Stivep1: Tesla Rehash (Akula device)

[Hope]

that is nice schematic.c thank you for  help.
I have much more to say  but for now  I'm so busy with other things
I'll be back soon with more

Instead of all this signal generation device,  can we not just digitize the signal and exclude 2/3's of the circuitry?


One good outcome was the output signal from this is it cleaned (rattled) my flue pipes without the taking them apart. Though I did have the whole loose creosote from all the pipe fall into my stove.  This was easy to clean out, thank you for a side benefit!!

I was studying Akula0083's latest posted controller and could not find a local (USA) source for the (K555TB9) flip-flop (chip), but was able to find what I think is a suitable substitute, which is a 4027 Dual JK Flip-Flop. Below is some information on both chips. I'm just presenting this information for review, in case I am missing something, or if anyone has another alternative or suitable substitute.
(NOTE) Of course the pin assignment locations are different, but I look like both chips function the same....?

THe logic table loooks different.  R S and S_{o and Co are marked as H H and L L with the transition chart.... So I think one's backwards... inverted}

Hi-There

Use 74HC112,54LS112,74LS112-depending on your PCB rail power- it is Negative edge trigger JK Flip Flop and exact pin configuration as K555TB9

Hope it Helps

Thank you: myenergetic and d3xor for the information and feed back:
I think that I am going to try to do a board layout and build, but wanted to be reasonably sure that I had, or could get all of the components first. I will post the layout when I get it done.
As always; Thank You and Have a Great Day. br549
