In a recent episode of Revision3's The Ben Heck Show, the host teaches viewers how to modify a keyboard to bring the subtlety of analog stick movement to WASD keyboard controls.
In the video, Heck uses rod magnets inserted beneath the keys to broaden the binary choice offered with keyboard input. After his modifications, the keys allow characters to move at various speeds, just like analog control sticks.
Heck used a standard keyboard with a "long throw," meaning that the key travels a distance when pressed. He then tore it apart, modified it using a lot of wires, science and electrical engineering knowhow and put it to the test.
Check out the video above to learn how to make your own and to see the keyboard in action.
