&lt;p&gt;Recently we&amp;#39;ve been playing around with Bluetooth Low Energy, and in this application-based video we&amp;#39;ll look at how to put BLE streaming audio to use as a Halloween jump-scare device. I&amp;#39;ll show you how I used CasterSoundboard running on linux to trigger some sound effects, and how I integrated a class-D amplifier alongside a LiFePO4 battery to create a truly wireless solution. Now the question is, can we actually scare anyone???&lt;/p&gt;
