Yep, I'm fairly right on the LED, as you've both said it only works the right way around & you can't really go wrong unless you put too much heat thru it when soldering, or if you apply too much voltage.
I'm cool with using batteries, they're convenient & will last for ages in this application - but did I do my sums right (3 x AA @ 1.2 volt = no resistor?)
Cheers & thanx again
