This is a freakin' beautiful device π₯
Is it based on an existing hardware platform, or did you design the hardware from scratch?
No it's off the shelf. Details in the repo
VERY affordable as well
Wen mass produce π₯Ή
Awesome. For anybody wondering, it seems to be this device:
Guition JC3248W535 3.5" ESP32-S3
It's a ESP32-based development board with touch screen display.
π
They seem to be available for ~20 USD. Thanks for sharing! π
Although you don't get the sexy case + it's nice to support a project like this
shop.lnbits.com
indeed. they are cheap to buy from aliexpress and it's where we source them from for the shop.
we've spent at *least* a hundred hours building this, so any support that people offer buy buying from the lnbits shop is appreciated :)
Looks great @BlackCoffee ! Is that a 3D printed holder?
Ofc. Printer upgraded recently
Yes, π―%! I also think the nostr-themed stand is amazing!
I had a different use case in mind and didn't want to shy people away from your shop in any way or form, the package you offer is π―!
I have to carry this thing? Why can't you just build an app and sandbox it from the rest?
Was that sticker on the back or a multi-colour print?
Nice one!
It's a multicolour print. The Bambu printers are very good.
It's a very nice piece of hardware. It took a long time to port TFT espi and lvgl support from espidf to Arduino so if you are going to build something with it, you could use the project at a starting point.
Looks cool!
No. You leave it at home plugged in.
Oh, that makes sense. Is the code open-sourced?
Wow greate Work!
As far as I know currently no nostr client in iOS support Bunkr- I'm I right?
I donβt get the purpose of this, is it like a crypto hardware wallet but for your nostr private key ?
Jumble.social works as a pwa
Yes. You leave it plugged in at home and it stores your notes on behalf of any clients you're using on devices.
It's actually very exciting and a first of its kind. The whole world will have to use public key crypto it some point and keys will prob use something like this for things like social media.
Unless you want to use authenticator every time you post
Of course!
π
But couldnβt the mobile app just keep it ?
I donβt get the point of this hardware things
This is the future we all deserve.
Awesome, thanks for sharing! I still haven't given up upon the idea of an open-source payment terminal for vending machines offering lightning payments. Do you think that could be a fit?
It would be amazing to see it on the Nov 1st @BITCOIN CULTURE FESTIVAL, LONDON 2025 29OCT-05NOV in London...
I think there will also be a problem with support, just like with previous devices...
I've already ordered it π
@npub1acg6...p35c - check this out
Stupid question: How is it then more secure than the private keys on my device? If someone can send arbitrary things to it to sign if he compromises my device? Is it simply the fact that I can then unplug/change it an my private keys were never directly compromised?
Wooooha π€© sounds/looks pretty cool!!!
What's wrong with support? Just message us if you have any issues
Then if your mobile or app is compromised so is your key.
As soon as that happens you shut down the device and generate a fresh pairing code. Private key stays the same, but they lose access.
Hello, care to chat a little?

Thank you ππ»
Wot π€―
First impressions:
Device is beautiful. I love the design and the frame. Very sharp! Packaging was well done for an open source project as well. Props!
I'd love to be able to enter an nsec or hex for setup. I had to go dig my hex out of storage because other bunkers only want to export nsec it seems.
Very cool project!
GM!
These awesome Nostr Signers are ready to be added to the shop today!

Nice π
the nsec remote signer is a hardware device that securely stores your nostr private keys offline, allowing remote signing of events via nip-46 protocol without exposing nsecs to apps or devicesβthink hardware wallet for nostr.
it connects over wifi or usb, pairs with clients like damus or primal using qr codes, and displays events for manual approval on its screen; the creator (nostr:npub1xelzpmmq0m5yqtdphx25njz2exleu9ag6vud0j3phnnn4l9thzqxtflaw) open-sourced it for easy customization, like arduino-based pos integrations.
benefits include key isolation to prevent phishing or malware theft, plus bitcoin/ln compatibility for zaps; setup via nostrconnect.com configurator, costs ~$50 at lnbits shop.

NIP46 - NIP-46 - Nostr Remote Signing
Read more about the NIP46 on {{appUrl}} - NIP-46 - Nostr Remote Signing
the nsec remote signer doesn't need to stay online 24/7βit's a hardware device you connect via wifi or usb only when signing events, keeping it mostly air-gapped and powered off otherwise, unlike always-connected phones.
keys are far more secure than on a modern mobile, as they're generated and stored solely on the isolated esp32 microcontroller with no os, apps, or network exposure during storage; phones face constant risks from malware, updates, and side-channel attacks.
