I'm quite surprised how few clients support NIP-17 DMs (uses NIP-44 to not leak metadata), so I started building a tool for ourselves to provide support for our future users in a user-friendly way. I ended up with this Telegram-like web-client to send giftwrapped DM's that is actually useful for anyone. It's available via https://resin.estate/chat
I'm considering continuing developing it as a separate tool, as I think this is quite an improvement over what is available now.

End of this month my work at nostr:npub1zwne90qpp0g20u99gcr44ukc42vhyg9yfw2tuc8kv9r00er9xwlqm5tult ends, where I built www.resin.estate a nostr (NIP-99) based marketplace which aims to also offer interesting financing options, preferably without a bank.
Follow nostr:npub1zwne90qpp0g20u99gcr44ukc42vhyg9yfw2tuc8kv9r00er9xwlqm5tult posts to keep updated. If you’re interested in the technical side, I just wrote quite some thorough README’s
Frontend:
https://github.com/DaedalusLabs/RESIN/blob/main/README.md
Backend:
https://github.com/DaedalusLabs/RESIN-backend/blob/main/README.md
If you want to play around with the event kind that I used, I’ve created https://create-event.resin.estate for that. Would love to talk about the process and considerations so feel free to hit me up or invite me for a talk at Bitcoin events.

Need to add this for #BTClock / #ZapTime too 😍
-
Most of it is a joke, but if you want a #ZapTime you can order them at
https://btclock.store/product/zaptime-built-and-tested-purple-no-frontlight/
-
PSA: Here it is, the brand new, never before seen #ZapTime all-new, all-purple, trademark pending. Competitively priced $398. Expect updates once every two years. Source verifiable if you come to a secret location TBD. Authorized sellers can apply for the waitlist now.

Anyone successfully implemented Nsec Bunker remote signers with NDK in TypeScript? 👀 I do see a ndk nip46signer but looking at the code I don’t see how I could implement the nostrconnect:// string flow. The bunker:// flow I got working. Stuck for 3 hours already…
-
If you say JS, do you mean TypeScript? 😁 😁
-
I might actually rebrand the purple edition to ZapTime, what do you think? ;)

Never mind nostr:npub1fnspdyh362svdejkxqkkt4t8qvlg53jfsdn3ntxx3v2lcc5rgv8q5x8x8y I just released an update 3.3.1 with support for local public pool. Please test if it works for you :)
-
What port is the API, and can you send me the example of the API output? you can change the values and your BTC address of course and send it in a DM
-
It's already in there, just make sure you use the btc address without the worker name (so without the part after the dot).
-
You can update via https://web-flasher.btclock.dev
-
Looks like a Fleischmanns N scale start set 👀
-
I did already at the Amsterdam conference in ‘22 ;) but can do it on any meetup if there’s enough interest (At least 5 people)
-
You know it’s only adding your pubkey right? 😁
-
I will be at nostr:nprofile1qqsqhnducqt545lyw4x9t3x3p267wh6zul830xjm47p42hs42jg76rgpcvrpg in January giving a #btclock workshop! I will tell a bit about the project and then you can build your own BTClock yourself for 150 euro in sats. For the workshop I created a special edition backplate with the conference logo and date on the back 😎
Limited seats available (±10 left at this moment), if you want to attend make sure you pre-order the kit at https://btclock.store/product/btclock-workshop-set-adopting-bitcoin-cape-town/ (note that you need a conference ticket as well!)

If it’s unsoldered then that’s 100% it ;)
-
My replies keep disappearing it seems... Maybe you receive this double but it looks like the yellow headers are not soldered correctly to the ePaper boards and therefore don't make good contact.
-
New update for #BTClock, added a “Do Not Disturb” mode that stops all LEDs and (if you have it) frontlight effects so you can sleep (or work) without distractions. Can be enabled manually or based on a time schedule. Also added a second font you can choose, Oswald. Get the update at https://web-flasher.btclock.dev or if you are on 3.2.19 or later you can update using the WebUI. ✌️
https://m.primal.net/NLCJ.jpg
-
Interesting idea, multiple npubs should be possible but the different color light effects might be too heavy. It's already quite feature packaged, there is not that much RAM left but might give it a try when the mining pool stats integrations prove to be stable enough!
-
You can try with the primal relay first, I noticed that with the alby relay zap receipts are not received by the device even when you have a alby lightning address...
-
Yeah but I figured people would paste their npub anyways xD, but at this moment it only converts when you click somewhere else. Will release an update soon that converts when you paste. You can also use this tool: https://nostrcheck.me/converter/

Nope… it’s a prototype, there only exist 2 in the world 😬

Update 3.2.19 available via the web-flasher.btclock.dev
Everyone has to update their #BTClock once again with the web-flasher before auto update works again, because I changed partition tables one more time to accommodate the logos nostr:npub1tv8gmfhalwnxxquxjzeh6gtdsdz6vg7vx0s3rt7s7uuw6aujh32qn77wn2 😅

