I tried the "one pin sketch" and it worked with the higher BAUD. It was probably the wrong BAUD fault for the garbage in the original sketch. I see what you mean for the trollmaker sketch, your seems much precise and it uses 15% less memory.
So stupid of me, not looking enough careful at the sketch.
