The flashing light circuit was the first circuit I ever built.
I was at home and probably around 14 years old at the time. I was walking between the television and my computer as I used to. I would surf the net, then I’d hear something interesting from the television which my mom and dad was watching and I would walk over to see.

Have you ever wondered how a relay works?
A relay is an electromechanical switch. It works in the same way as a manual switch, [Read more…] about A Guide To How A Relay Works
Did you know there are many types of resistors?
Your electronic schematic tells you that you need a resistor of 100k Ohms. Ok, so you go to an online store to buy one. But there you get all these choices: Thin film, carbon composition, metal film +++.
“Just give me a freaking 100k resistor man!”, you scream in despair.
Believe me, I know your frustration. It took me a long time to actually bother reading about different types of resistors. So I just chose random resistors for all my electronic circuits. Usually it worked flawlessly. Maybe I was lucky or maybe I just didn’t identify the resistor as the problem when I had a problem.
Anyway, my aim here is to provide a simple guide on how to choose a resistor without diving deep into details.
“What capacitor types should I choose?”
This is a question asked by many beginners. I will give you a simple answer to this question without going into all the details. After reading this, my goal is that you should be able to go and find the capacitor you need right away. [Read more…] about How to Choose the Right Capacitor Types Every Time
There are many PCB design software solutions available. The software you use should be able to draw both schematics and printed circuit boards.
These are my favorite free cross-platform programs available for Linux, Windows and Mac OS.
I have copied their own description of themselves from each of their websites. Just to give you an idea of what they are about (or at least how they like to present themselves). [Read more…] about PCB Design Software
