Joule Thief

they make even better cold fusion as i think it is called


but this gets dangrous ...  i have exploded a poor designed hho cell in the past ...  it was a weeeeee bit scary .... 



i think if you did this under water you will run the risk of burning the hho under water ...  as your makeing hho and oxy  i bet it boils water fast and cheeply .... 

some one need a water heater ??

what tepm does it take to melt carbon rods?

ist!

sheesh now you have my cold fusion cell driveing my turbine on steam pressire and turning huge hpg's at a damm high speed ... from a jt next ...  yikes ... 

now what ?   ever gonna throw a dollar in the street for the child on the street ?

w

here ya go ...   IH  you rock bro!

@ Yucca

Thanks for the report. I would think you must have had to changed your 100 ohm resistor to a 10 ohm resistor in order to get the transistor to turn on with 1.5 volts. In fact, I would suspect that it would work with only the 1000 ohm resistor when using 1.5 volts.

EDIT: I see you were posting the same idea while I was posting this.

EDIT 2: I think I was wrong about the 10 ohm resistor. You would need a larger value, not a smaller value to replace the 100 ohm resistor.

I was amazed myself but I was running at 1mA 1.5V using 100 Ohm and 1k Ohm divider network. This transistor needs only a miniscule base current.

But yes, for best low V operation the divider needs taking out, the base needs tying high with a resistor (value found thu experiment) then the trigger coil tied to base via another resistor (value thru experiment). This eliminates the constanlt load accross the rails present with the current design. Of course it would only be tuned to a narrow input voltage range, but it would be hella efficient! Maybe OU?

@ Yucca

Here is your circuit drawn as typical Joule thief but with your resistor biasing. I think this is correct.

Hi xee2,

yes pretty much spot on, here's the circuit:

Folks:

just a cautionary note, if you do run up one of these devices, keep any solid state measuring equipment well away from the HV output, it'll get zapped lickety split!

Yes.  The Cockroft-Walton generator in resonance should give you up to, say, ~250,000 VDC
Use HV caps with as large a value as you can afford.
(I got that info from an old reference on building Cockroft-Walton's.)
You might need to wire them in series/parallel to get more voltage and amperage?  Depends on what's available where you are.

HELLO LEE

this is the diode i have about 1000 or more of them i looked up the specks ... 50 - 1000v fr 305 -306 i have used both

FR = FAST RECOVERY ...  RECTIFIER DIODE ..  UP TO 1000V 3 AMP   I COULD COOK AN EGG ON IT
