This module is a 6-bit digital to analog converter with parallel inputs. Each of the six inputs corresponds to a bit in a binary number with the top input being the most-significant bit and the bottom input being the least-significant bit. The output is an analog voltage that corresponds to the binary number formed by the inputs.

This means that each input raises output voltage by twice as much as the previous input did. In my testing I've calibrated it so that the least-significant bit was 1/12 th of a volt (0.0834V) so that when the output is fed into a 1V/oct input on an oscillator it was a musical semi-tone, the next input a full- tone and the next two full tones, etc.

Demos, build documentation, drill guide, are available here.

Unfinished panels are drilled by hand in my garage, they are bare aluminum that may be scratched.  They are intended to be painted, etched or otherwise finished later.

Pre-Assembled Modules are built after the order comes in.  Build time can be a few days or a few weeks depending on what parts I have on hand.  When ordering, please leave a comment at checkout if you have preferences on what color(s) the panel is painted.
