WiFi Time

I see `mitxela`, I click. This guy has been making such absolutely beautiful, skillfull, stunning, technical stuff.

I'd argue that is this post does not go into the 'beautiful' category, but nice technical read nonetheless.

I'd kill if we could just put an esp32 in a cheap alarm clock already to do autosetting. It's absurd I walked into my local big box retailers and nobody offers 'self-setting' anymore in person, and the closest thing you can get is a 'we set it in the factory and hope the battery we put in it stays good for a few years' now.

Good writeup and solid presentation of wifi timing experiments.

With his typical product-ready development and polished descriptions, I'm glad there are also some unfinished ideas in his drawer. (my imposter syndrome)

Article fails to mention things like hardware time stamping, interleaved NTP, and PTP.

Wow, first time I’ve seen this site, what a great thing to find.

> But more importantly, what I really should have done was just stick a TCXO on the board. Even without disciplining it, a TCXO will be within a few ppm out of the box. With that we could have simply polled, say, every five minutes and not bothered with anything else.

For the record, an entry level compensated rubidium oscilator is $5 from Aliexpress.

> This 8 channel, 24MHz USB logic analyser cost about £5, and they had the audacity to write "Saleae" on it, along with some delightful Comic Sans.

Devious, lol. My first thought was that it looked like Salae ca. 1990, but didn't think the company was that old.

This is a good writeup for wifi timing, first time I see this site.
