I saw a dimmer on instructables and try to create circuit and pcb for it. However the it looks nice and probably will work but I'm not confident the reliability on long run.
So my question would be if this design violates some safety rules or not.
Yes I know the resistors don't have value yet but I still analyzing the datasheets of the optocouplers and the triac I have. (Probably will result more question(s))
