Here is a simple audio amplifier circuit based on TDA2050 IC. This amplifier can deliver an output power of around 15W for an 8-ohm load, 18W speaker with 18V DC power supply. Circuit and working The circuit diagram of the TDA2050-based...
To keep pace with the new technologies like the Internet of Things, Artificial Intelligence and 5G spectrum, the wireless technologies are also getting upgraded. Here is a peek at what’s happening in the areas of short-range as well as...
Smart presentation pointers are readily available in the market but are expensive. Here is a simple, easy-to-build, inexpensive and infrared (IR)-based smart slide pointer using Arduino Leonardo. Slide presentations using PowerPoint can be frustrating because you may need to click...
The triboelectric nanogenerator (TENG) is a fascinating technology that dramatically speeds up healing. It reduces healing time to one-fourth of the normal healing process. It can heal even nasty wounds of a diabetic patient. Moreover, the bio-degradable triboelectric nanogenerator...
The circuit presented here can measure voltage (V), current (A) and wattage (W) on an OLED. It is actually voltmeter, ammeter and wattmeter circuits combined in one unit. It is a useful tool for testing circuits, desktop power supplies,...
Most power-resumption alarm devices produce non-stop alarm when power resumes. To overcome this problem, here is an automatic Power-Resumption alarm circuit that sounds an alarm for a few seconds only after power resumes. Author’s prototype is shown in Fig. 1. Circuit...
As artificial intelligence (AI) continues to evolve and expand, companies are seeing huge changes in the field of aviation. Big brands are investing in AI technology to enhance their products and services to better serve their customers. Artificial intelligence (AI)...
The process of making a three-dimensional (3D) solid object from a digital file is known as 3D printing or additive manufacturing. A 3D object is created through an additive process, which means laying down successive layers of material until...
Engineers are always in search of projects, and finding meaningful projects makes that search worthwhile. Listed below are some electrical engineering project ideas for such engineers. A lot of them may deal in a higher power than electronics engineers...
As environmental concerns over global warming escalate, there is a worldwide shift towards cleaner fuels for power generation for sustainable development of smart cities. Aerostrovilos Energy, an IIT-Madras incubated startup founded by Rohit Grover, Pradeep T., Suresh M. and...
