Hey, it actually worked and took less the a couple of min.

I have one, going to try and tape it off from the other components heat it up and see if that works.

Yes, The 5v regulator is the same and it is outputting 5.01v under load and 5.12v no load. Not sure why the first went bad but I’m guessing the POS 5v reg sent a spike on the 5v rail when it went bad and that damaged the TLV75733. The Teensy acts exactly the same connected to a USB unmounted from the board. It boots, runs for a min while the TLV heats up then the 3v3 drops and the Teensy crashes.

Do beeper services even exist anymore? I would think they all got displaced by cell phones long ago.

No beeper in this photo. Could be a piezoelectric disk hidden some where they are small and thin. what’s on the other side of the PCB? Also look stuck to the plastic, piezos are often stuck to the casing to use it as a sounding board.

Edit: not sure what the yellow thing, cap maybe, can you get a better picture of the text on it ?

yep, here is the DigiKey link

@jarrodsfarrell This is out of production but you can use this link to get the package size and form factor to search for a replacement.

I work in IT and users will get upset if you give them the “Please put in a ticket” line. So for the people that might grumble at this stance but there is good reasons for it in addition to not clogging up this community it’s good for QA. I’m new to Lemmy so not sure if the SAs and Devs frequent !lemmy_support@lemmy.ml but I suspect they do and driving support questions to a common spot will help analyze need for new features, UI changes, bug fixes, etc.

Just my 2 cents but I like your stance.
