[Olivier] told us about this fantastic project where he built his own RC airplane. The airplane itself is nothing special, it is the controls that are worth paying attention to. He used an Arduino Diecemilla , some XBee transceivers, and a SparkFun Wee. The main site is a general overview, but there are links to more detailed breakdowns of how to build some of the parts. There are several videos of him flying it as well.
Arduino has just released an official ethernet shield. It’s based on the same WizNet W5100 chip that was used in the tiny ethernet board we covered earlier. The W5100 handles the full IP stack and can do TCP or UDP with four simultaneous sockets. The board has a power indicator plus six LEDs to debug the connection. It works with the standard ethernet library. The reset button resets the shield and the Arduino. The SD adapter is not currently supported by the Arduino software.
[Eric] sent in this cool project that he did as part of his graduation project. He built a game that uses a gyroscope as an input device. For the gyroscope, he’s using a Powerball with a sensor inserted into it. This data is gathered by an Arduino in a pretty enclosure. The whole unit connects to a PC via USB and is supposedly plug and play. There’s a video of the setup in action on the site, just try not to laugh too hard watching them.

got an old cdrom and an Arduino laying around? Why not make it into a spinning POV display. It was built using parts from a floppy drive and a cdrom, as well as an Arduino and a small wireless transceiver. Using an IR sensor to detect rotations, the Arduino sends data to the LEDs. The wireless is used when sending new messages to the device. The link is in Spanish, so here’s the Google Translation.

ZigBee is a low-power communication system using digital radios. It’s intended to be easier to work with than Bluetooth. Adafruit recently added an adapter board for Digi’s XBee product line and has put together a great how-to to show the devices potential. Using two XBee radios and adapters you can wirelessly program an Arduino board. This would be great if your Arduino was installed in an inaccessible area or maybe it’s over 100feet away from where you’re working. The radios do serial communication just fine. What the how-to covers is getting the reset line working so the Arduino can restart automatically after you program it. Once the radio pair is configured properly, it will pass the RTS line state directly from one device to the other.

For roughly $250, you too can have this sweet bit of gadgetry based off of the Arduino platform. It is open source, and has some pretty impressive specs. Sporting a rumble pack, lithium ion battery, OLED display, and space for expanson. You can buy the pieces pre assembled, or as a kit. If you get the kit, you’ll see that the controller board has been laid out so that you can solder your buttons and joystick in as either left handed or right handed. The only problem? No games yet.
With the release of the Arduino Duemilanove, Adafruit is trying to shift out some old stock Arduino Diecimila by offering 10% off. [amk] noted that the new Duemilanove is not so much an upgrade as an Arduino with a new hat. The only changes were autoselecting power and a cutable reset line. The best part about the Adafruit sale is they’re offering Atmega328s preloaded with the Arduino bootloader as a $5 upgrade. The Atmega328 gives you twice the flash memory, twice the RAM, and twice the EEPROM than the original Atmega168.
