Out of the frying pan and into the fire. Guess I finally got to press the "Panic Over" button to yesterday's problems earlier today and also got to the bottom of a few other issues. But then got my next panic delivered. Three new different circuit designs that have to interwork by last Tuesday.

This is the smaller of the three, possibly the most likely to cause problems! Any Analogue Engineers out there?

Hopefully back by the seaside sometime tomorrow :)
