Yes, I agree. Damn... I guess I better just get some plastic as Harry suggests. That diffuser texture will surely be part of the video.

That a milk jug that you used as the diffuser? Recycling!
Steve Anderson wrote:Your problem with the Chinese-made module maybe one or both of two things. First, depending on the distance from the disc to the LED and detector, they may need angling in towards each other for better coverage and sensitivity - looking at the photo that may be difficult to achieve. A lot of these devices have a beam-width/sensitivity curve of only some +/-10 degrees.
Second is if the disc markings for this are printed (laser or ink-jet) rather than 'done in hardware' a lot of inks (black in this case I assume) are reflective at IR.
I hope this helps...
