Show HN: Clocksimulator.com – A minimalist, distraction-free analog clock

https://www.clocksimulator.com/
61•user_timo•2h ago
Hello all! Build clean, minimalistic analog clock webpage to Cloudflare Pages.

This is for (maybe): - kids to learn - for second monitor - old tabled on shelf - ..

Themes and screen wake lock buttons with auto-hide. Goal is to keep it as clean as possible.

This possible makes no sense, but for a domain of $10/y this is cheap site for me to keep and see how it lives on.

Comments

alcazar•2h ago
Kudos. It really is clean. And the domain name is easy to remember.

If I use any analog clock simulator in the future, it will be yours.

user_timo•2h ago
Thank you :)
user_timo•2h ago
It takes current time from client browser and shows it. No adjustments or alarms.
jdauriemma•1h ago
Better than 90% of the slop that gets ladled into the front page, bravo. The world needs more Clock Simulator-like projects.
user_timo•1h ago
Thank you very much!
Faaak•1h ago

user_timo•1h ago
Clock took some inspiration of our kitchen clock.
bayindirh•1h ago
Want to carry that on your wrist, or hang to your wall?

You're covered (down to the stalling second in some models): https://mondaine.com/

Daviey•58m ago
Something related to cultural appropriation, but it reminded me of Canary Wharf (London) clocks, https://canarywharf.com/artwork/konstantin-grcic-six-public-...
bayindirh•1h ago
Looks really neat. I used to use a very similar screensaver back in the day.

Kudos.

user_timo•1h ago
Thank you! Yes back in the day we used to have all kind a clocks as timesavers.
natpalmer1776•1h ago
This looks really clean, excellent job!
user_timo•1h ago
Thank you for the nice words :)
elteto•1h ago
Very clean and polished! I love how smooth the seconds hand move.

I work in an environment where we look at the time across many different timezones around the world. A couple of feature requests if you are ever in the mood:

  1. Make it possible to specify the timezone.
  2. Make it possible to create a grid of clocks, each with different timezones.
  3. Persist the grid/timezone state in the URL so links can be easily shared.
user_timo•1h ago
Thank you! Very good idea, I look forward to implement URL timezone parameters to get it on different zones without it affecting to UI in any way.
AustinDev•1h ago
Great feedback for the OP. I would also add, Can you make the text not selectable?
user_timo•1h ago
You can now select timezone with URL parameters in IANA timezones: ?tz=America/New_York ?tz=Europe/London ?tz=Asia/Tokyo
elteto•58m ago
Wonderful! Thanks for the quick turnaround.
user_timo•43m ago
Clock now also moves very slowly in screen, in dark mode it can reduce screen burn.
noman-land•1h ago
Very smooth. Is the code open source?
user_timo•1h ago
Thank you. Code can be viewed at https://github.com/timoheimonen/clocksimulator
noman-land•1m ago
Thanks! I was keen to find out how you prevented screen sleep and was interested to find out about wakeLock.
Julien_r2•1h ago
Seems to be simple enough (just plain JS not minimified, and CSS), that you can just look at the source view-source:https://www.clocksimulator.com/

Good ol' days spirit

lioeters•1h ago
I like it. Simple, well-designed, smooth. It's nice everything fits in a single HTML page with no external dependencies. The inline style and script is human readable, which is becoming rare these days.
user_timo•1h ago
I wanted this to be small and clean, open source and nothing to hide.
qwertfisch•1h ago
Can you set it to ticks instead of continuous running of the seconds clockhand That would be great. The vast majority of analog clocks have a ticking clockhand for the seconds, if any at all (can you make the seconds optional?).

The only clocks I know of with such a motor are station clocks, like the Swiss one mentioned already, or the German variant (same manufacturer). But these have a twist: the minute clockhand does not run continuously, but also ticks. The seconds are running a little bit faster until the clockhand is in the upper position, then waits for a signal from the main clock. Only then the minute clockhand jumps one minute and the seconds are starting again.

