Hey guys, new to the forums. I've been inspired to try and make an Iron Man suit because, let's face it, who doesn't want to be Iron Man LOL. But seriously, I've made the helmet and such, but I was more intrigued at how people got their faceplates to open electronically. I am completely lost in the electronics department, so my question is what do you need for the motorized hinges? I read something about getting a servo...then I got lost LOL. Can someone explain what I need and where I can buy the stuff?
