Making a Joule Thief Circuit with Steven Chiverton - Part 1

Here are some recent updates sent to me by my friend Steven Chiverton. It's about the very popular joule thief circuit improvised by Steven in his own way. Let's get to the core of the developments with the following article:


POINTS COVERED:


  • STEVENS RADIANT JOULE THIEF BATTERY CHARGER CIRCUIT TESTS AND RESULTS SUNDAY MAY 9TH 2010.

  • THE RADIANT JOULE THIEF CIRCUIT I BUILT FROM A CIRCUIT SCHEMATIC FEATURED ON A YOUTUBE VIDEO AND HERE ARE THE RESULTS SO FAR

  • WITH A AA SIZE ENERGIZER BATTERY, WITH A MEASURE VOLTAGE OF ONLY 1.029 VOLTS LEFT IN IT I GOT AN OUTPUT FROM THE RADIANT JOULE THIEF BATTERY CHARGER OF 12.16 VOLTS @14.7 MILLI AMPS.

  • TEST 2 USING A SMALL A23 ENERGIZER BATTERY WITH A MEASURED VOLTAGE OF 9.72 VOLTS IN IT I GOT 10.96 VOLTS OUT FROM THE CIRCUIT @0.325 MILLI AMPS.

  • TEST 3 I USED A FULLY CHARGED NIMH RECHARGEABLE 9 VOLTS BATTERY WITH A MEASURED CHARGE OF 9.19 VOLTS DC IN IT AND I GOT 51.4 VOLTS @137.3 MILLI AMPS OUTPUT FROM THE RADIANT JOULE THIEF BATTERY CHARGER CIRCUIT.

  • TEST 4 I USED A 3575A BUTTON CELL BATTERY WITH A MEASURED CHARGE OF 1.36 VOLTS IN IT AND I GOT 12.59 VOLTS OUT @8.30 MILLI AMPS.

  • TEST 5 I USED AN L1154 BUTTON CELL BATTERY WITH 1.31 VOLTS MEASURED IN IT AND I GOT AN OUTPUT OF 12.90 VOLTS @7.50 MILLI AMPS.

  • WITH AN SLR BATTERY WITH A VOLTAGE OF 12 VOLTS LEFT IN IT  I GOT 54.9 VOLTS OUTPUT @0.15 AMPS.

HERE IS THE SIMPLIFIED DRAWING I BIULT THE RADIANT JOULE THIEF BATTERY CHARGER BY. THE INDUCTOR I WOUND SO MANY TURNS TILL IT WAS TO FULL TO WIND ANYMORE BUT I BROUGHT 2X 5 OR 6 METER LENGHTS OF STRANDED COPER WIRE UNKNOWN GAUGE FROM DICKSMITHS ELECTRONICS INSULATED WIRE AND I WOUND MOST OF IT ON EXCEPT I THINK A FEW FEET LEFT OVER.
THE LATEST TEST I USED MY PENCIL ENERGIZER BATTERY BUT I DIDENT REMEASURE THE VOLTS IN IT, I POWERD THE RADIANT ENERGY JOULE THIEF WITH IT AND AT THE OUTPUTS I PUT A 2200 UF ELECTROLYTIC CAPACITOR RATED AT 50 VOLTS AND I RAM MY MULTIMETER LEADS FROM IT AND GOT UP TO BEFORE I STOPPED 35.8 VOLTS , AND THAT’S THE CHARGE BEING FED INTO THE CAPACITOR TO  , BEFORE THAT I WAS GETTING 27.8 VOLTS BUT AS THE CAPACITOR WAS CHARGEING PAST THE HALF WAY MARK THE VOLTAGE CLIMB WAS SLOWING DOWN, MAYBE DUE TO THE VOLTAGE FROM THE BATTERY GETTING LOW. ILL HAVE TO REMEASURE IT AND DO THE TEST AGAIN IN MORE DETAIL.
SHORTING THE CAPACITOR GAVE A SNAP NOISE AND SPARKS.

I TRIED IT AGAIN CHARGING IT SO FAR BUT THIS TIME I DUMPED THE CAPACITOR CHARGE BACK INTO THE INPUT AND THIS ILLUMINATED THE NEON FOR A SECOND BEFORE THE CAP CHARGE WENT DOWN

NEXT EXPERIMENT WAS DIFFERENT I HAD THE OUTPUTS TO MY METER SET TO 200 MILLIVOLTS RANGE AND THE NEGATIVE INPUT I HAD MY A23 ENERGIZER NEGATIVE SITTING ON THE NEGATIVE INPUT AND THE TOP POSITIVE WELL MY FIN GER WAS ON IT ONLY AS FOR THE POSITIVE INPUT IT WAS RUN TO A RECTANGLE PEACE  OF CIRCUIT

BOARD ON THE END OF A WIRE HELD IN THE AIR BY AN ALIGATER CLIP WITH MY OTHER HAND AND THE READINGS WAS CLIMBING AT A FASTER RATE I GOT O 47.2 MILLIVOLTS BEFORE I STOPPED IT I WAS GETTING POWER AT A GOOD RATE FROM NO WHERE WITH AN OPEN CIRCIUT HERE BUT I WAS ALSO HOLDING THE BATTERY CASE TO WHILE DOING THE EXPERIMENT.

