Very cool battery recycling project, I hope it works out as expected!

The audio is very quiet, it’s probably a microphone or post processing issue.

Castropod is cool, maybe you can try to figure out why it doesn’t properly federate with Lemmy and file some issues on both sides?

Those landing-legs that would be required add a lot of extra weight and in case of the Falcon 9 are a common mode of failure.

Pcie slots also allow adding more nvme ssd drives, although sadly most mainboards do not support pcie bifurcation, so you will be limited to a single nvme ssd per slot.

Up to RPi4 the power efficiency was a lot better, but performance wise you really struggled due to lack of options to connect faster storage. With the RPi5 becoming more power hungry (but also more performant) it is less clear cut, and price wise a refurbished x86 pc isn’t really more expensive either.

All in all I would say the benefits of using standard x86 outweigh the slightly higher power use these days. RPis are still good if you need the specific hardware GPIO etc. that is has though. But for self-hosting go for x86 and be mindful of peak loads (these CPUs become much more power hungry on higher clock-speeds, especially turbo-boost).

Yes that is afaik possible via https://fediseer.com/

That’s partially what https://fediseer.com/ does.

The same dev also made a CSAM scanning tool based on AI image recognition.

Look of a refurbished thinclient with a 6th or 7th gen Intel CPU with the “T” at the end (for example i5 6500T). Those are basically power optimized mobile CPUs for desktop PCs. Those are currently best value for money IMHO.

Alternatively use an old laptop, which is great for beginners, but storage extension will be very limited.

I think if the mirrors are used to boost the solar panel during times of the day/year when the sun angle is not optimal, it shouldn’t be an issue.

Prions are way too large to pass the reverse-osmois membranes.

If all you want is Nextcloud, you are probably better off getting a managed service like this: https://www.hetzner.com/storage/storage-share/

Like in Italy, right? /s

It is all in the article 🙄

The GM Energy PowerBanks are available in two separate battery capacities—10.6 kWh and 17.7 kWh—

Thanks to its modular design, two higher-capacity PowerBanks can be combined to offer 35.4kWh of stationary storage. According to GM Energy, that’s enough to power the average American home for up to 20 hours.

It’s just an easy to setup XMPP server, so you get full federation out of the box.

It would be ok, but a bit lonely, no?

Better look into Snikket.

Not so much to post about. It’s what you could call a slightly more advanced homelab, mostly using second hand hardware.

You can always look for a 12V car adapter charger for your laptop. For older 19V input ones (or similar) they are quite cheap and not that inefficient.

Modern laptops with USB-C power-delivery complicate things a bit as they use variable voltage and thus you need a special charger.

The description for the picture says they are connected to big burried concrete blocks, so likely the house is gone before these straps get loose.

Yes, sorry for that, see my other top level comment on that.
