With a lack of the 38khz IR detectors until later this week I decided to implement this circuit that is online here.

Since my MCU needs 1.4V to detect high I am using a LM324N 4in1 Opamp
for Two IR eyes.
With the setup shown below It detects a hand at about 2 feet.
I messed around with different resistor values before settling on this temporary setup. Can anyone see any obvious improvements?
A little Youtube action!
