    high voltage photo flash capacitor charger

    :)its funny you should say that audio guru , the only transister in the high voltage photo flash capacitor charger is the irf 540 n channel mosfet and the only ic is the timer  and the rest are just resisters and caps

    Ignition coil driver circuits and experiments

    :)thankyou for the humour audio guru , i decided to measure the outputs of all the high voltage units that are all turned off and with just the ignition coil driver with coil on, and starting at the bottom one i got a small voltage reading from the induction  and as i measured the others and as...

    Ignition coil driver circuits and experiments

    :)ive made an error here im not getting 1.45 volts im getting 6.99 volts output from my switched of high voltage photo flash cap charger via the induction from the ignition coil driver when i switch that on , even though the neon dose have a voltage rateing of ,well in this case its  pritty high...

    high voltage photo flash capacitor charger

    :)after ive discharged the charged up non photo flash capacitor into my first coil gun ive noticed that the capacitor still seems to hold a small charge even when its suposed to be discharged , a serch on the net for anserws , and ive come up with some mention about useing a led and resister to...

    Ignition coil driver circuits and experiments

    :)ive may of allready mentioned this but when i switch on one of my portable ignition coil drivers with single ignition coil in it and allso 12 volts lead acid cell rechargeble battery  , the neon light on the high voltage photo flash capacitor charger allso comes on and that unit sits on top of...

    Homemade capacitor holders

    :)here is the latest capacitor holder for my large 4700uf 250vdc cap i cut a section out so you can see its details          well i need to fix up a part that sticks out a bit so re heat it to soften it and its done

    high voltage photo flash capacitor charger

    :)the latest exsperiment im working on is a simple ring launcher exsperiment so as soon as ive got it all together and if it even flys a few inchers its good enougth to post it then , and powerd from the high voltage photo flash capacitor charger allso electro charger to seem that it can charge...

    high voltage photo flash capacitor charger

    audio guru i did use current limiting resister but at more than what the led with biult in current limiting resister can tollerate as like in the one transister version capacitor charge indicater the 1/4 watt just burns out so i use 1k at 1/2 watt

    high voltage photo flash capacitor charger

    hello audio guru there wasent any arcing at all  i had no problems with the 1 transister version capacitor charge indicater and its current limitimg 1/2 watt resister is between the led and top pos rail  so ill make a few changes to the circuit you posted when i stock up on moe trannies and use...

    high voltage photo flash capacitor charger

    :)audio guru that 350 volts capacitor charge indicater circuit you posted dident work it just blew the transisters  after the led blinked on bvriefly for a short time now the flasher led has a biult in resister so without one, i used a resister and led separate which should still work like the...

    Coil gun charger circuit

    :)audio guru there we are 3.0 amps forward current  ha ha ha ha  as said and the wire size  of the diode well my  10 watt resister has bigger legs than that.  oh thats a good idea that used car parts hey well im looking for a v8 engine to put in me coilgun to drive it to the test zone lol ha ha...

    Coil gun charger circuit

    :)audio guru those 1n5408 diodes in my dicksmiths catalouge says they are rated at 3 amps so i dont know where ya got the amps details on them from, as for the diodes well i got the idea of useing three of them from the circuit schematics for the high velocity electromagnetic launcher or ring...

    Coil gun charger circuit

    :)heres the latest picture, this time ive solderd the protection diodes in place and ran the input wires to the coil , i used 3x 1n5408 diodes and when i charged up the 200 volts 1200uf electro and dumped the charge into the coilgun it went faster, maybe the settings on the high voltage photo...

    Coil gun charger circuit

    :)hello mr heckles ive just biult my first coilgun  really simple to and ive been testing it  and i used the high voltage photo flash capacitor charger, which allso charges non photo flash capacitors and i get great results to ,

    high voltage photo flash capacitor charger

    :)the high voltage photo flash capacitors dont take to long to charge up, but there values aint so high so at 330 volts they charge qiuckly. but when i use an electro like 1200uf at 200 volts they take longer to charge as it seems but the charger neon dosent come on then, so the capacitor charge...
