Hey everyone. I'm currently working on my project (PPCID) and I've come to a dilema. I have a helmet (It is a 5 pound ugly looking helmet) that I'm wanting to be able to move horizontally ontop of my case, but what can I use to make it move? I'm also wanting to make the bottom half of the helmet slide vertically on the front of my case so that when I flick a switch, the two parts slide and meet on the case. If anyone has any idea of what I'm talking about and could help me out with this, then that would be great!
