My Name is Nick Johnson from Arachnid Labs, and I'd like to introduce you to the
Tsunami.

The Tsunami is an Arduino-compatible development board with a Direct Digital
Synthesis chip onboard. This makes it an incredibly versatile signal generator
and frequency counter, and makes a plethora of other tasks possible too.

- Cut to pan of PCB -

Direct Digital Synthesis is a way of generating analog waveforms, like sine
