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

[youtube=http://www.youtube.com/watch?v=gKACRU4LKfM&w=470]

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!

Continue reading to see the GeneBoy in action, and be sure to check out [Downing’s] blog along with the Modded by Bacteria forum thread where he discusses the finer details of its assembly.
