Helmet has two compartments. Red is for comms and blue is for the batterry.
I'd put the battery into the 3D printed housing that locks with the existing tab in the compartment.
I haven't thought about waterproofing yet but it definitely needs it.

The programmer thing was meant as a joke. I have no intention on selling that shit. If it works I'll give them out to my riding buddies. I think I could definitely make them for under 50€ in BOM.
I'm a CS college dropout and my friends will help me when I'm stuck on something.
FFS I successfully implemented real time 3D audio in C++ during college, how hard can a bt connection with a phone be. I'm rusty as hell but I still have all my projects saved.
