We don’t understand what this home-made electronic doohickey is, even though you speak quite glibly about it, and since it is an Improved Electronic Device by our evaluation, and that sounds something that could blow up, we will not allow you to take it on the plane. If you buy one off the shelf, though, and have it in the original box, it must be okay, because a box is much more trustworthy than a passenger, so you can board now.”
