IC 4026 is comprised of a 5-stage Johnson decade counter and an output decoder that transforms the Johnson code into a 7-segment decoded output to drive a single 7 segment numerical display. These devices offer significant advantages in display applications that prioritize low power dissipation and/or low package count. Both sides of IC 4026 have […]

Morse Code Practice Oscillator Circuits
In this article we will explore 3 different Morse code practice oscillator circuits, for generating exact replication of Morse code signals in the form of dots and dashes. Contributed By: Anil Patil What is Morse Code Morse code is a legacy method of message encoding that uses rhythm and impulses to transmit telegraphic communication. Morse […]
12 Simple IC 4093 Circuits and Projects Explained
The 4093 is a 14-pin package containing four positive-logic, 2-input NAND Schmitt trigger gates as shown in the following figure. It is possible to operate the four NAND gates separately or collectively. The individual logic gates of the IC 4093 works in the following manner. As you can see each gate has two inputs (A […]
Ion Detector Circuit [Static Discharge Detector]
The following post discusses a simple ion detector circuit which can be used for detecting positive and negative ions generated by high voltage circuits. This device can be also used for detecting static discharges in the atmosphere. Static discharge is normally emitted by high voltage sources such as sparks, arcing etc. It may be also […]
