This sounds cool, do you have a more detailed write-up?

This article inspired me to build an exploded view of a mechanical watch movement in real-life (2025): https://fellerts.no/projects/epoch.html

I'm reminded by this short story posted to HN a couple months ago: https://nearzero.software/p/warranty-void-if-regenerated The discussion is interesting as many people didn't catch that it was mostly written

Jam a stick in the ground aligned with the earth's axis and take your bearing from the shadow's direction. Then follow GP's instructions. Never mind that we've reinvented the sundial...

CTRL + W usually deletes everything until the previous whitespace, so it would delete the whole '/var/log/nginx/' string in OP's example. Alt + backspace usually deletes until it encounters a non-alphanume

I’m surprised that they chose to add a bunch of components to feed the AC line frequency to the microcontroller instead of just using a 32.768 kHz crystal. A single crystal oscillator seems like both the cheaper and more accurate optio

I think this package does exactly what you need: https://pkg.go.dev/github.com/google/gopacket/routing . Works on my machine (error handling left to the reader) router, _ := routing.New() iface, _, _

That has nothing to do with the UI framework. The X11 dependency comes as part of the clipboard integration (which I'd argue should be optional or even removed). Still, I wouldn't call it modern if Wayland is outright not supporte

Cool project. Tip: acetone will readily dissolve the plastic parts of the card leaving the antenna(s) and chip intact. I believe a few other people have made drop-in PCBs with NFC antennas. Here’s one: https://n-o-d-e.net/da

The peak is a handful of requests per second. If you have a static site, the cheapest Hetzner tier handles it just fine.

Most services just include cleaning and relubrication. Parts don’t wear out that quickly. Most watches from before the quartz crisis (pre ‘70s) used standard off-the-shelf Swiss movements for which spare parts are still readily available. I

My drawer is already full of radium dials. I'm not sure adding nanoparticles to the mix is a very good idea. I've never heard of index matching fluids! Will have to read up on this.

I tried, but they're very difficult to cast. Epoxy resin is also very brittle and difficult to cut neat and square. A jagged edge does not bond very well to a smooth surface.

The minute hand is set to 43-ish minutes past the hour while the hour hand is showing 15-ish minutes past noon/midnight. If you’re used to reading analog watches it’s jarring.

Watch a few hours of watch repair on YouTube. If you're still intrigued, I highly recommend Mark Lovick's course over at https://www.watchfix.com/ . You'll learn all you need to know about tools, lubricants an

It is remarkable indeed! When not ruining watches with resin I enjoy servicing them, and I'm planning to learn how chronographs work next. The ST19 movement is on its way now, another very reasonably priced, reliable and fully mechanic

I never gave that any serious thought. What additives would do that, do you think? Edit: A quick search reveals that there is quite a lot of prior art from the optical community. Darn, maybe I'm not done here.

Well, if Bartosz doesn't reach out (I offered to send it to him), I'll consider sending it to Adam. My favorite builds of his are boxes that reflect their contents, and I'd love to see what he'd consider for something li

Thank you! That video somehow slipped by my feed, but I'll make sure to check it out. I'd imagine Adam getting a kick out of my resin project, but I don't think he hangs out on HN.

Never tried, because fluorocarbon's index of refraction (1.42-ish) is further from epoxy resin (1.50-1.57) than nylon (1.53). It does make sense that fluorocarbon has replaced nylon because it's going to be less visible in water (

I suspect you're right, but knowing myself I'd quickly get sick of sanding (6 faces with 5-6 different kinds of sandpaper), and I'd want an orbital sander. Then I'm pretty sure you want to polish the surfaces: lots of el

I tried that. Refraction makes it hard to understand what you're even looking at. https://fellerts.no/img/epoch/first-cast.jpg

Yep, nylon and epoxy resin have similar indices of refraction, but it's not perfect. I tried casting thin rods out of epoxy to replace the nylon but failed to achieve a good result.

Modern epoxies often claim to be UV stabilized, and as far as I can tell, this is a relatively recent advancement. For reference, I used Entropy CCR (slow cure) for the final model: https://entropyresins.com/product/ccr

You just clarified something I’ve unknowingly wondered about for years! Hardware stores here sell duct tape as you describe it, but it’s commonly referred to as «gaffer tape» in my native tongue (Norwegian: gaffateip). I’ve never come acros

Huh, that sounds very reasonable, and it's the first time I've heard it mentioned. Why isn't this more wide-spread?

I'd expect 911 to redirect to one of the emergency services in most/all European countries, no?
