It's not that we haven't seen a one-handed controller before -- we most certainly have -- but the only significant one on record was done by one Benjamin Heckendorn, the greatest modder of the modern era. In other words, whipping something like this up takes more than a strong will and a boatload of vacation days, making Hasse's hack all the more impressive. As the story goes, his brother is incapable of playing video games due to needing two hands to work the controls; rather than chalking it up to tough luck, this guy completely re-engineered a GameCube controller for single-handed operation. After cracking it open and relocating a few bits and pieces, he then shoved an ATtiny44A, an accelerometer and a digital-to-analog converter within. Crazier still, he even included a toggle switch to select the analog stick or D-pad, depending on preference. Head on past the break to see this thing in action, and tap that source link to leave a handful of kudos.
