[Ron Alsing] wanted to try out some genetic programming, so he created a simple test problem: Could you render the Mona Lisa using just 50 semitransparent polygons? The program starts with a random DNA sequence. It then mutates and compares itself to the original image. If the mutation is closer, it becomes the new sequence. The final image he … Read the rest
[kap4001] built what has to be the simplest laser scanner possible. It’s two servos strapped together with zip ties plus a 5V laser module. They’re connected to a Pololu serial servo controller. The laser is pulsed by switching the DTR line. You could use it to draw images like the one above… except that’s an 85 second exposure… Read the rest

No more need to worry about security patches taking away … Read the rest
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 … Read the rest
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 … Read the rest
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 … Read the rest
