Virtual Windows That Track A Viewer’s Position

April 16, 2010 by Mike Szczys 44 Comments

Winscape will let you replace that garbage-strewn ally view with just about anything you want. The two windows above are actually plasma screen televisions. In between them you can spot a Nintendo Wii Remote that is used to track an IR badge worn by the person in the room. As they move, the images on the screens are changes to simulate the change in perspective you would see out of a real-world window. Take a look at the video after the break. This is unfortunately not an open source project but the software is available for trial and we find the concept interesting. If you can write video processing algorithms you may be able to take the Wii Remote Whiteboard concept and turn it into a Winscape clone.

Arduino IPod Library Work Continues

April 1, 2010 by Mike Szczys 24 Comments

[David Findlay] has been hard at work on his Arduino iPod remote library and is now showing off some Wii Nunchuck control in the video after the break. When we looked in on his work in September he was using a Staples Easy Button to control the iPod. Now he’s added all of the functionality for iPod simple remote mode, and most of the advanced mode.

Advanced mode works well with his iPod Photo but the iPhone just returns errors. We know that Apple uses some tricks to keep unauthorized accessories out, so we hope that [David] finds a way to sniff out the necessary accessory protocols from an approved model.

Altoids Upstaged By Gift Card Tins

February 7, 2010 by Phil Burgess 27 Comments

Nothing Earth-shattering here. Just, dare we say it, really cute!

The venerable Altoids mint tin has become an icon of the maker culture. Browsing through past articles on Hack a Day, Adafruit or Instructables, you’ll find project after project for which these pocket-sized enclosures provided just the right fit. Eminently practical, affordable, but the aesthetics have occasionally left something to be desired.

We recently stumbled upon these nifty gift card holders that resemble miniature versions of current-generation game consoles. They might be the perfect housing for your next microcontroller project…

Game Controllers Using USB Host Shield

February 1, 2010 by Mike Szczys 21 Comments

[I-Bot] has put together some libraries that make it easy to use gaming controllers with an Arduino. They interface through the USB host shield. This means that PS3 controllers connect via USB through a cable or a dongle. With the Wii remote things get a little more interesting. A Bluetooth dongle is used to make the connection wirelessly. What we have here is a cheap and easy way to add Bluetooth connectivity to your projects either through the USB Host shield, or by building your own hardware with the schematics and code that are available from Circuits@Home. There are several pages that walk you through the protocols using as well as a demonstration video you can see after the break. Continue reading “Game Controllers Using USB Host Shield” →

Wii Motion Plus Direct PC Interface

February 1, 2010 by Mike Szczys 7 Comments

You can pick up a Wii Motion Plus module for under $20 and that’s not bad for an I2C gyroscope. This hack taps into the device through a PC parallel port. The connection calls for some level conversion to step down to the 3.3v needed by the module. The communication protocol borrows from the Wii on Arduino code examples that we saw last year. You can see the Wii Motion Plus controlling a virtual cube in the video after the break.

Wii Nunchuk Train Controls

January 18, 2010 by Jakob Griffith 11 Comments

While we’ve been told all of our lives Wiis and trains just don’t mix, they never said anything about Wii Nunchuks. One terribly abused joke later, [Ken] tipped us off about his Wii Nunchuk controlled train set.

By utilizing Digital Command Control (think pulse-width modulation) with an Arduino, he is able to have full control over the trains direction and speed. The other part of the equation is a Wii Nunchuk and adapter. The setup should be pretty self explanatory, but there is an Instructable for those that need more help.

Max/MSP Accelerometer Beat Control

[Ryan] let us know about his Max/MSP Controller. Inside the device is an ADXL 335 accelerometer and 6 push buttons wired to an Arduino. The input data is sent to Max MSP, a sequencer controlling 5 audio tracks, correlating to 5 of the buttons. The 6th button controls delay. What we really liked was how the accelerometer modified the speed of the beat in the X-axis, and the delay intensity with the Y-axis. Whats next? We think gesture recognition might be something fun to try, but [Ryan] is unsure. We’ll keep you up to date.
