I've definitely spent $300 on a project that was only in the end for decoration, like my Gameboy Advace CM3 unit, and my Cinna-Minty Pi v3. Of course, now I have the steamdeck and modded vita to take the place of those, but it was still fun to build them.

My experience!

It's not as big a loss as it looks, because now I have have leftover supplies, which will help me talk myself into doing this all over again with a new project!
