Hello! some time ago, I converted a counting tube with a simple spin-circuit from http://www.electricstuff.co.uk/dspin.html into a status-light for an old hifi-amp. However, i recently came across this: http://www.youtube.com/watch?v=N5CIIq_ibaI Needless to say, that i want this too ;) Can anyone help me with that? I am used to Arduinos et.al. and i have basic electronics skills. However i lack the experience to do this quickly and properly. Thanks a lot for all input:
