I decided to spring for one of the expensive Firgelli actuators, and just gave it a quick try. I either got a broken unit, or it is the worst piece of junk anyone has ever made for NXT. First of all, you command it to move a distance, not command it (...) (14 years ago, 25-Jan-11, to lugnet.robotics)

Dear Brahm, We know we are not supposed to do this on this forum, but we shall do it anyways because our gratitude towards you is more intense than just a 5 star rating.

(...) No, purely resistive. Although it does have a "boot up" time, I think it's just due to heating up the element. I'm not completely sure if the element will respond better to a "dimmer" type set-up (running it at less than normal voltage) or a (...)
