This simple single-channel audio amplifier is built around 8-pin IC TDA 7052 and uses only a few other components. Two of these can be used as a stereo amplifier. The amplifier gives 1W output with a power supply of...
For most of the time having a real conversion with a computer has seemed something that was really far away, until now. Alexa voice service (AVS) is one such technology which helps to achieve this goal with IOT of...
Let’s look at some new Raspberry Pi project ideas for you to get busy with this year. X-Ray Based Covid -19 detection General X-Ray-based Covid-19 detection systems are fast and give quick results along with the status of how much the...
Raspberry Pi’s first board based on a single microcontroller chip, the Raspberry Pi Pico (Fig. 1), is designed for physical computing—similar in concept to an Arduino—ratherthan perform the role of a general-purpose computer (like the others in the range)....
At times, during multitasking, you would have wished to have more than two hands attached to your body, which you could control using your mind—just like you control your natural hands. But considering it as unrealistic, and only belonging...
Micropython on ESP8266 Micropython is very similar to python 3, only it is targeted for microcontrollers. So, if you know how to program in python, you will find it easy to start with micropython. Micropython also comes with an interactive...
Use of a room heater at night in winters can cause sleepless nights, dry skin, and allergy. Worse, it can prove a health hazard due to increase in level of carbon monoxide in the room. People with heart disease...
Many mini electronic modules are available in the market for providing quick plug-and-play solutions. We can use some of these modules to make a low-cost, portable, 15W public address (PA) system that includes a battery management system (BMS). Construction and...
Earlier, we made a futuristic wireless tile called Smart PowerTile that allowed home walls to wirelessly power electronic/electric devices, similar to a MagSafe. With this, a Raspberry Pi placed on a wall could be powered wirelessly. Proceeding with that concept,...
The circuit presented here can provide up to three amperes of current for a 5V, 6V, 8V, or 9V supply. It uses the popular adjustable voltage regulator LM317, which is inexpensive and is used generally for variable power supplies...
