In this post I will document an OCXO upgrade board I designed for the Fluke/Philips PM66xx line of frequency counters. Introduction A few months ago I purchased a Philips PM6674 frequency counter on eBay. It’s an older 9 digit counter with two channels that has a maximum input frequency of 550MHz. The design feels dated

Ever wondered if your phone can play games by itself. Yes, it is possible. You can build a circuit to play Piano tiles on your smartphone. The video shows the demonstration of the project. Step 1: Components Required And the circuit can be built with simple components like Light sensors, Relays and Arduino. Three main

Hello friends, hope you all are having fun in your life. Today’s tutorial is about the component designing in Proteus ISIS. This tutorial actually deals with the presentation of your project. Usually when students give presentation of their projects, then it is asked that add the circuit diagram of their project. Now when students open

In this project, we will learn how to control the brightness and colour of an RGB LED via I/O ports with PWM output capability, and a touch display sliders. The 4Duino resistive touch display is used as a means for a graphical interface to control the intensity and colour of the RGB LED. RGB LEDs

In the name of science, I introduced three of the worst 12V adapters (from My kingdom for a 12V adapter) to my bandsaw. What I found may shock you. Note: All pictures can be zoomed or opened at full size in their own tab. First on the chopping block, the “EH1205”. Wait! What’s this? The

DETAILED DESCRIPTION This project is a simple linear bench power supply with adjustable voltage and current. It is meant to be a learning experience, putting ideas of circuit design, feedback, stability into practice building a complete practical power supply. I have intentionally avoided using a 3 terminal regulator or purpose built chip and instead implemented

In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi. In this RGB Flasher LED, we

Batteries are generally used to power up the Electronic Circuit and Projects, as they are easily available and can be connected easily. But they drained off quickly and then we need new batteries, also these batteries cannot provide high current to drive a powerful motor. So to solve these problems, today we are designing our

In this project we make a Cool Speedometer for bikes or any automotives by using Arduino which broadcast the speed using Bluetooth to an Android application that we created using Processing. The complete project is powered by an 18650 Lithium cell and hence highly portable along with your vehicle. To spice it up a bit more I have added
