First off, before you bash me with the "there's no such thing as a good DIY oscilloscope" stuff...The intent of this project would not be to create the world's best oscilloscope, rather something to tinker around with and to examine basic waveforms...not critiquing the output of a SMPS or anything.
Disclaimer out of the way! Now the real topic. There's a possibility that you've run across this scope, and this might be old news, but for some reason, I do like the simplicity of it and the fact that I can build it from scratch. Specification wise, it's about equivalent to the popular JYE Tech oscilloscope kit. Same resolution screen and shares many other similarities.
The positive side is that you don't have to pay $60+ for about $20 in parts.
He's still working on it. A new firmware was released a few months ago. It's completely open by the looks of it.

Here's a video of it in action.

Any opinions on this? Any possible improvements you guys see? Some might say it's a waste of time, but somehow I think it might be interesting to try..as it can be literally a tiny fraction of the cost of any production meter...even the tiny pocket DSOs...
I do have a few questions about it, but I won't ask them until I'm dedicated to it.
Thanks!
