Note: I have done real damage to my machine during this process - I don't recommend connecting the wiring in my cowboy style! This was intended to be a quick test to see if it was worth implementing in a proper way. But when it worked.. I got lazy and left loose cabling inserted in the port. I'll be getting a male plug for this port and wiring to that instead.
I found some LED strips in the attic that the missus had got for our wedding and I've put them under the window sill and under the back of the A1200 - powered by one of the ports at the back.
I love the outcome and I think it gives it a nice presentation and a sense of an aura around it
