    High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.

    If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.

    Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.




  • +1 for ThirdReality. They’re a little pricey but I’ve generally had good luck with them.

    I’ve also had pretty good luck with cheap Matter-over-wifi bulbs. Pairing them can be a little finicky and needs to go through an Android or iOS process, but after pairing you can block Internet access for them and they work great local-only.

    There’s a bug in some wifi matter bulbs where they crash, especially when going from off to a desired brightness/color state (as in, “light on” works but “light to 50%, 3000K” will crash the bulb).

    Not a historian, but folks on The Internet have characterized the Soviet program as a series of milestones, with the US program a series of stepping stones in support of a single goal.

    This makes sense with the cartoon, where the Soviets were first in basically everything except walking on the moon.

    Not sure how much merit it has, but it’s kinda interesting.







  • Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.

    My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.

    It’s a fun exercise, not sure I implemented it in a smart way, but it works :)
