A Gamecube And N64 Console Mashup

January 2, 2013 by 4 Comments

[Hailrazer] over on the Made by Bacteria forums was a bit tired of all his consoles cluttering up the space underneath his TV. No worries, though, because it’s actually fairly easy to combine a Gamecube and an N64 into one system that looks very professional.

While [Hailrazer]’s Gamecube was left reasonably complete, not including the addition of a mod chip and SD card to hold Gamecube disk images, the N64 portion of the build required quite a bit of hardware hacking. After finding a Game Boy Advance player for a Gamecube – a neat hardware add-on that allows you to play GBA games on a Game Cube – [Hailrazer] thought he found the perfect enclosure for an N64 case mod.

The guts of the GBA player were thrown out and the guts of an N64 were carefully filed down to fit inside their new home. An Everdrive 64 holds almost every US N64 release on an SD card, making access to the cartridge port unnecessary.

A switch on the side of the Gamecube toggles the video and audio output between the Gamecube and N64. It’s a neat little setup, and packs two consoles into the space of the tiny Gamecube.

Solving A Rubick’s Cube With LEGO And Popsicle Sticks

We’ve seen automated Rubick’s Cube solvers before, but never one that has garnered as many awards as [James]’ popsicle stick and LEGO Rubick’s Cube solver.\

To keep the project complexity down, [James] opted not to use a webcam to detect the color pattern on each face of the cube. Instead, he wrote a little Python app to manually enter the pattern on each face before letting his algorithm loose on the cube and calculating how to solve it.

So far, [James] has seen a huge amount of success from his project. He entered it in the New Zealand Brightsparks competition netting him $1000. This competition led to a win in the Realize the Dream science competition where he won a major prize and an entry into the International Taiwan Science Fair held early next year. An awesome accomplishment from a budding hacker, and we can’t wait to see what he comes up with next.

You can check out a video of [James]’ cube solver after the break.

Deck The Cubes

deck-the-cubes

[MrBuildIt] has lived up to his name when it comes to this year’s Christmas decorations. He built a rig that spreads Christmas cheer from one end of the cubicles to the other.

In the demo video after the break you’ll see that the system is controlled by a nicely polished Android app. It lets you choose from three different Christmas songs (or no music at all) as Santa Claus makes his rounds. The app includes buttons for switching all of the lights on or off but we think it’s more corny fun to see then turn on as Santa flies overhead.

The sleigh and three tiny reindeer are suspended from a pulley system. When they make it to one end of the office a hall effect sensor serves as a limiting switch. From the look of it you’d think Santa will be flying backwards on the return trip but there is a servo that flips the thing around so that he’s going the right way.

This is quite a gaunlet to have thrown down when it comes to office decor. We’d like to see what geeky thing’s you’ve been doing with your own decorations. Get some details up on the web and send a link our way!

8x8x8 LED Cube And The Board That Drives It

November 22, 2012 by 14 Comments

Check out the LED cube which [Thomas], [Max], and [Felix] put together. But don’t forget to look at that beautiful PCB which drives it… nice! But hardware is only part of what goes into a project like this one. After the soldering iron had cooled they kept going and wrote their own software to generate patterns for the three-dimensional display.

Looking at a clean build like this one doesn’t drive home the amount of connections one has to make to get everything running. To appreciate it you should take a look at this other 512 LED cube which has its wires showing. You can see from the schematic (available in the project repository) that all of these lines are managed by a series of shift registers. The board itself connects to a computer from which it gets the visualization commands. A Java program they call CubeControl can push letters or turn the cube into a VU meter.

The team built at least two of these. This smaller version uses red LEDs, while the larger one shown in the video after the break has blue ones.

4096 LEDs Means The Biggest LED Cube Ever

October 21, 2012 by 60 Comments

Adaptive Computing, a cloud management and high performance computing outfit in Utah, needed something really cool to bring to their trade shows. Something that makes order out of chaos, and demonstrates their attention to detail in the midst of miles of wiring. They decided building the largest non-commercial LED cube would be a good project, and thus the 16x16x16 All Spark Cube was born.

The All Spark Cube was constructed using 10 mm RGB LEDs wired together with three-foot lengths of 16 ga pre-tinned copper wire. In this video, [Kevin] shows off the process of constructing a single row; first the LEDs are placed in a jig, the leads are bent down, and a bus wire is soldered to 16 individual anodes per row.

The hardware for the build uses 16 Arduino Megas with a custom-made shield powering a 16×16 LED grid. The custom shields provide the 24V for the LEDs, 5V for the ‘duino, The Arduino boards communicate to each other through an RS485 connection, and the entire cube is connected to a computer through an RS232 serial connection.

The software is, admittedly, still a little janky. [Spencer] and [Thomas], the Adaptive Computing volunteers that are working on the control system, are still having a few problems getting logos and animations to display. They have managed to create a control app to draw individual pixels, as seen after the break.

Not bad for nearly a mile of wire and a summer’s worth of work, huh?

Hackaday’s Portal Gun Actually Levitates A Companion Cube

October 11, 2012 by 57 Comments

I was out to lunch with a couple friends, brainstorming ideas for fun projects when one of them says “Wouldn’t it be cool if we could build a working gravity gun?”. We all immediately concurred that while it would in fact be cool, it is also a silly proposition. However, only a few seconds later, I realized we could do a display piece that emulated this concept very easily. Floating magnetic globes have been around for quite some time.

I determined I would tear the guts out of a stock floating globe and mount it on a portal gun, since they’re easier to find than a gravity gun. I would also build a custom companion cube to be the correct size and weight necessary.

Rubik’s Cube For The Blind

September 27, 2012 by 18 Comments

Check out this Rubik’s Cube for the blind. The idea didn’t start off as an accessibility hack, but instead as a way for [Brian Doom] to figure out where the face of each cube goes when manipulating the puzzle. It gave him tactile feedback and his ability to use it in dim lighting was when it dawned on him that this could be useful to others.

Now when we first thought of a puzzle for the blind the term ‘Braille’ immediately jumped to mind. But this doesn’t use it. That’s great, because not all visually impaired people can understand Braille. Instead, this uses dimension and texture to identify each of the puzzle faces. There are mushroom-shaped knobs, Phillips screws, adhesive rubber bumpers, raised text label maker labels, and a few other items that go along with each color. This doesn’t prevent those with sight from playing either. It’s something of one Rubik’s cube for all. Well, all except for the robots made to solve a stock cube.
