Catching up on finalizing and listing some of my design/product ideas -- this one has been in the queue for some time. A static setup like this can make capturing QR frames with your laptop a breeze. 🧡

I've been working on this for the last several days; it is easily my favorite signer enclosure of the ones I've created in terms of the aesthetics, the form factor, and the usability of the controls. Read on if you'd like a little "inside baseball" on this design. 👇 I heavily borrowed from the compact "Push Case" that kayth21 shared in the @SeedSigner github repo (https://github.com/SeedSigner/seedsigner/tree/dev/enclosures/pushcase) and of course have to credit @BlackCoffee for the idea to incorporate Nintendo-themed design elements (Black Coffee created a similar design a few years ago that was available for purchase for a brief period of time, and is still frequently asked about). Kayth really refined the idea of a fixed-position thumbstick topper in his push case design, as well as masterfully handled board spacing and the microSD card port. His button design is also very clever, with the lower button covers fitting around the circuit board buttons. Because of the fine tolerances between the components, I had to make some adjustments for the parts to render properly on my printers, and also modified his clamshell-style assembly to work with my drop-in approach. The DPAD topper works surprisingly quite well, especially for an FDM-printed part. The right button stack are snug with hardly any play. The memory card can no longer get lost inside the enclosure and can still be grasped with your fingers for removal. And Kayth's handling of the camera holds it perfectly centered in its respective port. This is also the first time I've offered a protective case with a printed-signer, and the grey/red color combo makes for a great initial presentation. I'll eventually also be offering a non-themed version in different colors but wanted to get this one out there immediately because it made me think of Christmas mornings when I was a kid. I was 8 years old when the original 8-bit Nintendo became available in the states, and spent many hours at a friend's house in front of a huge console TV playing the original Super Mario Brothers, before getting a system of my own a year or so later. Designers inevitably leave little bits of themselves in their work, and I'm particularly proud of this model. ❤️🩶🖤 You can find this signer available for purchase in my store at

Ooooffff… and true. View quoted note →

Attending a small event in São Paulo over the next few days coordinated by Lucas Ferreira and funded by the HRF to coordinate ongoing development of Stepan Snigirev’s embit bitcoin library AND facilitate collaboration among DIY signer/wallet projects (@Specter DIY, Krux, & @SeedSigner). Am also excited to attend SatsConf here in Brazil this week. Will be sharing more on these events as I’m able. 🧡🚀

Semisol is not the first individual specializing in secure element implementation to arrive at the conclusion that @SeedSigner is one of the best approaches to private key management available. Stateless, air-gapped DIY using commodity hardware & reproducible FOSS software is a legit security approach that mitigates the privacy leaks, supply chain risk, and other trust issues that accompany retail hardware wallets.

So excited to arrive at the finish line with this: . Custom hat materially improves @SeedSigner user experience without changing security assurances . $10 from each HAT split between our lead developer and lead maintainer . HAT & enclosure designs will be open sourced . No external investment or venture funds involved The Waveshare display hat will also be perpetually supported for any users / builders who prefer it. There were multiple shortcuts or alternative approaches that could have made this process quicker, easier, or more profitable but it was important to me to do this in what I felt was the right way. https://btc-hardware-solutions.square.site/

Just a reminder that the ability to run arbitrary code should be associated with freedom, not danger. They are trying to convince you of the latter. Cling to your God-given liberties and reject the safety of their walled gardens. View quoted note →

Good morning from Lake Satoshi — make sure to say hi if you’re here too. 🧡

If you accept sponsorship money from HWW companies that act aggressively towards open source projects... AND aren’t sharing your podcast or conference platform with those building DIY/FOSS cold storage tools... There's a question you should maybe be asking yourself.

If in fact most of the internet is going to be kyc’d, what do you think is going to happen to commercial hardware wallets that are manufactured by state-registered companies? View quoted note →

I have to give Odell props for this — today I learned that he still lists SeedSigner as a recommended cold storage option on his personal odell.xyz website.

Several people have reached out about this. There are apparently at least 10 URLs that were purchased on 5 separate days over a period of 3.5 years, all appear to have the same owner. Some of them seem intended to interfere with our ability to fundraise or accept donations? I honestly could see this sort of thing as a one-off or as a mean joke if you're having a bad day, but the pattern here comes across as something different. Given how many podcasts and conferences his sponsorships touch it feels like behaving this way towards a FOSS project should be a bigger deal? If Nostr is indeed legit with regard to wanting open source to flourish, it seems like this would be of interest here especially.
