It can't get easier than this: SpectraBeat's projector has been designed so all materials required can be found in your home or local shop and no technical experience is required for successful assembly.
SpectraBeat's software and instructions are free to download from www.spectrabeat.com.
For around 5 euro/dollars you will have a working laser projector in your hand in a few hours!
All you need are: stereo headphones, one laser pointer, one pocket mirror, one music player (mp3), soft earplugs and some glue. With the free SpectraBeat software and a SBPS laser projector, you can project at a large distance paragraphs of scrolling text, animations and drawings - a full visual explosion of content (with a unique soundtrack to boot...)
SpectraBeat works by transforming drawings into sound files (popular .wav/.mp3 audio).The generated sound files, when played through headphone speakers (which have been adapted to deflect a laser beam), will project these drawings onto a distant wall. A MP3 player or computer is required to play the sound file.
The aim of SpectraBeat is to provide an alternative publishing platform that is accessible to everyone and can transmit messages effectively (i.e. cheap, easy, high visibility, with hours of content, text plus animations, and forward compatible).
