I built a thing: DSO138 Oscilloscope (from kit)

I built a thing.

This is a DSO 138 Oscilloscope kit.  I assembled it last night, and to my shock and amazement, it works!

I got the kit from HobbyKing, but it's almost the same price at Amazon. The kit was awesome, with fantastic documentation.  I think it might have been missing one resistor, but it's possible that I could have dropped the missing one.  (Cluttered workbenches like to eat parts.)

Now I have to learn how to use an oscilloscope.  I'd also like to make or 3d print a case for it.
