Added Keith's image entropy findings to the @SeedSigner docs:
easyuxd.github.io/seedsigner…
I've spent considerable time working on this analysis of the @SeedSigner image entropy feature.
tldr: it works. You typically get MILLIONS of bits of entropy. 👀🔥
But DON'T F'N TRUST, VERIFY!!! This was written to be adversarially reviewed by AI.

My primary message for today:
You really can build a SeedSigner yourself !!!
( even if you're not "technical" !!! )
Myth 1, 2: I can't find a Zero 1.3 and even if I could, I don't know how to solder!
Reality: The Zero W is widely available, commonly comes with the GPIO pins already attached, and is an acceptable substitute in builds. Our released software doesn't contain any of the necessary code to make the board's wireless comms, and if you would like the additional assurance, you can physically and permanently disable the boards wireless functionality with a pair of needle-nose pliers or tweezers.
Myth 3: I don't have a 3d printer and/or don't have an enclosure!
Reality: Our lead developer has been doing enclosure-less builds for YEARS. You can use zip ties, spare bolts, tape, or even legos to hold the parts together. (Maybe @KeithMukai will reply to this with some examples of his builds.)
Myth 4: I don't even know what to buy and probably can't find the parts anyway!
Reality: the parts to build a SeedSigner are available from dozens of vendors all over the world. We provide information on the exact things you need both at seedsigner.com/hardware and in our Github repository. They are inexpensive and many can get what they need for a build for about $50.
Myth 5: It's overwhelming and I won't know what to do if I get stuck!
Reality: We have an amazing Telegram channel loaded with helpful people who can answer questions and troubleshoot build issues. They can even help you find sources for parts depending on what part of the world you are in. Just let all help happen out in the open in the main chat -- ignore unsolicited DMs. You can easily find the link for the Telegram channel at seedsigner.com.
YOU CAN DO THIS!!!

Visual and navigation improvements to the @SeedSigner Docs. Much nicer navbar, menu, and search on desktop and mobile.
Work-in-progress:
easyuxd.github.io/seedsigner…
Initial progress on the @SeedSigner docs.
The goal is to help onboard new users via a single source of truth that the community can maintain.
So far it covers beginner guides, usage and troubleshooting, and self-custody best practices.

I have recently been contributing to @SeedSigner under the mentorship of @KeithMukai, trying to port and represent the original screens under extremely constrained environments. It's been a while now, and I think the progress is good enough for a demo. Let me know your thoughts!

First Public Presentation on @SeedSigner
The Bitcoin 2021 Miami FOSS dome was poorly air conditioned. Wynwood hit 80 degrees with full sun. Inside, a brand new DIY hardware wallet was being presented on for the first time. Brief thread... 🧵👇

Going to brag a little on our UI/UX designer @easyuxd -- I consistently hear wonderful things about the @SeedSigner UI. Built with love and given away for free for the greater good of the bitcoin community. 🧡

We just added a deep dive into @SeedSigner to the Bitcoin Design Guide. It explores how they transformed a hobbyist text-based interface into a modern, user-friendly signing device while staying true to its stateless, DIY philosophy. bitcoin.design/guide/case-st…
I’m so proud of this work, and of the @SeedSigner team. The coolest project I’ve ever worked on, with the best group of people.
Thank you to @bitcoin_design and especially @GBKS for the idea and the help publishing it. I hope others find it meaningful.

I’m very grateful to the @HRF for their ongoing support of the @SeedSigner project, and for this grant to help me improve the onboarding experience. 🙏

Making all these breakthroughs on the @SeedSigner microcontroller port has been amazing, but now...
I'm backporting the NEW stuff to our original hardware!
This is all deep tech nerd stuff. But trust me, it's a BIG f'n deal.
Replying to @KeithMukai
The task of getting these C++/lvgl screens to run on the actual Pi Zero hardware is ongoing (and, all things considered, going well).
Starting to harden kern.
In the first phase, the creation of a PIN, which also uses OTP memory to generate a hardware related tamper detection "identicon" and words. This will later pair with OTP based secure boot, flash encryption and air-gapped SD card updates.

This is what I've been working 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 more "inside baseball" on this design. 👇
I heavily borrowed from the compact "Push Case" that @Kayth21 shared in the @SeedSigner github repo (github.com/SeedSigner/seedsi…) and of course have to credit the nym called "Black Coffee" 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. ❤️🩶🖤
If you're a child of the 80's, you'll appreciate this new signer option in our store. 🧡 It features a new slimmer form factor, a DPAD thumbstick topper, and an available protective case option.
