555 IC Project - 'Red Alert' Siren query.

[Mark Hennessy]

Very nice! Can't beat a PCB, even for one-offs. I used to make them all the time in the past - I'd have designs on the go to slip in along with the prototypes that were required at work. At the moment, what with the kids and various pets, I've decided to not attempt to do them at home - especially now that the prices for professionally produced PCBs have fallen so dramatically. Maybe later - I do miss the process...
