There is no better way to learn electronics than building and programming your own gadgets with Raspberry Pi, Arduino, and other similar platforms. PiGlass is a wearable computer that lets you capture videos and have them uploaded to Dropbox via WiFi. It also lets you stream music from your phone via Bluetooth.
As Adafruit explains, you can add a bone conduction transducer to PiGlass. The camera on it can be used for livestreaming to YouTube. To build this, you are going to need a Pi Zero W, Bluetooth dongle, Pi Zero Spy Cam, safety goggles, VuFine+ wearable display, and a few other parts.[where to find instructions]
