Do I need a relay or something else entirely? (infosec.pub)
 

So I’ve been using an old repurposed tractor lamp as my bedside lamp. I wired it up to mains (EU 230V) with a well isolated alternative bulb and bulb holder (the original bulbs are impossible to find). This has all been grounded and done the best we could. Now comes the problem, we reused the original switch (as it looks good) which it turns out, does not really appreciate having to switch 230V instead of the 12V (or 24V?) it was designed for. I believe I can patch up the switch to work as designed, however I do want a better solution to switching the lamp on and off.

Do relays exist that provide their own low voltage power that I can hook up the switch to? There’s not a lot of space available in the lamp, so I was hoping for a compact, drop in solution.

Other ideas are welcome as wel. I’ve thought of converting everything to 12V, but that would mean finding a new bulb holder, and having a transformer to put somewhere.

Eh, we’ve done pretty well with transmitting power. So although I do agree that spreading the load is always better, it should not be compromising the costs. As putting it “everywhere” also comes with some downsides.

Well, we could also stop adding a certain percentage of biofuel to our cars. The land that we gain from that, if covered by solar panels, would produce enough energy to cover all our energy demand.

The fact is that pressure is force per unit of surface. So your car tires are holding in a lot more force than your bike tires, even though the pressure is lower.

I use AdGuard on iOS, but I expect uBlock to also work (for the web version of yt).

Aluminum is not a naturally occurring metal however, but I do get your point. Never knew we received so much already.

No starlink is bad. It’s currently deorbiting 1-2 satellites a day, which means half a ton of aluminum and other metals burnt up in the atmosphere. Current ambition mean they will need to start deorbiting 3-5 satellites per day.

We don’t know yet what ecological impact this will have. But I’m having a hard time accepting such wasteful energy and material consumption.

Opinions on best bang/buck for TV audio (infosec.pub)

I’ve recently moved and want to buy a tv and audio set up. TV is taken care of, however I am looking for better audio than stock TV speakers. I’m probably going to get an Apple TV and stay away from the “smart” features of the TV.

What would be the best price to performance audio solution?

I was looking at second hand AV receivers, but those are still quite pricy, and I will probably be satisfied with good quality L-R(-Center?) channels. I’m comfortable with jankier setups (more wires), but I am looking for better sound quality. So speakers, should I get older ones on the cheap (sub €100) or are newer speakers really worth their premium?

I’m curious what your setups are and based on experience what you would advise for.

Techcrunch reports that AI coding tools have "very negative" gross margins. In other words, they are losing money on every user. in c/technology@lemmy.world

Ed Ziltron has a good piece regarding whether the losses are “just another startup” or something more. I am very much leaning towards “burning money at an insane rate just to give the impression of growth”.

WHERE ARE MY PRECISION SCREWDRIVERS in c/lemmyshitpost@lemmy.world

In wood yes. But please keep them off my bike. You suddenly really start to enjoy the ball end of your Allen keys when working in tight spots and torx has none of that (and some brand are starting to use more and more torx on their models)

My QM portafilter was slowly vibrating off the support fork of my Eureka Mignion Specialita. So I did my first mod… (infosec.pub)

When grinding coffee the vibrations slowly caused the portafilter of my Quick Mill to drift off the (admittedly not great) support fork of my new Eureka Mignion Specialita. In the nook of plastic top holding part sits a screw, so I had the idea to bend a piece of copper wire and mount it under the screw. The piece (image below) hold the sides the of portafilter protrusion. This way it can’t turn away and I don’t have to keep an eye on it constantly.
