Hi,
How could I implement photodiode(or must it be fled?) eye(s) to miller engine?
Assuming you by fled/FLED means a flashing LED, you can't, as they are very different components with very different functions (it's like asking if a resistor can be a substitute for a transistor).
Just take FLED 3.3K, 33k, .22uF and FLED module and put it on Miller SE?
FLED, FLED module - I really don't know what you're trying to say here, but the flashing LED is used as a trigger device.
You can use different trigger devices, but first you need to really understand the components you're working with - then you will be perhaps able to change a circuit.
Why do you want to change anything at all?
