It uses a custom song format and supports multiple lyrics display styles, background videos, real-time audio stretching and pitch shifting, and also handles microphone echo. It is written in Python and Cython and uses OpenGL graphics on the host box, while the UI is remotely accessed through a web browser (e.g. running on a tablet). There is very little documentation at the moment, but feel free to drop me a line if you’re interested or have any questions. https://marcan.st/projects/openlase/ Fri, 21 Jan 2011 00:00:00 +0100 https://marcan.st/projects/openlase/ OpenLase is an open source library and toolkit for controlling laser scanners. It has an emphasis on real-time operation and integration with audio, and it uses the JACK Audio Connection Kit as a backend. Features include: Classic OpenGL-like API Support for ILDA format sprites SVG to ILDA converter Built-in vector font Realtime bitmap tracer (edge detection) Python bindings Video player (using the bitmap tracer) Output processor GUI with perspective correction (projecting from an angle) and level controls. https://marcan.st/projects/openlase/hardware-mark1/ Fri, 21 Jan 2011 00:00:00 +0100 https://marcan.st/projects/openlase/hardware-mark1/ OpenLase is designed to work with typical DIY laser scanners that use sound cards as DACs. This is the first laser projector that I built to go along with it. It is by no means perfect, and indeed, quite a few things could be improved. It’s relatively simple though, and it should be straightforward to duplicate. Overall view Overall view There are four main parts to the scanner: the digital-to-analog converter (DAC) (and associated control circuitry), the emitter subsystem, the scanning subsystem, and the power supply.
