This bracelet is an upgrade from other versions I have been modifying to add attachments to it, as circuits and arduinos. You can always modify it. I use copper wire to join the parts, also some magnets to attach the add ons. In one of the pic's you can see I added a battery attachment with a flash light ring, it will be modify to be a wearable part.
