Hi friends, I'm a user of Meade's 12" LX200GPS and I was looking for the software to connect my telescope to my pc, I installed "Starry night pro" version 4.5 and ACP3 but they didn't work. Starry night only had LX200 & AutostarII in the list it supported but not LX200GPS. Does anybody know...

Hi I am currently working my way through a control systems textbook and I am bringing my understanding of the relevant mathematics up to speed. I have happened across the Laplace Transform which I am happy enough with. I am concerned however that given the fact that this is a real project I may...

Hi, I have a submerged magnetic water pump that is pushing too much water at 8500L/hr. I know that the propeller rpm depends on the frequency of the AC supply but how can I build a simple circuit to reduce the frequency? Thanks :smile:

Hi, I'm an undergrad major in electrical engineering and physics; I am also minoring in mathematics. I am thinking of going into the field of control theory. I was wondering what branches of mathematics are particularly relevant to the field of control theory (I had a mathematics professor who...

Been brought to my attention in another topic, so just how is it that technologies suck as traction control make a formula 1 car harder to drive? This is directed at Mr Robin Parsons, but obviously anyone can join in.

Hi I was wondering if anyone knew of any good tutorials on modelling control systems - I have to convert a RCL circuit to a control system - i understand things like how to express components mathmatically but am confused as to steps I should take to make sure I do a thorough model? Any...

You have a right to petition, this right can also be done far more effeciently over the internet at petition.com-in theory this would be a free website where people could freely and reasonably discuss the issues and for once the common man and women would have a chance to let there particular...
