The gizmo is powered by an ATtiny85 microchip and features a 0.91-inch OLED screen. Four soft-click buttons flank the screen (two per side), and it’s all powered by a single CR2032 coin battery. A small power switch is positioned on the bottom edge of the handheld. The whole thing measures just 1.58 inches wide. The handheld’s creator says your high score is saved when you finish a game but if you power down before completion, your score will not be saved. The system’s Arduino source code has also been made available for anyone wanting to take a closer look.