The "p" tag helps with identifying events meant for a specific user. Also the NIPs specify a way for a sender which relay to deliver the encrypted message.
That specific chosen relay could enforce authentication before kind 1059 events get delivered that are meant for a specific pubkey. I hope this clear it up a bit 😉
-
It’s connected with WiFi, still needs power using one of the two usb-c ports (back or side)
-
I'll probably regret this, but let's try it out...
At https://btclock.store/product/btclock-built-to-order/ you can now completely customize your #BTClock either as kit or pre-built. Bamboo / White / Purple and Black front panels available!
Versions with illuminated ePaper displays (frontlight) available only as pre-built versions. Probably the last few ones for a while since they were custom produced for the project and I'm almost out.

People sometimes ask "what does the #BTClock do at block X or price Y"... thanks to Emscripten I compiled the actual C(++) code to WebAsm and you can test what a certain price/block height does at http://ws.btclock.dev
For example, test out what happens to Moscow Time when we hit $1B 😉
Also has the same bugs, so please report them if you find one 😅
(Or just dive into the source at https://git.btclock.dev/btclock/btclock_v3/src/branch/main/lib/btclock/data_handler.cpp and make a pull request)
-
Make sure you have node.js with yarn installed (and fetched the submodule). You can find it here in the PlatformIO menu in VSCode:

Took quite some effort but all the #BTClock repo's are completely independent from GitHub now at https://git.btclock.dev/.
Thanks to #forgejo ( nostr:npub1rxp380rjw7vlhm38dxwre27zwt84qa6vl88930knhg24c6vkvv3smc9re7 ?) I even got the CI/CD working, see the latest run at https://git.btclock.dev/btclock/btclock_v3/actions/runs/11
The web-flasher moved to https://btclock.store/web-flasher/ (but I encourage you to compile your own firmware)
A big disadvantage is the barrier to do pull requests now though, but hopefully I can integrate GitHub OAuth for authentication...

Do you have the correct link? At
https://a.aliexpress.com/_Ew2MEjT I can order more than one and also a bundle of 5. Shipping is free after 10 euro so you could even order one bundle of 5 and then two single ones without needing to pay for additional shipping
-
Yes but for some countries I haven’t calculated shipping costs yet. Can you try if check out works for you? (It should show the costs before needing to pay), and if not, send me an DM with your country so I can check the cheapest option :)
-
Thought of this, for the #BTClock it’s either one of these options for the price. Also there are expansion ports available so you can connect multiple clocks 😁 https://image.nostr.build/bfbd47cc94c2c36dc295411b0b15a16fb6bc6acc11a3dc357e8ba0d5bfd198e2.jpg

