Merlin rollerdoor (Australian garage door brand) stopped working, when investigating I found a bug had shorted itself across an IC (labeled HVS004).

Luckily Merlin sells the whole replacement unit for only $449AUD. Before I pull the trigger on that I was wondering if anyone here could advise me on my chances of success if I just replaced the burnt bit.

I’m happy with larger electronics but I’m struggling to even identify any fuses on the board to check.

I’m also unable to find a replacement IC online as the code on it seems to be associated with some kind of blue LED. (I also don’t know for sure if the IC needs to be programmed or if it is just standard)

The back of the board is fine, just thru-hole solder connections.

here are some more photos(new link, should work now), hopefully in good quality.

Thanks in advance

I spun up nextcloud to replace onedrive about a year ago. Everything was going well so I chose not to renew my onedrive subscription, this was exactly 6 months ago, I'd assume.

I got an email a few days ago reminding me that they would delete my data. I ignored it because obviously I had moved my data to nextcloud. not gonna trick me Mi¢ro$oft.

But yesterday I decided to have a quick look though and it turns out I didn't copy over everything, and certanly not my 5 years of camera roll backups.

I started a sync of everything last night and woke up in the morning to find that it had stopped at about 10gb out of 80gb. And now onedrive won't connect and if I try to log in to onedrive with that account via the web it just kicks me back to the microsoft portal.

I'm 99.5% sure there is nothing to be done and I'm not an overly sentimental person so if they are lost it won't break me. I have many important photos backed up in immich but just not everything.

But I just needed to ask in case someone knows where to find the M spot I can touch for magic file recovery.

Edit: turns out you can just pay them more money and they still had my stuff. thank you for joining me on the shortest support ticket of all time

I didn’t.

Trying to trouble shoot a cheaper wireless meat thermometer. It was working find when put away last year.

Now won't turn on or respond when put on charge.

The lithium pouch cell looks fine and reads 3.5v at the battery tabs. No voltage read on the output of the small circuit board attached to the pouch cell. A bit of googling has lead me to believe it is some kind of "battery protection circuit" or possibly a BMS or charge controller. I have found many similar ones but no exact match on AliExpress. It reads QLD-3036.

If anyone is familiar with those little boards can they let me know

If there would be any reason it would be stopping power getting from the battery to the main unit?

If there is some easy way to reset the board?

If the small board modifies the voltage of the battery at all and if not would it be ok to bypass the small board and supply dc to the main board where the red and black wires connect for testing purposes? I have a variable power supply and would have no issue with converting this unit to run connected to a power supply permanently.

And then I read about someone’s smart bed that got stuck in an upright position on heat mode because of the outage. Makes me feel like all that time sourcing devices that run locally was worth it.

Are we just digital preppers?

Edit: I get it, you aren't preppers, I'm sorry I said that.

From reading your comments I have gathered that you simply want to be ready (not prepared!) for when a free service becomes paid or they shut something down that you use or you simply don't like the idea of the gubbermint or the corporations being able to look though your data.

Many of you seem aware that your concerns are considered far fetched or like non issues by the average person.

well you are preppers, I'm sorry you had to find out this way.
