This circuit uses a Motorola component from the 90's and is suitable for the diode-transistor logic of the time. The circuit can be adapted to use more modern equivalent logic.
This project is of great use as it serves both to feed test equipment as well as to the component...
This conventional slow-moving circuit uses incandescent light bulbs, but can be changed to use...
This circuit generates sawtooth signals whose frequencies depend on the values of the selected...
