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.
The ESP Controllers from Espressif are becoming a widely popular choice for IoT based designs. There are many kinds of ESP modules and development boards already available in the market, among which NodeMCU is the most popular one. Apart from that, ESP-12E, ESP01 are also popular choices. But if you want to make your design more flexible and compact, chances are that we have…
The buck-boost converter is a DC-DC converter that uses the same concept of both the buck and boost converter but in a simplified combined circuit. As the name implies, the main feature of a buck-boost converter is its capability of making the output voltage constant even though the input voltage drops below the output voltage that means this circuit can work both in…
Most of our electronics projects are powered by a Lead Acid battery, in this project let us discuss how to recharge this lead acid Battery with a help of a simple circuit that can be easily understood and built from home. This project will save yourself from investing in a battery charger and help you to extend your battery life. So let's get started!!!!

In an ideal scenario, a battery should have zero internal resistance. But batteries are not made perfect and the electrodes are not 100% conductive, which creates a small resistance within the battery called internal resistance. Practically batteries will always have some internal resistance. On paper, the value of the resistance will appear low around 0.1Ω for…
In the previous parts(Part 1, Part 2, Part 3) of this project, we investigated different aspects of our smart watch projects and learned to integrate and test each individual part. In this we are going to use what we have learned to create our own smartwatch from scratch, using a combination of hardware and software components. Throughout…
Today, our desks are full of devices that require connection to be connected with the PC via USB, or we need to work with multiple devices that have USB ports. It became a problem as Laptops lack multiple ports, and this is where a USB hub or USB Port Extender comes in handy. This comprehensive guide demonstrates how to build a professional DIY USB hub with a power supply using…
Almost every Solar based system has a Battery associated with it which has to be charged from solar energy and then the energy from the battery will be used to drive the loads. There are multiple choices available for charging a lithium battery, we have also built a simple Lithium battery charging circuit previously. But to charge a battery with a solar panel, the most…
We have been using Raspberry Pi for a long time to create many exciting projects. But, oftentimes we face an issue in selecting the best power source for our projects, and sometimes when the power goes off, our raspberry pi turns off abruptly which might corrupt the OS or in the worst-case damage the board itself. So, today we are building our own Raspberry Pi Zero HAT…
RC cars are always fun to play with, I am personally a big fan of these remote-controlled Cars and have played (still do) with them extensively. Most of these cars today provide a huge torque to handle rough terrains, but there is something that was always lagging, its Speed!!.. So, in this project, we will build a totally different type of RC car…
There are several soil monitor sensors available that can be easily interfaced with the Arduino or other Embedded modules and can be programmed for different types of projects such as Smart Agriculture Monitoring System. The problem is not having a combined, retrofit module that can easily be used in different projects or applications as needed…
A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a simple module. Most of the digital circuits or embedded circuits have a standard operating voltage of either 5V or 3.3V, so I decided to build a Power supply which can supply 5V/3.…
In our day-to-day life, we use various gadgets such as television, set-top boxes, air conditioners, home theatre, DVD players, and many other remote-operated devices. Different gadgets means maintaining different remote controls which are not only clumsy but also difficult to manage. Universal remote control simplifies our life because it helps us control any IR…
