I know ... "wrong answers only"... buuuuut... Home surveillance system to keep an eye on those sketch-ass neighbors. Build a camera obscura in the linen closet with your daughter.
Dave had them mounted to his cubicle walls. They allowed him to check the time on the clock on the wall without having to stand up. I already have four cameras. They are there specifically for the sketch-ass neighbor kid. The sketch-ass neighbor kid and his sketch-ass parents and grandparents were specifically made aware of the cameras when they were put in, and agreed they were a good idea. They have asked me "hey can you check who broke into my car this morning around 2am" and I'm like "here's the car, here's the guys getting out, but I don't actually have it pointed at your house". The sketch-ass neighbor kid is being recruited heavily by the Mormons. they show up twice a week to play basketball with him, then pick him up for and drop him off from church. I am honestly hopeful it accomplishes something.
