So, one day I thought I felt that my helmet had become noisier. Weird, because I have a deflector on my windsheld AND I'm quite short. When I stopped to refuel I realized that the bluetooth plug had fallen off:



I thought that replacements might be avaliable, but having a 3D printer and skills, it was just easier to take some measurements and make a new one.
That turned into a downward spiral of creativity I hadn't planned at all... :033:

The thing is, I have an internal bluetooth (Just Speak) because I hate the bulkyness of the external ones. The only drawback is that for charging I have to fully open the helmet and remove a foam flap to access the microUSB port, wich is slightly annoying.
As you can guess, while working on the plug I wondered..."Can I add a microUSB port to the plug and connect it to the inside of the helmet?"
Well...it seems I can:



So I proceeded to design a flexible PCB to connect it to the inside. A few weeks later:



Looking awesome:



HOWEVER*2...

Now that I had made it chargeable from the outside, I could not monitor the status led of the device, and that kinda killed the mood a bit.
Soo...
I added fiber optics to the thing:



From the outside:



Nice, right?!

HOWEVER*3...

Now that it looked awesome, the removable waterproofh-ish flap didn't look right. It could be easily lost if charging on the fly and you threw the flap in a pocket. That's  bad practice, methinks.
Sooooooo...
I added a retention flap on the plug:





And now I'm happy with it.
I have leftover pcb's and pieces, should someone need one, BUT this is a very handmade piece so it is not cheap by any standards.

Hah! there is not that much skill involved, seriously, just good measuring for critical components, like the microUSB connector holes.
It was just a "measure and replicate" thing. (then it got wild, but whatever, you get the point). I also did it in various iterations, not everything at once, so it's not like I am that smart to foresee all that will be done.

FINISHED!

Finally, the fiber optics and V2 circuit board arrived! I had the printed pieces ready printed a few weeks ago, so I only had to solder, flare and install:



Installed with the non removable lid open:



And closed:



The insides are pretty clean now:



I can sleep now! ^^

Thanks!
I wear it pretty proud, even if it's almost invisible. ^^

Nice work! Looks like original fit, if not better 👍
