inspired by @DesobedienteTec , i built my own @SeedSigner from an R36S. dont mind the camers, its just what I could put together with what i had at home it will works with any usb camera.
watch until the end

Self-custody should feel like a natural part of owning bitcoin.
With our new auto-withdraw feature, eligible @CashApp customers can buy BTC in Cash App and have it automatically moved to Bitkey for safekeeping.
Set it once, keep stacking, and safeguard your BTC with Bitkey.

Having it work on the esp32-P4 is huge. It's likely compiled C code that's called by python.
Since @selfcustodykrux, @SpecterDIY, and @odudex's #Kern are all targeting the P4, should be an easy add.
ALSO: Can compile that same C code for the Pi Zero. So ALL platforms win.

Now this is SUPER COOL! Roll 100 dice, scan the results with your SeedSigner (and easily verify the scan matches reality), and VOILA;
Seed.
Yowza, reading dice rolls w/@SeedSigner camera!
What a formula:
* Go to @tabconf (moar, please @miketwenty1).
* Demo proposed feature to us in person.
* Attend my workshop, get esp32-P4 hardware.
* Build an even better version!
I'm super impressed, @onedigitmoney!

I totally get the offline laptop thing, I did exactly that for my earliest cold storage. But with what is coming to SeedSigner, SpecterDIY, Krux and Kern, these microcontroller projects are going to offer increasingly decisive advantages over the offline laptop approach. With support for dozens of development boards any association with bitcoin goes away so you sidestep all of the supply chain risk; you lose the attack surface of an entire microprocessor OS + app; you get better assurances wrt wireless comms being truly disabled; you can get something brand new still at a very low cost; the form factor is much easier to use and store; and the UX becomes much more intuitive and specialized like a HWW rather than a general purpose computer/OS. The advantages of FOSS + DIY are going to become undeniable.

Pretty cool: @RichLassiterMD got one of the @SeedSigner dev boards and then took it to @ALewin's @tabconf AI hackathon.
Rich created a smart home controller app that's a decoy on top of the SeedSigner MicroPython port!
He is NOT a programmer. But did this in 1hr!
The @SeedSigner workshop at @tabconf was a success!
About 25 people showed up, received their free esp32-P4 dev board, and nearly everyone had flashed my work-in-progress MicroPython port to their board by the end of the hour!
Excited to see what they build!!

some people asked for my method. here's an overview how. lyrics & story board, me then checked in claude, suno song, grok plate images, all video local using LTX image root of claudia goes back to @analbology who started it all. proudly not-slop slop.