An example can be seen here: https://de.wikipedia.org/wiki/Bahnhofsuhr#Technik

user_timo•1h ago
Thank you for the feedback. I see if I add toggle to select tick/sliding.
frutiger•1h ago
Most mechanical watches unwind smoothly, ticks are typically due to a powered quartz crystal.
swader999•1h ago
I'm more of a fan of the smooth motion. Its mesmerizing.
user_timo•1h ago
there is now toggle button to select either way.
swills•15m ago
Same and also I consider it more accurate to sweep, but that's just me I guess, you hardly see it these days.
sirbranedamuj•1h ago
I appreciate the straightforwardness of this. If I could make one request, it would be to support more of a "tick" mode instead of the continuous second hand motion. It doesn't even have to actually make noises, I just like the visuals of the clock hand starting and stopping every second. I don't know if there's a more formal name for this in Clock World
user_timo•1h ago
Added ticking and liked it so much its default mode :)
cbm-vic-20•1h ago
If you're looking for more to add: ticking second hands have momentum. How about having the ticking hand go beyond the proper place by a degree, then snap back into proper position?
maratc•1h ago
You're literally describing the worst thing about the quartz watches. The best of them (aka most expensive) go to really great lengths to not have any momentum. Why would you want to have it when not needed?
maratc•1h ago
Here's a request to not have ticking :) Time is flowing constantly and seconds are a human invention.
qwertfisch•1h ago
The PTB (national metrology institute of Germany) provides a similar clock for decades. It is one of the few displaying the real time, not your computer’s time. The difference (if any) can be shown.

There is also a time announcement if needed.

https://uhr.ptb.de/

user_timo•32m ago
That looks nice!
nikolas_sapa•1h ago
wow bro. how did you even come up with the idea. I also like the fact that there is a toggle that you can switch if you want screen on. pretty smart
user_timo•1h ago
Listened my wife talk about her job, she works as preschool teacher and she has talked about clocks etc. Well then I thought that I could do minimal web page with analog lock, SURE clocksimulator.com domain cannot be free....
jannniii•1h ago
Very nice!!
user_timo•32m ago
Thank you :)
signalmasse•1h ago
Love the correct time in the favicon. Nice touch.
user_timo•1h ago
You found it!
kipdotcom•1h ago
May I suggest that we keep it as clean as it now, and maybe have something like the domain `/advanced` for those who want more features? (If OP has time to implement them)
user_timo•1h ago
Few toggles I approve on front page because of auto-hide. Good idea of /advanced for future things.

I built a digital clock for my neighbor with Alzheimer a few years ago. It was a web app with an analog clock and it would show Morning / Afternoon / Evening / Night on the side.

I felt quite proud of myself, since she often got confused about whether it was 6am or 6pm on her analog clocks at home. (Alzheimer's can bring a loss of the sense of time.)

But while she thought it was a great idea, every time I came back, she had turned off the dedicated tablet we set up for the purpose

I ended up just buying her an Alzheimer's clock — a 24 hour clock with pictures indicating the time of day, for $15 or so. That one stayed where we put it!

jzellis•1h ago
That was very kind of you - both to want to solve her problem and to admit that your solution you put effort into wasn't the best one for her.
user_timo•55m ago
Thank you for sharing this.
dbacar•1h ago
Excellent, maybe an addition for protection from display burn-in would be nice. I dont know. Congrats.
user_timo•1h ago
Burn-in is sure possible, I will look possibilities maybe move clock little bit etc. Thank you for you comment!
matthova•41m ago
Love how clean it looks.

Related, I made a clock with a moire pattern (10 years ago now) and still love coming back to it.

The hands all spin with css transitions and I remember there was a Safari bug where if I zoomed in, the rotation would reset itself

user_timo•39m ago
Wow that was a trip for my eyes, nice! Thank you for sharing.
xeor•28m ago
This is something I vibecoded to learn my kid the clock. I think this is a very good use of ai coding, stuff that is for visualization and temporary learning.

https://utforsk.github.io/clockeroo/

user_timo•24m ago
That was nice thing to do, did it help your kid to learn?
Implement7347•25m ago
Pretty cool idea, i wish it had that nostalgic ticking sound of seconds.
