Got asked to make some single channel ones, and so was going to build them on veroboard like the first one, however I realised that I could re-purpose my N2HV ESC boards to build the valve controllers on:

Sadly I forgot to take the prototype board at the weekend so couldn't test it (Maelstrom needed one as well so could have got some proper battle testing ), So I still don't know if these will actually fire a Burket, but theory says they should.

In other news, I've got a rough draft of the servo control code working; just waiting on some better chips. If these work well it'll hopefully make the flappy lifters like on Tormenter 3 properly controllable :L
