You don’t have to be a nerd or an electrical engineer to build your own electronic circuit. With so many books and websites out there that provides circuit board designs and the basics of lining up your circuit boards with transistors, capacitors, and resistors not to mention using the soldering iron to melt lead, it can be virtually easy and a whole lot of fun to create your own electronic circuit and device. Here are some things that you should know about in order to build your very own electronic circuit. Who knows, you may be able to build your own high speed computer later on.
- Install a circuit design application. Whether you are using an Intel based PC with Windows XP, Vista, or 7 as the operating system or using a plain and sleek Mac, there are electronic circuit design applications you can use to create your own circuit design. Executing a quick search on Google should garner you a multitude of options however, going with Cadsoft’s Eagle layout editor is probably the way to go. You can download the program from cadsoft.de. Bear in mind that most of these types of programs are never free and will require you to pay certain fees but Eagle layout editor is freeware, which is why it is a top choice. Once the download is completed, install the software.
- Start designing. Using the software, you can actually create your own electronic circuit from scratch. Of course, you will need to know a little more than merely the basics to pull this off. Instead, scour the web for websites that allow users to download various commercial PCB schematics from which you can base your electronic circuit on. Download one and print it out. Use the schematic to design the circuit on your computer using the Eagle layout editor you just installed.
- Use the same dimensions. Measure the dimensions of your PCB schematics and use the same spacing on your electronic circuit design. This will include the spacing between resistors, capacitors, transistors, and the like.
- Add to the design. If you are pretty much learned in the ways of circuit boards and such, then you may want to add certain aspects and items outside the realm of the PCB schematic you based your design on. Plot it in the design. In the end, print the design out and use it to create your circuit board.
- Use a bread board. After printing your design, get a bread board and all the small items for your design ready. Place the printed design on top of the bread board and start placing the various pins, resistors, and capacitors through the design down to the bread board. Complete the design on the bread board and you now have your prototype. From here, you can already test if the circuit will work and if the voltages are right before finalizing it on the actual circuit board.
As soon as the tests succeed, transfer the design on the board to finalize the circuit. You will probably need some help in this aspect but if you are skilled in tracing the circuit routes and soldering the components on the board, you should be able to do it satisfactorily by yourself.
