Pendulum Challenge

How are your reflexes? Ken Delahoussaye’s Pendulum Challenge (featured in MAKE Volume 26) is a fun and clever handheld game that you assemble on a printed circuit board. The game’s arc-shaped array of 15 LEDs (14 red and 1 green) simulate the path of a swinging pendulum, which you try to stop at the bottom of its arc through 5 levels of difficulty. A piezo buzzer adds sound effects (which the mode button can silence for the benefit of hard-working parents and studious siblings).

The Maker Shed is brought to you by Maker Media, the makers of MAKE Magazine, the Maker Faire, and much more.

Launched originally as a source for back issues of MAKE Magazine, the Maker Shed expanded rapidly to meet the demand for 'projects in a box,' otherwise known as kits. Now we have a little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .
