Wireless Speakers
This project housed a DIY wireless speaker system within a 3D printed case. The electronics inside include a battery from a cell phone, battery charger, USB step-up circuit, bluetooth audio driver, and two 12W speakers. I designed the case to be as small as possible, with buttons for the controller and easy access to the charging port. The side prodile is based off of a Reuleaux triangle. The speakers, controller, and charging circuit were glued in place, and the side panels are screwed in with countersunk 6-32 screws. The case is 150mm wide and 86mm tall.
