Whoa! It's 9 AM, do you know where your servos are? Hardly a week goes by that you don't read about a servo from a good family that gets in trouble with the laws of physics. Oh sure, their designers taught them all about duty cycles, but some servos have poor self control loops and demand wider and wider pulse widths, until one day they connect directly to Vcc and end up in the gutter, carrying on about how back in their days, insulation was considered a luxury, and REAL motors were synchronous to 60 Hz.
You better find those little babies and give them some PWM love.
(P.S. - as a C programmer, I'll be slow to use your Python library. Someday I'll break down and join the popular kids crusing down Python Highway, but for now I'll keep bumping along the caverns of C.)
