<p>This is a tiny Bluetooth speaker system designed as a "kitchen speaker".<br/> Assembly requires following parts and a bit of soldering.</p> <ul> <li>1 x Bluetooth Receiver: <a href="http://www.tinyosshop.com/index.php?route=product/product&product_id=792">TinySine Bluetooth Receiver Board</a> @Amazon.</li> <li>1 x Amplifier: <a href="https://www.adafruit.com/product/987">Adafruit Stereo 3.7W Class D Audio Amplifier MAX98306</a> @Amazon.</li> <li>2 x 1" Speaker drivers <a href="http://www.daytonaudio.com/index.php/dayton-audio-ce32a-4-1-1-4-mini-speaker-4-ohm.html">Dayton Audio CE32A</a> <a href="http://www.parts-express.com/dayton-audio-ce-series-ce32a-4-1-1-4-mini-speaker-4-ohm--285-103">@Parts Express</a>.</li> <li><p>(Optional) 2 x Small screws #4 3/8-in <a href="http://www.homedepot.com/p/Everbilt-4-x-3-8-in-Zinc-Plated-Steel-Phillips-Pan-Head-Sheet-Metal-Screw-16-per-Pack-812661/204275188">@HomeDepot</a>. Note:</p> </li> <li><p>Depending on printer accuracy or filament types, the lid might be a bit loose.
