Assembling your own drone controller is more of a project that should be in a well-equipped robotics laboratory, not on your kitchen table. But here’s the thing, it’s more achievable than most people think, even if you’re working with a modest budget and learning as you go. Thousands of hobbyists, makers have done exactly this, […]
Walk into almost any attic, basement, or storage closet and you will find a small museum of forgotten technology. There is usually a clock radio that once woke someone up for work every morning, a cassette player that fueled road trips, or a VCR that still holds a half-finished movie inside. Many of these devices […]
While a BCD adder performs decimal addition using binary hardware with correction logic, a BCD subtractor performs the subtraction of one BCD number from another and produces a valid BCD result. This requires additional logic because simple binary subtraction does not automatically produce valid BCD outputs. Digital systems frequently need to perform arithmetic operations such […]
When you pause to consider why your smartphone starts behaving erratically after exposure to bathroom steam, or why an inexpensive kitchen timer fails after spending months near a hot stove, you are touching on one of the most demanding disciplines in electronics engineering: designing systems that can survive in harsh environments. Few environments are as […]
Let’s explore the BCD Adder Circuit and learn how it adds decimal digits using Binary Coded Decimal (BCD), a digital coding system in which each decimal digit is represented using a 4-bit binary number. BCD arithmetic is widely used in digital systems where calculations must remain in decimal form, such as calculators, clocks, and display-based […]
Voltage multiplier circuit forms a fundamental building block in high-voltage power supplies where the output voltage must be several times greater than the peak input voltage, yet the load current required is relatively small. Instead of using high-turn-ratio transformers which are large, expensive, and limited by insulation and core saturation constraints engineers often implement multipliers […]
