This 50% active cycle TTL clock generates signals from 4 to 20 Hz. Its power must be supplied with 5 V and other frequencies can be generated with capacitor replacement.
This circuit is intended to reduce the 12V from a car outlet to 9V. The current is in the order of a...
This circuit was found in a William Sheets. It has 75 ohms of output impedance and can operate up to 20...
This circuit generates a signal in the tone-modulated FM range for tuning receivers. The circuit is...
