[Ruvin Kub] likes magnets, a great deal. Most of his assignments aspect some form of magnet and his Computer board agitation bathtub is no exception. You can see a movie about the machine, under. We’ll confess our Russian is quite rusty, but if you ask YouTube properly it will translate the Russian subtitles into whatsoever language you like.
Just one of the issues we favored about the movie was that he utilizes hydrogen peroxide, citric acid, and salt as an etchant. We’ve observed the very same blend with vinegar or muriatic acid alternatively of citric acid. We are not absolutely sure what the actual translation is about why he does not like ferric chloride, but YouTube suggests, “she’s as well gloomy for my light-weight souls.”
There are a number of translation glitches, but overall the design and style is straightforward. A motor moves a very little see noticed in the base with magnets that repel very similar magnets in the tank. In that way, the electronics are isolated from the liquid. The full affair operates on a rechargeable battery.
As a reward, in the finish, there is a short tutorial on generating a board with toner transfer along with evaluating the time to etch the board with agitation and devoid of. Like a Tootsie Roll Pop, he lastly bought worn out of waiting around for the non-agitated board and completed it with agitation. The take a look at board that started off in the bathtub had been done for a long time.
If you want to try different etching answers, we’ve asked people to share their favorites. Or, just break out that CNC machine.
