A Robot That Funds Itself!
ThunderBird 6 - (aka Mental Detective) should be able to repay its creator for the cost of its creation. This metal detecting robot has a hacked metal detector mounted to a scanning servo which is mounted to a linear up/down stepper motor that allows the robot to roam the beaches autonomously looking for those precious metals lost in the sand.
