After the release of his PIC32MZ EF based 20Msps oscilloscope with an integrated 1-inch by 1-inch OLED screen for readouts, Electrical Engineer, Mark Omo has again unveiled his new design, the self-contained 60MHz 250Msps Probe Scope oscilloscope with the probe in cable form factor. The...

One application of thermal imaging which has been experiencing a surge in recent times is the application of thermal imaging in the detection of faults in circuits. While this has proven a very interesting and reliable way for evaluating Circuit boards before committing to mass...

A window detector circuit, also called window comparator circuit or dual edge limit detector circuit is used to determine whether an unknown input is between two precise reference threshold voltages. It employs two comparators to detect over-voltage or under-voltage condition. This...

  The project shown here is a microphone preamplifier that provides high quality amplification, optimized for use in computers, media and mobile applications. The pre-amplifier provides a differential input stage, making the device particularly effective when layout...

One of the most important actions in the development of any electronics device is soldering, irrespective of the method adopted, having the right tools to do it the right way is a major determinant of the speed and quality of the soldering process. Several soldering tools exist in the...

This motor driver circuit can drive a brushed DC motor with up to 250W of continuous load. The project can be controlled with the general logic IO-Ports of any microcontroller. Either an Arduino Uno or another microcontroller can be used as the control board. The project uses two...

Today we are going to build one of the most important tools in sound mixing; A audio VU (volume unit) meter based on an Arduino/AVR microcontroller. This project serves to demonstrate how the knowledge of electronics can be applied to build solutions for any part of your day to day...
