    12 volts led power input indicator circuit

    This simple circiut setup, is what i use to indicate 12 volts dc into all my circiuts, even the high voltage circiuts. and for 24 volts input change the resistor to 1.2k . faceing the rear of the togle switch the togle at the front is switched upwards, when wireing up this ,to indicate 12 volts...

    What is the impulse response?

    That means that step input is : | 1 , t>0 u(t)= | | 0 , t<0 u(t) | 1 |-------------------------- |___________________ t 0 Right? Your system is this: INPUT : x(t)= u(t) OUTPUT : y(t)= impule response (unkown?) The relation between them is...

    Reverse polarity protection circuit

    This reverse polarity protection circiut idea was inspired to me by hotwaterwizard. my idea here was to use mainly microwave oven parts, starting with the microwave oven filter circiut, and relays, and i threw in a few diodes and a 1uf 350 volts electro, and a fuse holding circiut board that...

    High voltage pollarity indicator circuit/hv optimizer

    This simple looking circiut i modified to run off the high voltage output of one out of 2 high voltage output flyback transformers in a multiflyback driver circiut i biult, the leds work perfect no burnouts and by adjusting the driver circiut i get one led come on telling me its high voltage dc...
