be a electronic engineering when im older

[@naokikashima9349]

lasersaber Lasersaber I don't get it, you didn't use Litz Wire or Foil layers in the making of your coil in this video! Are those things NOT needed? Please respond when you can. Awesome work on the Tesla Torch by the way.

[@AHN1444]

can the Joule ringer circuit power a motor?? instead of leds?

[@seanhogan5984]

Instead of having switch try hooking up two wires in parrellel to the potentiometer and make a small foil pad on the body of the case so when you press down the harder the brighter it gets, or just to use up the excess juice in the caps.

[@lasersaber]

I love that idea. I will try that out tonight. I have three more prototypes almost finished up. I am working on increasing run-time.

[@oudotcom]

Well done ! Did you make the handcrank generator also yourself or did you buy this ?

[@lasersaber]

I am buying the hand crank units as ready made modules. I am working on finding the best source for them now.

[@jackp6]

i was thinking at the mechanical "knijpkat" (if we call it in Dutch) at your first prototype maybe the "knijp" (i guess it is translated press or squeeze?) mechanism is a better option then the wind option...

[@lasersaber]

I will be testing everything. Thanks for the suggestion.

[@3zdayz]

if you put a low own resistor inline, a scope across that can indicate the current flow (E=IR... I=E/R so the voltage relates as current detail of values doesn't matter), which might be more detail(higher deltas) than the measurement across the cap itself.... actually for micoramps it would be better to use a larger resistor so the V can be proporiatnly bigger.. probably 100 ohms at least,...

[@TheBdd4]

Good idea to use a low resistance resistor in series with the voltage source. I suggest 0.1 ohms. I measure the voltage developed across that resistor with a 5 1/2 digit multimeter and multiply the results by 10. Five milliamps drops just 500 microamps across that resistor. I solder a dedicated set of test leads into the circuit I am measuring to minimize voltage drops due to high contact resistances.

[@TheBdd4]

TheBdd4 Correction: 5 milliamps drops just 500 microvolts across the resistor.

[@3zdayz]

TheBdd4 right; but the circuit is in microamps so maybe 500uA. you'd only see 50 microvolts... if you go higher 500uA would look like 50mV with 100 ohms...

[@Subcoder]

So, no teslatorch.com?

[@JaysNotebook]

How long will 3 seconds of winding run the light for? Thanks!

[@sk8pkl]

wow thankyou lasersaber!!! your the best!!!

[@russb2945]

Could these devices be incorporated into the flying of a copter with say 5 props producing constant power by spinning, or just moving and feeding back into a cap bank for unending charging and unending flight.....?

[@Kurzschluss480Volt]

Hi, i've tried to wind this coil with 0.5mm magnet wire with 20 and 40 turns like in the video. And then i've tested with the your SJR L Tesla Torch circuit. It's not working. The Led won't light up. The transitor that i use is a MPSA-06 The cap has 10000uF/10V. I've flipped the coil connections. No success. Any idea? Maybe you could help me. Maybe my coil won't work. I use18/11mm potcores. Do you sell those coils too? Do you have winding tips for me? Thanks and best regards, Mike

[@ozzyyzzo929]

my grama has one of the wined up led flashlight like that

[@joohop]

hi ya bud how much for just the kit with no case ?

[@humanx187]

I want to get started in doing what you do. What did you go to school for or what exactly would be your title?

[@stevenfox2172]

Born Leader - Inspiration - G#d

[@drjoeg]

How many crystal power cells would it take to power a fluorescent light of 500 watts AC using an inverter? Thanks!

[@Coolnventions]

how long does it last? I may want to invest

[@anivinvinod]

Very very promising and interesting ...Mr.lasersaber sir ...ur using dc impulses to the best limit ...... but instead of powering only leds ...sir try powering some other items such as motors , powering a tazer with this would be mind blowing ..... and one more thing , try converting the voltages to amps by using inverters and then run some normal appliances , same said to crystal power cells .... they don't die out completely ... even after prolong usage ,... but amps are tiny .... but why can't voltages be converted to Amperes ....sir you please might want to try that out .

[@googletropcurieux8670]

wow i like the website! it's a nice idea you should continue imo tc!

[@Samrules888]

have you possibly thought of making a sjr looper powered laptop phone tablet charger?

[@lasersaber]

Yes, but those ideas are very experimental. You do not want to damage your electronics with high voltage spikes.

[@peakopore8433]

lasersaber Use the light to charge solar cell (like your SOLN1, but smaller). Could 3D print a cover/cap for the light that has a small SOLN1 inside. That way you could use as flashlight or charger.

[@Samrules888]

PeakOpore solar cells have only 20% efficiency. the efficiency of the sjr looper otho borders on wizardry. there may be other ways to mediate voltage spikes. use the sjr to charge an external battery pack?

