Nigel is freaking out now.. So this is what they do in there spare time!
Hey, on the good side, my 16F628A chips showed up today, and I am about to go back to assembler (3 weeks of compilers, and I give up). And 12F509 came in too. I should have gotten 12F629, but too late now. And lots of 15-22pf caps and 32K xtals (man are they small)...
Anyway, the BBQ piezo will work great. The push button kind, not the spin with you fingers type.
Also, Aqua-net hair spray, misted in the tube is the best brand... But hair spray works well as a fuel. And people put that in their hair???
Mind you it was years ago, and I did it for "my kids".. That is how I know this.
