My wife "organized" one of my drawers, and this thing came up. What on earth is THAT I asked. "It is just one of your thingeys" she replied.
It had no batteries in it, so I inserted some.. and nothing happened.
I has:
A speaker, a print (with a black-blob-chip on it), and.. some strange "sensor" or something? Strange little thing with wires on each side, to hold it together? And to mystify even more, that can be "sealed off".
Also, on the side it has some mounting-part, that had some old no-longer-stickey tape on it.
AND!! When I took the pictures, all the suden it started sounding like baabuubaabuu.. I shoke it, and it stopped, have not been able to reproduce!?!
Any one of you ever had such a.. thingey? Instructions for use?
Would you set your camera to auto-focus (half press teh button or whatever it takes) and point it at the thingey, then move it far away and then close to see if it chirps into life again?
Multiplicity Given that I was busily typing my response at the same time a voodoobot, I would defer to my learned colleague as an IR remote is a much simpler experiment than an auto-focus. I believe he’s thinking the same thing as me.
Thanks a lot, all solved now: I was subscribing to the Danish Dunald Duck magazine till about a year ago. It often came with little plastic gimmicks, and aparantly this one ended up in a drawer, never used or tested efore.
I now crack-opened it, and inside the little hole was a small LDR!
So I guess the deal must have been that you could glue it inside a closet or something, take out the pin from the hole, and when the closet was opened, the alarm went off.
What a crap piece of sh*t Likely to have ben made in a sweatshop, sorry kids.
