Tesla Switch need help

[sanmankl]

@The One,

Attached is MY control circuit. I will use the "old" and faitfull PIC16F84A micro controller.
Firm ware not done yet, this will come later. Full CAD drawing available if you want that.

Groundloop.

@ Groundloop,

I too, would like to replicate this switch. I have all the parts (including the PIC chip). If you are ready to release the software, I'll build it.

Cheers, sanmankl.

@Groundloop,

good do see you here too.

would you share, once it is completed, your design so that I could build one and play with it too?

Do you think that the solid state would be equivalent to the physical switching like relays (I know relays are horrible in timing and synchronization)? The physical contacts cause sparks that It seams they have some secret sauce there.

Fausto.

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.

hey, good luck 

be aware that transistors are often able to handle "high" clock rates but optocouplers maybe not ...
and yes, the coils are for physical seperation equal to optocouplers.

Bedini also says that he needs a lot of time to get his cigar box thing working, finetuning, time and knowledge what effect should happen hepled him ... -> will be hard work 

It's ok to build the switch directly if all parts are available, but if not it is more wisely to reproduce some mueller/bedini tests before ... e.g. try to reproduce the bright white spark with two batterys and fast switching (see mueller document)

For the microcontroller; use of RS232 and pc-software to set clockrates could be helpful 

Best regards, Super
