flyback study with kacher 2.wmv
Hi all Experimenting with the stuff of my first experiment on this subject , i decided to test the exiting coil of the Kacher and replaced the pancake heavy copper 4 turns original with a 10 turns standard 1 mm copper exiting coil. I did not change the electronic circuit, so always the MJE13009 transistor with a 4.7 k resistor. Than after having testing all config ” thank’s Wattsup for proposals” i tried to go at the utmost simplicity. that is only one exiting coil and one main coil . And test what i could get from this arrangement. So here the result with 2 time a 3 watt LED 220 volts lamp with my special arrangement. I can get really good lighting with very few input power. But my special point here, is that as you can see …… all the circuitery is open i mean that the kacher end coil goes to only 1 lead of the lamp (the other is free ) than the wraping arround the lamp is from one part free and for the other connected to ground or thin air or negative of the battery. So we are here in pure exiting (i mean elctricaly thinking) world Can we do better ? yes i am sure so let’s go and good luck at all Laurent
