Goal: to make a piano hammer strike with just the right amount of attack. Four iterations here. The last one posted first and the first one posted last.
v4 Just right? (shorter ramp)
v3 Nice attack achieved by speeding up the servo in one direction. (tall ramp)
v2 Here I made the ramp taller. But no change in attack.
v1 To be honest, this isn’t really version one. It took me a few tries just to make a ramp that the hammer would not get stuck on.
