I was talking to my husband who has been traveling for work to an industrial site, and he sent me a picture that included a “permanent magnetic lifter”.
They look like this: https://www.magnet-sdm.com/wp-content/uploads/Permanent-magnetic-lifter.jpg
I had never heard of these and wondered how they worked - how is it possible to “turn off” a magnet without electricity??
I found a video where someone explains how this is possible: https://www.youtube.com/watch?v=PMma3OJUHhs
I got one of the smallest of these as a gift for my husband. This tiny thing is strong enough to lift 68kg. It’s strong enough to lift me!

This is an ingenious use of magnets! Thank you for sharing. I feel like I know something the general public doesn’t know, making me feel oddly powerful. hahaha
Neat. I use small versions of those at my job all the time. I’ve always wondered how those worked.
Headphones! I’ve recently learned that headphones are the most cost effective way to enjoy the audiophile experience. They even make headphone specific amplifiers. You could probably spend around 300 dollars on a good headphone set up that would cost you in the 1000’s speakers-wise.
And honestly I’m surprised it took me this long to realize just how awesome musoc sounds in them, all while not pissing off wife with speakers blaring in the basement.
Home Assistant, who knew home automation could be fun (except trying to integrate a nest thermostat who knew that would be the issue)
Man home assistant is such a rabbit hole. You start with automating a smart light then three years later your soldering your own custom ESP32 with a total organic volume sensor to automatically turn on the bathroom fan.
I like that idea, though most the fans are paired to lights here, very practical however!
In the two or so weeks I’ve had my HA live I’m almost certain its received more use from my family and I than nest has in a couple years. Frigate was very easy to get running and with some PoE cameras, no more missed events. Any pointers for doorbells and thermostats would be much appreciated
I learned how to set up and use HAProxy. I’m using it as a load balancer in front of my email service so I can update VMs without any downtime. It’s incredibly cool how versatile it is, but setting it up feels like nailing jello to a tree.
