Odd electronic device identification/ HELP

[essanym]

Ok I am going to reach out to all the electronic guys for some help.

My stepson had an odd device delivered to our house and I am trying to figure out what it may be. He is not the most honest person and has a severe meth habit so I feel it may have some nefarious use. It is 3 parts. A battery, main body and it looks like an antennae. The main body has 2 buttons One large red and a small white one.


Any help would be appreciated. With this kids track record I am afraid of what it might be.

My first thought is bug detector (hidden wireless cameras or microphones).  Would your stepson think he's being spied upon because of his history with drug abuse?

Could you post more pictures from pretty much every angle and closeups so any text can be read?  There's a bit of glare on the right side of the device in the photo that would be good to avoid.  Also something for scale would be helpful.  I was able to make out what I believe is Huahong.  They are a semiconductor company.  I don't know if just the part inside was made by them or the whole thing.

I found what looks like the exact one.

Huh. TIL. Wonder if you can use the beam former of a microwave to target it and use it to annoy the neighbors.

It's called a magnetron... probably not unless you could waveguide it into a directional antenna.  Magnetrons produce fairly scattered waves.  I used to work with microwave transmitters and receivers so I speak with experience on this.  Also, were you able to actually do this, it would possibly hurt your neighbors, not just annoy them.

Maybe hurt was the wrong word. I've been microwaved before; it was very quick and didn't exactly hurt me, but I definitely felt it. For me, I felt it in my eyes since it was aimed at my head. The feeling was very indescribable... it felt like getting microwaved in the face. Anyway, if you wanted to mess with your neighbors, you could. It might not physically hurt them but it would be assault. I recommend not doing that.
