Controlling a robot simply by looking at your desired location is pretty freaking awesome. A web camera pointed at your face, analyzes your movements and pupil direction to send the bot signals. Look at a location and the bot goes, change your expression to send other commands to the bot. This easily surpasses the laser guided assistance droid for ease of use.

The Nintendo keyless entry system will vigilantly guard your door from intruders. Enter the right code and you get access, enter the wrong code and it will deny you and take your picture. [action_owl] did a fantastic job on this lock, using mainly recycled parts like an old CDRom and an Arduino. It works both with or without the computer. If you choose not to use the computer, you don’t get pictures of the people who entered the code wrong.
We like this project, but we feel it needs to be pointed out that this lock is pretty useless. Everyone already knows the code to get in is UP, UP, DOWN, DOWN, LEFT, RIGHT, LEFT, RIGHT, B, A.
If you can get through the cell phone text speak, you’ll probably enjoy this cool tutorial on how to build a cell phone controlled robot. This bot decodes the key tones, similar to the automated phone systems we’ve all experienced. It uses a chip called a MT8870 DTMF decoder to translate the signal for the Atmega 16 controller. The circuit diagram is pretty hard to read, maybe we missed a downloadable one somewhere. The source code is available.
It would be nice to get some feedback from the robot, so you aren’t driving it completely blind. This is similar to the Lego cell phone rover that we showed you before. Next, he should make it recognize voice commands.
The 25C3 team has a post highlighting some of the hardware workshops that will be happening at Chaos Communication Congress this year. Our own [Jimmie Rodgers] will be in the microcontroller workshop area building kits with many others. The folks from mignon will be bringing several of their game kits for another workshop. We saw quite a few quadcopters at CCCamp and the team from Mikrokopter will be back to help you construct your own drone. They say it only takes five hours for the full build, but space is limited.

You’ve probably seen musical Tesla coils already. People have wired them up to computers and keyboards to make them serve as dangerous and awesome speakers. This video popped up of someone playing his guitar through one. It is rough, and not very good at polyphony, but still cool. We would like to see several coils, split by different filters to be able to hear more of the guitar chords. If only someone had rigged these up for Queen when Flash Gordan was made.
Finding themselves in need of a thermometer that could communicate with the computer, The Cheap Vegetable Gardener resorted to a bit of hacking. They created this PS2 controller thermometer by attaching some thermistors to the analog stick inputs. Each PS2 controller could collect data from up to four thermistors. There is an auto shutoff feature built into the controller that shuts off the analog signal after a period of non use. To overcome this, they simply taped the L2 button down.

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.
