Hi
I have a optical RPM sensor like the one sold on the robotshop website:
Does anyone know of a display it will work with? Or another optical rpm senator that would fit a display sold here?
Intended use is a model jet engine, so I need optical and high rpm capability.
Any advice is appreciated 
Thank you
Erling
Hello @erlingwiig and welcome to the RobotShop community 
That optical RPM sensor works with the eLogger V4 which can connect to the PowerPanel LCD display also from Eagle tree systems. Or maybe if you own an Arduino you could do something like this:
and use a display like this one. You can find more options in the LCD & Display section, just make sure you look for one that uses the I2C protocol.
