This is a two channel version of BMC006 Voltage To Rhythm. It was designed to be a more beginner friendly build, though it requires an external clock. It takes a DC voltage and converts it into an 8-beat length rhythm.
This module can be used with +/-12V or +/-15V systems by changing a single resistor value, as explained in the documentation. It does require a custom programmed microcontroller, which is provided with the circuit board.
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 and PICs are available now. Price for 1 PCB/PIC set is is $14.
Unfinished eurorack
panels are available for this project, they are 6HP 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.
