So I looked into this a bit and found out that iOS has built-in support for rendering USDZ 3D models via https://developer.apple.com/augmented-reality/quick-look/. So any iOS app can preview USDZ files with minimal code using QLPreviewController. If Damus supports USDZ URLs in notes, iOS handles the rendering automatically - including AR mode where you can place the object in your room. Pretty cool, but unfortunately limited to Apple's ecosystem.

#WeFixedTheFilters
The shop page has been revamped! It's now much easier to navigate, and providing category and other filters to make it easy for you to find the products you want!
Should we add a search field as well?

LNs sender privacy is unmatched. The receiver has no way to know how many hops the TX made on the way to him, so pinpointing the sender is virtually impossible.

Easy to integrate since I'm using btcpayserver in the backend. But why would you swap perfect sender privacy and instant settlement for non instant settlement with similar privacy?

Wow, this is insanely cool and I have no idea how I missed it tbh. A decentralized marketplace for 3D models is a great idea which I would love to integrate.

2026-01-30 15:08:59 UTC

I've been working on something and while it's still rough around the edges, I think it's time to share it and start building in public! 👀
Introducing Pod21 - The Decentralized 3D Printing Network
https://image.nostr.build/1ba2edc4b07dba88d69e399012806ea907e2fa408a4a0b59a5960b8ef7e55d7f.png
Pod21 is currently a marketplace but strives to become a permissionless network connecting people who need 3D prints with local makers who have printers, built on Nostr and Lightning!
No accounts, no passwords - just your Nostr identity. Pay with Lightning, get your parts shipped.
How it works:
1. Upload your STL or 3MF file
2. Pick your material and quality settings
3. Choose a provider from the interactive globe
4. Pay the Lightning invoice
5. Provider prints and ships directly to you
The Why:
The 3D printing community is full of people willing to help each other, but there's no good way to connect them globally with instant, borderless payments. Centralized platforms take huge cuts and require endless KYC.
I wanted something that just works - for bitcoiners, by bitcoiners.
The stack:
- Nostr for auth and messaging (NIP-07, NIP-17 DMs)
- Lightning via BTCPay Server
- No accounts, no passwords, no email required (except for customers, for now)
- Providers get paid instantly after shipping
The Slicer:
This was easily the hardest part to get working and took weeks of trial and error! For slicing the 3D-models, a dockerized, browserized version of Orcaslicer is being remotely controlled by the backend to slice files with actual real life print profiles for existing printers. This guarantees correct values and enables instant quoting, but it also means that slicing can take quite a bit of time, depending on the file size.
The slicer is currently still limited in functionality, but soon I will add options for multicolor and multipart prints as well advanced autosupports and more.
The Bot:
Follow @npub1p0d…f8tq and send a dm to our bot with GM or /help as the content and it should introduce itself and explain the service to you. It also helps providers by sending out order details and can mark orders shipped, send tracking info and more. The payout service via the bot is currently inactive until sufficiently hardened. It will also GM you back, always! :D
For Makers:
If you have one or more 3D printers sitting idle, you can earn sats printing for your community.Register as a provider, set your rates, and get order notifications via Nostr DMs. Current platform fee is 5%. This fee is not static and will go to zero over time based on a yet to be implemented volume dependant "halving" routine.
And of course, it's open source:
The entire codebase is now public under AGPL-3.0. You can verify exactly what's running, self-host if you want, or contribute improvements. Clients will talk to each other further down the road to really make this a decentralized platform, currently there's only one client up which you can try out here: https://pod21.com
GitHub: https://github.com/gobrrrme/pod21
Nostr Bot: https://github.com/gobrrrme/Pod21-NostrBot
This project is still very early, and I'm constantly improving it on a lot of fronts, so breaking changes may occur at any time!
Feedback, support and contributions welcome - DM me or open an issue.
Let's decentralize 3D-printing, one layer at a time!

