Using some laser cut parts, along with a handful of machine screws and nuts, wire, conductive tape, and packaged inside a take out food tub, you can make a three axis motor controller.
This controller was created as a super inexpensive, easy to assemble way to operate the SeaPerch underwater ROV. This controller allows you to make your own DPDT switches. You can also make the switch part using a different technique, and more standard materials.
There are photos of this project.
