Pirate's Lidmotor Jeanna Light Joule Thief Replication.wmv

[tculhane]

Hi Pirate! I am inspired by your ending comment "everyone should try to make one of these because I think they're great" and am trying to figure out how so that I can take the know-how with me to Africa and the Middle East where I work with the urban and rural poor to achieve our Millenium Development goals. If we can get everyone in the "third world" to make one of these we can alleviate a lot of suffering. Problem now is finding the ferrite cores. Any further ideas? Can we use square cores?

@tculhane

Thanks. This video is old, check out my latest vids using a modified Fuji JT and edison based LED bulbs. Much more light and easier to build using more readily available components.

@Pirate88179 Thanks! I have been watching your FUJI camera vids and when I get to the US this week I will buy several disposable cameras and follow what you have shown. The next trick will be replicating the FUJi circuit with scavenged parts in places where they don't have these disposable cameras. If you have any ideas of how to do that we would be much obliged!

[ekremgusani]

can you make tutorial step by step for begginers PLEASE?

[Pirate88179]

@ekremgusani

As it says in the video description, everything you need to build this is over at Overunitydotcom. Use a "." instead of "dot". Also, check out Lidmotor's videos on this circuit.

@ 1:04 , no , when you open it everyone will go BOMB !!!! AHHH! BOMB !!!

[ibpointless2]

where do you get those big toroids?

[Pirate88179]

@ibpointless2

Good question. They used to be available surplus from like All Electronics or Electronic Goldmine (I forget which) but when they sold out, we have had a tough time finding them. Jeanna has reproduced her circuit using a smaller, easier to find toroid from electronics goldmine and it works very well. I was only able to obtain 4 of these. A few places still sell them if you use Google but they want like $50 US each! These used to cost about $2 US surplus.

Love it Bill! Great Job :)

[Pirate88179]

Thanks.

Bill

[Lidmotor]

Great!! Looks good. I like the additions especially the larger battery and magnetic battery clips. I started using that method yesterday. It is another simple solution that works. Thanks. I have seen it before but I just got around to trying it, Kooler was using it in his video also. This sharing of ideas really helps.

[Pirate88179]

Lid:

Thanks man. I was basically just copying your and Jeanna's work. Yes, the sharing of all of this information and people's creative ideas is fantastic. I have learned a lot from you and others and I appreciate it very much.

Thanks,

Bil

[trance183]

I have been using neo magnets as battery clips for a while now but I wanna know if your magnet lost any strength by soldering? I heard high heat can pretty much destroy a magnet. Did you solder directly onto the magnet?

[Pirate88179]

Very good question! Yes, when you solder, if you get near the Currie temp of the mag. it goes away.

Here is what I do. I solder the neo as cold as I can. But when I check it, the power is almost gone. So, I take another neo and it still attracts to the soldered one and I hot glue it to that one. No glue in between just on the edges. Now i have a neo connector full strength.

Very good question.

Bill

[trance183]

Thanks for another great reply Pirate. Thats a very good idea. Hmm. I'm thinking about using a small washer to solder the wire to, then I'll attack a small neo to the washer. I'll get back to you if I get good results. Thanks again. Your videos are inspiring.

[Pirate88179]

Thanks, I appreciate that.

Bill

[tectalabyss]

Way to Go ! Thanks for sharing. Tec

[muddymuddymuddmann]

thanks Bill, I'll take three for christmas.

I like the workmanship.

nice layout, and nostalgic look.

MUDDy

[Pirate88179]

Thanks Mudd! Actually, my workmanship was a bit on the crude side but hey, at least everything fit in the box when I was done, ha ha.

Bill

[muddymuddymuddmann]

I have an old one tube regenerative antique radio that uses 2 different battery voltages at the same time for the tube. it looks like you light except for the light. LOL I bet that light would mess up radio signals real good.

MUDDy

[jonnydavro]

Real Nice Bill.This is a realy usable device and Built to your usual high standard.I find it remarkable that a 1.5v battery can do this.Great work .regards jonny

[Pirate88179]

Thanks Jonny!

It is remarkable what 1.5 volts can do these days. I just wish I had thought of it. Hey, I could probably squeeze my SEC-18-1 into the box...I wonder what that would do?, ha ha.

Bill

[d3adp001]

run time? and light output in CP or lux, or lumens?

[Pirate88179]

Good questions all. Lidmotor has been able to run his for 36 hours on a single AA. I am using a C to get even longer run time, when the light goes out, I will let everyone know. I have no easy way of measuring the light output at this time.

Bill

[stevesrd]

kool,,so many possibilities..

[Pirate88179]

Thank you. Yes the possibilities are many indeed.

Bill

[4CHRISTONLY1]

Nice Bill . I am going to make one but my bulb will be enclosed in a small globe in case it gets tapped The break easily

[Pirate88179]

Thank you. That is a good idea as they can break easily and then you have mercury to deal with. I should probably look into an enclosure as well.

Bill

[jeannacav]

That is a beautiful jeanna's light lamp Bill.

Your frequency is very interesting. Mine gets louder and more audible when I have the rheostat open. My frequency must start out lower than yours.

I agree. Everyone should make one of these.

They are great light and so easy to use... just flip the switch.

Great job,

jeanna

[Pirate88179]

Jeanna:

Thank you. This is a great circuit you have come up with. About my rheostat, even though it is 20 ohms, I need to have it about 90% open or I get no light. Right now, I just leave it open all the way but I need to make some winding adjustments I think. It does not work as it should right now.

Bill

[jeannacav]

I had that with the 20w bulb but not with the 10w.

Your frequency is high which means to me that since it is a joule thief the voltage is lower. this is something that will teach us more. Please pursue this.

If you wrap 10 turns around the toroid how many volts do you count on your scope? Can you light 4 leds in series from that or 3? ... or less? j

[koolerization]

i like the box deal..

you can hear a screaming inside saying

let me out ahhhhhh..

i like the double stack toroids ideal...

[Pirate88179]

Thanks. I believe Lidmotor was the one with the box idea on this project. I think the double stacked toroids will give me more output but I need to do some more tuning to take advantage of that. I may need to add or subtract a few primary windings to optimize it.

Bill

[marthale7]

I love neos for battery connectors. I used them yesterday for batteries that don't have terminals. great for bypassing the other leads and getting right to the battery.

[Pirate88179]

Yes, I must have seen this idea somewhere before and it does work great! Kind of a universal connector for any size battery, except, I do have one AA made in China that they will not hold to at all...it must not have steel or iron on the end caps.

Bill

[JavaLessons]

Great.

If you have pets, how do they respond to it, if at all ?

[Pirate88179]

I have a cat that does not seem to even know it is there. I had wondered about that too.

Thanks,

Bill
