A weak introduction to the Dynamixel AX-12A servo. This is an intelligent servo that uses digital communication rather than the usual PWM I will follow up shortly with a better example project.
Ohh, I *loved* to see a HP41 on yor desk! After a number of years collecting dust I got around switching batteries in mine to new rechargeables in the battery pack. So, now my trusty HP41CV with various eproms (one of which I actually developed myself) is in my office beside the computer. It is truly amazing the lifetime you get of these old HP stuff... The HP41 was and is one of a kind.
