Great project by the way, I'm currently looking into DIY scopes and have been researching the Miniscope v2c/v2d. I'm going to link to this project in my blog Pocket 'scope, which is a bit of a mess as I'm still looking into the subject. The DIY kits in that page may move to a separate page shortly.
The Ray's page has been updated and the link has moved to https://www.hackster.io/rayburne/10-arduino-o-scope-3b20cc. You should update your ReadMe.md on the front page.
