Description

I saw this first in Maplin (UK electronics chain) priced at about £180. It seemed a lot for a 2-channel, 8 bit, 1MHz oscilloscope shipped without probes or charger, but it has some unusual features :

Wifi & internal battery for self-contained remote connection to a tablet or PC
Charges off USB (mini plug)
Supported on IOS, Android 4, Windows

And, much praise to Velleman for

Protocol description on manufacturers site

I had a need to monitor the signals on a friend's rotating machinery, so when I saw a brand new example of this on an auction site for 1/4 the listed price, I snapped it up.

Taking it apart, I broke it : the power button really needs to be removed first / fitted last, levering the board out without removing the button damaged the switch. A wire link fixes it for now. Beware!
