If you have to constantly get in there to add more circuits, you might want to hang a painting or make a magnetic closed door that provides access. The second I took the time to do a nice repair the way you did is the minute I need to cut another hole. (I don't know if my comment is responsive, so please forgive me).
Please post your street address and zip code. I'll be right over!
You write how people think. I love it. Thank you, and keep making instructables!!!
Just LOVE this idea. So many non-functioning tubes are out there. People throw them out or give them away. And I hate to see them in the trash. Well done.

It does matter which wire is which. You want the switch to control the hot not the neutral. Otherwise the entire circuit is electrified and waiting for a completion, which could be a person if they are not careful. Which wire matters so much that new plugs all have a thicker side for the neutral to keep the polarity correct.
Do you find the weight to be heavy enough? I don't know what a pole barn nail weighs. Most of the bo shuriken I've used from Japan are surprisingly heavier than you might imagine. Of course, those might have been for dealing with different armor / clothing / distances than you may need for these.
