BMC82. Triangle Frequency Doubler

picture of the module

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.

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.
