Safe and Sound : Winter/Cold Weather Survival Suit Blog#9

dwinhold

This update is about water proofing my project. Everything done here is the first time I ever worked with this product and it was done live, so if it fails we will all see it go wrong. There are 3 videos attached, the first is showing the product, second is applying it to the board and third is putting the powered board under running water.

 

I use an Arduino Uno as a test so if this doesn't work I don't wreck the MSP432.

 

So, what do you think? Will it work? Fail? Here is the challenge, post below before you watch the last video and say weather you think it worked or if I ruined my Arduino Uno. Don't give it away (at least for a couple of days) after you watch.

 

Video #1 (The Acrylic Conformal Coating)

 

 

 

Video #2 (Spraying it on the board) **As a note - Take every safety precaution when using this, it is poisonous**

 

 

Video #3 (Water testing)

 

 

Hope you enjoyed watching.

    By the point of view of the protection I think that it is not needed to check the coated board; it is sufficient to make tests with a conductive surface and see what happens with different environmental agents like salt water, basic water, acid water, several organics etc.

    Instead I am curious too to see what happens in a real non-conventional environment (like a sera boat) to all the non-coated parts, like the USB connector, just to mention one.

     

    I can say that there is a series of technical specifications that means that some electronic components or tools are certified to operate in marine environments. This is a complex world I worked with a client in Genova (Italy) in the mid of '80s. Just as an example, the following link is a list of some providers of this kind of components: Military Specification, Aerospace, Marine, Automotive Electronic Components on ThomasNet.com

    I have no t found the regulatory specifications but can be found on the Internet.
