[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.

Hackaday’s very own [Mike Szczys] just shared an awesome binary clock he’s been working on. Unlike a normal binary clock that is only readable by self-admitted geeks and nerds, [Mike]‘s clock is nearly comprehensible by the general population.
There are 12 lines of three LEDs around the face of [Mike]‘s clock. These LEDs represent the time in minutes in binary – the inner LED is 1, the middle LED is 2, and the outer LED is 4. Adding up each of the LEDs around the clock face gives the number of minutes passed since the top of the hour.
To display the hour, [Mike] used a red/blue bi-color LED in the center of each line of LEDs. For example, at 1:03 the one ‘o clock hand will have a blue LED in the first position and a purple LED in the second position. A minute later at 1:04, this changes to blue, red, blue.
If that is a little confusing, there’s a wonderful video demonstrating the pattern of LEDs throughout the hour.
For such an interesting clock, the build is fairly simple – just an ATtiny44 with an STP16CP05 LED driver. Time is kept with a battery-backed MCP7940 real-time clock, and power is provided by a simple USB port.
[Mike] had enough boards manufactured for several dozen clocks, but only had enough parts (and patience) to solder up four clocks. You can check out the time-lapse of him going to town with a soldering iron on one of these boards after the break. As with all good builds, the code and schematics are provided on GitHub if you’d like to make your own.

More old computers on FPGAs!
[Andy] loves his Memotech MTX computer. It’s an oldie with a Z80 running at 4MHz; the perfect target for an FPGA port. The ReMemotech has everything the old one has – cassette interface and all – and can run up to six times faster than the original.

If you’re going to build a jukebox, why not go all out? Here’s a touch screen jukeboxwith an LCARS skin. Yep, the same interface found on Star Trek: The Next Generation.

[McMonster] found a great pair of blog posts (1, 2) showing what ancient ICs look like without their casing. Since these were CERDIP packages (two ceramic plates glued together) they were exceptionally easy to take apart leaving the entire chip intact. Pages are in Polish, but there’s a Google Translate button on the sidebar
Cheap and easy Arduino wi-fi
Quick quiz: what’s the easiest way to get data onto an Arduino wirelessly? XBees? GSM modules? Nope, just get a wireless router and an Ethernet shield. The Ethernet module only cost [Doss] $20, and we’re sure Hackaday readers have a spare wireless router around somewhere.
Chiptunes! Chiptunes I say!
[mdmoose29] has been working on making a custom SNES cartridge for a dubstep artist (tell us more, [moose]…). In his search for programming tools, he found theSNES Game Maker. We tried it out for a bit and it’s still a very unrefined beta. Still, making SNES programming easier is awesome.
You people are awesome. Here’s six things for a links post.
[Valentin] made a night vision monocular from an old VHS camcorder, a small spy camera, and a handful of infrared LEDs. Here’s a video of [Valentin]‘s build in action.
[Blair Kelly] has always been interesting in the concept of Remote Operated Vehicles. As soon as he got his hands on an Arduino he began his endeavor to turn an RC vehicle into a land-based ROV. What he’s done so far is incredible.
Here he’s showing off features of the build using a PS3 controller. But it can also take commands from an Xbox 360 controller or an arcade-style steering wheel. We like the latter the best, which is shown off at about six and a half minutes into the video (embedded after the break). Since there’s a webcam on board, this ends up being a virtual cockpit for the pint-sized car. But it gets better. That webcam is mounted on a servo motor, and [Blair] included controls that pan the camera. This lets the driver ‘look’ left and right. On the front of the vehicle there’s an accelerometer. Data is collected by the Arduino and sent via the WiFly module. This adds rumble to the controller if you’re using one that has that ability.
It’s a big project already, but it sounds like [Blair] has not end of ideas for future versions. Right now he’s planning to increase the overall size which will let him explore places that aren’t as flat as his livingroom.

[DanNixon] has put together this unique interactive table concept. Usually, when we see the term interactive table, we think of an LED grid. That just happens to be what we see the most of. While this table does, in fact, have an LED grid in the table top, it also has several other features and some very nice construction.
Instead of going the usual boring rectangular route, [DanNixon] decided to build a more visually appealing structure. The build log on that part alone is worth a peek. After that, he has a small LCD screen for displaying headlines and song titles as well as a compact LED matrix for some visualizations.
Great Job [DanNixon]
