Wireless Bootloading

Tired of having to physically connect to your microprocessor to upload new code? Just do it over a wireless connection. [Nathan] takes us through the process of setting up a wireless bootloader for the ATmega168. He is using the XBee base and remote modules for the wireless communication. While people have been doing wireless bootloading with the Arduino already, [Nathan] found that it was common for them to have timeout issues. His remedy was to make his own custom one that is much faster. He’s asking for help though. At this point it is tested and working, but he needs someone with more programming knowledge to help him make it “drop-in” compatible with the Arduino IDE.

WiFi Theremin

January 23, 2009 by Eliot 9 Comments

The fine folks at Midnight Research Labs have put together a new toy for you to play with. It’s a Python script that makes your WiFi hardware behave more like a theremin. Based on the pyaudio library it monitors the signal strength of the AP you’re connected to and changes the tone accordingly. There’s a sample embedded above (direct link). If you have a second interface, you can use it to modulate the volume. It’s an interesting trick, but they say that there’s enough latency that it would be hard to play actual music with it.

Chumby Digital Picture Frame Teardown

January 20, 2009 by Eliot 27 Comments

At this year’s Consumer Electronics Show, Chumby unveiled their latest prototype. It’s a network connected digital picture frame that runs Flash widgets. Just like the current Chumby model, they’re publishing the software and hardware under a license designed to let you hack it. They let us borrow one of their open chassis evaluation kits to teardown and photograph. We’ve got more pictures, full specs, and the schematics below.

Bug Labs Introduces New BUGmodules

Bug Labs, the company that makes modular electronics that allow you to build your own tech doohickeys quickly and easily, has announced five new modules: BUGprojector, a mini DLP projector developed in conjunction with Texas Instruments, which sounds very much like the tiny DLP projector we posted about last week; BUGsound, an audio processing module with four stereo input/output jacks, a microphone, a speaker, and builtin hardware codecs; BUGbee (802.15.4) and BUGwifi (802.11 and Bluetooth 2.0+EDR), which will let you connect wirelessly with your PAN and WLAN, respectively; and BUG3g GSM, for connecting to (you guessed it) 3G GSM networks. In conjunction with Bug Labs’ existing series of modules, especially the highly versatile BUGvonHippel universal module, you’ll be able to create some pretty kickass gadgets. No word yet on pricing, although Bug Labs expects to ship by the end of Q1 2009.

WiFi Streaming Radio

[Jeff] is continuing to work on his WiFi streaming radio project and is now into part 7. The reason it’s taken so long is because he’s bothering to document every single piece of the system instead of assuming too much of the reader. The core of the system is an Asus WL-520GU wireless router. It is supported by OpenWRT and has a USB port for use with an external audio card. mpd, Music Player Daemon, is used for playback. This latest part features adding an LCD display for the current track. The router board already has points for the serial port, so it’s just a matter of adding an AVR to talk to the LCD. The next step is building a simple user interface and then boxing everything up. You can view a video of the display below.

Nintendo DS OSC Support

dsmi

OpenSound Control protocol is an emerging standard for communication between musical programs. It’s meant to replace MIDI. The DSMI, DS Music Interface, team has just added support for OSC. You can now use your DS as generic OSC music controller over WiFi. OSC has TCP/IP support built in, so there is no need to run a host sever to talk to DSMI like you did when they only supported MIDI. We’ve seen OSC used in other projects like the monome. It’s also the basis for the multitouch communication protocol TUIO.

Xbox 360 Portable

A couple months ago we posted [Ben Heck]’s in-progress photos of his Xbox 360 laptop (with links to his other versions). He’s just put the finishing touches on it, and dubbed it the Xbox 360 Portable. It has a removable hard drive on top and memory slots on the side. The webcam is embedded in the frame and there’s internal WiFi. With chatpads available now, he’s decided not to include a keyboard. It’s really a nice machine. Check out the video below for a tour of the system.
