This is simple circuit that illustrates the function of the programmable unijunction transistor. It may be quickly wired on a proto-board. The programmable unijunction transistor remains dormant until ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...

Regardless of whether you want to effectively imitate a house fire, a campfire, or light from welding, the circuit described here fills the bill without using a microcontroller, although it does use a ...

This file type includes high-resolution graphics and schematics when applicable. 1. This voltage-to-frequency converter uses a unijunction transistor to send a pulse back to the ampâ s positive input.
