    Coil gun charger circuit

    the inputs to the simple coilgun capacitor charge indicater i derived from the coil gun circuit i conect to the high voltage photoflash capacitor charger outputs that go to the capacitor being charged works well here ill post the pics of the latest high voltage photoflash capacitor charger as...

    Coil gun charger circuit

    the link to that other coil gun site now i checked it out and the 2n3094 transistor and led and 1k resister  in the circuit there used to indicate the capacitor charge ,i used those  3 componenets and intergrated them into the high voltage photo flash capacitor charger and the 1k resister kept...

    Assisting the troops question

    :)the magnetrons in microwave ovens are used to make the home made high energy radio frenquency guns , these were said to be able to set off land mines at a distance ,  but if you have the powerfull version i think useing the millitary magnetrons  you may get lucker then

    Assisting the troops question

    the best ways are herf guns ,thats high energy radio frenquency guns and scalar waves, herf gun circuits are in the forums somewhere ,  you may like to look at the min emp boc circuits to

    high voltage photo flash capacitor charger

    thankyou for the input, greatly apreciated , with the high voltage and current in the 350 volts photo flash capacitors i reckon i may be able to channel that voltage through the 35000 volts bridge rectifier i made of microwave oven diodes  at least it may give great reverse voltage protection ...

    high voltage photo flash capacitor charger

    thankyou audio guru  at least someone apreciates me autopsy on dead high voltage photoflash capacitor  its strange how the foil is grey and brittle and breaks so easily and with no holes in it or visible damage  i once pulled a microwave cap apart and its foil was still like foil and not grey...

    high voltage photo flash capacitor charger

    :)ive did some more exsperiments and testing of the high voltage photo flash capacitor charger and by the fels of the charge on the capacitor it must be over chargeing so it appears to be ok but you can use a current limiting resister to help preserve the life of the capacitor , i  charged up a...

    key chain laser power supply

    i used a fairchild photo transister if you look in the forums in the parts data sheets etc it should be in there as i posted the data sheet for it there

    high voltage photo flash capacitor charger

    thankyou audio guru, my first high voltage photo flash capacitor  charger, charges up really fast as the flyback is similar to the one i used in this second high voltage photo flash capacitor charger , i dont now why the led blinks on and off as its chargeing  maybe , something there to look into

    high voltage photo flash capacitor charger

    audio guru the circuit is the same as the 350volt circuit attachment you posted here  im not useing a blinking led and the wires from the capcitor charger run to this circuit and from there to the photoflash capacitor under charge,  i havent measured the volts in the capacitor under charge yet...

    high voltage photo flash capacitor charger

    now to look into methods of indicating  when the high voltage photoflash capacitor is charged up, and from  a topic in the high voltage stuff section here i went to a site  of coil guns  or something and found a coil gun circuir that has a capacitor charge indicator circuit in it so i derived...

    key chain laser power supply

    ive never had it runing for a long time to be able to tell you hoe dureble it is and unlles i get it all boxed up and tested fully i dont know howlong the power will last but im confident it may last for days

    high voltage photo flash capacitor charger

    heres a close up of the board, note the 555 timer is isolated from the board and the pin positons on the board where the timer would of been has wires from them to the timer pluged into the ic socket which is mounted on an ic mounting board and the timer protrudes out the fron pannel so...

    high voltage photo flash capacitor charger

    :)heres the lastest pictures taken before i put the laste terminal post in and the wireings all done and the pannel work except the lid  and i tested it and it charged up the high voltage photoflash cap so good you can feel the charge in it with your fingers and it sure goes bang when you short...

    Potentiometers with center detent?

    sounds like those potentiometers  used in the balance  controls of stereo systems and radios  as when you rotate it to the midle it clicks like it has rachets in it  and you get ven sound on both speakers  in your stereo so if you need some pull them from old discarded junk  as i have to and...

    Coil gun charger circuit

    thankyou have you biult this yet and tested it  chargeing capacitors up may be very usefull , have you tried biulding the high voltage photoflash capacitor charger that ive posted you see this is unlike the typical photoflash capcitor charger circuit of any pocket camera as when you put your...

    Coil gun charger circuit

    can you do a more clearer circuit as bits seem to be hard to see and i cant make out ic2 and  and one of the tracks is missing at the top
