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…
Electrical Grid is one of the most important achievements of recent history. Here, the grid denotes the whole network, right from the powerhouse where energy is generated all the way to our house where energy is utilized, and everything in between. However, the rise in renewable energy generation and growth in distributed energy resources have caused technical…
Switched-mode power supply circuits (SMPS) are most often required in many electronic designs to convert the AC mains voltage to a suitable level of DC voltage for the device to operate. This type of AC-DC converter takes in the 230V/110V AC mains voltage as input and converts it to low-level DC voltage by switching it, hence the name switch-mode power supply. We have…
In this DIY project article, we will build a simple, cost-effective, powerful LED driver circuit that could be useful to power up an entire 12V light string that has more than 100 or even 200 LEDs. As there are many led driver projects that we have covered on our website, this is a very miniature version and can only be used for lighting a LED strip.

As the economy started bouncing back post COVID second wave, India is now gearing up for its festive season, but amid the festivals, the country is facing impediments of power shortage and outages in numerous states. A lot of thermal power plants such as National Thermal Power Corporation (NTPC) have proclaimed that they are in the middle of a huge coal shortage, but at the…
In this article, we will see how to design a simple 12V Li-Ion battery pack and how to use it with a protection circuit. A lithum-Ion battery is one of the most commonly used energy storage devices employed for powering equipment and gadgets in today’s time. Due to a high energy density and rechargeable capabilities, Li-ion cells are…
Switching Mode Power Supply, or simply SMPS, is a type of Power Supply Unit (PSU) that uses a switching device (such as a transistor or MOSFET) to convert the source, which can be AC or DC, to a constant DC voltage. Switched-mode power supply circuits (SMPS) are most often required in many electronic designs to convert the AC mains voltage to a suitable level of DC voltage…
In this project, we are going to make a 2S charger module using the MCP73844 module from the microchip. The charger is capable of taking voltage between 2-12Volts and charge Li-ion and Li-Po batteries in a 2S configuration. The aim of this project is to develop a charging circuit that can be used as a subsystem in any consumer-grade project. The charger module can be…
