Joule Thief

[gadgetmall]

Hello everyone . I would recommend what mark said and concentrate on Lightsabers joule ringer . I have replicated it and have not got it to ring for very long on caps but on a battery i ran cfl and led for 16 hours with a GAIN in the battery . this is called reguaging . So the total draw on this circuit was so tiny my meter cannot register it . it was well below 1/2 microamp and the voltage was going up instead of down . the result was i started with a 1.245 volt battery and at the end of 16 hours standing volts was still 1.245 . Very interesting stuff . uses two components and with a few different  mods i did a few more replications and it keeps getting better ! .first pic is my second rep of lightsaber joule ringer and second is lamp brightness next is my mod to lightsabers joule ringer into a battery regauager and last is a mod i did this morning using a coil i wound by HAZENS way . the battery remains the same all day long and is still running in the corner and volts are 1.235 now but the start volts on that aa battery was 1.225 before it ran all day . first pic using AAA fuji transformer and transistor and lightsaber coil with 4 germanium diodes on it . other component is 2 2200uf 25v electrolitic caps parallel to the battery and thats it. . 1 volt very bright .also it will not run  or reguage on a super cap or an ultra cap. it drains it within 30 minuits . weird .

9 hours later ....with the hazens coil replacing lightsabers bifialar .plus some mods i did and sometime around noon i added a 68pf across my little pot but i didnt disconnect the circuit . it made it work a bit better i think .well worth the time spent on this ..the photos are about 3 hours apart and its not a meter fluke . I shut the system down to check the standing volts and for sure it is always above or at the beginning standing volts . Nice . I am not saying its ou its prolonging the battery by reguaging it . Time will tell . STill this is better results that my fugi mods i did a year or so ago with run time 24 hours on an aa battery . this will beat that by far . thanks lasersaber!

turn it up a bit make it more impressive

Well its not that bright Bolt   and the other pics i took were in the dark no flash but it will light a room up and you can read by them . Those little Cfls do put out some good light .Plus i have this one turned down . i can turn that pot and get some serious light but it wont reguage as well . that will be a test for later .This is a bit brighter than my 26 watt CFL lamp fixture that runs for about 24 hours on an aa. I broke my record on running a cfl with this lightsaber circuit using a battery and a jule thief coil instead of a stubblefield coil . 27 hours so far and plenty of juice still in the battery and Cfl lit the same along with an led running off the torroid secondary 1.229-1.230 after 27 hours . not bad i must say . this will probably run for another 2 or 3 days i suspect . I have not been on in a long time like a year or so so that record is probably old anyways .
@all Great job on your Jt's and recording the numbers . Let's keep this thread alive and please do continue on with all projects .

could some one pls answer my question from befor?
it was about having a battery and resistor is series
and masureing the ampage
is it 16ma allowed max or is it the usage of the resistor?
