Keep in mind that I dont know the least about electronics. I have soldered and used some arduinos before, but that is it.
I am preparing to make a mechanical keyboard (or handwire like they say on /r/mk) and the common solution for registering keys is a diode matrix, which will be connected to a teensy board, under a custom-designed aluminum case.
But how can one protect this kind of structure from spillings ? What component, precisely, is vulnerable to water ? Pcbs are is'nt it ? so this mainly applies to the teensy ?
If that is true, would encasing the teensy solve the problem ?
Maybe water would make some component rust, like the case, or the diodes' anodes and cathodes.(Though aluminum should not be damaged by some water i guess)
That makes me realise there should be plural types of damages occasioned, so what other damages would a water or a coffee spilling do on my keyboard, and how can i protect it ? and of course, how much would it cost ?
