Main components
2README
README.md
bzzzbz is a video synthesizer that dynamically reacts to an audio input to create images and visuals that can be manipulated for integrated audio-visual performances.
This product is meant to be a simpler and cheaper alternative to commercial analog video synthesizers, still providing a flexible interface to enhance musical expression.
If you are a musician, a visual artist or are curious about the mesmerizing videos on the wall of your local techno club, build and use bzzzbz to experiment and play with audio-reactive visuals! Among its main features, this open-source video synth gives you the live control of video parameters and the possibility of creating your own mappings and patterns for immersive audiovisual performances.

Questions
How big is the Bz hat PCB?
It measures 140 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bz hat use?
63 parts, built around the MCP3004-I/P and NHD-2.23-12832UCB3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bz hat KiCad files?
From the dvr0/bzzzbz repository on GitHub, at the commit this page was made from: the board is hardware/v2.0/bz-hat/bz-hat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bz hat design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
