Joule Thief

[innovation_station]

just thought i would add this ... bout the magic maker ...

im doing slef run mode ... 

i have a problem with MY DRIVEING BATTERY CHARGEING FAR TOOOOOOO FAST ....

I STARTED LOW LIKE 1.255 RUNNING AND NOw IM 1.265   3 MIN OF PLAY ....


yikes ...

thought i would share ..

I CAN PROVE THIS  AND IT IS DUPLICATABLE EVERYTIME !

MY RESTING VOLTAGE OF MY DRIVEING BATTERY IS NOW 1.270

in 3 min ...

of course i can explaine!

just shareing!

now to switch my 3055 cost me nothing .......

and my supply recharges far too fast ...

this is no ghost charge or bag of TRICKS ...  lol   it is not only holding when i turn off my unit but RECHARGEING WHEN IT IS TURN OFF BY DESIGN!  IMAGINE... 

and when it is running .. i drop .005 volts UNDER LOAD! and it CLIMBES AS WELL !

what more can i say

THANK YOU !

Thanks for pic of conical, Is it a single wire coil running from bottom to top ?

jeanna
very interesting design there... ( TOWER of POWER )

ist
well done bro
is the feed back just a diode or is it filtered back with a cap
i had a circuit almost self run once 25-30 seconds .. got me excited and it died
i was using a inductor and diode back to a run cap on input

@All,
I have been having huge probs with my satellite broadband connection, turns out my Ethernet was the prob, now its working OK, but in 12 hours I blew all my hi speed download allowance for the entire month,(thanks to MS updates before I realised it) its knobbled back to 7k per second, (same as dialup grrrr) until its bed-i-byes time, but I ant staying up to all hours in the night for higher speeds.
Also I have to alter my email address.

Back on P758, I see a cry for help, how to connect a AMP meter to a circuit to measure Amps.
I dont know if anyone replied as I havent got that far ahead, just in case here is the answer.
And before anyone asks, yes I do know of 2 people on this forum who don't know how to do this, and there might be more.

The DMM will usually have several connection jacks for measuring Volts, Ohms, U-Ma (micro to milli amps) and Amps (10 amp limit)

Leave the Black lead in the (C) or Common Jack
Remove the Red lead and put it in the 10Amp Jack or the u or Ma Jack

Switch the DMM to the correct "RANGE" or place indicated on the meter, which can handle the "current" which you think will flow.
If in doubt, switch to the 10Amp position (range).


Connect the RED lead from the METER to power supply or battery.
Connect the Black lead from the METER (C) or Common Jack to the [LOAD]
(because you are measuring current, (+) POSitave will flow through the black lead now).

Connect the NEG wire from the power supply or Battery to the circuit.

See the jpg photos and circuit I made.
------------------------------------------

To measure total current flow by JT and Load.
Place the DMM leads between the 1.5v (+) Positave and the Joule Thief.

To measure the current drawn from a LED or Motor.
Place the DMM Leads between the JT (+) to the (LOAD)

PS its always best to have a dedicated meter setup to measure Amps or U-Ma amps, saves all the wire swapping or forgetting to set it back to volts and blowing the meter.

@ Jim, good to see you back here !  Hope things go OK for you soon !!!

What is the diff. between...(A) To measure total current flow by JT and Load.
                                          Place the DMM leads between the 1.5v (+) Positave and the Joule Thief.

And...                             (B) To measure the current drawn from a LED or Motor.
                                          Place the DMM Leads between the JT (+) to the (LOAD)

Is this right...  If you have a JT with LED, and you want to measure total current getting drawn from your
                    battery, you then place DMM(+) and (-)leads between the battery(+) and JT(+)
                    ... CORRECT ?

What then is the difference between (A) and (B)
what exactly do you connect DMM(+) lead to and DMM (-) lead to for (B)
Sorry for all the questions but I want to get it right.
