    Experimental high voltage bridge rectifier

    re kevin weddle. kevin this was just an exsperiment with the similiar workings of a smaller bridge rectifier , feed ac into it and get paulsating dc out, as for the capacitors i need for it, i have a big box full but not what i may need. so untill i can get the right parts this exsperimental...

    hv polarity indicator/ voltage optimizer

    :D re kevin weddle. kevin thanks for arsking the only indication i have of high voltage flowing is the arcs i get and the 2 leds lit up via a 1m 1/2 watt resister, i dont have a voltage devider nor the room to biuld one on my crowded desk. all i have is a multimeter but even i aint gona risk...

    hv polarity indicator/ voltage optimizer

    :D weddle oh i forgot i did test the hv polarity indicator on another flyback transformer, with its hv out and return both at the top, this one i can adjust the driver circuit and one led will light up showing hv dc to be flowing but when i readjust the driver circuit more, the other led...

    hv polarity indicator/ voltage optimizer

    :D weddle the driver circuit used to power the high voltage tv flyback transformer is powerd from a 12 volts rechargeble lead acid cell battery, some high voltage flyback transformers normally have biult in high voltage tripplers , to put out tripple dose, im not far from completeing my 21st...

    produce electricity using quartz cristals...

    :)this is intresting , the generation of electrissity useing quartz crystals. well when the movement of the earths crust happens dureing an earth quake, the quartz in the ground is subjected to alot of stress this causes it to give off energy , now you can test this on a small scale, you will...

    LED Flasher (very Interesting.............)

    ;)as nice as it looks . the light chasser circiut has a good use. i biult a double one, that powerd .more than 90 leds but i used it as a lotto number picker, and by taping into the electro and by shorting it out via a push button switch i was able to stop the leds in there tracks ,thus...
