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.

Since the 1980s, we’ve seen innumerable attempts to revolutionize the way we interact with computers. Since the advent of keyboards and mice, we’ve seen everything from magic wands to electric gloves, with [Deemo Chen]’s project fitting into the latter category.
The build takes on a cyberpunk aesthetic, with addressable LEDs installed along each digit. The various digits light up randomly, and the wearer of the glove must tap a button on the corresponding digit in order to test their reaction times. An Arduino Uno runs the show, and keeps track of the score, displaying the results on an attached HD44870-compatible LCD.
The mess-o’-wires aesthetic, with bare electronics hanging off the glove, goes a long way to making this look like a proper bit of sci-fi kit. The lurid, colorful glow is a key part of this look, and something we’ve seen on many projects over the years.
Overall, the reaction trainer served as a great freshman project for [Deemo], along with their chums [Dhruv] and [Ryan]. Along the way, the team clearly picked up skills in microcontroller programming, as well as learning how to work with LCD displays and addressable LEDs. Master these skills and you can pull off some impressive feats. Video after the break.
