Music Thing Modular Turing Machine Pulse & Volts Expander

Freshly built Music Thing Modular Turing Machine Expander module that contains both the Pulse and Volts PCBs behind one panel. Power and expansion cables included.

About the expanders from Music Thing:

Pulses

Pulses turns the sequence from the main Turing Machine into a series of repeating rhythmic semi-random clock signals, that are based on the main clock input.

Seven of the 11 outputs are just the binary steps of the sequence on the front panel of the main module. The other four are derived from those pulses - so when steps 1+2 are active, the 1+2 output pulses.

Volts

Tweak five potentiometers to set up another voltage output from the Turing Machine. This can be a different melodic sequence, related to but different from the main output.

This is a simple, low-parts count, low-current expander for the Turing Machine Random Sequencer in 4HP. It connects around the back with a 16-way ribbon cable and works with any Turing Machine (Mk2, or Mk1 with the backpack).

It acts like a variable 5-bit digital-to-analog converter, taking 5 bits from the Turing Machine GATES expansion port, running them through five potentiometers and giving one summed voltage output.
