I put this together by following the instructions. The instructions were clear and easy to follow,
and the idea is great.
As for the device, it generally works. However, I had a snafu where
the devices lost their connection during the show, causing a failure. So I would suggest coming up
with a failsafe test before you hand out the gimmicked board. If the connection is lost, you can
realize the problem and go to your backup option... say a peek or force or whatever.
