Below is our huge collection of 200+ free electronic circuits that you can build today.
Audio content has come a long way over the past decades, from a classic tube amp to modern-day media players, technological advancements have changed the way digital media is consumed. Among all these innovations, portable media players have become one of the first choices among consumers, because of their vibrant sound quality and long battery life. So how does it work, and…
This comprehensive BMS circuit diagram guide explains the features and working of a 4S 40A Battery Management System (BMS) commonly used with 18650 Li-ion cells. We'll explore the complete BMS circuit for lithium-ion battery applications, including detailed schematics, component analysis, and protection mechanisms. This lithium battery BMS circuit diagram breakdown includes…
For those who have a keen interest in gardening, a garden light would provide an option to admire the beauty of their plants even during the night time. These lights will normally be placed inside the garden, far from electrical outlets because it is not a good idea to run wires through your garden soil which will be wet and toiled most of the time. This is where Solar-…
In this tutorial, we are going to build a Lithium Battery Charger & Booster Module by combining the TP4056 Li-Ion Battery Charger IC and FP6291 Boost Converter IC for a single-cell Lithium battery. A battery module like this will be very useful when powering our electronic projects with lithium batteries. The module can safely charge a lithium battery and boost its…
Oftentimes in an electronic circuit, it's absolutely necessary to use a special protection unit to protect the circuit from overvoltage, overcurrent, transient voltage, and reverse polarity and so on. So, to protect the circuit from these surges, Richtek Semiconductor introduced the RT1720A IC which is an oversimplified protection IC designed to meet the needs. The low-cost…
An audio amplifier is an Electronic circuit that amplifies low-power audio signals to a level suitable for driving Loudspeaker. These Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds. There are many classes of Amplifiers and we have previously built a lot of Audio Amplifier circuits ranging from small…
Raspberry Pi-based systems require internet connectivity to work at full potential, this is especially true for applications like IoT, image processing, remote sensing, and other cloud-based applications. Consider the case below: You need humidity sensor data in an agricultural field 200 meters away from your control unit, but there is no internet access or a power outlet in…
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…
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…
As far as we know, Drones are unmanned aerial or flying robots that can be controlled from a base station or autonomously navigated by a software-controlled flight plan that is in its embedded systems. It can have onboard sensors and GPS. Nowadays drones are being used in many applications like photography, surveillance, search and rescue, fire fighting, traffic monitoring,…
The TDA7294 IC is a popular sound amplifier IC with low cost that has a ton of power handling capacity, 100W to be exact. For this tutorial, we are going to use two of those TDA7294 ICs in a bridge configuration to build an even more powerful amp that can handle up to 170W of RMS power. Throughout this tutorial we will walk you through the…
The flight controller is the brain of a drone as it monitors and controls everything the drone does. KK2.1.5 and CC3D are widely used flight controllers in drones. In our previous tutorial, we have used KK2.1.5 Flight Controller to fly a drone. You don’t require any PC to set up the KK2.1.5 flight controller as it comes with an inbuilt screen and we can set up this…
