  • With LEDs in general the power supply is usually what makes a good one. Bean counters love to save money there because you can design a supply with very few parts, if you add a few more you can have a good supply. A better quality supply will have protection for itself and the lights. LEDs really like to run at their rated voltage, and they hate power spikes.

    For lights used outside the IP rating (how water resistant it is) usually needs to be taken with a few grains of salt.

    If I wanted something permanent-ish I would talk to people that install it professionally.

    While I have done Christmas lighting, I have never done Christmas light fixtures themselves. I do a lot of outdoor lighting for work. For my own personal stuff at home I always make my own power supplies.


  • That’s some kind of communist talk. In the Land of the Free you are your own man. No nanny state telling you what to do. You have options. You can be rich, you can put all your money into a scam bank, which is de facto sanctioned, (and die when they do a rug pull because you no longer have money for life saving, much less preventative care), or you can die. But this was your choice, and you can have a huge truck (N.B. the bank actually owns the truck, but in 5 years you’ll have it paid off).

    In reality I left the US years ago and don’t miss it, I do fear for friends though.




  • You can harvest the transformers for a couple junk microwaves to make an arc welder.

    If you aren’t experienced then pretty much all power supplies, battery backups, and motors should be left to someone else.

    I saw someone lose a finger (later reattached) to a washing machine with a jammed tub. It was plugged in and on when they reached underneath it and yanked the belt, their sleeve ducked their hand into the drive wheel.

    That said, if it fits your personality it can be both fun and satisfying to learn how to fix stuff. I try to teach anyone who’s interested and asks. Except LG washing machines, those things can fuck right off.
