Seems like nextcloud is the weak link, can you access them another way? Through a network share?
- Comment on Recommendation: Affordable soldering station for SMD work 1 month ago:
Have you looked at the pinecil? Its cheap and has very good reviews. The hakko fx-888d is a classic option for a reason too. If you’re doing SMD work, consider getting a hot air station over an expensive soldering station

Yup that’s exactly correct

They have a lot of products, including other fans and thermostats. I’ve had their media cabinet fans running 24/7 for 4-5 years now with no problems. Highly recommend it.
Otherwise you could use something like this and a standard 12v power adapter tindie.com/…/dc-12v-four-wire-thermostat-pwm-pc-c…
- Comment on Server for a boat 4 months ago:
You’ve gotten a lot of good answers, so I’m going to do some out of the box thinking - maybe it will spark a few ideas.
Goal:
- self hosted server on boat
Issues:
- size
- power
- corrosion
So if I were going to do this myself, I’d start with a pelican or other similar watertight container. We don’t want the equipment getting wet, and we don’t want it exposed to the salty air.
I’d probably pick a usff computer, like a dell 9020 or maybe a framework motherboard. To get the storage, I’d get one of these to add multiple sata ports to the computer. Then its a matter of getting a bunch of ssds and powering them. I think the 12v goal is going to be too restrictive, most laptops need 19v to charge, so I’d just bite the bullet and get an inverter. If you’re really tight on power you could go with a pi, but the framework motherboard/usff both use mobile processors, and shouldn’t draw too much while idle.
Any wires that pass though to the case should be made through waterproof bulkheads.
Personally I’d nix the HDMI out requirement. One more port to keep track of and it complicates the self hosting. If you want it for media streaming to a TV then I’d recommend a roku and just run a jellyfin server on the computer. If you want it for server debugging I wouldn’t bother running it out of the case.
The last thing I’d do is figure out cooling. For this I’d probably create some sort of closed loop heat exchanger from the case to either the outside air or the lake/ocean itself. This could be as simple as a pump running water through two radiators, one in the case and the other outside or just dumped overboard. If you know your power usage ahead of time you might be able to get away with a peltier element, dumping the heat outside the case.
I’d probably put this all on its own power system, get a solar panel, battery, inverter, etc. It could even get topped off by the boat’s system if it needs extra juice.
Also whatever you do, I’d figure out a way to ensure you’re giving your system a clean and steady 12v.
- Comment on current best HDD-model choice 4 months ago:
“The cause is a new SATA specification which includes the ability to disable power to the hard disk. When you look at the SATA power connection on the back of your hard drive, there are 15 pins that make contact with your power supply. It’s the third pin that delivers a 3.3V signal that disables the drive. What we need to do is prevent that third pin from making contact with the power cable.”
Some hotswap harddrive bays use this feature, definitely more common in enterprise scenarios or in USB HDD enclosures.

I’ve always liked the ultrastar line. Used to be made by HGST and then WD bought them. I’m using specifically the HC530 14tb. The line has a long history of being very reliable enterprise drives.
I’ve bought mine from both goharddrive and serverpartsdeals. Both are reliable resellers of used storage. They’ll warranty the drives for 2 or 5 years depending on which you to with. Prices are ~$130-$150.
Be aware you might need to do the electrical tape over some of the power pins hacks depending on your setup.
Ps. One of the listings for the HC530 on goharddrive or serverpartdeals is incorrectly labels as HC520. Just pay close attention.
- Comment on [Troubleshooting] Cannot fix a clogging issue. 7 months ago:
What printer and nozzles are you using?
Did you damage the thermistor or the heater cartridge during the first nozzle swap? Could be that damage is preventing it from getting/staying at the correct temperature.
Did you double check the slicer settings are correct?
- Comment on isopods are friends 7 months ago:
Yeah, my Lemmy client timed out twice trying to upload the photo. Then failed again when I trued using a link. Each time I refreshed it and didn’t see a comment, so I figured might as well try again. I noticed the multiple comments but it looks like my client just silently fails when deleting them. I figured it was funny so I didn’t try too hard to delete them (ツ)

- Comment on Tesla's Cybertruck may not be so stainless after all 9 months ago:
Theres no such thing as “real stainless”. Stainless steel 304 is corrosion resistant, it’s the cheapest and most common. 316 is better at corrosion resistance and is “marine grade” since it will hold up better to salt water. 316L is some of the best at resisting corrosion, it’s more expensive than 304 and is used in lab and surgical equipment. There are a lot of other types, like 309 for higher heat applications, etc.
Cybertruck is probably made from 304.
My company is exploring making parts out of titanium because even 316L isn’t corrosion resistant enough for our needs.
Definately not supprised that cybertrucks are having this issue. Especially with road salt in the winter. I’m sure the engineers at Tesla saw this coming too.

You’re comparing a microcontroller to a purpose built device. Its apples and oranges.
