Here are 5 cool circuit ideas for your next project. It feels so good to make cool stuff. So here is some inspiration for you to start building your next project.
This is a project I did that was really cool to make.
Making a cheap PCB is easier than you think. Here is short summary of how to create your layout and a list of some PCB manufacturers that you can choose from to get your circuit board manufactured.
Here are some simple PCB design guidelines that can help you create better board layouts.
There are always limits to how big your board can be, how thin your traces can be and the smallest drill size you can use.
This is a PCB design tutorial that I designed as a simple way to learn how to create a PCB layout in Cadsoft Eagle.
PCB Design is extremely useful to know. It’s what will take you from knowing how to build simple circuits to being able to build advanced stuff like LCD screens, Quadcopters, etc.
What you need for this tutorial:
(If you want to use the same schematic as used in this PCB tutorial you can download the schematic here. You can also find three simple electronic circuits with schematics, board layout and Gerber files here.)
We start by opening our schematic diagram in Eagle. Click on the “Board” button (or choose “Switch to board” from the “File” menu) to create a board for this schematic.You can also use the command line for selecting commands.
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.
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
Before you send your board layout to PCB manufacturing, you should always check your board for errors.
There is a high chance of errors when you design a new board. And very often you don’t discover it before you have manufactured the circuit board and are trying to troubleshoot it.
If you’re able to remove all errors before you make the board, you’ll save a lot of time!
Many errors can be removed by making sure your schematic is correct.
When you’re sure your schematic is correct, there are a few other checks you should do to minimize the chances of any problems.
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.
Here is a list of 5 of the best electronic blogs that I have found on the web.
Instead of reading about violence, crime, and corruption in the “normal” news every morning, I use an RSS feed reader and read about cool electronic projects from blogs around the world.
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.
