986 Making The Joule Thief 

Glad you mentioned him! ..... I thought it was his article in EE that kicked it all off (but I was obviously wrong)

Rimstar Org is where i first learnt it

cheers mate

cheers mate - they are pretty interesting circuits that's for sure

that is an awesome post mate and thanks for writing it - I totally agree with your sentiments here

lol - I do like it strong - cheers mate

yep you are absolutely right but that's not the point here - quite a few folks have problems getting it to work at all and even more believe they have to replicate exactly - which is just not right in my mind

@@ThinkingandTinkering true enough. Making it accessible to everyone is definitely the first hurdle.👍

@@ThinkingandTinkering go rob you statment is so true your boy is getting the hang of this youtube stuff also

@@brandonboulton2776 cheers mate - I really agree with that

@@ambersmith6517 lol - isn't he though - I was pretty impressed by his last video - he is most definitely getting there lol

I use it for peltier powered LED's. When using only body heat the voltage produced is too low for even Joule thiefs using typical silicon transistors to work. Vintage germanium transistors can boost from as low as 0.1V.

There's a lot of nice optimizations, like instead of having the output of the LED go to ground, send it to the source. It is then at higher voltage than the source so it will go right back into the circuit.

Thank you kindly!

wow - cheers ate and thank you for taking the time to post

Glad you enjoyed it

ah well you get five days of concentration mate! - always a bright side lol

it's a stepping stone

.....the use of relays along those lines were called vibrator circuits rather than oscillator circuits . I remember the valve radios in cars required vibrator step up of voltage to operate the valves. I remember a project in our Australia Electronics magazine for replacing your vibrator circuit with a power transistor circuit . It's topsy turvy if you think it all through. I perceived the Japanese as being the first to introduce solid state car radios . In that period solid state meant semiconductor design cos it didn't have glass components. .Today solid state essentially means the contrary ie - use of glass , well as the electrolyte/separator material in the modern lithium batteries anyway ...

@@charlesdickens6706 Yes. It figures is is not an original idea though i did not know about these. I guess you're a bit older than I am. 54 ... Thanks for commenting.

hans is talking getting parts out of "junk" charles is from australia and old school these things are close to my heart some of those ozzys are just incredable "warpspeed poida mark wiseguy mack to name a few " any one who knows where to get parts has gained wisdom along the way if you guys ever post some where like thebackshed or any where else please let me know i would enjoy reading your thoughts on any subject this is especially true with the older generation we lose more every day of the ones with only comes from a life time of living wisdom back then when you was owed nothing and your word was truth if you didnt like something you rolled up you sleeves it once was known that bitching fixed nothing you know the ones that built and died for the things we take for granted we think our selfs smarter yet these things are not maintained we let them be taken little by little back then they knew freedom was providing every thing for yourself what you could not provide the community came together locally other things god would make a way threw a good freind neighbor or a church it would private no one would no and next time you would be that one keeping it to yourself no need for a big way to big den of vipers telling you how to live and robing you with out you realizing it there was some bad people that didnt see those words in the book of good news and truth clearly saying we are all equal one of the being done wrong warned that if you allow these horrible thing next it will be you pure wisdom now it is all of us just not as bad in some ways back then they new if you let things to be provided for them then the same gains control and freedom is lost having a business in a town was a privilege given from the people back then they knew latest new things dont bring happyness they knew to walk softly but carry a big stick they knew right from wrong and new life was a blessing they new what the new sears roebuck catalog coming in the mail was good for they new it was wrong to hate others you dont see eye to eye with they prayed for and helped people they didnt agree with they knew all peoply have right not given there creator not gov them bad people in town was the ones that didnt care if everyone knew they smoked some herb and got a little rowdy after drinking white lightning on the weekends they knew that god bible roof plenty food a loving family good friends helping others in need and freedom was the things that was good and brought happyness they opened doors for said yes mam to knew women where diff from man not unequal to they had the most important job there ever was or ever will be that few or no man can do a women was to be put on a petestal appreciated loved and treasured we have very little happyness always bussy and are good at complaining we have no answers and the older generation has no purpose in nursing homes they go we are to bussy they have nothing of value to add our problems are new nothing like they lived threw i know most will not give them the time of day there are a few that are not completely blind like myself i see well enough to know i cant see nothing i am ranting about myself by the way i never see until its to late i can see my grandpaw shaking his head say there is no use get a big smile and tell a joke to quikly change the subject some saying are just truth the only thing we learn from history is we learn nothing from history tell me how we are better off sorry for rant rob is trying to teach how to learn and encourage and this downer dont belong here but i guess that is way it is called a rant sorry to all offended

..... An AM radio is actually an essential tool when working with a variety of electronic equipment. I first used one to do the ignition timing for the earlier Kettering ignition cars . Later along with the FM the radio was useful for RC model hobbies for gauging faults in transmitters . ...... ...

