Recently, analog displays have come back in vogue. This is partially due to the common steam punk theme that is popular right now. [Cristiano] has done an analog display, but instead of brass and polished wood, he’s gone automotive themed with it. He purchased a cheap tachometer from ebay. A circuit had to be designed to give the tach the signals needed for it to operate, and you can download the schematic from his site. As you can see in the video above, it works well. We think that “shift” light might get annoying pretty quickly.
