This is another useful device brought to you by the students from Killer Bees Robotics: FRC Team 33.
This Instructable show how to create a handy motor testing device for Robotics Development. Every team should have one of these tools. It is incredibly useful and can be made for next to nothing out of stuff every FIRST team probably has laying around the shop. We have had one of these for years and use it daily. It allows you to safely do motor testing without needing a control system or speed controllers and allows you to reverse directions easily without swapping wires. I couldn't build robots without something like this.
We call device this the "Phaser" around the shop because it looks like the Phaser guns Capt Kirk and Mr. Spock used on the original Star Trek series.
