Playing video games on your office phone

So IT has your computer locked down, but if you’re lucky enough to have this model of telephone you can still play video games while at work. [AUTUIN] was at the thrift store and for just $8 he picked up an ACN videophone on which he’s now playing video games. We don’t know what magical second-hand stores sell functioning electronics of this caliber  but you should never pass up an opportunity like this.

It turns out the phone is running Linux natively. After some searching [AUTUIN] found that it is possible to telnet to a root shell on the device. Doing so he was able to figure out that the phone uses standard packages like ALSA for the Audio and /dev/input/event0 for the keypad. It even includes an SD card slot so he loaded one with a Debian image and used pivot_root to switch over to that OS. At this point the phone is his to command and of course he loaded up a video game which you can see in the clip after the break.

Bitbanging Super Smash Bros.

[Kyle] and an a few of his classmates are wrapping up a microcontroller interfacing class at Purdue and thought it best to send in the results of their efforts. It’s a version of Super Smash Bros. made by just bitbanging pins on a microcontroller.

The hardware for the project is based around a Freescale 9S12c32, an updated version of the 30-year-old M68HC11 microcontroller. For the controls, the guys used a Playstation 2 joystick and buttons housed in an Altoids box, and the actual console is made out of strips of wood stapled together to look like a crate from Super Smash Bros.

There are nine playable characters:  Pikachu, Captain Falcon, Yoshi, Donkey Kong, Mario, Luigi, Link, Kirby, and Fox. Despite these characters being only four pixels high, the game looks extremely playable (at least when two players don’t choose the same character). After the break is the video demo of Super Smash Bros: Bitbang edition, along with a gallery of pics showing the console and gameplay. All the code is up on GitHub for your perusal.

Soccer simulator rules a child’s birthday party

Being a dedicated father, soccer coach, general tinkerer, and electrical engineer, [Dave] decided to build a soccer simulator video game for his son’s 6th birthday party. The concept behind the game is to put a soccer ball on a tee and have an eager line of six-year-olds kick the ball into the goal. A video of a goalie is projected behind the net, and sensors in the goal will determine if the player scored a goal or not.

The first part of [Dave]‘s project was getting footage of a goalie diving for a soccer ball. Luckily, [Dave] is friends with [Mark Macdonald], a former NCAA goalie. After 10 minutes in the park with [Mark] and a 720p camera, [Dave] had all the footage needed to build his video game.

To detect where the soccer ball passed into the goal, [Dave] built a small soccer goal studded with infrared LEDs and infrared beam break sensors. Combined with a small switch underneath the ball tee, the software knows the time of flight and where the ball crossed into the goal. The game processes these two numbers to determine if it’s a goal, or was caught by the retired pro goalie.

The kids at the birthday party lined up to play [Dave]‘s soccer game – a huge achievement getting 6-year-olds to wait their turn. We admit that we’d like to have a go at this game, although we’re pretty sure we saw an arcade version of this game years and years ago.

GeneBoy is the portable Sega Genesis you’ve always wanted

geneboy-portable-sega-genesis

There’s something about portable gaming systems that just doesn’t get old. Perhaps its the nostalgia, or the unique cases and form factors the modders come up with. Whatever it might be, we think they’re great.

[Downing] wrote in to share a portable system he just wrapped up, called the GeneBoy. He broke down a Sega Genesis console to the bare necessities, then attached a 3.5” backup camera screen to serve as the display. A 3rd party Genesis controller donated its buttons to the GeneBoy, while his D-Pad was salvaged from an original Playstation controller.

The case was built from vacuum formed plastic, which made it easy to get just the size and shape he needed to hold everything together perfectly. Even though he says that the outside of the case got a bit roughed up during final assembly, we think it looks great. I would certainly enjoy having all the fun of [Sonic the Hedgehog] or Road Rash in the palm of my hand any day!

Pick up that can, [Jeri]

We all need an excuse to play Half-Life 2 sometimes. [Jeri Ellsworth] put together a My First Crowbar controller to throw a few headcrabs across the room. It’s pretty much Half-Life 2 for the Wii.

The build is very simple – just a tilt switch hot glued to the underside of a childs-size crowbar. Two leads go from the tilt switch to the contacts on a (PS3?) controller. All you need to do to attack is swing the crowbar wildly.

[Jeri] has us wondering what other awesome game controllers could be made. Of course we’ve been wanting a real-life Gravity Gun or Portal Gun for years now, but right now we’re thinking about a real Katamari. We might need more hot glue.

As far as building our own, we’re thinking about using one of the Cheap DIY tilt switches we saw the other day. It’s a simple build, and sure looks like a lot of fun.

No quarters required for this sidescrolling game in a box

teagduino_game_in_a_box

[Adam] from Teague Labs wrote in to share a new gadget they built to help demonstrate the capabilities of the Teagueduino. Their table top video game in a box was made with a bunch of electronic components they had sitting around, as well as soda straws, plenty of painter’s tape, and some popscicle sticks.

When someone pulls the string on the front of the box, a servo opens it automatically, and a second servo starts spinning the game reel. As the reel moves, the player is presented with a set of obstacles to dodge, guiding the “hero” via a knob-controlled servo. A hall sensor attached to the back of the character is tripped when passing over any of the obstacles, which are attached to the reel with magnetic tape. When the hero collides with an obstacle, the game ends and proceeds to close itself, much to the chagrin of the player.

As you can see in the video below, it’s a pretty entertaining and challenging game.

Looking to make one of your own? Swing by the Teagueduino site to grab the game’s code and be sure to share your creations with us in the comments.

Overclocked ATmega32 gaming

With more pixels and more objects to track you’re going to need to get that AVR running pretty fast to get the job done. But [Vladutz2000] figured why stop at 16 MHz when you can overclock an ATmega32 to 27 MHz for a faster gaming experience?

This build may not be as colorful as Super Pixel Bros, but choosing a KS0108 graphic LCD certainly brings a lot more definition to the images. You can see in the video after the break that the AVR does an excellent job of generating and animating multiple objects. It doesn’t take much to put this together yourself but if you want the board layout done for you, you’re out of luck. The hardware for the project is installed on a PCB that was hand-drawn with an etch resist marker. Continue reading “Overclocked ATmega32 gaming”
