After an immensely frustrating several days, during which I have taken the organ to pieces, unit-tested things which were known to be functional years ago, replaced reed switches, drunk lots of coffee, cried extensively, taken my shoes off and jumped on them, and basically been a drama queen, I have learned two important lessons.

Lesson 1: An oscilloscope would be a good investment.

Lesson 2 (which would have been learned more quickly if I had observed lesson 1): establish a good ground.

More to come, at some point, when I’m not so cross. Also, I need to tidy up a bit.

Also, why does my dog keep trying to eat lumps of wood and bits of wire? It’s not like he doesn’t have a whole box of toys and far too much food…
