This is a nifty little oscilloscope -- I got one for my brother, who works in a small electronics company.  The DSO Nano was quite a hit there -- the engineers/techs were pretty fascinated.

One of the more useful add-ons that you can make in your lab is an RCA-to-3.5mm jack cable.  I wanted to make a BNC-to-3.5mm jack adaptor to go with some proper oscilloscope 1x/10x probes.  There were no stand-alone BNC jacks, so I picked up a BNC-to-RCA adaptor and made a jumper cable to go from an RCA to 3.5mm stereo jack.
It so happens that an RCA-to-3.5mm jack is perfect for a device that measures kilohertz frequencies -- audio applications typically use RCA cables, so the oscilloscope plugs right in to the RCA audio output.  Accidental success!

I am really considering getting one. However, I am afraid that I will be irritated because it has not got 2 ports so you cannot compare in & out, left & right etc..

Small review of the DSO Nano here: http://letsmakerobots.com/node/18767


I'm guessing that if you need 2 channels, this may be the wrong scope :(  It's too bad there aren't more of these with different options.  

I notice that a Parallax USB oscilloscope (either the $250 USD or $140 USD version) plus shipping to Europe has a comparable cost to getting 2 DSO Nanos (two seperate, physically isolated channels).  If I can't think of a reason why this wouldn't work (can a  2-channel scope share a trigger pulse?), I think it means I don't know enough about oscilloscopes.


I've also seen this scope somewhere recently. But the manufacturer's web site and all shops I visited told me that they are out of stock. Seems to be kinda bestseller...

There are several places that stock it.
