Oscilloscope Clock and Bluetooth Speaker

This is a heavily modified kit that converts an analogue oscilloscope into a clock. Almost the only part left of the original kit is the driver board.

This uses an ESP32 that drives the internal DACs to steer the X & Y beam. I completely rewrote the software and added expanded the original memory from 4Mb to 16Mb. I also wrote a Bluetooth A2DP stack and added an amplifier and speakers. If I connect a Bluetooth audio player I can stream the music to the speakers and see the music visualized on the screen.

The video shows some oscilloscope music being played. This is music specifically designed to also draw graphics on an oscilloscope like this one.
