We all know that it’s easy to get caught out by fake electronic components these days, with everything from microcontrollers to specialized ASICs being fair game. More recently, retro components that ...

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 ...

Download the PDF of this issue that presents a ramp transistor leveraging MCU emulation of a unijunction transistor and how to achieve full-spectrum light with an LED microscope illuminator's current ...

This simple Mock Flasher LED simulates the indicator of a sophisticated Alarm system. It can be placed in doors, gates and vehicles to confuse intruders. The circuit is too simple using a Unijunction ...
