WiiMote + IPhone Update

December 10, 2009 by Mike Szczys 13 Comments

Using a Wii remote as the controller for iPhone games? Brilliant! We’ve been waiting to see some creative usage of this pairing since we covered it back in August. [ZodTTD] is the person who ported MAME over to the iPhone. Now he’s added support for the Wii remote in Mame4iPhone via the BTstack project. BTstack seeks to add Bluetooth stack functionality to devices that don’t have it or where it is limited (the iPhone).

We’ve embedded video after the break of the WiiMote used to play a MAME game. [ZodTTD] is also the author of nes4iPhone, we hope that’s the next project he will add BTstack support to!

(Remote Controlled Robot) Car Vs (solar Charged) Tank

[Matthias] sent in his team’s iPhone Robot (CAR) project in response to yesterday’s iPhone controlled solar charged tank. Unlike the tank, the iPhone car is controlled via Bluetooth BTnode and BTstack, and also isn’t solar-powered. However, both projects utilize iPhones and readily available components. We particularly liked how it not only used a multi-touch input, but also the accelerometer within the iPhone. It seems some competition is stirring, lets see who wins out.

InPulse Watch Gets BlackBerry Data Via Bluetooth

[Eric] just told us about the watch he developed that displays info from a BlackBerry via Bluetooth. The watch displays updates, message alerts, incoming call information, and… tells time. Setup and control is handled with the BlackBerry keypad. The device is charged with a micro-USB connection and will last for about four days without a recharge. We’d chalk up the rather long battery life to the use of an OLED display, which will use less energy when a portion of the display is left black.

So why is it here? Well, he’s got a couple of blog posts that detail two of the final prototypes that you might find interesting. What else? Oh yeah, his original prototype used an Arduino with a Nokia 3310 LCD display. For those of you who continually call the Arduino a worthless toy, looks like it’s good enough to use when taking a product to market.

Bluetooth Cartridge For Nintendo DS

We’ve received tips from a few different people about a new Bluetooth module that connects as a game cartridge for the Nintendo DS. This is a homebrew solution and not an official Nintendo add-on. The cartridge houses an ATmega168 microcontroller which provides the interface between the DS and a Roving Networks RN-41 bluetooth module.

They’ve provided a schematic for the device but we didn’t see any board artwork or pictures of the internals so you’re on your own for board layout. The libraries needed to use the bluetooth connection with homebrew software are up for download. This should provide a nice way to use the DS with a Bluetooth GPS module, or perhaps as a discrete Bluetooth sniffer and spoofer.

External GPS For IPod And IPhone

Ever wish your iPod touch or older generation iPhone had GPS capability? Now it can by using a Bluetooth GPS module along with the roqyGPS app.

In April we saw a pretty creative way to add GPS to an iPod by using a homebrew accessory. The new app is a better solution because it utilizes the larger screen and more functional UI of the iPod touch. We’re glad to see this come along because we’d rather not upgrade to the iPhone 3G just to get GPS support. roqyGPS has a fairly long supported hardware list, which should make it relatively inexpensive to pick up a GPS module either on sale or second-hand.

We’ve got a video of the release candidate after the break. As always, we’d like to hear from anyone already using this so please leave your thoughts in the comments.

Cheap Wireless For Microcontrollers

Everybody loves microcontrollers, including the Arduino, allowing you to create whatever you imagine. That is unless you want to hack together something wireless. Originally you had to rely on the expensive XBee protocol or other wireless options, but no longer. Hobby Robotics found an extremely cheap transmitter and receiver and wrote a quick guide for wiring them up to an Arduino. Now your wireless projects can come to life, as long as you are within 500 feet and don’t mind 2400bps; minor trade offs compared to the gains of wireless freedom. Final note: You aren’t limited to Arduino, we would love to see someone modify this to work with a PIC or other microcontroller.

Tiny Bluetooth Teardown

The folks at SparkFun were startled by how small USB bluetooth adapters had become so they split one open. They noted a few interesting design features. It has a small folded trace antenna on the board edge. The metal USB housing acts as the RF shield. The bluetooth IC is an AS3620QA. Now we wonder what those tiny Buffalo drives look like inside.