[@6969smurfy]

***** what u takin bout Willis?

[@Samrules888]

***** popular mechanics always publishes crazy ass shit like that even if it's purely theoretical and has no prototype.

[@Candyman97]

Frickin' amazing!! I think you have the right idea on funding! Plus if you ended up having to make thousands of these, it would probably take the joy out of it for you!

[@BinjKomisar11]

Hey Laser-Saber. Thanks for showing the light. I tried about 5 different winding ratios with the 3.0 schematic to no avail. Looks like I was going over-kill. Anyways thanks again, Peace. (If I can get the useable light to increase from my crystal power cell I willl make a vid, but we shall see) :)

[@lasersaber]

I will be watching for the video. I was planning on making a Crystal Cell version of the Tesla Torch as well. The winding ratios may need to be different as the cells voltage will be around 1.5V, or maybe I will connect 10 cells in series.

[@BinjKomisar11]

lasersaber Yeah, I think a few in series would be best... but there really is only one to find out :) I am going to take another crack at this circuit tonight and hopefully the results will be positive.... We should talk on G+ sometime, I would like to tell/show you what I have going on, you may just find it interesting. Peace. B

[@stevenfox2172]

Did you crack the whip?

[@Vinnay94]

Since Tesla Coils produce wireless Electricity, you could use Multiple Bulbs Incandescent and/or LED bulbs easily since you don't need to wire them.

[@propableself944]

I hope that you are not buying into the common practice of sealing and glueing the cases up and that everything stays repairable and accessible. Looks good although the cases are a bit chunky for smaller hands. Rounded Ribs or Indentations would compensate that a bit. An eye to attache a bit of cordage would also improve the handling a bit i think.

[@julijanniko]

I think that this could be great light for bicycle. You should try to build one.

[@jerobarraco]

You're awesome! I admire you and your work. I love that you like to share your creations too. I would suggest you to make a patreon account. it really takes no time and i think ill suit you perfectly. that way you could fund all your experiments (and maybe consider releasing them under creative commons or open hardware). peace!

[@StirlingLighthouse]

Nicely conceived! An On/Off switch would be handy.

[@lasersaber]

What do you all think, should I add an on/off switch? I thought it would just be another part that could break and it charges so fast that storing charge is a non-issue. If you do not want to see the light you can set it down vertically over the LEDs or put it in your pocket. I am willing to add a switch if a majority of people think that it is a good idea. Let me know what you would prefer. This is now the official "should I add a switch?" poll :-)

[@toddpacman1881]

Yup, on/off

[@nelsondisalvatore9812]

what happen to the soln1???

[@stevenfox2172]

Did these products make a profit?

[@Rubberband54]

L O L .. Void-Hawk Flashlight ad running before your Video

[@Thescatteredprepper]

Maybe you could ad a clip to one side.

[@shad0wburn3d]

Always impressive work! Will check out the sites. Cheers.

[@Edmorbus]

Thanks for sharing

[@spencezar666]

you might want a switch to turn it off so you dont put unnecessary strain on the parts

[@InvalidMemberAccount]

oh here, let me set all my stuff down, here in the dark, while I crank this. just a minute, I need to take my mittens off....

[@MrMawnster]

how is this wind up flashlight unique?? Or is just the marketing going to be the unique part.

[@ivanjacob_]

Because it only takes 3 seconds to charge it.

[@Aquar1uZ]

Extremely low current draw - special Joule thief type circuit and coil. Instant full charge that lasts. Need I go on?

[@VideoVegetable]

Congrats lasersaber. Guess you can quit your day job now! One request; Can you build a better cheaper electric car next? ;)

[@lasersaber]

***** The "Tesla Releases Patents" news headline made my day. Now I just hope other companies will see the light a follow their example. I have been saying for years that open source will win out over the current patent system.

[@lasersaber]

@VideoVegetable I would have quit my day job years ago if it was not for the fact that I love the work that I do at my day job. It is fun, challenging work with a great team of guys. I will continue to work on these projects as my side hobby. I do plan on adding some local partners who can work on these projects full time as becomes necessary. Someday I do want to try building an electric car.

[@calthmlikiseethm704]

Not new been done...

[@InvalidMemberAccount]

SHAKING TAKES ONE HAND !!!!!!!!!!!!

[@joelaalanizful]

Instead of a handle, try a wheel... :D ...Trust me, just try it... ...I will most definitely last longer than the handle mechanism! ;)

[@lasersaber]

I may try that. If you pushed the wheel along a surface it would charge the light. That might work great!

[@iwillhelpyouout69]

$247.50 is not parts cost like you claim in the video. Look at your ebay ad.

[@aerotro]

You might want to get some KAPTON tape it is what is used my transformer manufacturers between winding layers www.ebay.co.uk/itm/4mm-High-Temperature-Heat-Resistant-Polyimide-Kapton-BGA-Tape-silicone-adhesive-/291141173268?pt=LH_DefaultDomain_3&hash=item43c95dc014
