    Ignition coil driver circuits and experiments

    :)with the parralell coils i have 2 or 3 arcs but the first hv out on the first coil to the second hv out are the bigest arcs if you space the first hv out electrode far enougth apart  now i dont know if its nessisary but here is a mini spark gap just in case,

    Ignition coil driver circuits and experiments

    :)the ignition coil driver dose have some good uses in exsperimenting with arcs and since ive come up with the simple capacitor charger in the other topic for chargeing capacitors up with by the use of the ignition coil with its ignition coil driver circuit  , here is a recreation of one of my...

    Best circuit drawing software out there?

    :)i use that circuit maker to, the free student version down load one and there are features you can use in it that  that it dosent seem to really admit  it and when i emailed myself a copy the email came back ok but the extra features  dident come in with my email so they are lost so just...

    Need help deciding on a multimeter

    :)at times like that it would pay to save your dollers and get a multimeter that will be ok like digital multimeter and if it has continiuity checker and transister tester to or even a thermal probe and high impeadence would be my choice

    How can I discharge a capacitor...

    :)in that case just short it out with some heavey wire

    Cleaning potentiometers

    i mean potentiometers just spray some in the little opening and rotate the pots so that all that dirt and stuff is cleaned out  and the pots, if they are a bit stiff should be easyer to rotate then, you can use crc to

    high voltage photo flash capacitor charger

    :)anyone planing on biulding this ignition coil version cap charger i just found out it , that the positive output  puts out arcs to ya finger to but somehow when i hook up a capacitor to it it charges up great with no damage  yet as if the cap has an internal resistance  of its own

    Wind power generator project

    ;)intersting saw a great wind power generater on the new sieries called beyound tommorow and the thing is wierd instead of blades like a windmill it has a big loop of metal and its twisted on each side to form a blade ,  if ya gona biuld a wind power generater ya would need it to spin a genrater...

    high voltage photo flash capacitor charger

    :)here are some of the test results;  photo flash caps with there lower uf values seem to take  less time to charge up and the higher the value the longer it takes but the results are rewarding when you short them out and get the big bang , the neon charge indicater gets reallybright when the...

    high voltage photo flash capacitor charger

    :)if you zoom in on the positive output terminal inside the box you may see the 330k 1/4 watt resister. here is the front of the cap charger and the neon is protrudeing out the white pvc pannel peace so ill be modifying that next time so it will be a green charge indicater light , by modifying a...

    high voltage photo flash capacitor charger

    :)here is what it looks like now  . the 330k reister you cant see as the leads are in the way  this unit used to have  a modified high voltage polarity indicater in it , useing diodes rated at 15kv each from microwave ovens , but i took it out to do the leatest modifications,

    Coil gun charger circuit

    :)the 555 timer and irf540 or 640 or 740 n channel ,mosfet and potentiometers are separate and not on the board so the pins you see are where the wires from the timer and mosfet and potentiometers run to . here is another flyback ill be useing in this latest cap charger for the coilgun  now ive...