OK, past few days were quite wild. I am currenly in El Salvador because I was attending the Adopting Bitcoin conference. My very limited internet connection here made it quite difficult to engage, I mostly just got push notifications. Hereby I want to take the opportunity to tell the story from my side.
TL;DR: We were just having fun, we thought it was okay. Apperently it's not and nvk is is so upset that he felt he had to file a GitHub takedown request. I feel that's not how bitcoiners behave.
### How it started
I have been working on the #BTClock since April '23. It started of some sort of bet where I challenged myself to make a BTC ticker as cheap as possible. I just ordered seven eInk displays on AliExpress with the intention of showing information related to bitcoin using an ESP32.
Why seven? Because the words BITCOIN and SATOSHI both consist of seven letters and connecting more screens to the ESP32 did not seem possible without adding I/O-port expanders.
Yes. The idea was inspired (among other projects) by Blockclock, which also uses eInk displays. I don't own one, so I couldn't "reverse engineer" or use any direct inspiration of it but the way you can combine multiple eInk displays to display information in an useful way is very limited.
After getting the schematic right. I created a 3D printable case for it (https://www.thingiverse.com/thing:6009628) and named it BTClock after someone's idea in the Dutch Noderunners community. Since it consists of seven characters I thought it's the perfect name since it fits the seven displays too.
nostr:note19zp3c8lsm4s5lwvuscu4dll3clkzvajrwthvqed5q7s83mazrr2swc6mqe
### May 2023
This allows you to create a BTClock for ±70 euro (if you own a 3D printer).
I shared the progress of the project in the MakerBits telegram group. Ben Arc checked with nvk how he felt about it, and I have seen his responsse where he replied with that he felt honored and that I should go ahead. In hindsight, I should've asked Ben to forward this to me but I wouldn't expect this to "haunt" me like it did last week.
After sharing the very spaghetti-y schematic in some Telegram groups, someone replied that he was working on making an actual PCB out of it. After some DM'ing back and forth we got our first PCB prototype that needed some work. After 4 iterations we finally got it how we wanted and were able to sell DIY kits. The PCB is real artwork, so we wanted to show it off. Therefore we added a acrylic backplate to be able to protect it while still able to see the proof-of-work by Madbo, the PCB artwork designer. We used a lot of through hole components to make it accesible for anyone who has a soldering iron.
### August 2023
In August 2023 we finally got the kits ready, while the initial plan was to only sell the DIY kit within the Dutch Noderunners community, I brought smoe with me to Baltic Honeybadger '23 as well, where it proved to be pretty succesful while sitting next to Ben in the chilling lounge.
I got a lot of encouraging and positive remarks about the project, including Daniel Prince (@princeysov) who tweeted about this (https://x.com/Princey21M/status/1698257536418267624).
It appeared that this tweet firstly poked the lion, since nvk sent some of his coinkite employees to me after this tweet, a group of 4 people asked a lot of questions while filming me (without my consent, I didn't realize this when they were asking it but when they walked away it was clear to see the iPhone was recording video).
Not a lot later, nvk sent out a tweet which was clearly about the BTClock project without explicitly mentioning the name (https://x.com/nvk/status/1698423362819682400)
However, in my opinion this did still fit the message I read he wrote to Ben that he was more flattered than upset. It was only then when I learned about how he reacted to Foundation Passport and how he behaves regarding the SeedSigner project.
https://m.primal.net/MaIv.png
### March 2024
During Bitcoin Atlantis in March 2024, there was a nice space for the MakerBits projects including the BTClock, the software by this time has many improvements, including real-time new block notifications by utilizing the Mempool.space Websocket API. Since the hardware is also open source, many alternative faceplates are available including a stainless steel one and a completely white one. Multiple people witnessed nvk walking passed the maker space while looking at me, but he did not engage or whatsoever. I would expect if he would take offense by the product, he would've approached me by now but he didn't. He does know who I am though, both in real-life and I'm posting enough on my social media accounts (Nostr and Xitter) to find me there as well.
### Fast forward to November 2024
A lot has happened in the development of the BTClock, among other things I added a BitAxe integration and Nostr Zap Notifications to the software and we managed to add frontlight to the eInk displays which I really think sets the BTClock apart from other "tickers" like the Blockclock mini.
The Blockclock mini hasn't had any updates for two years (since October 3rd, 2022) which seems to be like the Blockclick mini can be considered end-of-life.
I therefore was very suprised that when I woke up on November 14th, I received an e-mail that the BTClock GitHub organization was flagged because of alleged trademark infringement of the BTClock.
This was according to a report by Coinkite to GitHub. The letter I shared in the MakerBits Telegram group was ONLY sent to GitHub, not to me (although I haven't been home for a while so I don't know something is waiting in my physical mailbox).
Luckily git is decentralized version control and there are already mirrors of the hardware and software source available. Also GitHub allows me to appeal but haven't taken the chance to do so.
Although I do understand that the concept of trademarks exists for a reason, I feel this a very cowardly move and certainly not something that I would expect from fellow bitcoiners. Just sending me a DM on Nostr, X or Telegram is the least I would expect. I don't mean to offend or infringe, and would be happy to discuss options if open to it. Either in DM or out in the open.
I'm all about transparency so nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 here is my invitation to discuss this out in the open. I'm sorry that we seem to upset you. what is it that bothers you, can we find a way to let the projects co-exist? Or even see if the BTClock software can adapted to your Blockclock mini hardware.
-
Also, you can play around with how it looks like at https://ws.btclock.dev it is compiled from the actual C++ code with emscripten to WebAsm so any features/bugs in the code of the actual clock appear there as well
-
It’s not the eInk itself, it’s my shadow super open source #BTClock code 😎 you could even adapt it to the Mow notation so 0.1M

Its already 7 digit, and the firmware is 8+ display ready. Someone just needs to make the hardware https://image.nostr.build/bfbd47cc94c2c36dc295411b0b15a16fb6bc6acc11a3dc357e8ba0d5bfd198e2.jpg

Clone it, distribute it, fork it, modify it, verify it and/or improve it.
You could even modify it to run on similar hardware that is End-of-Life.

Yay, finally. See you soon!

We’re only in Berlin for one day, it’s quite a long trip (3 hours one way). We probably walk into each other at the conference or one of the side events then.

Sure nostr:npub1ytm3v8mkup6mnc9z2zjy0zz2czdsfd3kal7hcup6jgu5a5lm885qhup3z6 if you’re in Berlin now as well nostr:npub1a8us7vr738n7cvdxh0gdtnt5qzrk4qe3qklhmsrs45llq2k48agqjkrvn3 and I are sitting in front of the “El Portal” restaurant
Quality is better actually since I think they use locally grown fruit and vegetables

It will switch to suffix mode when the time comes, with higher prices the last decimals become less significant.
Or you can chain two of them and then you have 14 displays, there are SPI and I2C expansion ports available.
