Bought at an auction. Well actually given to me by the previous owner since there was no bid on it. A mystery blackbox. It features a red LED, a switch with 3 positions, an earphone socket and has room for a 9V battery.
Didn't try to connect a 9V battery yet. I really don't know what to expect. Should I connect an earphone, or is the socket for an antenna of some sort?
Anyone has any idea about this?
Update 7-March-2023
There was a question in the comments about the text on the solder side. It shows HB WEERT by RJ.
4 comments:
One IC is an audio amplifier, the other a 4 x NOR gates. Can be used in many functions like trigger or delay. As there is a microphone, maybe some sort of sound detector that triggers another "something".
Clap trigger to turn on the lights or something like that. Voice detector to start a tape recorder. Or whatever might be convenient.
And what is written on the other side of the board?
Seems there is something written there.

Hello Kees, you're right something is written on the other side. Will update the post this evening with a photo from the solder side. Hopefully someone will recognize this printboard.

Looks like a warp-core multiblock structure, responsible for providing the fuel input for the starship (as well as moving it around). Dilithium crystals can be put inline for improved flow stability.
Have fun! :-)

I think you have found the Internet!

Good luck on your discovery!
