With concerns to computers or anything that has a hard drive: no.
Hard drives physically spin, so when it is writing or reading data and is interrupted, that means that, that spin motion was just interrupted which causes data corruption.
Now my knowledge of t.v’s isn’t that good, but most t.v’s that i have encountered don’t have a shut down sequence since they can be turned off with the push of a button without issue, so they should be able to survive sudden power losses.
After all this i still feel it is good practice to shut down devices before any known power losses like loadshedding, as i have experienced a fridge, and a wifi extender fail due to what we believe to be loadshedding, however this could also have been due to old age so it could be a giant coincidence.
Turning off plugs after the power is out is a very good idea as sudden power surges is never a good thing, no harm in waiting 5 to 10 minutes after power comes back on to plug everything back in or power everything on, in case of the power going off again.
I wonder if there are switches that trip when a power outage happens. That would be excellent for saving your electronics or just about anything that runs on the magic smoke
My battery backup for my ONT and Router barely last a half hour nowadays and in search of a replacement. It doesn’t have to be anything fancy or big, just to last the 2 hour stint.
All the battery backup solutions I’m finding seem to be aimed at mobile devices and only have USB support. Can anyone make any representations?
You can get 18650’s off the shelf. The real question is are the 6 it comes with inside wrapped in blue plastic with a charging circuit inside… Best case scenario, you might just need something like this:
(3RD option, 3S2P)
I know you said yours isn’t the same model, but if it has screws and looks easy to open… If you’re comfortable with that.
Weirdly, my pc just crashed whilst gaming last night, a beautiful black screen. I thought it was the HDMI cable at first, but replaced it no go. Ended up letting the pc rest for a bit and turned it on again, all seems well. I have a gut feeling its a win 11 issue
Just not sure what to do
Check the windows logs, not sure if it is the same in win 11 but look for Event Viewer and check out the Windows logs - system section. Look for any errors around the time it happened.
Finally got my new MacBook Pro 16-inch M1 and now wondering, should I make use of the migration assistant, and if so, does it give you the option of what to take over?
I don’t want to transfer all or some of the kak from the old.
So seeing as I don’t have the capital to fund an inverter or solar, in an attempt to circumvent the load-shedding stints, I have this idea: find an old 2KVA UPS that someone is selling or throwing out (due to batteries being degraded), and connecting up two 590 lead-acid car batteries in series. Disconnect the buzzer to avoid the constant beeping.
The output should be enough to power most electronics for at least 4-hours, and probably longer. Of course, I am not trying to power my entire house, just some electronics such as TV, routers, consoles, etc.
I’d be afraid of smoking the UPS, they’re expecting two or four 7 or 9AH batteries usually. To throw 80-100AH at it might be too much for it to handle (but… amps are pulled, so maybe it won’t be an issue…) Apparently the transformers have to be able to handle it. There might be more to this than meets the eye. (hue hue hue)
The other thing is how long would it take for those batteries to recharge? Inverters usually charge at 10 or 20A. A UPS probably more like 2A, so it might take a whole day or two to fully charge depleted batteries…
I would suggest looking at a 2kva inverter made for 100AH batteries rather than using a ups. As stated the ups system is designed on 9AH small units in series and parallel. Slow trickle charging which takes a long time sadly. They were never designed to run equipment for hours, rather minutes.
You can push this of course but batteries will not last.
You can also look at options where you can replace lead acid with new lithium based in place replaceable batteries. Longer lasting but the load is going to be a pain.
Depending on what you are planning to run, I would rather look at the gizzu or ecoflow power stations. Roughly 10k for a 600w system.
Ups sadly just isn’t meant for blackouts, unless you run a generator with it.
Hopefully there are a few electricians here who could provide more info. But short term plan to save money just ends up costing you more after 5 to 6 months.
I’m not an expert on this at all, but having supported all manner of systems for these blackouts I have seen any options and options are limited to your available budget. I always advise spending a bit more for a proper solution than spending more money to upkeep something that can’t handle it.
My younger brother is (eventually!) getting married next month and wants to set up a livestream of the ceremony for our and her family and friends overseas and out of town.
Thoughts on the best platform to use and the easiest approach to take? Especially if they’re going to use a mobile phone and app.
It’s going to be outdoors so they’ll probably use a data connection to connect to the internet. As an alternative to direct from a phone, they could possibly use a laptop linked digital camera for the filming but not much more than a static shot.
They don’t want it to be an open public thing - just visible to those with a link. They’re also a little concerned that some of the potential viewers don’t have FB or Discord accounts and some won’t know how to use Zoom or there won’t be enough time to stream it all on one of those meeting services.
From my brother, who works in film and has, like, an actual IMDB page:
He says his go to would be Youtube, where you can set it up as an unlisted video/stream, and thus you’ll get a link you only share with invitees. It might still leak out, although the odds are low, and most people that “find” the link won’t really care.
The alternative on Youtube is a “private” link, but this requires a Google/Youtube account, so you’re running into the same issues as with FB and DC.
The plus side is that with the described equipment, you’re not renting anything, so the whole setup can be tested beforehand. Like, today, even!
One last thing everyone forgets, is good sound. If the stream can’t hear the officiant, you might as well leave it!
All of this was translated (poorly) from Afrikaans Whatsapp messages, so apologies if I got some terminology wrong.
We recently joined a funeral service that was streamed over YouTube and the overall experience was great as an attendee. I believe you can make the stream and subsequent recording unlisted so that only people with the link will have access which keeps of out of the public eye. Just something to consider and sharing my thoughts and opinion.
