I had left last night at the point of fixing on the controls.
The buttons were in place so next up were the LED's.
The Red LED in the centre of the board can be used to trigger the photocell so this has heatshrink round the legs. Notice that one leg is longer than the other to indicate positive and negative, the positive being longer. This is generally indicated on the PCB by the silkscreen square symbol around the hole.
However on for this LED the symbols is slightly different. It is the actual symbol used for a Light Emitting Diode (LED) indicating anode (positive) and cathode (negative) with power or light emitting from the lamp. The current flows from positive to negative.

Ok, just realised the time and I have to clean my teeth. Leigh is playing with his new toy now. I has a good range of tone and he is coming up with some great melodies, sounds awesome through a delay!
To be continued...
