A Patch Session

I have got to get more patching cords!  Very easy to run short in session.  Been busy doing a number of different projects but I have finally fixed a few trouble spots on my lunetta.  The added 4040 in this example gives me more octaves to play with.  The added 4046 pitch tracker has a pot instead of a fixed resistor on pin 9.

Lunetta Lessons: 4015 Demo


Here's a little demo of the 4015 shift register now with twice the flavor.  Two oscillators control the Data and Clock pins of one half of this dual shift register chip.  I take its four outputs and connect them to my R/2R ladder and then feed the output to a 4046 vco.  None of these "modules" are difficult to build and the results are fun.
