Cheating Relays?

[iainpunk]

sorry for my 9-year-old-ness. I'll eventually come around.

don't worry, we all have those moments.

i regularly forget first order LPF and HPF formulas, and for the LED pinout, there is a trick, there is a rim around the base of the LED, it has one side, that side is the same as the indicator band on a diode (ignoring Russians, of course)

cheers, Iain
