Ok so here's what my brain just made up just now:
Most dvd cans have the third pin for the PD which is used to send some kind of feedback to the APC circuit to regulate the power the diode is getting.(right? :-/)
So I thought , wouldn't it be possible to hook this photodiode up to your circuit and add a tiny and sensitive digital voltmeter that you could tune with the help of the pot so that it displays the laser's power, right on your unit This would be totally cool if it actually worked, but it's just a theory.I didn't go deep into any research yet because I want to see if someone has a good strong reason for why this wouldn't work.So what do you think?
