I’ve made a second servo library for MSP430 Launchpad. This one only supports 2 servos, but is far more accurate than the one supporting more servos. The code is on inventortown.

North Face Ultra Trail
A good friend of mine completed the North Face Ultra Trail this year. He’s done a great write-up that really brings the whole thing into perspective. I’m so impressed.
… The longest individual event is also the oldest of the four – and is named after a popular hiking circuit around Europe’s highest peak, Mt Blanc. The UTMB race is “usually” (organizers change the route depending on weather conditions) 166 km long and involves a cumulative ascent of 9,500 meters and the same elevation descent as the route loops around Mt Blanc to finish at its start. To put this in perspective, Mt Everest is 8,848 meters. Although the highest peak is a “mere” 2,537 meters, there are about ten serious mountains to climb (and descend) before making it back to the start line…
3D printed simple biped with 4 servos
Here’s a simple biped I’ve printed using my Makerbot. It’s printed in clear PLA, which I think looks quite nice. The design is rather poor, but it walks ok. This one here runs with a standard radio control, but I’ve tried it with Arduino and Launchpad MSP430 also. Maybe I’ll fix it up to look a bit better.
It uses 4 cheap servos from Hobbyking, and a cheap remote from Hobbyking. You can easily build this robot with wooden sticks or similar, without a 3D printer. There are several examples on Youtube of this. This version is not as complex as my other biped, but this one is much simpler to build (and control). It uses a 2 cell LiPo battery and an ESC to convert down to 5V for the receiver and servos.
