Dr. Boardman’s Color Conundrum

March 8, 2010 by Mike Szczys 19 Comments

We feel like trumpets should be sounding. Someone took the overused project of connecting RGB LEDs to a microcontroller and produced something useful. [Paul] created Dr. Boardman’s Color Conundrum which works much like a simple mechanical coin-op game you might find at a carnival. When switched on, a random color is displayed by the ping-pong ball covered LED on the left. The player then manipulates three knobs to color-match the two lights.

Inside you’ll find a minimalist set of hardware. An ATmega8 polls the three potentiometers and uses them to mix the appropriate user color. Everything is wired-up using prototyping board and draws power from two AA batteries. He’s using a random seed stored in EEPROM and increments it every time the uC boots up. This keeps the input color different for every game.

Fun and simple, it’s not going to make your guests marvel at the complexity but [Paul’s] come up with a unique game that we think has marketing potential.

Using Mindflex To Shock The Heck Out Of People

March 4, 2010 by Mike Szczys 29 Comments

We love to see eloquent hacks but this isn’t one of them. [Aaron] and his fellow sadists are using a Mindflex game with an electric shocker. If your brain is idle you’ll be fine, but too much activity inside the noggin and you’re in for nasty shock to the arm. Take a look at the video (bleeped but probably NSFW) after the break.

We’ve seen the Mindflex before, they’re using its interface in the same ways we’ve seen the Force Trainer used, by tapping into the LEDs. The shocks are provided by a Qkit, so hopefully there’s enough engineering behind it to keep the ‘contestant’ safe.

Hey, isn’t that the Tron Guy?

Bring The Crane Game Home

February 24, 2010 by Mike Szczys 25 Comments

Everyone’s familiar with the quarter gobbling crane games. More often than not there’s a child nearby begging a parent for more quarters so they can try their hand at the toy-snatching claw. [Marc.Cryan] put his quarters to a better use by building a home version of the crane game.

[Marc] installed a gantry in an archway of his house. The crane trolley rides on this gantry and uses a spool to raise or lower the tether for the claw. Winning copious style-points, he used the case of an old mouse to form the claw. An Arduino controls the different motors in the system and a toy was repurposed to act as the controller. As you can see after the break, it’s more fun than the cinema-lobby version of the game and your kids can play with it for free.

Sukhoi Su-27 Jet Build Throws Down

February 18, 2010 by Mike Szczys 53 Comments

This no model, but a fully functioning RC jet. The Sukhoi Su-27 was the Soviet Union’s counterpart of the F15 and this 1/6.5 scaled version measures eleven feet long and is fully controllable. As if the 80-page build log wasn’t enough, the flight video after the break is nothing short of jaw-dropping. The test flights end in smooth landings but with all the time that went into the project that’s got to be nerve-wracking.

The Mini-Markade

February 16, 2010 by Caleb Kraft 28 Comments

We love arcade games. Who doesn’t? We feel that the “arcade” feeling just can’t be replicated in any other form factor than an arcade cabinet. [Moslevin] must feel the same way too. He has built, what could possibly be the worlds smallest arcade cabinet. Aside from a coin mechanism, it is fully functional. It is an ATMega328p running his own custom software. The games he has available are Tetris, Invader, and Breakout, all coded by himself as well. We’ve seen small arcade cabinets before, but none this small.

Adding Words To Catch Phrase

February 16, 2010 by Mike Szczys 23 Comments

[Brandon Meyer] spared no expense in modding the Catch Phrase game to use custom word lists. The altered version of the game, normal sold for around $25, now comes in at a whopping $230! That’s because the internals were gutted and replaced with an Arduino, 20×2 LCD display, and some other interesting bits. The device now features an SD slot for storing your own lists and a USB port for programming.

At first glance we were hoping some simple EEPROM hacking had unlocked the secrets of the device but that wasn’t he case. We’d love to see some more economical versions of [Brandon’s] prototype. Perhaps reusing the original LCD, replacing the Arduino with the ATmega168 that makes up its core, and using a diy SD cradle for a card reader.

So yes, this version is a bit of overkill but still very nicely done!

[Thanks Zoidberg]

Hexacopter

Quad copters have been pretty popular for the last few years, but this one is new to us. Take the same basic layout, but bump it to 6 rotors. Then you’ll have the hexacopter (google translated). With 6 rotors, built in GPS and stabilization and a camera mounted on the bottom, this thing is pretty well equipped. You can see how agile and stable it is in the video above. We know it isn’t necessarily new, but it is new to us. Of course, you don’t have to stop at 6 rotors. You could always just continue on to 8.
