The circuitry seems very similar to the commercial Spitfire so should be good.

It looks a great design, not that I can claim to understand it!

If anyone fancies having a go at making the PCB, the artwork for the mask, correctly sized, is attached.

I make the number of 0.8mm holes that need to be drilled as being 225.

Having drilled more than 1,400 holes on sixteen Mini-Mod PCBs in recent weeks, I'll sit this one out!
