There are many electronic component distributors with online stores. Here is a list of my favorites and what I like and do not like about them. [Read more…]
This electronic component guide will try to explain in a very simple way how common electronic components work. This guide includes the following electronic components:
- Integrated Circuit (IC)
Please note that this electronic component guide is only meant as a very simple introduction to some of the components you will encounter when building electronic circuits.
NOTE: I’ve written an updated guide to the basic electronic components. I highly recommend it if you want to understand how each component work.
I have compiled this list of online resources that offer free electronic circuits. The circuits include free schematics and many of them also include explanations on how the circuit works and pcb layout. [Read more…]
To know how to desolder a solder joint is maybe just as important as knowing how to solder.
Sometimes you need to make a correction to your electronic circuit. Maybe you soldered a diode in the wrong direction or maybe two of your pads have accidentally been connected by some extra solder.
In these cases you need to know desoldering. [Read more…]
Before you send your board layout to PCB manufacturing, you should always check your board for errors. There is always a chance of errors when you design a board. Very often there are mistakes on a board. And very often you don’t discover it before you have manufactured the circuit board and are trying to troubleshoot it. [Read more…]
This is my step-by-step guide to schematic drawing in Eagle. Let us say we find the circuit above interesting and want to build a real electronic circuit out of it to test in the real world. The first step is [Read more…]
To be able to read schematics you must know the schematic symbols. Here is an overview of the most used symbols in circuit diagrams. [Read more…]
You don’t need fancy equipment to do SMD soldering at home. You can easily do it using a soldering iron.
SMD stands for Surface Mount Device and they are components that you solder on the surface of a circuit board.
Let me guide you through how to do SMD soldering with a soldering iron.
