Well it was bound to happen. First decent weather but a few clouds and I dumped about one shot out of each string. Not enough to make it a wasted trip, but enough to make me go back and rethink things a bit.
CED uses an infrared sensor. Both indoor, and outdoor, measurements can actually benefit and improve from using a steady, reliable infrared source. Take a look at the link.

I'm waiting on my LED's at this point. They ran me a total of $6.50 for fifty of them. Perspex is a bit pricey and hard to come by where I live so I'm either going to use plexiglass or Lexan. The latter is still a bit high but much easier to work with.
Not all infrared LED's are created equal. 940nm is a requirement. The angle of divergence needs to at least be 20 degrees. The current ratings can vary a little so that means you might need to adjust the limiting resistors just a bit as well.
If there's any interest in this I'll post the rest of the details as mine gets closer to completion.
