Don Smith Device Project Part 19 B: New Driver testing
Part B …From the one Hv terminal i have the spark in SERIES with L1, then the air cap is parallel with the HV outputs. Freq in that vid is roughly 50khz…im guessing. waiting…

Don Smith Device Project Part 25 B: Single Turn Secondary Step Down :D
Hehe also tried a single turn primary here 😀 was… interesting 🙂 So im going to optimize the step down transformer, and possibly incorporate Thane Heins’s Bi-Toroid in the process. Although there is already…
Don Smith Device Project Part 25 A: L1 vs L2 step down toroid DEFINITE Increase
Was doing some work with a simple step down with ferite toroid for fun, and hooked 6, 12V 1Watt bulbs in PARALLEL. The result was significantly brighter output on L2 compared to L1. Parallel…
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…
Don Smith Device Project Part 27: Center-Tap Revival, and Caduceus L1 Resonant At All Frequencies
wanted to show you all something special, i went back to the center-tap, based on Dynatrons work, and used a Caduceus winding for L1. Due to the center being the negative now, L1 needed…
Don Smith Device Project Part 20b: Revised Schematic, Increased Output, and Capacitor Discharge :D
STILL IMAGE OF A CAP DISCHARGE… imageshack.us SCHEMATIC HERE… imageshack.us This was kinda rushed, wanted to have more to show, and thought of more right after, This is no-where near resonance, just used what…
Don Smith Device Project Part10: SYSTEM ON FULL BLAST @ approx 400-1000% efficiency??
so lets say minimum the output is 48VDC x 20A (assuming correct) = 960wa​tts …Input is 110VAC x 2A = 220watts …960w / 220w = 4.36 ( 436 % efficient ) …BUT…if the voltage…
40 Don Smith Device 1/01/13: Dual Quarter Wavelength Step-up Tune and 50 Watt Halogen
Here i have improved the gap further by restricting the break-over voltage to a much higher level before spark discharge event occurs, Done by using the wider surface polished brass electrodes instead of smaller…
Radiant Oscillator Circuit / Don Smith Part 5: 0 Amps X 12 volts =12 Watts ? :) Part 5/
imageshack.us hehe back again, couldnt resist adding bulbs, now there is 12 watts of light in PARALLEL to the output, series connection is not as stable. This is very promising. it reads 0 amps…
Radiant Oscillator Circuit / Don Smith Part 7 A: One Minute Run Time WITH Circuit 1 Farad Capacitor
2x 2n3055 npn bipolar transistors 2x ignition coils with no resistors -Test leads for connections -at least one 12vDC 3 watt led bulb -analog ammeter 0-5 amp (or 0-1Amp would work:) -12 volt battery…
