    hv polarity indicator/ voltage optimizer

    In these 2 pictures retesting this simple modified circuit, to give led indication of hv arc flow from one wire to the other , was delayed by the 12 volts battery powering the flyback driver circuit,runing low on voltage. the arcs were so thin you wont see them let alone the red led lighting up...

    Night rider scanner

    This redrawn simplfied circiut from my collection was drawn ina special way by circiut maker and retraced in black to highlight it enougth to come out when photographed, for posting, ill post another similiar one soon and because it uses more of the 4017 decade counter pins, it allso makes a...

    10 Led chasser

    This light chasser , i used to power 96 leds and used it as a lotto number picker , by tapping to each side of the electro. and runing the wires to a push button switch ,enabled me to create a short when the button is pushed, this stops the leds in there tracks . where the numbers for the lotto...

    1458 IC tester

    In these 2 circiuts the components are the same as that of the 741 ic testor except that they test each 741 ic out of 2 , in the 1458 ic chip , the wireing to each ic socket where the 1458 ic plugs into is the only different thing, youll notice , apart from the location of one push button and...
