draft6

Guitar to "MIC in" converter.

This circuit converts a typical electric guitar's Hi-Z output (6.35mm) to a electret microphone input (3.5mm) on the normal sound card that usually come with your motherboard.

Compatibility

This circuit assumes your sound card provides a DC bias voltage.

Questions

What parts does the Draft6 use?

22 parts. 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 Draft6 KiCad files?

From the Jamesits/draft6 repository on GitHub, at the commit this page was made from: the board is kicad/draft6.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Draft6 design in my own project?

Its repository states no licence, so its author keeps all rights: ask Jamesits before reusing the design.
