|ARM Oscilloscope DSO-201 Nano (Mini 2.8in) Digital Oscilloscope|
I figure building a really simple oscilloscope with an Arduino will let me learn the basics of how to use one. Plus if it does turn out to be useful I'll probably have a better idea of what kind of specs I'll need as there seems to be a big price difference depending on the sampling rate and number of inputs it has. Although in the $400 price range they start to come with a few more bells and whistles. Seems like that might be around the price range if I wanted one that would give me a little room to grow into it as I keep building bigger and ever more complicated circuits.
