I've been toying with an idea for a Rpi0 project, but I need a waterproof hard case for it- the project would require it to be wearable, waterproof, and shock resistant. I have an autistic daughter, and am considering a project to make a tracking bracelet that could be work on the wrist, ankle, or possibly as an attachment to some other personal item. If you're not familiar with the needs of such a device, what is needed is more than *just* a tracker, and there is a huge need, as it can benefit elderly patients suffering with all kinds of dementia, Alzheimer's, etc.
I have searched and don't see anything on the market that would fit- does anyone know of any cases, or could anyone offer "getting started" advice on how to even design such a case? I have access to various CAD packages but simply don't know how to get the wheels off the ground for something like this- I'd appreciate any advice.
