Adding Digital Game Indicators To A Neo Geo Arcade Cabinet

January 19, 2012 by Mike Nathan 14 Comments

neogeo

[George] is a Neo Geo aficionado, and among his collection of paraphernalia, he has a MVS-Mini game console. His mini “Multi Video System” is a 2-slot model, meaning that it can hold two game cartridges at a time, which are indicated by plastic cards inserted in the cabinet’s face plate. Instead of swapping those cards out each time he changed cartridges, he thought it would be far cooler to install digital displays instead.

He scoured just about every retail store he could before finding a handful of small 5” digital picture frames that looked to fit the bill. After some careful cabinet modifications he had them wired up and ready for display. The frames don’t hold a ton of pictures, but they do support the use of SD cards. [George] says that he’ll likely just buy a ton of small SD cards, swapping them out whenever he changes games, though over time that might become as tedious as swapping out the plastic cards.

We would love to see [George] take his new digital display up a level, so be sure to share your ideas in the comments. Perhaps we can persuade him to automate things a bit.

Augmented Reality Using Pez Dispensers

January 17, 2012 by Brian Benchoff 4 Comments

[Johan] really got himself out of a bind with this one.

After his son started playing AppMates, he desperately wanted the requisite figures to complete the experience. AppMates is an iPad game where a child drives a small plastic car around a virtual environment displayed on the touchscreen. Unfortunately for [Johan]’s son, the officially licensed Cars characters would take at least three months to make it to his home in Sweden. [Johan] did the next best thing and made his own.

[Johan] took a pair of Cars Pez dispensers and took off the figure. The bottom of the character was covered with a bit of plastic from the base of the Pez dispenser and a little bit of conductive foam and was added to the body. Now [Johan]’s son can drive his toys around Radiator Springs just like he could with the official figurines. There’s also the aspect of not making a child wait months for a bit of plastic, so we’ll call this one a win for [Johan].

Power Wheels Jeep Makes An Awesome R/C Car

[Will] from RevoltLab wrote in to share part one of a cool project he is working on right now, a remote-controlled mobile rocket launcher. Before you run off and call the Department of Homeland Security, he says that the launcher will be used for personal hobby rockets, which are typically considered mostly harmless.

The first part of the build is mostly concerned with obtaining a Power Wheels car and tweaking it to be driven remotely. After stripping out most of the odds and ends out of a Barbie Jeep he found via Craigslist, he added a small hobby servo under the dashboard to actuate the pedal. A larger (and much more expensive) servo was attached to the Jeep’s steering bar, allowing [Will] to easily turn the wheels with the flick of a switch.

With the mechanical bits out of the way, he installed an R/C receiver and took to the ~~streets~~ lawn with his creation.

The car seems to handle pretty well, and although the price of the components quickly start to add up, we’d be more than happy to spend that kind of cash for an R/C car that size!

Continue reading to watch a short video of the Jeep in action, and be sure to check Revolt Labs’ site often to follow [Will’s] progress.

Matchbox Launcher Reacts To Emergency Band Radio Dispatcher

January 11, 2012 by Mike Szczys 15 Comments

[Jeff] and his wife put together a firefighter themed birthday celebration for their son. As he’s not entirely handy in the kitchen, [Jeff] decided not to lend a hand with the baking or cake decorating. But he didn’t forego the opportunity to combine a couple of different projects to make a Matchbox car launcher that responds to emergency band radio.

Since he’s an amateur radio enthusiast he already had a scanner to monitor the air waves. Apparently there’s a band just for relaying dispatch messages to emergency vehicles. He set the radio equipment to only monitor that channel. An Arduino was added to the mix, taking measurements of the voltage level on the scanner’s audio output. When it’s driven high enough the Arduino trips the toy car launcher.

The car launcher itself is a pretty nifty setup. There are five chutes at the top of a ramp that each fit a car. A sliding gate holds them in place, but can be removed one slot at a time by a geared motor. The addition of a poster board facade and two flashing red LEDs makes the setup look right at home with the other party decorations.

See a call come into the station in the clip after the break. We don’t have a category called “fun parenting” so “toy hacks” will have to do.

[Alex] Shows Us What Happens When Dance Dance Revolution Meets Simon

ddr-simon

[Alex] was digging through his closet and came upon an old PS2 game pad for Dance Dance Revolution. He hated the idea of throwing it out just slightly more than the idea of playing DDR again, so he decided to find a way to reuse it.

He was a big fan of the game Simon (aka Genius) as a kid and thought that the DDR pad would make a novel interface for the classic game. Using the PS2XLib by [Bill Porter], which allows an Arduino to easily communicate with a PS2 controller, [Alex] put his Simon replica together in no time flat.

He painted an empty ice cream container with the classic Simon colors, installing a small LED under each quadrant, then wrote the game’s code.

As you can see in the video below, his version of the game works nicely, and forces you to actually get up and move a bit, which we like.

A Little Simon Clone Named [Nomis]

January 6, 2012 by Jeremy Cook 3 Comments

[Chris] has been hard at work building his own version of Simon called [Nomis]. Although [HAD] has featured an ATiny Simon clone before, the article does an excellent job explaining how the system works.

The ATTiny85 is used to control this game, which, for now is laid out on a simple breadboard. A PCB version of this game has been ordered from [Seeed], so be sure to check back to see the results of this forthcoming upgrade. It’s really cool that this kind of small scale manufacturing is available to the masses.

A parts list is provided as well as a code overview and schematic. To see it in action, check out the video after the break. There’s an explanation at the beginning, but skip to 1:55 if you’d rather just see the machine in action. The game can reportedly run until a 100 “move” limit is reached. This was arbitrary, but it should be enough for most people! Continue reading “A Little Simon Clone Named [Nomis]” →

OK, You Might Not Be Paranoid – Perhaps That Priority Mail Box IS Spying On You

[Thomas Renck] recently picked up a 1000mW wireless video transmitter that he ultimately planned to mount in an RC plane. Before he strapped it on a plane to potentially kiss it goodbye for good, he wanted to play with it a while to see what it was capable of.

After a friend helped him determine the camera’s maximum range (about 1900 feet on open ground), he thought it would be fun to strap it on his nitro R/C truck. That didn’t work out so well due to some vibration issues, so he constructed a makeshift R/C car from the shipping box the camera arrived in, along with some other odds and ends.

As you can see in the video below, the propeller-driven “Boxmobile” zips along quite nicely. The video feed from the camera is pretty impressive too, allowing him to easily guide the car while it’s well out of sight.

At nearly $350, the self-proclaimed “ghetto-bot” is certainly not cheap, though we hear body repairs are a piece of cake!
