Use this circuit with your circuits to output a staircase-style CV.  The 4516 Binary UP/DOWN Counter is controlled by a two 4093 CMOS NAND Gate oscillators; one controls the clock …

A simple 2 Transformer, 4 Germanium Diode Ring Modulator with a true bypass switching scheme.  Includes input for Carrier Wave modulation.  Power is only required for the status LED.

A simple switching circuit that allows you to route a signal to two different paths.  LEDs help indicate which signal path is active, although this circuit can also be used …

Originally made by Coron, the DS-8 Drum Synth circuit is a fairly complex circuit that generates some awesome analog synth tones.

Ripped straight from the Princeton PT 2399 Digital Delay Datasheet, this schematic is a great basic circuit to get acquainted with this extremely impressive Integrated Circuit.

From the Princeton PT2399 datasheet.  A great starting point for experimenting with the PT2399.

A highly modified Linear Feedback Shift Register circuit with a lot of oscillators.  Sounds a lot closer to vintage Atari than the much-more-famous Atari Punk Console.

A simple circuit that allows for power to be switched between a 9V battery and an AC-DC Adapter.  This snippet is useful for the beginning of power supply design for …
