Wow. I'm impressed.
I just learned that you can check your remote controls IR output
using a digital camera.

You just point your remote control at the digital camera such as a
standard webcam or a standard cell phone camera and push the button.
It shows up on mine as a white light like an led light when looking
at the image on my viewer screen, yet when I point the remote at my
eyeball, I see nothing.



And then you look in the end of your fiber optic cable with your remaining good
eye.
