I will obviously be calling him Grundels from now on ;D or something similar...
While reading stuff in the web over the past few days while trying to get my head around what I actually want to try - I have seen LEDs that have more than one colour, by having more than one element in the LED itself and 2or 3 additional anodes with one cathode (or might be the other way round, don't shoot me!) which has got me thinking that a flickering circuit could be done with just a single LED...
I am now trying to find where I spotted it. :-[
Found some - red/yellow single LED for the princely sum of £0,10. There are many types, unfortunately some of the colour varieties are only available in SMD, not through hole.
SMD = surface mount device, the kind assembled by robots that light up mobile phones etc.
Through Hole = the ones with legs!
