IR Sensor for Arduino

Since I plan to use this really great IR library, I've built an IR sensor using an IR module I salvaged from a broken VCR. This module is very similar to a TSOP17.. module:


so I've used the circuit suggested in the TSOP17.. datasheet:


Testing the circuit on a (mini)breadboard it works well (here I'm using this microcontroller board and an LCD to show decoded codes):



The IR library is really good!

Here's the schema of a realization of this circuit on a stripboard:


And here is a realization of the IR sensor, ready to be plugged to the microcontroller board:
