Answer
Lovely guess but no. This one has more pins, the integrated circuit is more complicated and many people don't have one at home.
Ah...
try 2
optical mouse sensor? might have the right pin count if it's the primary ic
If I'm wrong, I'm out of ideas, my house is far from a normal house, so my reference points are wrong.
Congratulations!
Thanks for using the spoiler tag. It’s working now.
And yes, I took into account that electronic nerds’ houses are different from most others.
The story
My Genius optical mouse was tracking poorly, even on patterned surfaces and mouse mats. I cleaned the lens and that didn't help. So I used a knife to open the chip, which is a pinhole camera with a die that integrates the sensor, a basic image processing system, button, wheel and LED controller and a USB (or maybe also PS/2) interface. I cleaned the chip with alcohol (mainly to remove the dust that had landed on it while it was open) and reassembled the mouse to find that it made no effect on ots functionality. I ultimately found out that the focus distance was off and I fixed it by removing the rubber pads at the bottom.
The chip appears to have no alphanumerical marking.
Full picture of the PCB with this chip – it is slightly damaged because I needed to scrape off parts of it to allow the cover to come off; I also did this because I thought of readjusting the focus by slightly lowering the chip (by bending its legs).
Pringles?
Answer + hint
Despite their fame, if you are reading this, you are more likely to have this kind of chip in your house than Pringles.
Pringles
No cap
Thermostat
No.
Answer
A thermostat chip uses a big transistor to control a relay, and is usually integrated with a touch/button and display driver, and it can be inside a conventional package. The thermistor is usually a discrete component created with different technology and away from heat-dissipating components.
However, your idea that it’s a sensor that needs to interact with the outside world in a special way is not entirely incorrect.
SIM?
Answer
That’s not a 14-pin chip. The device is apparently thicker, and it continues to function now that I reassembled it.
Bank card.
I'm just doing this to be noncompliant with your silly attempt at rulesetting.
Sorry for the inconvenience, I’m just trying to help people find hints in comments without someone ruining their experience by accidentally revealing the answer without a spoiler tag. This will keep the game fun even after someone guesses correctly.
Okay, I’ll drop the rule but I hope the correct guessser will retroactively do it anyway.
It’s not a bank card for the same reason it’s not a SIM (form factor)
