Not A Number

The jyetech DSO Shell is a pretty neat little toy oscilloscope kit. It can only go to 100khz or so and is single channel, but it is actually fairly useful sometimes. Also, the fact it comes with schematics and source code is great for learning how scopes work.

The main issue with it is that it requires external power via a DC jack, which can be a pain. Like many people I decided to add a battery pack to mine. Not the prettiest, but it does give the scope a nice heft to it.
