Display Turntable speed with an Arduino Nano

Ah, same OLED that I used on one of the prototypes. I may someday try to find the optimum OLED display for My tach use but too many projects going right now. 🙂

Has anyone built one of these that might fit in the window of a Thorens TD124? I saw a picture of a digital tachometer on USAM, sold a while ago…

So how big is the window in the Thorens? These Tachometers and be built for less than $50 and with the OLED can be built pretty small.

without pulling it out of the table, according to online sources the strobe mirror is 2 3/16" X 1 1/4". I’d even be open to a member who had assembled one recently and would be open to doing another.
