There are many different ways to test one’s reaction times; a simple way is to simply drop a ruler and see how far it falls before you can catch it. Take that same concept to a greater level, and you get this impressive “Catch The Stick” game.
The creation of one [Romain Labbe], the build has a wooden frame that holds up several sticks roughly seven feet off the ground. When the game is triggered, a beeper counts down, and then sticks start dropping. Each stick is held in place with a small solenoid-controlled latch, and the game simply energizes the solenoids in turn to drop the sticks randomly. On easier modes, the sticks are released gently, one at a time. On higher difficulty levels, they’re released in a near-continuous stream that would tax even a team of several players.
It’s not a complicated build, but it is very nicely executed. It certainly looks to be good fun to play with friends. Alternatively, you could try out this more distributed-style build. Video after the break.

In many sports, it’s important for competitors to be light on their feet, and able to react quickly to external stimuli. It all helps with getting balls in goals, and many athletes undergo reaction drills as part of their training regime. To help with this, [mblaz] set out to build a set of reaction trainers.
The training setup consists of a series of discs, each with glowing LEDs and a proximity sensor. The discs randomly light up, requiring a touch or wave to switch them off. At this point, another disc will light randomly, and so on.
The discs are built using an ATmega328 to run the show, with NRF24L01+ radios used to communicate between the modules. High brightness red LEDs are used for indication. An optical proximity sensor is used for its fast reaction time and low cost, while power comes via a small lithium polymer battery integrated into each disc.
We’re sure [mblaz] and his fellow athletes will find the rig to be useful in their training. There’s plenty of scope for electronics to help out with athletic training; this boxing trainer is a great example. If you’ve got a great sports engineering project of your own, don’t hesitate to send it in!
