This circuit is a new type of comparator. A microcontroller checks the input voltage against a data table that tells it whether to turn it's output on or off. This is repeated 4 times for 4 different outputs. The data tables are written by the user using pushbuttons or external trigger/gate sources.
12V and 15V system compatible. PCB Mounted Pots.
For complete descriptions of the way the module is used, and how to build it, including schematics and parts list; download this PDF file.
Boards are available now. Price for 1 PCB/PIC set is $20.
Unfinished eurorack
panels are available for this project, they are 10HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
