If you design printed circuit boards, then you will have also redesigned printed circuit boards. Nobody gets it right the first time, every time. Sometimes you can solder a scrap of 30gauge wire, flip a component 180°, or make a TO-92 transistor do that little pirouette thing where the …read more
By now we are all used to the role of the printed circuit board in artwork, because of the burgeoning creativity in the conference and unofficial #BadgeLife electronic badge scenes. When the masters of electronic design tools turn their hand to producing for aesthetic rather than technical reasons, the results …read more

Right now you can get a custom circuit board delivered to your door in about a week for just a few dollars. There’s little reason to make your own circuit boards at home anymore, but when you need a board now, you want to have that capability. [tuval] designed a …read more
When designing a printed circuit board, there are certain rules. You should place decoupling capacitors near the power pins to each chip. Your ground planes should be one gigantic fill of copper; two ground planes connected by a single trace is better known as an antenna. Analog sections should be …read more
It is getting so easy to order a finished printed circuit board that it is tough to justify building your own. But sometimes you really need a board right now. Or maybe you need a lot of fast iterations so you can’t wait for the postal service. [Thomas Sanladerer] shows …read more
When the Magic Smoke is released, chances are pretty good that you’ve got some component-level diagnosis to do. It’s usually not that hard to find the faulty part, charred and crusty as it likely appears. In that case, some snips, a new non-crusty part, and a little solder are usually enough to get you back in business.
But what if the smoke came not from a component but from the PCB itself? [Happymacer] chanced upon this sorry situation in a power supply for an electric gate opener. Basking in the Australian sunshine for a few years, the opener started acting …read more
We are now in a golden age of printed circuit boards. It wasn’t too long ago that making your own circuit boards either involved a lot of money, or slightly less money and using some proprietary garbage PCB layout tool. Now, every board house speaks Gerber, and you can get a ten-pack of PCBs from China for five bucks. This incredible cost reduction means people are making art with printed circuit boards. We’ve seen portraits, landscapes, and memes. This is truly the beginning of a new artistic medium rendered in fiberglass and soldermask.
Check out this blinky bit of art …read more
Some people want everything on the cloud, while others refuse to put even the smallest scrap of data on the Internet. Most of us fall somewhere in between. A few years ago, we talked about a few cloud-based PCB layout programs including one called EasyEDA. We were impressed because it was a full package: schematic capture, simulation, and PCB layout. It was free to use, although they would give you a quote for producing your boards, though you were under no obligation to buy them. Of course things change in two years, so if you are curious how EasyEDA is …read more
[Marko] styles himself as a crazy chemist. His video showing a fast tin plating solution for PCBs (YouTube, see below) doesn’t seem so crazy. We will admit, though, it uses some things that you might have to search for.
The formula calls for stannous chloride — you could probably make this by dissolving tin in hydrochloric acid. There’s also thiourea — the main chemical in silver-cleaning dips like Tarn-X. Sulphuric acid and deionized water round out the recipe.
It probably goes without saying, that you shouldn’t be handling these nasty chemicals without the right set up and a good idea …read more
Making your own printed circuit board at home often leads to a board which looks homemade. Exposed copper is one of the tell-tale signs. That may be your aesthetic and we won’t cramp your style, but exposed copper is harder to solder than tinned copper and it likes to oxidize over time. Tinning at home can bring you a step closer to having a full-featured board. In the video after the break, famed chemist [nurdrage] shows us how to make tinning solution at home in the video below the break.
There are only three ingredients to make the solution and …read more
