Thanks Ted! so it IS a diode!
Thanks Ted, that really helps
More problems ?
Oh yes! lol
still dont know what the red/white wire is for, for instance.
in the simulator i put a generic op amp (the only choice I have) but the AD706 in my circuit is a DUAL op amp so I guess it must be powered with a dual voltage.... and not as I did
dual = 2 op amp in one package
opps, sorry I meant BIPOLAR

Op amp can work in two modes or single mode of power supply.
google - dual supply op amp circuit and single supply
here is the schematics i was able to make
post # 1 top drawing, which wire is red and which white ?
from top to bottom:
left side:
yellow
white/red
green
red
on the right side:
black
I sent you a PM Ted
From top
IN - to control laser beam
OUT - signal from photodiode
- voltage supply
- voltage supply
Black
control bias op amp
The circuit is using only one op amp.
Double check your drawing - op amp is in strange configuration
google - ir thermometer circuit
great! but red wire is going straight into pin8 (v+) of the ic?? and green into pin1 (v-)... is there something i dont get? obviously there is
For double op amp is almost standard - pin #4 is ground or minus and #8 is +, the easiest way to find out where you connect the battery
ted:
Double check your drawing - op amp is in strange configuration
I did not notice that the op amp is upside down.
Correction
IN - to control laser beam
IN - photodiode modulation signal
Signal Out - from photodiode
Red + voltage supply
Black - voltage supply
