DSO201is a pocket size digital storage oscilloscope fulfills basic 
electronic engineering requirements. It is base on 
ARMCortex™-M3compatible 32 bit platform, equipped with 320*240 color 
display, SD card capability, USB connection, and chargeable batteries. 
Weighs only 60g!Portable Digital Oscilloscope DIY Kit provides waveform 
viewing, pocket size and over 2 hoursbatteryoperation. This DIY kit is 
aopen source code. The Schematic, PCB layout and program code is free 
for re-design. It is ideal for production test, research, design and 
education.

... looks like a modiefied MP3 player case.
Ever thought about building an extension header board for STM32 Primer2? 
Porting the oscilloscpoe firmware should not be too hard ...

[Stefan V. (vollmars)]

Interesting project,
but only one analog channel (why?), maximum amplification, independent 
from input sensity, so you should get plenty of noise.
Do you sell it?

So this is a toy?
There is no use for just 1MHz.
