Divide & Conquer

PCB set = USD22
panel = USD20
Assembled = USD190

This is a clock divider module containing 4 different dividers:
  1. /2, /4, /8, /16, /32, /64, /128, /256
  2. /1.5, /3
  3. /2.5, /5
  4. /3.5, /7

All sections will run off a signal patched into section 1.
The module can be patch-programmed to obtain other divisions. For example; patch output /2 into section 4 to get divide by 14 from the /7 output.
The circuit is CMOS based and contains no microprocessors.

This module is intended to be a companion module for the Bindubba Sequencer.
Yes, the first run of panels has an invisible '64'.

    1. Yes, I sent some to Thonk a month ago. If not listed maybe ask directly. Otherwise shipping from me is USD5 for posting as a regular airmail letter.
