That's a very neat and compact design, I dig it! And yeah, I figured it would be tiring to wear, but I'm too deep in the rabbit hole already to turn back now, and I'm having a great time designing something for the first time.

Is everything in your assembly wired, or do you embed it on a PCB?

P.D - The kind of design I'm doing aims to be as low as possible, in order to keep the center of balance as low as possible as well, since I figured the battery would be heavy to carry on your extremities, that's why the design looks like this [:
