Boredom can do strange things - And internet searches go in unexpected directions

Recommended Posts

And now my warped mind is thinking "how about an analog version with hands driven by stepper motors"?

 

The bane of my life is that we have half a dozen quartz clocks all showing a different, but always incorrect, time.

I don't think I trust the humidity sensor (it's been in the bits box for longer than I care to remember), 34C is believable, but 95% RH? 

You might find a DHT22 sensor will provide more accurate humidity results. Also check your sampling rate is not too fast.

DH11 is what was "in stock", sampling every 30 seconds, could slow that down significantly with no detriment to usability.

The simple timing is losing about 2 seconds an hour without me doing any tweeking, probably not worth worrying about.

 

NTP sync. is on startup then every 2 hours, could easily stretch to once a day.

A version for those with a 16 * 2 display, I think the smaller numbers look better actually.

Oh, and the dual-shaft stepper motor for the analog version should arrive today 🙂

After a couple of months playing with the ESP-8266 and discovering that it can be programmed using the Arduino development system an update.

 

Who needs the Arduino and the clunky "AT" commands to the ESP?

 

The ESP is a powerful microcontroller in it's own right and the level converters (5V to 3.3V) for the serial Tx and Rx ports on the module are bi-directional, so with a little research we now have the Wife Clock Mk2.

 

Give it 5V and an internet connection and you're good to go. The 5V LCD data goes via the Tx and Rx pins.

youll  need  the special Thai adjustment tool  to correctly set everything.

Way back in the day when dinosaurs were still eggs, Crossy was still in his playpen gazing up at the wonder of the workings of the light switch and electronics was the new and exiting science, I remember constructing a Nixie clock.

 

In those days micro chips were the size of a matchbox and circuit boards were so big  you didn't need glasses and soldering was piece  of cake.

 

Amazing how rapidly things have progressed since those years, who would have thought.

 

For you youngsters this is what a Nixie clock look's like:-

If your interested in some retro look, software for Nixie desktop clock and Nixie clock screensavers can be found on the Internet.

The first calculator I ever used had a nixie tube display..

I appear to have built a fully working bells and whistles singing and dancing time warp whilst not even trying with fully integrated groundhog effect and being trapped alone in Swindon works with 100% accuracy but alas building it in reverse is proving impossible due to the quite common General effect 🤔

What about the Radio clocks? Don't they work in TH?

The ones that automatically synchronise with a Satellite or some other source?
