[Andrius] just sent in his robot Rubik’s cube solver. It isn’t as fast as the solver we saw last year but it also doesn’t require as many parts either. This project utilizes two claws, each actuated by just two servo motors. The thinking is done by a PC which calculates the necessary moves to solve the cube. Each instruction is then passed via USB to the AVR ATmega16 microcontroller that is responsible for the servo operation.

Right now it looks like the colors for each starting face have to be entered manually before a solution is calculated. We think [Andrius] is probably planning to upgrade this with the next generation of his software as he already has a webcam setup for this type of analysis.

In light of our recent rash of Nintendos stuffed into other Nintendos, we are happy to show a Nintendo mod project that breaks form and makes something marginally useful. [Sami] added an LCD to his GameCube, and made it look good too. Attached to the top of the GameCube, it hinges at the side allowing for you to close it all up for transport or storage. Great job [Sami].

Gamecube Controller For The Wii

[marcan42] wanted to use a plain old GambeCube controller to play Super Smash Brothers Brawl and some other titles. Apparently you can just use a WaveBird wireless controller but according to [marcan42] they are hard to find. You may recall a similar project for building a wireless Snes controller for your Wii.

CuBear, Berkeley’s Rubik’s Cube Solver

A team of five UC Berkeley engineering built this impressive Rubik’s Cube solver. The CuBear is a giant transparent cube with a servo attached to each face to rotate the cube’s six faces. The user can either scramble the cube using computer controls or show the faces of a scrambled cube to the onboard webcam, and the machine will replicate it. While scrambling the cube may take many moves, the computer calculates the shortest number of moves to solve the cube before proceeding. Team member [Dan Dzoan] is quite a fast solver himself, as you can see at the end of BotJunkie’s video embedded below. Continue reading “CuBear, Berkeley’s Rubik’s Cube Solver” →

3x3x3 LED Cube

June 20, 2008 by Eliot 9 Comments

[portreathbeach] built this simple 3x3x3 LED matrix. It uses a PIC16F690 in a ZIF socket for the brains. Each layer has nine LEDs with the cathodes tied together. The anodes from each LED are connected to the LED below. The LEDs are multiplexed so that even though all layers appear to be on, they’re being addressed individually. He’s included software, so you can build your own animations. Video of the matrix in motion is after the break.

AudioCubes By Percussa

May 23, 2008 by Sean Percival 10 Comments

[Peter Nyboer] has written an extensive post about his experience with AudioCubes from Percussa. Aside from their unique glowing exterior, these cubes are an innovative way to control and even produce audio tracks. Four faces of each cube are equipped with IR sensors to detect distance and communicate with other cubes. The cubes also have USB, a rechargeable battery, and audio in/out. Moving your hands around the sensors changes the MIDI output of the cube. Changing the cubes’ orientation and distance from each other also changes the signal. Max/MSP and Live are both supported out of the box, but that doesn’t mean it’ll be easy to get started. [Peter] makes an important point: unlike traditional instruments, there’s no obvious way to get started. At 400euro for 2 cubes and 650euro for 4 cubes, these devices aren’t exactly being given away, but it’s great to see new interfaces being imagined. A video of [Peter]’s first experiments with the cubes is embedded below; read his full post to see more footage of the cubes in action… and naturally we’d love to see any DIY versions of this you can come up with.

DIY Wireless NES Controllers For Wii/Gamecube

February 20, 2007 by Will O'Brien 11 Comments

[Mark] sent in his wireless classic nintendo controller project. He built a wireless NES and SNES controller to use with his Wii via the Gamecube port. He used off the shelf TX/RX hardware and used some PIC controllers to glue everything together. iPod batteries keep em powered and keep the weight down. He provides all the schematics and a walk through on constructing the SNES controller. The circuits are pretty simple, so it’s definitely repeatable. This is almost enough to get me to buy a Wii.
