The Jake’s Custom Shop Clock and Musical Divider Module seeks to act as a stand-alone rhythmic timekeeper.  An internal square-wave LFO operates as a clock source fed directly into an 8-Bit binary divider.  Each divider output halves the previous output’s frequency.  A clock signal can be divided up to 256 times.  A Clock-in jack allows for synchronization to an external clock source.

    +5V: 0mA (max)

    -12V: 0mA (max)

Internal Clock frequency (Clock Through): 2Hz(min) to 200Hz (max)

Divider Output Voltage: 0V(min) to +12V (max)


1. Square wave generator circuit with adjustable period by a potentiometer. 

2. Standard 555 Oscillator.


1. The clock divider Version 3.1 is a musical counter. Each output represents 1 digit in a binary number counting from 0 to 511. 

3. LED indicator on each output.

4. 8 available divisions plus a CLK THRU output.

5. Musical Divider. Outputs are High on initial state.  A Mathematical version 2.1 is available from JCS.

6. Operates on the Rising Edge of the clock signal.


Power: 10-Pin shrouded IDC.  Meets Doepfer Eurorack standard.

SLOW/FAST pot: Adjustment of internal clock speed.

CLOCK OVERRIDE: Overrides the internal or bus clock when a patch cable is inserted.  Inserting a patch cable that carries no signal will inhibit the divider.


/2: Divides the clock by 2

/4: Divides the clock by 4

/8: “

/16: “

/32: “

/64: “

/128: “

/256: Divides the clock by 256.

Clock through: Clock output from the internal clock or Clock Override jack.
