Cheap 40kHz Clock - ASCII format. This circuit has worked
for me in many applications. (it might be an idea to buffer the signal befor
using it. (There are still 5 unused gates in the 'C14) (electronic circuit
added 7/03) |

CMOS Schmitt Trigger IC Makes VCO - By changing the supply voltage
fed to a classic 4584 Schmitt trigger type oscillator, the oscillator
frequency can be changed over a range of 50:1. A 74HCU04 inverter is
used at the output of the 4584 to maintain a constant TTL logic level
signal.... [Designed by David A. Johnson] |

Miniature Audio Oscillator - The Miniosc, low distortion battery
powered audio oscillator .... |

Minimal audio oscillators - In order to generate a single note you
may try these simple circuits. With only three components you may implement
some basic buzzers. You need a telephone earpiece for the first
circuit.....(added 9/07) |
