Here's what you'll need: - Both printed parts - 2 M3x8 to M3x12 bolts, cap head, pan head or similar - 4 M3x12 to M3x20 bolts, cap head, pan head or similar - Bits of jumper wire - Drill (optional) - A pair of speakers - Any Bluetooth-equipped device that can play music - Amplifier board http://amzn.to/1RnSQww - Boost converter http://amzn.to/1WMEFch - Bluetooth receiver http://amzn.to/1WMERIx (get the ones that look like USB flash drives) - LED voltmeter http://amzn.to/1UbM0yK - Speaker Terminal http://amzn.to/1RnU6zC (might not be the exact one) - Batteries & Accessories http://amzn.to/20x1D5B - Smaller compatible batteries http://amzn.to/1Vh5zYD - 2.6mm plugs https://goo.gl/g25PmP (not sure where else to find them - let me know if you have a source!) Assembly: Remove the miniature plugs from their housing and make sure they fit their holes. If not, widen the holes in the printed part with a drill. Solder bits of jumper wire into their ends and use some super glue to fix them in place. You can use a NP-F battery to guide them to their final position! Route the wires into the enclosure and wire up the components as seen in the video. The speaker terminal screws in with the two shorter screws to the side, the two case parts match up with the longer ones. If threading the screws into the plastic is too hard, use a M3 tap or a slightly larger drill to prepare the holes. Make sure none of the components short out each other and use Kapton or electrical tape to insulate them.
