basically im working on a case mod which i am currently using servos to contol various moving components on the case, but i run into the problem of how to get various events to happen at start up and shutdown. i know it must be simple but i cannot figure it out. also triggering events based on temperature would be nice too.

you could use a microcontroller such as the Picaxe 14M and set it up so that it had a thermistor attached for the temp controlled events, and have it setup to run the startup events as soon as it was turned on. As for shutdown events, if you ran the microcontroller of the 5vsb rail on you psu then you could use a transistor to short an input to 5v when the computer was on and have it setup so that when this went low it activated the shutdown event.

If you need any directions on how to do this, just ask, I'll be happy to write the code for the picaxe and draw schematics etc.

I think smray's got the simplest way of doing it. Alternately, you could get a computer controlled servo controller and create system events at various points to do what you want. Depending on your experience and what all you want to do, one will probably be easier than the other to implement.

I'd love to see the whole thing, cpt_jr; you should start a worklog in either the 'works in progress' section.

BTW, welcome to TBCS, both of you. I hope you enjoy it here.

shure schematics would be helpfull. how many moters/servos could i control with it? (i need at least 3) could it also double as a fan controler being that it has a temp sensor?

PM renderman, or have a look at his worklog for moterized madness, its in the features worklogs section i think, he explains how to do that in there, he's done it himself
