[sdiy] Oscilloscope on a Budget 200

[Roman Sowa]

Or Hantek PSO2020 - it's cool little penscope, so you hold the little 
device in your hand, and instead of regular probe cable, there's USB cable.
In contrary to other USB scopes, there are physical controls on the 
device to adjust sensitivity, timebase, horizontal and vertical shift.
I have other 4-ch USB scope from Hantek and operating it with a mouse is 
such a pain that I use it only when I need 4 channels.

I don't have PSO2020 (yet, just foud out about it today) but it's so 
sweet I can't keep my $100 in my pocket not to buy it.
