    simple ac dc field detector circuit

    :)heres the latest  pictures , one is the bread board design  for this and the final decal work  on the circuit box  which was an ac power transformer box of some kind, another test i allso done was to have it near the pc dureing its shutdown stage and the  leds respond by flashing and as the pc...

    simple ac dc field detector circuit

    :)when you switch this circuit on iether 1 of the 2 leds may come on, this is nothing to worry about as when you aproach the feild they then start to react to that feild

    simple ac dc field detector circuit

    :) in the circuit diagram , the letter l means link, thats tinned coper wire i used and the capacitor on the left is a tantalum

    simple ac dc field detector circuit

    :) well here it is , i spent time every  day working on this  and it works great, now, all i have to do is switch it on and  piont the ereal towards any ac or even dc voltage source, even high voltage ,  and the leds will respond. first of all if i aproach the wall switch the red and green leds...

    printed circuit boards for inetergrated circuits

    :)the holes may look slightly crooked but when you get it right you cant go wrong, that demo printed circuit board for a timer, the timer fits perfectly through those donut holes

    printed circuit boards for inetergrated circuits

    :)on the right hand side of the first picture you can see the demo version for a timer that i made useing this idea and i havent cleaned the  green off it yet . once youve cut and predrilled the alliuminium turn it over and snad the rough pin hole edges , smooth

    printed circuit boards for inetergrated circuits

    :)here is my simple idea which i have been testing for printed circuit board, designing , by the use of a home made alliuminium component leg, and ic pinout position stencil, first you need an alliuminium drink can , cut the top off with a pair of sizzers, then cut down one side, then cut the...

    flyback transformer driver

    i dont really know the technicle side of the flyback drivers, i just biuld them from  circuits ive collected  and they work great but if you power one driver from a 12 volts lead acid cell  with a current of even 2 amps or around that or maybe over or under it works even better  but at 12 volts ...

    Swinging arm assembly type ufo detector

    :) this only has a few parts  like c106d scr and led and 2x 1k resisters and a buzzer and a small easy to use sliding on and off switch, but like i mentioned i put a push off buton to open  the circuit

    Swinging arm assembly type ufo detector

    here is what the electronics section of this simple swinging arm type ufo detector looks like , now the 2 wires sticking out the bottom go to the contact section , one goes to the pivot stand where the swinging arm sits, on top of the pivot needle, and the other wire goes to the contact coil...

    High Voltage Stun Gun !

    ;)thankyou mp im flatterd, even though i collect circuits for a hobby and biuld high voltage stuff , im not  much for technicle exsplanation,s  but  it aint to hard to use a high voltage produceing circuit for things like a stun gun , audio  guru is good at the technicle side of circuits , i...

    high voltage photo flash capacitor charger

    :)in case you dident notice the 100 ohms resister is under the board, to see the picture ,instead of downloading it to see it just right click on the black square with the red cross in it, in the top left corner then  left click on show picture,

    high voltage photo flash capacitor charger

    the circuit thats near that funny high energy electronic ignition coil, its 100 ohms resister is under the brad as the only one i had left, its legs was to short to put on the top of the board so i solderd it under it

    high voltage photo flash capacitor charger

    unfortunately there wasent enougth room in the latest ignition coil version ,high voltage capacitor charger, pvc made circuit box to get the relay timer circuit in  . so i had to make a few modifications , and leave out the relay timer circuit, that shuts off the chargeing process after the cap...

    high voltage photo flash capacitor charger

    thankyou for the reply audio guru  ive put a diode across the relay inputs for protection before , anyhow as i upgrade the circuit ill add any new ideas you may forward  to the topic

    high voltage photo flash capacitor charger

    :)the capacitor from pin 5 on the ic is a 0.01uf ceramic or 104 mono block and the electro the the left is 10uf
