Hello everyone !

I'm seeding/cross-post this in 3 communities because I think I will get better answers in each respective one (Hardware, coding, electronics).

As the title say I'm want to learn to build from the ground up those cheap solar led/optic fiber lightning, here some images to get what I mean:

They come in bundles but after awhile they just die out without repair ability which kinda sucks and because they are cheap my mum keeps buying them... So, I would like to build ones I'm able to repair and customize :). However I have absolutely NO idea where to begin and what exactly I'm searching for... I'm lacking the skills and knowledge on the 3 fronts !

• What hardware I'm looking for ?
• What kind of electronics ?

Merged on Friday for the nearly-over Linux 6.15 merge window were the RISC-V CPU architecture updates for this next kernel release.

RISC-V with Linux 6.15 brings build improvements thanks to a re-architecting of the Kconfig build system options around RISC-V for selecting sub-architecture features.

For the Linux 6.15 kernel with RISC-V there is also support for building relocatable non-MMU kernels, support for huge PFNMAPS to improve TLB utilization, support for runtime constants, new RISC-V instructions supported, and a variety of fixes.

I've just had a 2nd USB3 SATA enclosure go bad. I can't remember what the first one was. This one is an Orico MS400U3. It was plugged into a Linux box with one drive and the drive started reporting strange errors so I removed the drive and connected it direct to SATA and it's working fine - after fsck fixed the errors on it. I thought maybe the USB port on the Linux box might be bad so I plugged the Orico into a Windows PC with a known good 1TB drive in it (a different drive than originally gave errors) - Windows sees the drive as 115PB and won't let me format it.

Is there any explanation for this other than the controller board in the enclosure somehow failing?

I'm thinking of going for this StarTech one next. Any other suggestions?

Would there be an interest with consolidating with the !hardware@lemmy.world community?

This one has more subs, but a lot less engagement and it seems the mod for this community deleted their account?

Hi,

I'm looking a way to make or buy an intercom system between room in the same house. That works more or less like a Walkie-talkie but wired on the local LAN .

With the following "requirements"

• only voice
• push to talk ( do not need to dial )
• broadcast the voice too all receiver
• AC-powered
• work on the local Lan (Ethernet)

If you know any device that does that or a clever way to DIY or even an android app (LAN only)
\ I'm all ears. Thanks
