Thanks Raf, that means a lot. I have the same procedure on the other hip 2 years ago and it was 3 months before I was up and moving without crutches. At least I will have time to work on some more circuits and some arduino sketches.
So give me your honest opinion (I can take criticism), what do you think of the TF kit? Anything I should change? I can probably lower the brightness of the GOW bulbs with a resistor, I just have to figure out the value.
