Now and then, I am tinkering on a set of a Clone Trooper armour (Star Wars). The armour should contain a comm pad on the right wrist, with a couple of buttons on it. Most clone costumers/cosplayers buy a simple plastic or rubber cast commpad. I have acquired a small keypad with buckling rubber sleeve switches that I intend to rebuild. At first I had planned to cut some tiny function keys from a used laptop keyboard, but it looks like the keypad would be easier to use since it is plastic and the keys are in two rows already.