Glad you enjoyed it

they would light up and rectify

@@ThinkingandTinkering and you would probably drop a few bolts right but it does that anyways doesn't it

.......essentially the magnetic field might require say ½ a millisecond to build up to full strength. However when disconnected from the power the field collapses much quicker ,say ½ a micro second , that's a thousand times faster to unload all that energy than it built up under say 12 volts potential. Conservation of energy means it unloads at a thousand times increased voltage if energy remains constant ideally. Nothing is ideal so it'll result in maybe around 400 volts resulting from the initial 12 volts applied ( maybe the collapse is 10 microseconds duration , I was guessing ). This used to happen in the primary windings of old Kettering ignition automotive coils, then that 400 volts would be stepped up to 30k volts by the secondary of the coils (they are transformers ). As for modern cars, I'm just not up to speed.and the wiring diagrams are not useful . I'd guess modern cars are along the lines of cdi .

no such thing as etectrons my friend try looking at it like this magnetism amps is same thing everything wants to be equal with everything around it the magnetism want to be equal with the things around it it will leak out with the path of least resistants the mor turns on output the more paths the votage is the speed of the magnetism leaking out on the input coil batt side the path of least resistants is into the core intill it is full when core is full if out put coil not hooked into anything the coil can not leak the magnetisom out so the input coil heating up is path of least resistance we call that a short i hope this has helped some one i am horrable at explaining things but so many closed doors will open when you think like i tryed to explain instead of in sothing that dont exist

@@ambersmith6517 I've never heard such things in chemistry, small engines, or any other science classes in school.... you're saying there are no electrons around the nucleus of an atom, and no free electrons in a conductor.... I understand it's an old theory and we can't really see them to tell if they are really what we think they are. But last I learned they were calling it an electron cloud, and we have been observing atomic properties for thousands of years. Sorry, but where did you learn this? I feel as if someone just told me the earth is flat, and I just can't get behind it.

@@charlesdickens6706 ok, I get it... I didn't realize he only powered it for a second.... Kinda like a stater, or distributor coil. it reminds me of a demonstration my small engines teacher showed the class. He ran a 12v car battery through a coil, on a metal table with a rod in it. Every one formed a chain, one person touches the rod, and the last person touches the table... even though its a large volt no one feels it till someone let's go.... of course as soon as I heard that I had to be the one to do it first.

nice idea ate - cheers

Thanks, you too!

@UC04cdP4OJPkCgWQQ3i7QG2g it was the good luck part that threw me off.... that would be like wishing Bruce Lee luck in a fight.....riiiigghhyyyT Love you buddy

@@MaintenanceMouse So let me understand now you still have problems with my viewing time and when I commented I now have problems with what I said. Stop, take care of it

@@Inventive101 he doesn't need luck.... But after seeing your channel, maybe you do?

I dunno

Actually, he only claimed to coin the term, which he did in an on-line 2002 "how-to", 3 years after Kaparnik's article that mates an LED to a self-oscillating voltage booster. Clive goes out of his way to credit people he gets ideas/info from, and definitely credited Kaparnik in that posting.

Another Idea; Earth power like a earth battery? To a joule thief to power all these solar led lights that won't charge in my garden, I've plenty low voltage wire to string em to

Tesla captret to a Super capacitors to a Crystal battery to a Joule thief to a Tuneable oscillator to a Electromagnet ( a coil ) to Replace the magnet in a hendershot generator So the bias can be set correct to eliminate fire hazard? That's Hadleys take on a New Improved Hendershot Generator.

There's no requirement for a solid core. Hackaday project 160271 shows a coil etched on a PCB.

Yes it works

cheers mate

You can get *all* of the energy out of a non-rechargeable cell that would otherwise get thrown away.

it basically boosts the voltage from an unusable to usable level - so allows scavenging from low voltage sources like partially discharged batteries and thermoelectric generators

@@ThinkingandTinkering ok i got it.

Robert ive been doing electronics for 45 years and still into it.

awesome lol

@@ThinkingandTinkering vacuum tube jule thief...LOL ok

I wonder what effect it would have bending it round?

@@sarahhoward9081 it will work. I got this circuit to work using an M6 nut but it won't be very efficient.

yeah for sure - it would be quite like a flyback transformer then as the 'toroid' would have a gap in it

@@ThinkingandTinkering unless you spot weld it...

Ich habe genau gezeigt.

well I have my opinion on I tm mate - but it's just that - my opinion - who knows if I am right or not - I don't cheers

for sure lol
