This is an interesting twist on multi touch input. [s9lucas] is using a simple multitouch system as an instrument that uses solenoids and pinballs to make music. He has taken the basic multitouch tutorial and combined it with an Arduino bell tower. The end result is possibly more fun to watch than it is to listen to, but that’s fine.
[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.
[Ben Heck] posted an interesting one-off project he built many months ago. Video game developer Infinity Ward approached him to build a large display that indicated what buttons on a controller were being pressed. They were planning on using it during player testing by recording the board and the monitor at the same time. They could then compare the two to see if there was any disconnect between the players input and the onscreen action. Infinity Ward is the developer behind games like Call of Duty 4.
[Ben] piggy-backed the switch connections and added an external port. He used a pair of octal buffer ICs to replicate the signals and activate the LEDs. The whole board is powered by the same 3.3V line that’s used by accessories like the chat pad. The triggers have three LEDs each and are lit using a resistor ladder. [Ben] comments that since this is a newer Xbox 360 controller, the active-low button scheme makes it fairly easy to work with. There is a video of the board embedded below.

[Guy John] sent in this cool sequencer project. He’s using the game Go as the input. A web camera pics up the location of the pieces on the grid and plots them in his sequencing software. You can see that it is still very much in progress, but it is coming along nicely. He openly admits that it may never be completely practical. There is still so much to be improved to get it even comfortably usable, such as motion detection to remove his hand from the mix when re locating the Go pieces. This project is very similar to the Skittles interface that we posted back in July. It would be kind of interesting, though probably repetitive, to actually play a game of go and listen to the variations in the music while you play.

The Evolution Control Committee has been doing live mashup performances for many years and recently upgraded their hardware. Inspired by [Johnny Lee]’s Wiimote whiteboard, they built a rear projection display they could use during performances. It displays a dense collection of samples in Ableton Live. On each of the performer’s hands is an IR LED mounted to a thimble. By touching the thumb to the forefinger, the LED turns on. Two Wiimotes watch for these IR flashes to trigger mouse clicks. [TradeMark G] found the Ableton display too complex to navigate quickly and accurately with a mouse; this new display make things much easier and enjoyable.

Christmas is coming up pretty quickly. [tinkernut] shows us how to do a quick and dirty music activated Christmas light setup. Simply crack open a pair of old computer speakers and wire the speaker leads to a relay. Use that to power an outlet and you have music controlled lights. The section at the beginning of the video is a bit misleading as that kind of choreography would be rather difficult with this setup. This may look familiar as we mentioned an almost identical project back in 2006.

Embedded above is a review/demo of [Ben Heck]’s Access Controller. The controller is designed for one handed use and has reconfigurable/hackable modules. The reviewer is [BawNeY] a one-handed Major League Gamer. When using a standard controller, he cradles it on his lap, steering with one hand, and hitting the trigger with his elbow. The new controller looks a lot easier to use.
