I did an HID mouse demo last week using two potentiometers and two buttons. It worked out fine but was really difficult to use as an alternate game controller. I found a thumbstick module and it worked so much better than the setup I had. I wanted to mount the thumbstick module onto something to make it easier to handle. I looked around in the house and found this perfect empty chocolate container. The shape of the container provides a firm grip for my triggering hand.
