It isn't exactly what I envisioned, but I don't want to fuss with it too much. As you can see in the POV shots, the lens of the camera can't be in the middle of the monitor. That's because the cabling keeps me from putting the monitor dead center. The monitor is also too thick to tuck back into the teleprompter far enough the center the lens top to bottom.
I could use right-angle cables to solve the first problem and raise the camera to solve the second (although then I have to be careful about getting the top of the picture frame in the shot). But the fact is that it works really well the way it is, and I was able to use only gear that I already had to make it work.
To be honest, I haven't actually used the teleprompter as a teleprompter all that often. Just lazy, I guess; it takes a lot of tweaking to get anything resembling a natural rhythm from the teleprompter. But now that I've repurposed the box, I can't imagine getting in front of the camera—when I don't have a crew—without it.
If you didn't read the blog post, or see the video, about the construction of the teleprompter, take a look here.
