Hi Yucca

I have a micro electronics background from the 80's LOL so a bit outdated.
I have used C but normally for simple things like this i will use machine language and already have all the PIC development kit so will probably go with these as they come in anything from 6 pin upwards at very low £1-£2 prices.

I also was a Z80 pro  and designed quiet a bit of film animation equipment using them, shame really it's the one micro i have never returned to but have always loved the code structure of the good old Zilog chip.

I was a one man proto devolper at one point and always proto on my own pcbs, very fast turn around and a lot neater than breadboard ect.

Yes of course, go with the PIC, fastest if your already geared up. Oh yeah! Z80 was nice and clean and logical the registers were easily remembered and well organised. I only work in C and C++ nowadays. Do you have your own PCB fab facilities?

edit: forgot to mention, I was in industry for about 5 years as an embedded software engineer, I was writing upgrades (adding GUI screens) and fixes for machines built in the 80s so lots of z80 and 68HC11 work. Now I'm self employed PC software developer so embedded only used for hobby projects.

Yer i have an amateurish light box and a tray for my devolper and acid LOL.

But with cad it's easy to knock it out fast, and if there are errors or design changes then there's easily a version 2, i tend to use mostly SMD these days because you can buy the res and cap kits for £20 and you have nearly all the components you will ever need all in a small compartment traym, also some of this stuff like my last Pulse controller worked down to 250ps res with fast rise times and it would be impossible to build without double sided pcbs and a ground plane.

I really do recommend anyone to work this way it's the only way to proto from my experience, you can spend ages getting a RF circuit going on plug board, but would never be in a position to transition easily to pcb because of the stray cap ect, and vero and breadboard is a nightmare if the circuit has buses or complex wiring.

Almost, I have a bridge coming off the driver which changes it to 645vdc (around that anyways) so the spark gap is dc.  As for the neon it is pluged into empty rails that are not connected to the circuit soooooo it is lighting off an interaction with my finger.  I I do not touch it, it will not light!

Thanks.

Secondary cap is now confirmed at 0.047 6000 VDC

I can see 0.047 mF but to my eye it looks like 8000 VDC. Maybe you eyeballed it better from another angle though? Not that it matters as much, it's the capacitance val that's most important.

Thanks.

That's it xee...perfect
