Don Smith Device Project Part 20a: Bell-shaped Wave-Form and Output Testing
Very pleased with the results from this new setup -Variable Freq and Pulse Width adjustable with 2 dials from 20khz to 300khz + with various cap combinations and 0-100% duty cycle -anti-parallel double ignition coil driver (seems to give double the freq than single) so when one is pos, the other is neg -snubber between ignition coil primary is a 1kv .1uf parallel with a neon and those are series with a 10kohm resistor, havent blown any chips since and the neon lites when duty cycle is to high -small 5 amp analog meter to view input from 12 v battery -L1 is 4 ft of 3mm insulated cable (too thick is not good) with .005uf -L2 is 16 ft of B&W Airdux inductor half rewound to cw ccw (WHAT A BITCH THAT WAS) Dons popular double helices board is strangely wound all one direction 🙂 with 1.54nf between center tap and output end of L2 -adding more or less capacitance on L1 or L2 took away from output -Seemingly increased spark on output with more firey and violet apearance than the blue-white input spark -output bulbs are the same 12vdc 30 amp automotive bulbs -very strong output over the 92 ohm load 5 bulbs with more to offer 🙂 MEMORY CARD GOT FULL AGAIN, or i wouldve shown what a core does… -No change in wave form or current draw when output is short-circuited -Seemingly no drop in input battery while drawing 1 amp continuously after 2 weeks -Shocks recieved right off both battery terminals during operation -Rising exponential looking increase seen in the wave-form was achieved …
