I dismantled the flashing ear-tunnels today and started again with them, going back to the original plan of getting a tri-colour light controlled by TV Remote signals. Well after a lot of cocking about its working. The arduino (on the right of the picture) is sending RC5 codes to the AVR in the middle. Each of the 3 lights has 4 brightness settings (controlled with fake PWM as the AtTiny only has 1 timer) and can be set individually. Once the three colour LED arrives I’ll add it and find a way to package it neatly behind my ear.

Been back on the t-shirt printing too

Oh and I’ve had a go at designing an Ambigram

this should look the same upside-down
