Tell us about yourself!
If you really want to deal with a graffiti "problem", then paint a mural. It'll get hit FAR less often.
After 1), what about capacitors? They can still hold charge, and possibly cause shorts during reimmersion. I guess they might be small enough not to worry about, but it might still be worth shorting the power contacts on the phone and any other obvious caps to make sure they are drained as much as possible before washing.
Yeah, no electronics are going to be happy after a night in salt water.
Depends how bad the damage is. If you've destroyed PCB traces, or killed components by shorting, they yep, it's probably stuffed. If not, a good clean and it should work fine, though if you've partially damaged traces, then they might corrode more over time (hence the washing part).
Is this the only arduino that has a removable chip?
It still says "Fresnel lens" in step 3.
Haha, you forgot https://en.wikipedia.org/wiki/Coffee_enema :P
Meh.. it looks nicer, but it only really has a couple of extra tools - the ruler and the box opener. The ruler and the spanners are double counted. The screw driver position looks better, but yours looks simpler over all, and less likely to go wrong... I think I would probably make it a bit thicker though, and maybe add a box cutter.
OP is male..
When is that a problem??
(I agree that more storage space in general is not necessarily good, but more tools never hurt).
