Episode 51 of my ’76 Mazda Cosmo restoration is here! First, let’s talk length. That’s what she said. I know it’s ridiculously long. The title of my sex tape. Thing is, this video contains the entirety of final assembly of the electronic instrument cluster and it was an ordeal. Stuff broke, mistakes were made, more stuff broke, and add a long wait for replacement parts.And then I had the joy of reliving it all while editing this monstrosity. I could have split it into two, but then that would extend the instrument cluster to 6 parts and I just wouldn’t have it. So dear viewer, I implore you to have the same experience watching it as I had making it. But here’s the thing: it worked out rather well and even though I have months of programming to make this cluster actually do anything more than twiddle the needles, I think it was worth it.
