This module consists of four triangle frequency doubling circuits. The circuit board
normalizes the output of each doubling circuit to the input of the next so that it can easily be used to
multiply frequency by 4, 8 or 16.
Other waveforms can be used instead of triangles but there will be more significant
alterations of the output.
The PCB is layed out for Eurorack style systems only with PCB mounted jacks.
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 is $8.
Unfinished eurorack
panels are available for this project, they are 4HP and cost $7 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.
