Do you have a Raspberry Pi? Add this shield and you will also own a digital storage oscilloscope!
This shield offers all standard oscilloscope features and comes with the source code, so you can develop your own applications.
As a bonus, you also get a 10-channel logic analyzer, a great tool to monitor digital signals.
