To save having to assemble the LED bulbs manually, maybe you could order flexible PCBs and have them pre-populated with surface mount LEDs, then you could just glue the flex PCB to a bulb shell. I love this idea so much, I've experimented with this kind of stuff myself and this is really beautifully executed. Well done!

rope handle that pole will kink . point of failure there id bet

is the bulb small enough to fit in a coke can then u can cut 1/2 out and u the can as a reflector fernel lenses on fle bay flat sheets

Fallt nicht auf den mist rein, er hat den looper extra so verändert das niemand mehr den richtigen hat. Ein Russe hat den looper gezeigt, lasersaber hat ihn gestohlen und verändert das er nicht mehr so ist wie er sein soll. #akula

From free energy to mainstream shit. Great work with the looper. You are the reason it will never come out. How many money did you get to buy your soul?

aren't those LEDs outdated in terms of lumen vs. amp draw?

It's been a while, very good. Thanks.

Do you ever do meetups Chattanooga Tennessee,?😊

The Man, the Myth and the paraglider Legend! 😊 That’s really good stuff right there. Excellent work! Thank you Lasersaber 🙏

Wow u are still here making things and making videos.😮

That is mind blowing

Really cool. Would be nice to be able to unfold the bulb into a different arrangent, focusing the light onto or away from particular areas.

4:22 remove this clip from what?

Singing coil problem? Saturate winding with super glue.

a.m.a.z.i.n.g............thx........😊😊😊👍👍👍

whats the job of the pot core in this circuit?

A winding mechanism would be better then a pull rope!!! 💡💡💡

Very cool Laser Saber! I remember many years ago making my first and only Joule Thief circuit. I didn't have a ferrite core, so I just used some iron wire wrapped around a rubber grommet. The odd thing about it was that it did not work with the resistor in the circuit, but it did work without the resistor.

Really interesting project, great potential for a work site light. But word of caution if your running the LED's direct off of AC I have been totally messed up ill (motion sickness style nearly vomiting in the end) from working by an LED torch late through the night once, although I haven't thoroughly tested it I put that down to a very noisy AC circuit even if it was just off qn 18v battery and even if you can't directly see a flicker I now believe it can affect people. I'm not someone who particularly notices any of the grid AC LED bulbs now but whatever frequency the torch was running at messed me up. So my suggestion is even if you have to sacrifice efficiency some strong filtering should be looked at trying to run as close to DC as possible. Or get a good sample of people to see if uou can nail down any "bad" frequencies.

I had the idea of a pullstart powered compressor for a pellet rifle awhile back. I like your idea more. Ever since playing Myst several decades ago I have been obsessed with dynamos. I have several flashlights powered by various types of generators and I think your approach is the best. I have thought of using voltage regulators to pull more power from the battery/capacitors, but your approach of using high voltage is amazing. Because when you turn a generator very fast you get more voltage, but not more amperage, so normally that extra voltage would go to waste. This setup lets you store all the energy, and regulate it down to a useable amount. I love every part of this. Good job!

Yourself and Styropyro should collab on something .

Have you thought about contacting PCBway to act as a sponsor for the LED set ups? This could save you a lot of work.

You always do great work. Glad to see your still at it.

Are those LEDs very special? How about buying and repurposing a commercial COB LED or even a LED strip? Thanks for the video!

Well done !

Great to see you back. One tip you should use a brushless motor with three phase rectifier! Just find the right size motor like a 100kv RC motor or lawn bl motor.Then will have more charging and less work to charge it.

Use it to trickle charge a larger battery.

needs a diffuser for the light or use diffused LEDs

Usb charger in the base for charging cell phones?

When disconnecting the power from the transistor's you got more power out than you put in? Sounds right to me😂 but be careful those people that discovered this kind of stuff have a tendency to disappear for some reason.

That's pretty awesome, would love to see a Leg version of this, legs have way more power, so more hours for less effort

7:23 ... Super cap...

Glad to see you back with your amazing project that you kindly share! Sharing is caring! Thank you man!

Congratulations! :)

You could try using higher voltage LED, they are just single 3.6V chips strung in series so no need to do all that soldering. I have used Lumileds Luxeon 5050 smd case size LEDs in some projects because of their efficiency. Some models are rated at 170lm/watt under normal use and if you under drive them you will easily get more than 200lm/watt. Also, Google seach "philips dubai lamp" to see what they did there - also under driving LED "filaments" to get great efficiency.

Brilliant! 😊👍

Put a flywheel on the generator. Also aliexpress sells these with a hand crank.

The invasion here is mostly the high voltage running an efficient voltage regulator. I'd personally use a cob led element from existing bulbs..

trash video and click bait title. "doesnt use batteries, charges in seconds" what the hell do you think you are charging? the led's?

Love this guy

This could make a serious difference in 3rd world countries. Love the circuit!! Clever

Is the sound produced by the core produce a consistent tone?

It is not really the "World's First Pull Start Lamp". In the Netherlands, we have the "knijpkat", a light that not need a battery. See: en.wikipedia.org/wiki/Mechanically_powered_flashlight

Some feedback for the bulb it self is maybe stagger the rows of leds for a more even coverage around with the focused bulbs. Other wise fantastic project you have!

@lasersaber - Great build, I particularly like the telescopic extender. 👍 Have you considered spiralling a length of self-adhesive LED ribbon around the head? Ribbon LED's would certainly spread a more even light than individual LED's. With ribbon LED's you would also have the benefit of an IR remote control and essential IP rating for outside use. If you wanted to take it one step further, add a 3D printed cage around the LED head and include a bug zapper! ⚡ This is just my opinion, I could be wrong. 😉

Great concept, now reprint the led holder bit and offset the led's so that their light throw patterns overlap. It's the dark spots that make this device aper less capable than it actually is. This will greatly improve your device. I'll be watching for the production model. I'll buy a few.

This is wicked. I remember in Army cadets some of the guys would bring those wind up torches that they would lose interest in because they had to give them a spin every 15 mins or less. I wouldn't mind seeing this SJR system in more of a compact torch size, much like a dolphin torch but maybe the size of a car battery.

Can you provide an Amazon link for the small capacitor use in here. Thanks

I wonder what this would be like with those LED filaments.

huh so its the transistor, I have noticed this happening a lot in my build ( 4:30 ), thank you. Good to see some more builds from you mate. Keep on rockin.
