While you may be correct in some of these assumptions, the repo is open source, contains actual schematics and code, appears to have real community contributions, and also happens to exists now, which is something that can't be said for the original post this was a response to. I was hoping to just provide some reference to existing work that I found interesting since it is what I think is a much more traditional type of detection system.
