PCB designing is a vital step in every product development cycle. The below list provides you with a collection of DIY PCB Projects which can be used to develop PCB designing skills. Each project consists of a useful practical circuit that is demonstrated with a neatly fabricated PCB. The design details including the Gerber file is available for download to provide a complete do-it-yourself experience.
I have come up with the idea of a Coffee Alarm as a solution to my own real-life problem. Like any other youngster, I normally have a lot of tasks to complete every day. Before going to bed every night, I set my alarm at 6 A.M., and when the alarm starts ringing, I snooze it repeatedly and wake up at around 9 A.M. I tried different alarm apps which demands…
Well, IoT is trending everywhere and is one of the greatest things that can be used to make life easier. There are many IoT based home automation projects available on the internet but none of them provides you an option to control the speed of fan over the internet. So here, in this project, we’ll be making an IoT fan speed control…
If you have ever worked with Batteries, SMPS circuits or other Power supply circuits, then often it would have occurred that you have to test your power source by loading it to check how it performs under different loading conditions. A device that is commonly used to perform this type of test is called a Constant Current DC Load, which allows us to adjust the output current…
Hello! everyone, this tutorial will be extremely exciting for electronics makers because we will be designing our own touch-capacitive Piano with Arduino Nano. We will include a recording and replay feature on our Piano. So far, we've made a few piano projects using Arduino, but this one is quite different because we are going to use capacitive touch keys for our piano…
We often see voltage fluctuations in electricity supply at our home, which may cause malfunction in our home AC appliances. Today we are building a low cost High and Low Voltage Protection Circuit, which will cut off the power supply to the appliances in case of High or Low voltage. It will also show a alert message on 16x2 LCD. In this project, we have used PIC…
In this tutorial, we are going to build a handheld game console using Arduino Pro Micro, Arduboy package, and a handful of hardware. For those who don’t know, Arduboy is an 8-bit, credit-card-sized programmable gaming system inspired by Nintendo Gameboy. Arduboy is a game development system based on the popular open-source Arduino platform. It is really easy to learn, share…
The features of the digital products are growing enormously which triggers the frequent usage of smart phones in several applications. Thus the battery backup time is getting decreased. It will be fun to build a Power Bank for Mobile Phone as spare charging source for emergency purpose which is also portable.
Previously we have made…
Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million). This circuit triggers the Buzzer when Smoke level…
Knowing the whereabouts of a particular object/person has always been comforting. Today, GPS is being extensively used in asset management applications like Vehicle Tracking, Fleet Tracking, Asset monitoring, Person tracking, Pet Tracker etc. For any tracking device the primary design consideration will be about its battery expectancy and monitoring range. Considering both,…
Battery cells are the most commonly used energy source to power portable electronics. Be it a simple alarm clock or an IoT sensor node or a complex mobile phone everything is powered by batteries. In most cases these portable devices need to have a small form factor (package size) and hence it is powered by a single cell battery, like the popular CR2032 Lithium cell or the…
In the field of DC-DC Converters, A single-ended primary-inductor converter or SEPIC converter is a type of converter that uses a boost type control topology to step up or step down the input voltage. After reading this, the first question that will come to your mind would be, is it like a glorified Classic Buck-Boost Converter? The answer is yes and no. A classic buck-…
Relays are common in many switching circuits where controlling (turning ON or OFF) an AC load is required. But due to the electromechanical characteristic, a mechanical relay has a self-life, and also it can only toggle the status of the load and cannot perform other switching operations like dimming or speed control. Apart from this, an electromechanical…
