Part 49 - Electronic Instrument Cluster Conversion - Part 3 - My 76 Mazda RX 5 Cosmo Restoration

It's been a long while, hasn't it? Who would have thought that retrofitting a 44 year old instrument cluster with modern electronics and building almost everything from scratch would be complicated? Yep, that's right. It's part 49 of my '76 Mazda Cosmo Restoration! And once again, I am continuing to work on the instrument cluster. This time I'm getting the final touches done by building the backlight boards, making the boards for the fuel and temp gauges, making some mistakes, and finishing up with all the cluster innards. It's another electronics episode mostly, which I know isn't my usual fare, however "electronics" is a big part of an electronic instrument cluster. And man, I'd have to say this is the most complicated single project I've done on this car so expect at least another episode to finish up the cluster.
