Apparently they'll bring it to the next @nprofile…uc8y . If you're in Australia, you can check the event at: https://bitcoinbushbash.info/ . Would definitely love to be there in person, the vibe seems awesome! 😎 #nevent1q…p30x npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Cool upgrade! npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock https://seedkeys.xyz/wp-content/uploads/2026/02/white-board-with-generated-seed-phrase.webp https://seedkeys.xyz/wp-content/uploads/2026/02/participants-at-the-workshop-1536x1152.webp Thank you @nprofile…xl9q for hosting our workshops! 🙏 The room was pretty full, and the lightning market is really cool with all the stalls, the lights... and even a live band! 🎶 Such a great monthly event – definitely recommended if you're in Bangkok near the end of the month. For the curious, recap by @nprofile…h0j2 just below 👇 #nevent1q…jvu6 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Thanks for the cool pictures! See you around the world :) #nevent1q…nl6q npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock It's just out of the factory, and we'll open a Geyser shop in a few weeks. Otherwise, you can go to https://penlock.io and find all the guides & components that you can print and assemble the DIY way. Open source and free of charge ;) npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Knowledge first! npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock I'll run an additional workshop in Bangkok for @nprofile…wlve , on the 2nd of March. Everyone's welcome, and attendees will receive the brand new kits! 🙌 (as well as in Bob's one on the 27th :)) Link: https://luma.com/87mp8xeu #nevent1q…cqqx npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock https://image.nostr.build/f77c5831ea06ed42ddd0d89613d48422abfaf7a503c2c560e2ad5a36e44687cc.jpg 🏭 Production is complete, we did it! About 2,900 kits have been sent to our storage in Jinhua and are ready to ship, with 100 more already in my hands for quality control and the workshops in Bangkok. 📦 Next step: I will run a few test deliveries to our partners and contributors to ensure the logistics are running smoothly. Once that's confirmed, our not-for-profit shop will be ready to launch! Target date... March 21! 🚀 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock We'll have two events about self-custody this month at @nprofile…xl9q (Bangkok) in collaboration with @nprofile…h0j2 metal backup. Since we're having all these new products on the self-custody market, it's becoming difficult to identify the trade-offs at play. We'll dig into that on the 13th through a new presentation put together for the occasion! And on the 27th we'll run our workshops, hopefully featuring the brand new Penlock kits! #nevent1q…5g62 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Production update: We recently launched the production of 2,500 English and 500 Korean Penlock kits! 🛠️ Delivery is targeted for February 10. 🚀 ✅ This completes phase 2 of our Angor campaign, and we claimed the 0.019BTC milestone reward.

I don’t think I need a Codex32 one, to be honest — it looks great though! You might want to mention it on the Codex32 GitHub; they’ll definitely be interested in it! npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock There has been some demand for something like this, so I'm going to consider it. Could you send me a back-of-the-napkin quote and maybe some pictures of the Codex32 ones? npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock It is the same concept, but the algorithm has been optimized for faster paper computation! npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Amazing! 😍 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock I did 🤭 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Penlock got covered in @nprofile…dzev’s Bitcoin Tech Talk! ✨ This is a high-signal newsletter that always comes with some food for thought… I don't know how he keeps up with reading so much, year after year! Here’s what he had to say about Penlock: “If you want to back up a seed phrase but don’t want the seed phrase in a single place, this is a very interesting option. The main idea is to split a 12-word seed phrase into a 2-of-3 backup, but instead of using a computer to split this up, it uses a printable paper wheel. It uses some clever cryptography under the hood and what you end up with in your shares are other seed phrases that can get combined to recover your 12-word seed. Honestly, the makers should make these wheels available for sale as it mitigates the evil maid attack.” Well, looks like we’re on the same page… more news about it soon! 📰 Bitcoin Tech Talk: https://jimmysong.substack.com/ 📌 We were featured in: https://jimmysong.substack.com/p/bitcoin-tech-talk-477 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Thank you for covering us @nprofile…dzev! 🙏 Actually, we just had a successful peer funding campaign to start manufacturing Penlock kits and distributing them in Bitcoin spaces & conferences: https://hub.angor.io/project/angor1qfydf802v2efvxufevrfg0mvtlrxln63rkzmdxw We are still looking for additional sponsors!

Beyond software, they operate the recently opened Bitcoin Center Seoul to support education and community development 👥. We first connected at a Bitcoin public event in a Korean university, where their CEO took the stage as the MC.
