Handle With Linux

One of the coolest things you can do with linux is control a show laser.

This image is generated by a module build on ucLinux the smallest Linux distro in the world:

Here's the Bilda board at work, this is a hardware controller controlled by Linux via usb. It's extremely fast and allows for projection of all kinds of great shows.

360 degrees rotating laser projection, thanks to Linux control:

Bilda board

The Bilda board is a harware controller, which can be used together with a Linux computer to control
The task of this hardware is to generate the neccessary voltage signals to control a laser projector under computer control.
The laser projector uses these signals to set the deflection angle, color and brightness of the laser beam accordingly. Through fast variation of these signals it is possible to display graphics or beam effects. Because laser projectors are vector oriented a set of deflection and color data is also called a point. Laser projectors are usually supplied with points at a constant rate, that means the time interval between two consecutive points should always be equal.

smooth color gradient, bilda can generate 16.7 million colors

colorful beams are pretty standard, all kinds of images can be projected.

bilda Software

The bilda Software consists of the following parts

* a test application to program the microcontroller and output frames and animations
* a kernel module which interfaces to user applications and feeds bilda with USB data
* a firmware which runs on bilda's Microcontroller

Controller

The Bilda controller can be easily build from common of the shelf hardware.