Today we welcome a new type of DIY Self Custody Device at Go Brrr!
We're thrilled to start offering the first Bitcoin Signing Device running Krux 👀
If you've never heard of Krux before, you've been living under a rock, here's a quick rundown.
Krux is open-source firmware that turns affordable Kendryte K210 devices like the Maix Amigo or M5StickV into bitcoin transaction signers. It also provides tools for creating and recovering mnemonic backups, with optional encryption for added security.
Ready-to-use devices like the Maix Amigo, Yahboom, WonderMV or TZT feature large touchscreens for easy operation, which is ideal for a plug-and-play experience. For DIY enthusiasts, Krux also supports development board kits for custom hardware builds.
The firmware works seamlessly with popular coordinator wallets via QR codes, SD cards, or thermal printers, enabling transactions and mnemonic backups in an offline environment. Krux is a software for power users who value a vast amount of configuration options. Furthermore, it's compatible with our beloved SeedQR Standard and Titanium Backup Plates which makes it fit perfectly into our ecosystem of DIY signing devices and related accessories!
To get started with Krux, check out the official website: https://selfcustody.github.io/krux/
https://image.nostr.build/7f21626b01b7232e1c7f022f23118e547d7cf9afb59c9c135f5af9da8ff59b7d.jpg
The underlying hardware is the stunningly beautiful TZT CanMv K210 Vision Module with the following technical specifications:
- 2" / 240x320 Capacitive Touchscreen
- Laser Engraved Anodized Aluminum Body
- 5 Physical Buttons
- GC2145 2MP Camera
- 57 x 41 x 16 mm
https://image.nostr.build/1d3712d869b4eddec866c2c19277ad6e469a4342bf063857991a412d6cdf2422.jpg
The signer comes preflashed with Krux firmware and is delivered in a 3D-printed, custom designed, protective snap-lock enclosure for secure and stylish storage.
A limited number of Krux Signers is now available in the shop. As usual, parts of profits will be used to support the developers of the Krux project to make further improvements and additions to the software possible!
https://image.nostr.build/c03901bfd1f2f307ad2037668c80d8edc2b78fc86c80aca59e29f54e0bc2719e.jpg
Thanks for reading, now go buy or build a DIY Signer!

Miners send shares to nodes which validate them and if needed send them to the network. Each step takes time, time is money. WiFi increases the time the share takes on its way to the node before the node can even do anything with it.

Are you still mining over shitty WiFi, hoping for a block while industry giants optimize every last bit out of their setups to avoid unnecessary milliseconds of delay because they know it will decrease their chances if they don't?
What's a valid hash worth if it doesn't reach the mining node in time, or at all?
While I don't know an exact answer to the second question, we do have answer to the first.
You are not limited to WiFi anymore.

Ready to build your own Solarbit? Now you can!
DIY Kits, PCBs, Printed Part Kits and a digital file download containing all the 3D printed parts are now available here: https://www.gobrrr.me/category/solarbit/
https://image.nostr.build/1c0118b559a9673be2e6256cda589866c40eb31ceae6719d7198865efbfaac38.jpg
What is Solarbit?
Solarbit is a mostly 3D printed, self-sufficient, offgrid capable, Solar Tracker device that maximizes energy capture by following the Sun. Equipped with two solar panels, Solarbit uses advanced automation to track the sun’s movement throughout the day, ensuring optimal energy production. This energy is stored in a battery (battery not included), which can power things like bitcoin miners, nodes, beercoolers, rc-cars and a myriad of other things.
For US Customers Solarbit PCBs are already available at:
https://cryptomachine.shop/
And we even got Australia covered with https://shopbitcoin.com.au/ who will start stocking PCBs, Kits and possibly more very soon™
Find out more about Solarbit here: https://gobrrr.me/solarbit/
And on youtube: https://www.youtube.com/watch?v=mdGpmd3NaSw&list=PLHwGyXItgOkS4VrQXQM7NuYsWrxpfUgKA
