Ask HN: What should I do with meet.hn? (Score: 150+ in 8 hours)

Link: https://readhacker.news/c/6jvMQ

Hey HN! A few weeks ago, meet.hn was released: (Show HN: Meet.hn – Meet the Hacker News community in your city - https://news.ycombinator.com/item?id=41539125)
We are now about 1700 hackers willing to meet each other in almost 700 locations worldwide.
Since then, some requested features and bug fixes have been implemented:
- locations are now searchable and not restricted to a simplistic city-country pair
- locations work with diacritics and diverse languages
- new socials: personal website, email, Mastodon, Discord, GitLab, Google Scholar, YouTube, etc.
- upon user request, I can now showcase your local meetups on your location listing, as it's done for Old Toronto: [1]
About actual meetings, I'm aware of around a dozen so far, but I think many more occurred.
Why am I writing this post?
About 80% of the ~1700 signups happened in the first 36 hours after launch.
As expected, signups dropped pretty quickly, and now it gains about one new user every other day.
I think a ton of global value (and local joy) can emerge from HN users meeting each other.
That's why I'm writing this post. To answer the question: how can we meet more? and how can meet.hn help?
What I thought about:
1. Implementing RSS for each location: helpful for RSS users only, and not that useful if there are no new registrations.
2. Email notification system: wide audience, but requires users to give their emails.
3. Turning meet.hn into some sort of an atproto [3] project, or at least leveraging it somehow. Might be more Bluesky centric (if we use labels, for example), but maybe not?
4. A bookmarklet which, once clicked when on a HN post, would insert a meet.hn logo next to all user names of users commenting there and registered on meet.hn
5. An HN "proxy website" which would copy HN in every way, but would add the meet.hn logo just like the bookmarklet described point 4 would do, but everywhere and automatically.
6. Create Telegram (or equivalent) channels for each location
But all of these ideas are unideal fixes. The lowest common denominator between everyone on HN... is HN.
Hence, meeting right from HN would be best. An MVP for this could be to have a "willing to meet" attribute with a boolean value (like the "showdead" or "noprocrast" attributes).
When enabled, an icon would be shown next to the user name in threads.
I talked to dang, and even if the idea of implementing something on HN is not out of the question, it is not on the roadmap yet.
Let's discuss all of this in the comments. Looking forward to hearing what you think.

Show HN: I designed an espresso machine and coffee grinder (Score: 154+ in 8 hours)

Link: https://readhacker.news/s/6ju2Y
Comments: https://readhacker.news/c/6ju2Y

It was a lot of work as a solo project but I hope you guys think it’s cool. When I say “we” in the website it’s only in the most royal sense possible. I also did all the photo/videography. I started out designing a single machine for personal use, but like many things it sort of spiraled out of control from there.
I felt like espresso machines were getting very large, plasticky, and app-integrated without actually improving the underlying technologies that make them work. The noisy vibratory pumps in particular are from 1977 and haven’t really changed since then. So I wanted to focus on making the most advanced internals I could and leaving everything else as minimalist as possible. The pump is, as far as I know, completely unique in terms of power density and price. Without spending several thousand dollars, it was difficult to find a machine with a gear pump, and adjustable pressure was also similarly expensive but this machine has those things and costs a normal amount to buy. You can also turn the pressure way down and make filter coffee.
I also saw so many people (including myself) using a scale while making espresso, and even putting a cup below the group head to catch drips, entirely negating the drip tray, so I basically designed for that! The profile of the machine is much lighter on the eyes and doesn’t loom in the corner like my old espresso machine did.
And for the grinder, basically everything on the market uses conical and flat burrs that have descended from spice grinders, and the same couple of standard sizes. Sometimes larger companies design their own burrs, but only within those existing shapes. There is sort of a rush to put larger and larger burrs into coffee grinders, which makes sense, but with cylindrical burrs, you can increase the cutting surface way more relative to the size of the grinder. When grinders get too big, maintaining alignment becomes mechanically cumbersome, but the cylindrical burr can be very well supported from the inside, and there is the added benefit of hiding the entire motor within the burr itself. The resulting grounds are just outright better than all the other grinders I have used, but obviously this is a matter of taste and my own personal bias.
The biggest downside for the grinder is that it doesn’t work with starbucks style oily roasts, because the coffee expands so much while traveling down through the burrs and can sometimes clog up the teeth. It doesn’t hurt the grinder but it does require cleaning (which is tool-free!). Another downside for both machines is the fact that they run on DC power so it’s best if you have a spot in your kitchen to tuck away the power brick.
I also made a kit that makes the gear pump a drop-in upgrade for other espresso machines, to reduce noise and add adjustable pressure.
https://velofuso.com/store/p/gear-pump-upgrade-kit
The roughest part of this process were the moments midway through development where they weren’t working at all. When the grinder is just jamming itself instantly or the fourth factory in a row tells you the part you’re making is impossible or the pump is alternating between spraying water out the side and into your face and not pumping at all. And the default thought is “Of course it’s not working, if this was going to work someone else would have already made it like this”. The route you’ve taken is fundamentally different enough that there are no existing solutions to draw on. You’re basically feeling around in the dark for months on end, burning money, and then one day, every little cumulative change suddenly adds up to a tasty espresso. And it’s not perfect yet, but you at least can see the road ahead.
Anyways, this is way more than I expected to write, thank you for reading! Tell me if you have any questions
