Looks like it was a key fob of sorts, now less the buttons. Now it looks like a small circuit board with a blinking LED. You can put the batteries back in and short where the buttons made contact and see if the blinking changes.

I have no idea where any of the buttons (if there were buttons for this device) would have made contact. Could you please explain? I am a novice. Thanks a lot.

 

Those wiggly copper places are button pads. The U1 black blob is an IC.
Shorting the wiggles together is the same as closing the switch.

 

Question: When people have small circuit boards like this made, do they typically put numbers or letters on it to correlate to the device it is part of?? I'm wondering if this has anything to do with that rocket program that came up when I typed in the "STR-03A" in google.

 

Generally no since most of the times small boards like those are part of bigger main circuit and all the "codes" are on the schematics which show what is connected to what and what it does.

Thanks for the explanation. I appreciate it. Does this type of circuit look familiar?

The two squiggly areas are only about 1mm apart from each other and the rectangular thing between them is what was blinking like a powerful red LED.

No. It's the rain sensor and indicator board for my automatic umbrella.

 

The white block thingy is SMD LED.And squiggly areas are for conductive rubber buttons.

LOL re: Umbrella

 

So,.....could this be some sort of transmitter?

 

No,it doesn't have antenna.

 

OR,...is it part of a transmitter?

No,it doesn't have antenna.

ok,...was wondering if my wife is tracking me....LOL

 

Hopefully a suicide bomber lost his detonator!
Max.

 

Had any kids in the back of the car recently? Could be something from a children's toy?

So you have been a nasty boy?

 

Oh come on! April Fools Day was 4 months ago. "I found a broken part of something that would fit in a key fob and it blinks. Is this part of the International Space Station?"

Send it to the NSA. They seem to have time to investigate every person and every thing in the country.

noooo,......I am happily married

Stay that way

No kidding, right?! re: NSA investigating everyone and everything ,....I hearya

 

Thanks guys. I guess I will just throw it out....

Or give it to a kid... See post #32.
