Joule Thief

[jadaro2600]

SO, it's been a while since I posted here, and about a thousand posts I don't feel like reading.

I noticed someone made a jule ringer - looking at the design, it seems to have nothing to do with a bell, but it's lighting a CFL with a capacitor.  Looks like designs are improving.

I've considered the following design ideas to be most pertinent:
:: use of a CCFL ( Cold Cathode Compact Florescent ) tube, either in twist form or in straight tube; these can be acquired from otherwise defunct scanners or the hardware store; NOTE, these types of CFL's bulbs are dimmable and can be used in three-way lights.
:: Lowest possible current consumption
:: The higher the frequency, the more agitation that will occur inside the tubes, the more light is produced with less current.
:: Source voltage is irrelevant considering the number voltage sources available, ...

With two D or C sized batteries, I estimate I could get an astonishing amount of light for a long period of time.

So, has anyone bothered to purchase on of the 1 watt giant LED's? ...  I have been seeing more of these available at walmart lately as dimmable CCFL's and screw in LED spot lights ...  i have one in my desk lamp now and it produces a very night tone of light without and unusual oscillations.

Hi everyone keep the faith , the world you think you know was a fraud , but the fun is over 800 will soon fail form all over the world they will be removed from power very soon ... including some worlds favorite slayer .

God i love this planet !

@ MK1, what do you mean ?

@ All, I have just put my Solar panel and frame up outside, running with a 14 meter (15Amp) cable.

However when connected to DMM or analogue meter, it reads about 5 Amps through the 14 meter cable,
but if I dont use the long 14 meter cable... I get  9-10 Amps, why am I loosing  4-5 Amps through the cable ??
Oh, the volts are at about 2.5-2.6 with short or long cable.

you loose amps because dc voltage dosent travel very far and the resistance of the cable
