Of course you can take a black box with no holes and a cable gland and use it as a weatherproof case but there are some topics which could give you headache regarding just the sealing without talking about the fixing of the components - that topic we will discuss later.
So questions come up like:
How to use audio devices?
How to prevent condensation inside the case?
How to reopen the case? (when glued together to make it waterproof)
How to regulate temperature?
How to install a camera?
Let's start with the separate components of the INcase and how they are fixed together and how they become weatherproof.
We use solid metal thread inserts and metal screws on the other side to combine two modules (e.g. front & back) with each other. We did not want to use plastic clips because they break often while working with it and you can't finish your work.
And after years when you want to upgrade your board you can easily reopen and close it again as if it is new.
A sustainable case isn't it?
Now the actual sealings which are only added to the PRO (outdoor) version - the BASIC (indoor) version therefore has none of the following sealing parts.
- A silicone band in the gap of the case module tightens enough when screwed so no water can enter the case through these gaps.
- A glued glass in the front gives more flexibility and the possibility to install a camera or other visual parts which could also mean that you fix there a display, a seven segment display or a signal LED and so on.
- The holes for the 2 way audio are covered from inside with a PTFE textile piece also known as "gore tex". This method is also used by smartphone manufacturers to make the phones pretty water resistent though we know it is not fully water proof because you are not allowed to dive with it. But rain in our constellation is no problem - that is why we call it "weather proof"
The gore tex stops water but lets air through which is positive for air circulation and prevents condensation inside the case.
