    geophone kit circuit reqest

    thankyou audio guru the electro in the 741 circuit i remved before with your recamendations and the 1k to  so ill try the latest .by leaveing out the 104 monoblock

    geophone kit circuit reqest

    :)oh i forgot to mention, the 741 inverter circuit in this allso woeks without a battery  due to the induction of voltage into the coil from the slight movement of the magnet , the audio section has a battery to give audio reaction, i can see some good aplications here

    geophone kit circuit reqest

    :)still conducting tests of this circuit, but i decided to intergrate the audio amp to it  again and try something else and got a more sensitive  response of the circuit with the few powerfull rare earth magnets from further away from the coil  but even though the wieght of all the rare earth...

    Ignition coil driver circuits and experiments

    ive never seen a motor bike ignition coil before , but it dose make sense as even my car has 2 for the electronic ignition, and the coil posted has all the right stuff for a 2 cylender ignition coil on a moter bike i geuss

    Ignition coil driver circuits and experiments

    strange but looks like it has 2 sets of inputs and 2 hv outputs so you can make to high voltage cap chargers in one with that

    Close range RF Locator

    :)rf bug sniffer or the car tracker or beeper bug may be what  may intrest you, go to the talking electronics site on the net ,

    Bug detector

    :)youll find the rf bug sniffer circuit in the talking electronics site , may give you some ideas

    rf power amp

    :)sounds like you need a linear amplifier

    Phototransistor circuit

    :)look in the forums somewhere fairchild photo transistor data, it inclkudes 2 circuits that sense light, i used

    Car touch sensor!

    :)theres a circuit in electronics lab somewhere called an everything that moves alarm. and it has a metal sensor plate , can you use a whole car as the sensor plate , so it goes off when you get near it

    driver circuit for a n-channel MOSFET

    :)driver circuit for an n channel mosfet, well look at the high voltage flyback transformer driver circuits in the high voltage stuff section in electronics lab here they are n channel mosfet drivers, even for the high voltage p[hoto flash capacitor chargers one uses the n channel mosfet driver to

    want shocking circuit here!!!!!!!!

    :)go to the high voltage stuff section here in electronics lab  plenty good ideas there, you may find some great ideas in the topic generators, youll like the high voltage output hand powerd generator its simple to make to

    High Voltage Cap charger

    :)just grab any car ignition coil and use, it and even flyback transformers without the biult in high voltage trippler , will do  as for inductors which type are you refering to , i made a circuit i found on net, it uses inducter and it was suposed to make high voltage but it dident work ,  and...

    amplifiers used in Radar Immunization ??

    like a herf gun dose, high energy radio frasnquency transmission , it effects electronics , the herf gun well it uses a microwave oven magnetron  and this rf energy even effects transisiters to  etc etc

    Ignition coil driver circuits and experiments

    :)oh it would of been nice to see a close up of it , they have some strange ignition coils out , ive seen one with more than one hv output and it was rectangle shaped, and the one i used in one of my high voltage photo flash cap chargers as posted in the topic in the high voltage stuff section ...

    High Voltage Cap charger

    ;)use the transformer in reverse if useing the timer circuit for higher ac voltage output , if useing a voltage multiplier for high output dc dont ever use the 10uf electros with the 1n4148 diodes for it , you can use the 1n4007 types and bigger value  electros  just follow my high voltage photo...

    TV Disrupters and Cellphone jammers

    :)radio interfearence well it can be cuased my many things like a niosey electric moter  and lightening bolts to , even that cant be policed if illeagle  so what could they do well maybe man made interfearence, but then if that was the case theyed have to shut down any niosey factories with...
