I have trouble believing that you're pointing this out in good faith.

#133Related - we have an atomic Seiko wall clock expecting to have the time automatically adjusted by the WWVB LF atomic clock broadcast. Turns out, the signal is very weak where we now live. Manually setting the time on these atomic clocks is a HUGE pain (beware!). Turns out it's possible to emulate the atomic clock signal quite easily with a Raspberry Pi, or in my case I put together Arduino code that can emulate atomi…
I would be very careful of transmitting on the same frequency as WWVB. It is very likely illegal.
Quite possibly, however the range is stated in centimetres so practically it’s unlikely to be a concern.

#134On this topic. Do WiFi signals contain time (unencrypted)? If so why does my oven not pull time from the air and needs adjustment every 2 months? If not, why are APs not defacto time beacons for all sorts of non-smart appliances (and clocks)?
The gateway/router should be the time source. DHCP has an option to provide the time server (NTP) - option 42, and most decent devices or OSS/DIY router software (OpenWRT, opnSense) will support that as well as being the local time server.

#135So basically we just need a 1pps from a GPS chip to make the analog clocks accurate and use that to drive the motor. We set it once and it will be accurate for a long time.

Undermining the spirit of HN: By the time you’ve spent a few hours hacking away and bought any parts, that price is probably not too bad.
That's assuming you don't like hacking and would pay to not have to do it, which is generally not the case around here.
I disagree.
My most precious resource is free time. I never have anywhere near enough.
It is absolutely not worth $5 for me to spend another 15 minutes trying to find a cheaper price

#138What I really want is one of these powered by gps. The time already comes for free in the signal, and from your location you can derive the time zone. That way DST is accounted for automatically, but you don't have to set up and rely on wifi. This would be truly zero-config and always correct.
GPS isn't too hard, either. The receivers are inexpensive ($5-$10 for the kind of accuracy that's useful here) and it's not hard to parse the NMEA strings and PPS they output into a spooky-accurate internal clock. It only takes a few connections and an antenna to integrate GPS into an MCU like an ESP (or an SBC like a Raspberry Pi or a whatever). Like, really: The hardware is ridiculously easy. The only difficult par…
The actual difficult part is getting a GPS signal indoors with a cheap receiver, sadly.

What's the purpose of using an LLM to write a comment here?

There is an extension called HN Friends that allows to add information to a tooltip for users and shows a hint that there exists such information.
Use this as you like.

#140$3.88 ? Walmart.com uses dynamically variable pricing that includes geographic and user variance - my price is $5.92 https://www.walmart.com/ip/Mainstays-Basic-Indoor-8-78-Black...
User variance? Any evidence?
