    Oh yes, I'm sorry I didn't install in on to it when taking the picture, This is the complete version of my circuit. I can only find this IR photo diode and had no luck looking for an infrared LED. Therefore I was using a red LED, hoping it can produce sufficient IR to make the circuit work. However, the result was when I have everything set up, the change in voltage across the LED is only a few mV, making the out come not visible at all. Do you have any suggestions in this situation?

    Hi! This isan awesome project! I tried to construct the circuit, however the 12v powersupply I was able to obtain is only capable of providing 229 mA of current, andthe indicator LED I found is very far from the quarter-amp requirement, whichresulted in not enough brightness to enable the feedback cycle even when Ichanged the voltage amplify ratio to 1/47 of the original. However, I was ableto measure the change of voltage around the LED and confirmed change in voltagewhen I moved a flash light in and out of the “view angle” of my pinhole camera. In this case, do you have anysuggestion to take a step further to complete this apparatus?
