Joule Thief

[gadgetmall]

@all
What i am about to show you is a Closed loop  JT circuit on my proto board . I have secured a neo Patent so i claim all rights to this circuit and the concept  .It lights and keeps it's own battery charged I Its been running for a week now with  an alkaline battery gaining In Voltage very rapidly. I   call this the Rainbow effect .I still have to Load it down a bit as the volts is way over the normal AA voltage . Don't be fooled By the Medusa Toroid Coil(Another Coined Phrase) , It works good !Schematic of this unit will be it in Kit .and  i will offer a schemitic for everyone to play with  here .  .

well i guess i have a few hall sencers ....  round 


last night i found a aa to cell fone charger at ramma for 2 bucks 

puts 4.5 v dc ...   works good for a supply ... 

congrats jesus ... 

getting intresting now

red leds and schottky diodes work well in crystal radios in place of the germanium.

Really?
I thought the entire idea of the crystal radio was to use a very sensitive germanium diode
in order to utilise the extremely weak signals... And since red LEDs and schottkys tend
to need much higher voltages to work, I would expect a crystal set with them instead
of the Ge diode to be a lot less effective with weak input signals...
... but I suppose they can work if the coils transform the weak input to a higher
voltage pulse in a JT variation that merely uses the crystal set to get input.
It's a good idea to try anyway.

Still, I wonder which producs more, a fullblown crystal set circuit, or the
relatively simple "Tate Ambient Power Module" (which is in fact a simple
rectifyier using sensitive Ge diodes to catch even the smallest fluctuations).
I wonder since a crystal set is basically a Tate module with a tuned/tubeable
LC circuit attached...

Anyone?

@Al/Fusionchip/Gadgetmall:
Nice pics there!
Did you post a schematic of this circuit earlier? If so, I must dig around
in the thread to find it. If not, are you going to?
Definately something to try and replicate, that circuit of yours!
lol "Medusa coil"... I suppose that refers to the coil shag and not
to how vicious it bites?

really. you are correct in that germanium diodes are hard to beat for most low frequency crystal radio designs if no bias is desired, but schottky diodes will work better without bias if higher source and load impedances are achieved.
all that aside, put 10uA bias (easy to get, be clever) on a schottky and it's the clear winner by a long shot. red leds need bias and are really only ok for low freq. but hey, don't take my word for it, build one and try different diodes. expectations can easily be confirmed or dismissed this way.

build them both, try different diodes, gives more definitive results than wondering

i just wound a new mk2 on a black toroide .. i know it is ok for this as it was previsly wound similar....

but i used bell fone wire ..and i made  them the exact same lengt jt coils and then i x it by 3 and made the mk2 winding

it is coloured coated wire so i can correct my winding if it is wrong ... 

now last night i bought a nova shake it flashlight  i removed what i thought at first glance a super cap but indeed it is a small rechargeable nicad .... 

it is all ready to go lol so i will use it   

i also bought a few crank it flash lights same deal ...  wich is ok



so im throwing togather another small unit ... that can and will self run with output 

i will get 1 more nova shake it light ...  they both will be hooked up on the secondaries.... for out put ...  i have the curcuit from a crank jobbie ..  flash light i will put on the jt fly back ...  to self power ...   we will use a small cell fone charger to power the ring ... from a aa battery only for a few min     to fill the nicads....

and if i go further on this   i can use the cell charger only to fill the jt fly back nicad ...  THE FIRST TIME ... 

LETS CALL IT A KICK START   LOL    so whan i compleat this it should be offered as a closed loop kit with a kick starter ... 

and cheep ...


ist!


i need guys that could place togather kit instructions ... assembly    the whole deal   ...  and  im sure we will work out some thing ...

anyone intrested in this job   PM  me

here is a pic of this unit in the works