I JUST REPEATED THESE TESTS AND GOT A TOTALLY DIFFERENT RESULT NOW I WONDER IF SOMETHING ELSE CAME INTO PLAY OUT THERE THAT MAY EXPLAIN THE SUDDENT GOOD RESULTS I GOT BEFORE.

I TRIED THE RADIANT JOULE THIEF BATTERY CHARGER FREE ENERGY EXPERIMENT AGAIN BUT GOT JUST OVER 11 MILLIVOLTS SO I SO I PUT THE 2200UF ELECTROLYTIC CAPACITOR RATED AT 50 VOLTS ACROSS THE RADIANT JOULE THEIF BATTERY CHARGER OUTPUTS WHICH RAN TO MY MULTIMETER SET TO THE 200 MILLIVOLTS RANGE. AND THE READING WENT UP AND THIS TIME I SHORTED OUT THE ELCTRO AND WHILE FILMING IT IT WENT TO ZERO BUT ALSO I HAD THE A23 ENERGIZER SITTING NEGATIVE ON TOP OF THE POSITIVE INPUT OF THE JOULE THIEF CIRCUIT AND MY RIGHT HAND WAS HOLDING IT AND I PUT MY RIGHT HAND FINGER ON TOP OF IT AS TO USE MY BODY BUT IT STILL FORMS AN OPEN CIRCUIT AND THE VOLTAGE WENT UP PAST THE 50 MILLIVOLTS RANGE.

REVIEW I FILMED IT ON MY HANDY CAM THE RADIANT BATTERY CHARGER JOULE THIEF POSITIVE INPUT RUNS TO A COPER RECTANGLE CIRCIUTBOARD, SITTING ON MY DESK TO ACT AS A RADIANT ENERGY RECEAVER.
THE NEGATIVE INPUT HAS THE A23 ENERGIZER SITTING ON IT SO ITS NEGATIVE IS ON THE WIRE AND AS I HOLD MY RIGHT HAND FINGER ON TOP OF THE BATTERY THE OUTPUT WITH THE 2200UF ELECTROLYTIC 50 VOLTS CAPACITOR WHICH WAS SHORTED OUT TO ZERO CHARGES UP AND THE MULTIMETER SET TO 200 MILLIVOLTS RANGE READINGS CLIMB PAST THE 50 MILLIVOLTS RANGE.

MY NEXT PLANNED RADIANT JOULE THIEF BATTERY CHARGER WILL BE USED WITH IT TO TRY PUSH THE MILLIVOLTS PAST THE 1 VOLTS RANGE
USING BOTH RADIANT JOULE THIEF BATTERY CHARGERS AT THE SAME TIME, I VIRTUALLY HAVE 2 ANTENNAS THE COPPER BOARD AND MYSELF.

WITH MY RADIANT JOULE THIEF BATTERY CHARGER LEFT SITTING ON MY DESK OVER NIGHT WITH THE BATTERY NOT BEING USED, IT HAD GENERATED A TOTAL CHARGE OF 152.1 MILLIVOLTS ALL BY ITSELF

LAST NIGHT I NOTICED THE MILLI VOLTS WAS CLIMBING BY ITSELF SO I LEFT IT AND JUST FOUND OUT WHEN I TURNED THE MULTIMETER ON ITS CHARGE WAS THEN 152.1 MILLIVOLTS. ITS NOWHERE NEAR WHAT I WANT BUT ILL WORK ON IT ANYHOW.

I RE TESTED THE RADIANT JOULE THIEF BATTERY CHARGER I CHARGED UP MY 2200UF ELECTROLYTIC CAPACITOR TO PAST ITS VOLTAGE RATING OF 50 VOLTS BEFORE THE TRANSISTOR COOKED AND THE BATTERY POSITIVE GOT HOT. NOW WHEN I HAD IT HOOKED UP I HAD MY METER ONLY ON THE 20 VOLTS DC RANGE SO WHEN I SWITCHED IT TO 200 VOLTS RANGE I INSTANTLY GOT OVER 71 VOLTS READING ON A 50 VOLTS 2200 UF ELECTROLYTIC CAPACITOR THE CIRCUIT APPEARED TO SUCK THE 10. +? VOLTS LEFT IN THE 12 VOLTS 7.2 AMP HOUR 20 HOUR SLA BATTERY SO MUCH IT HEATED UP ITS POSITIVE TERMINAL AND COOKED THE TRANSISTOR, ALSO THE CAPACITOR CHARGE I CAN FEEL WITH MY FINGERS AS I WAS HOLDING A WIRE ON IT THAT HAD COME OFF AND MY FINGERS WAS TOUCHING THE OTHER CAPACITOR LEG TO. I THOUGHT I HAD MY CAMERA ON STILL BUT DIDENT AND I WAS NARRATING IT FOR NOTHING.

IT LOOKS LIKE FREE ENERGY FROM THE AIR JUST AINT ENOUGH TO POWER A JOULE THIEF EVEN LETTING IT GENERATE BY ITSELF JUST OVER 0.904 VOLTS AINT ENOUGH.

  1. The phenomena you witness is not free ambient energy! The joule thief simply allows you to extract the residual energy still in a dead battery.
