Questions
How big is the Random Jazz Generator PCB?
It measures 167.8 × 200.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Random Jazz Generator use?
132 parts, built around the TL082, 74HCT157D, 74HCT4520D and 74HCT04D. 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 Random Jazz Generator KiCad files?
From the telec16/modular-synth repository on GitHub, at the commit this page was made from: the board is RJG/Random Jazz Generator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Random Jazz Generator design in my own project?
Its repository states no licence, so its author keeps all rights: ask telec16 before reusing the design.
