thought i would throw a pic of it up so people can see the possible useful tool for playing with gating

    * 10Hz to 10MHz repetition rate
    * Pulse delay of 40 ns to 10 ms
    * 0.5 to 10V output into 50-ohms
    * Rise Time: 5 ns

i completed my order of componets.. got a couple different optos, some scr's and the stuff to complete my variable source transformer conections such as a inline thermal 10 amp breaker, neon indicator light, a standard house socket for output

i plan to connect the pulse generator to a opto and have the opto drive the gate signal of the scr so i have the isolation betwween the hv and my pulse gen..

donald i love the videos.. in the second one have you noticed how the voltage is climbing in sync with the ringing on the video? also how once the voltage step up to around 12.3 volts productions kicks on as if you just turned on the switch..


check out whats going on in new mexico the 29th of next month..

the loudness increases as the amps increase because the coil is vibrating with a stronger force
i don't adjust the frequency until the end of the video

I have a question about the 8XA circuit. Ok all the IC's (555, 7490, 7404) use 5V, so what was the 12V from the power supply for??

According to the picture you drew, they use 12 volt and the 5 volt goes to the last chip?

yea when I drew that up, it was before I took any electronic classes. The 555 can handle the 12V but the 7404 and 7490's are 5V. I've hooked up 12V to my pulsing circuit before but the 7404 and  7490's got warm so I just went back to 5V.  If you the 12V were to run the IC's then what would the 5V before? Ya know what I mean? lol  I really think we are missing something here with this circuit.

its a mistake on the print i believe they make a 5 volt 555 timer called the tlc555 or somthing like that... you gotta get that one and the circuit is 5v..  there is also a revised version of the circuit that dydnodon posted when he was working with the guy selling the car..
