Nice work Thane!

Looking forward to some nice pictures of the setup.

The OU is starting to taste SWEET!

DEAR WATERHOUSE,

IS THAT HOUSE BOAT OR OUTDOOR WATER CLOSET?

ANYWAY I UPLOADED SOME PHOTOS FOR YOU HERE:

DEAR WATERHOUSE,

IS THAT HOUSE BOAT OR OUTDOOR WATER CLOSET?

nope just a house on water

BEST TRANSFORMER RESULTS YET!

DEAR ALL,

PLEASE FIND ENCLOSED WHAT I CONSIDER THE BEST PHOTO DATA YET!

INPUT VOLTAGE = 38.13 VOLTS
INPUT CURRENT = 0.02 AMPS
POWER FACTOR = 28.6 DEGREES OR 0.876

INPUT POWER = 0.668 WATTS

OUTPUT = 10.75 VOLTS OR 1.16 WATTS

EFFICIENCY = 174%

PLEASE NOTE THAT THIS IS NOT THE BEST "BRIDGE" BUT A MAKE SHIFT MASH-UP - HOWEVER THAT BEING SAID - EVEN IF THE POWER FACTOR WAS 1 (WHICH IT CLEARLY IS NOT) AND THE CURRENT WAS 0.03 A - IT WOULD STILL BE OVER UNITY.

THANKS JM!

NOW LET'S TAKE SOME LIBERTIES WITH THE ABOVE PHOTO DATA

1) ASSUME POWER FACTOR = 21.6 DEGREES OR 0.93

INPUT POWER = 0.71 WATTS
OUTPUT POWER = 10.75^2 / 100.5 = 1.15 WATTS
EFFICIENCY = 162 %

2) ASSUME INPUT CURRENT = 0.03 AMPS

INPUT POWER = 1.01 WATTS
OUTPUT POWER = 1.15 WATTS
EFFICIENCY = 114 %

3) ASSUME INPUT CURRENT = 0.03 AMPS & POWER FACTOR = 0.93

INPUT POWER = 1.06 WATTS
OUTPUT POWER = 1.15 WATTS
EFFICIENCY = 108 %

I AM IN THE PROCESS OF REWINDING THE TRANSFORMER WITH A LARGER HIGHER GAUGE WIRE AND SECONDARY CORE WHICH OUGHT TO DIVERT EVEN MORE BACK EMF INDUCED FLUX - THIS WILL HAVE A TWOFOLD EFFECT OF LOWERING THE POWER FACTOR AND LOWERING THE INPUT CURRENT.

@cranky,
Very impressiv - thats overuntiy!! Just to make sure nobody can dispute it how about using a more accurate meter to measre the inpout current? That clampmeter is only accurate to 3 digits so if its reading 0.02, then the real numebr could be as high as 0.05, which would then NOT be overuntiy. So getting the  proof needs a better meter - how about that grey bench meter in the earlier photos - it also measures pf directly. ITs headline news if you can get the proof measurements.
