Well, this is probably going to be a letdown...

...but it's a light bulb. Yup, an ordinary Sylvania 200w study bulb in my desk lamp. In the past this lamp has caused interferance with SOME learning remotes, but the ProntoPro NG is the first remote to actually attempt to capture that IR output as a valid code.

I had accidentally hit the "learn" button in PPENG before I was ready with the other remote, and was surprised when instead of the normal BZZZZZ of failure it beeped merrily. Wha-?

At any rate, the first non-repeating code was done through PPENG, and the repeating code was captured directly on the remote. It's all very consistant on what it captures.
