Tauno Monitor

I have released a new version of the serial monitor application “Tauno Monitor” for Linux and added a “Clear” button and timestamps display option. The goal is to keep it simple and minimal.

Photocoupler PC817 circuit

My photocoupler (optocoupler) board design. I added four resistor places to combine them with different input and output voltages. Also added a diode for reverse voltage protection. Does the output side need it? Any other suggestions?
