There are different types of DC-DC regulators. The most common are linear and switch mode regulators. Everyone that has tinkered with electronics has probably used a 78xx series linear regulator. They are easy to use since they don’t need any special components. With most linear regulators you just put a capacitor on the input and
First of all You won’t find here any information on high speed BLDC motor driving. For that purpose You need to know rotor’s position, so You have to measure back-EMF or use Hall sensors (not needed here). For basic info about driving BLDC motors here is best “classic” articles on internets: Driving a three-phase brushless

Have you come out of a store and said to yourself, where did I park my car? Well, I have. Now, there are a lot of smartphone applications that can help you locate your car but smartphones are expensive. So this Lazy Old Geek (L.O.G.) decided to make my own. How It Works: When you
The use of low-dropout regulators, popularly known as LDOs, is common in many applications today because they provide a simple and inexpensive way to regulate an output voltage that is stepped-down from a higher input voltage. In addition, linear LDO voltage regulators contribute very-low noise as compared to switching regulators. Nonetheless, to keep system power
Selecting the Right Ultra-Low Quiescent-Current LDO Regulator Continue Reading
WARNING!! You will play with LIVE MAINS!! Deadly zone!! If you don’t have any experience and are not qualified for working with MAINS power I will not ecourage you to play arround! Because of the high interest in the subject, a new dedicated Dev Board has been born: MPSMv2, a small ESP8266 DevBoard with integrated
How it all begun Hi, my name is Alex Sardo. I am the founder of World Class Technologies an innovative Software and Hardware design company which develops custom designed solutions for various markets and communities. I can’t remember how many times I wanted to embed an OLED display into a project, or perhaps design a
