I found this project in a reddit post a while ago and I loved the idea. I wanted an oscilloscope for quite a while but what I actually needed was mostly something to check if there's a signal at all. This little project seemed perfect for the task and since I just started working with KiCad I decided to turn it into a board.
After recreating the schematics in KiCad I got the idea to make an Arduino UNO shield since I had a few Arduinos in my drawer anyway. I ordered the parts I still needed and started designing the board. It actually took a few iterations to decide on a final design but here is the result!
I made a few changes from the original project:
Version 1.0 was was still too big. When Peter made the original design it was based on an Arduino Nano which of course is a lot smaller than the Uno.
I chose to make an Uno shield at first because I had spare Unos - But then I thought I should try to make it smaller. Maybe even smaller than Peters original version?
I wanted to keep the extra button and also the BNC connector but I replaced the latter with a horizontal one as the vertical one is kinda annoying because the cable is always in the way.
After playing with a few different designs I decided for a vertical version. A friend offered to design a 3D-printable case for it so that will hopefully be available as well at some point!
Everything else is basically still the same. I just moved stuff around, most of it under the display - in the first version that was mostly dead space. Also fitting everything around the contacts of the Nano was a nice little challenge but I think I got quite good with this kind of puzzle by now and the board turned out very neat and tidy in my opinion.
