@Sanmankl,

I have not done the firmware for the PIC quite yet. But I will in a couple of days. I'm currently soldering together a high speed 6 transistor switch with optocouplers. I have released my drawing on page 1 on this thread! I'm building my switch as shown in that drawing. I have six wires to solder on my switch and then can run a test to see if the switch is working ok. After this test I will start to write the assembler firmware for the PIC. Then I have to solder the capacitor and diode part of the circuit. (Waiting for parts so this will be one of week from now.)

[EDIT] Yes, I will release all information in this forum including the PIC16F84A firmware.

@Plengo,

Bedini did build a solid state circuit back in 1984. He states (in papers and also later on his web site) that this circuit works. I believe him. I have done a careful analyze of the papers and material available to me. My conclusion is that the transformers shown in the Bedini drawing is for controlling the base of the transistors and not for energy generating. Using a transformer like this was a common technique before optocouplers became available on the market. The transformer will insulate the transistor from the controlling circuit just as optocouplers do. So, yes, I do think a solid state version will work providing the switch it self is fast enough. The transistors I have selected is good for up to 30 MHz and that should be enough. If we use smaller batteries (say 9 V NiMh) then the 10 Amp. rating of the circuit will do fine as long as we use heat sink on the transistors.

@ Groundloop,

My good man. Thanks for sharing. I'm "crippled" in terms of electronics and programming (writing code) so your contribution is much valued. That said, I may want to mod the circuit to use a timer chip like a 555 or something similar (TL594, perhaps?).

I look forward to your firmware release.

Holiday cheers, sanmankl

@Groundloop
thank you. Nice code too! Easy to read and very straighfoward.

Fausto.
