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.

Netbook Comparator

netbooks

Our recent netbook post got a huge response. They are almost unanimously loved. A few dissenting opinions were present though. A few people mentioned that until this generation arrived, they were buying used subnotebooks for exactly the same reasons.

If you’re in the market for a new machine, Obsessable’s netbook comparator has all of the current models broken down by feature.

Arduino Shield Scaffold

[Garrett] from macetech has been prototyping shields for the Arduino development platform. Arduino’s have an inexplicable nonstandard spacing between two of the banks of output pins. This means that you can’t use regular perfboard with them. To make the design process quicker, [Garrett] has put together an Eagle file that just includes the male header pins. The file also has a line indicating the tall lower board components so you can avoid creating shorts.

Track The Sun For Home Lighting.

Have a room in your house that really could benefit from some sunlight? Build a Suntrack to reflect light in as long as possible. The two axis motor set up is built from a couple of satellite dish positioning motors with the control electronics removed. The whole thing is controlled with a PIC 18f2520. Once calibrated, it will reflect the sun into your room, updating every twenty seconds. While this may not be the most efficient way of lighting a room, it is a cool way to do it if you absolutely must have sunlight. We can’t help but wonder if there would be a way of using a solar powered system to do this to save energy. Could this possibly be done using BEAM “head” circuit?

LED Projector

[PuffMag1cDrag0n] shows us how to make a fairly simple projected LED display. The projector is made from a 13×7 LED matrix and a couple fresnel lenses. The layout and construction is similar to the Lumenlab projector setup, only replacing all the lighting and LCD with an LED array. It communicates via serial port and is powered by a pic micro 16f648. We would love to see an RGB version of this. The directions are a bit rushed, but you should be able to get the gist. Just remember that you need some pretty powerful LEDs to throw a big image.
