Dusty electronics

I've been taking mine outside and blowing them off with compressed air at 150 psi.

Every once in a while I'll blow some components away. ?

But over all it's been working pretty well.  I've even blown off complete breadboard circuits without blowing components away.   But you do need to take care with something that fragile.   I even blow out my lap top computers.  Especially the fans.   The amount of dust and garbage that comes out of those fans is amazing.  I actually do this fairly  often.   But  you do need to be careful  that you don't damage something with the strong air blast.

But it works far better than trying to vacuum the boards.   I blow off Arduino and Raspberry pies all the time and haven't had an issue yet.   One trick I've learned is to start by holding the blow gun far away and then coming in closer until you feel like the pressure might potentially damage something.

If  you put the air gun right up against the board and pull the trigger point blank you can easily break something.  That's a lot of air pressure to be blasting that close out of the blue.  So start far away and get as close as you dare.  Works way better than a vacuum cleaner.  At least for me.

By the way, I would recommend using lower pressure.   Maybe around 40 psi?  I use the full 150 psi.  But like I say, you need to start far away and get a feel for how close you can get before you might do damage.

Also, don't blow off any important CDs.    I've actually blown painted labels clean off CDs.  So be careful with those.  I do blow out my CD players though.  Just be sure to take all the CDs out first.

The other thing I do for prevention is keep most of my electronics in plastic zip-lock bags.  They aren't anti-static though, so you need to be care about that.  How much you can get away with can depend on where you live and what the static electricity is like in your environment.   Best bet is to buy anti-static bags.

That does sound like a good idea I'll have to get some canned air my compressors are loaded with water and air nailer oil they have been in the field of operations for a long time? . I wonder if a wood box would work for storing electronics  it seems to be low static hmmmmm.
