Look up and down to move up and down, hold the trigger to drive forward. I know there are already a few of these out there, but this one is mine. It features a double-click switch to reverse and a dead space in the middle for limited up-down looking without actually changing the ballasts.
Also has motion sensor input for periscopes. When you click to use a periscope, it pulls you off the ground. Coupled with a motion detector and an edge detector, you can release and re-grab the periscope as an additional input. Why is this helpful? I have no idea yet, but I'm sharing it anyway.
Uses a double click switch from 自由の代償
