Hacks of Electronics
Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
Modern electronic systems rely heavily on both digital and analog signals. While microcontrollers, computers, and digital processors handle data in binary (digital form), most real-world signals such as sound, temperature, pressure, and voltage are analog. To bridge this gap, Digital to Analog Converters (DACs) are used. A DAC takes digital input (binary numbers) and converts […]
In today’s world, most electronic devices operate digitally, but the signals we experience in the real world—such as sound, light, temperature, and pressure—are analog in nature. To process these signals in microcontrollers, digital signal processors (DSPs), or computers, we need to convert analog signals into digital form. This is where an Analog-to-Digital Converter (ADC) comes […]
Walking into a science fair, the projects that grab attention are the ones that move, blink, beep, or spark curiosity. Electronics projects do all of that and more. They’re practical, creative, and they give students a chance to show problem-solving skills in action. The best part? You don’t need to be a professional engineer to […]
If you’ve ever opened up an electronic device – anything from a laptop charger to a pair of gaming headphones – you’ll notice tiny components scattered across the board. Among them, the diode is one of the most essential. It doesn’t look like much, but it plays a massive role in how circuits behave and […]
Most people never think about transistors. They’re too small to see, hidden away inside the gadgets we use every day. But without them, modern electronics wouldn’t exist. From the phone in your pocket to the microwave in your kitchen, transistors quietly do the heavy lifting. So, what exactly are they, and where do you find […]
We’re surrounded by lots of “smart” things: phones that do more than we ever expected, apps that solve equations, graph functions with a tap, or even voice-command calculators. With all that power in our hands, it’s fair to wonder—are old-school electronic calculators still useful? Turns out, the answer is yes. The Invention of Electronic Calculators […]
