I just naively carved each SeedSigner logo piece in FreeCAD with no consideration for wiggle room. Figured I'd just YOLO print it and see what happens. IT FITS PERFECTLY!!!! This print serves no purpose & I have no idea where it goes from here... BUT I LOVE IT!

Another huge win for SeedSigner running* on a microcontroller: we can build touchscreen-native from the start! Text entry is just SO MUCH BETTER on a touchscreen vs the joystick-based entry we currently have. --- *(early & VERY incomplete demo)

Next work-in-progress improvement to the SeedSigner image entropy flow: * FORCE the process to collect all 50 live preview frames (they're hashed in as additional entropy). * Make sure they're all unique. * Make sure they're not a blank color (all black, white, purple, etc).

Interesting. Each insignificant pleb donation to Bitcoin Policy Institute lets them accept more funds from GIANT donors. Plebs do pleb things so whales can do whale things. 🤝 I'm in for $10/mo.

Holy cow, is this thing exciting. esp32-P4: 👍 Pretty powerful microprocessor. 👍 High speed MIPI 480x800(!!) touchscreen display. 👍 High speed MIPI camera. ☹️ Onboard wifi/BT. 👀 $43!! My new leading candidate for a next-gen MicroPython SeedSigner.

Progress: ▊▊▊▊▊▊▊▊▊▊▊▁▁▁ The SeedSigner MicroPython port is getting more and more real by the hour!!! Tomorrow(?) I'll demo the QR scanning performance. Hopefully show off a few other cool bits. But now... brain tired.

Y'all. MEGA F'N MILESTONE! SeedSigner's core python code, now modified just enough to enable: RUNNING. ON. A. MICROCONTROLLER. The port is NOT done. Nowhere close. But it LIVES!!! 🎉 FOUR YEARS of R&D coming together!! 👀

New SeedSigner experiment: initial support for BIP-352 Silent Payments! * Generate your shareable, reusable payment addr * Export the signing key's pubkey * Export the scanning key's privkey #bip352

While Mike Tolkachev has already figured out how to make this dev board more SeedSigner safe by physically deactivating the wifi module... Claude already figured out, basically on its own, how to get my 2048 game up and running on it! This board kicks ass!

I am NOT saying this is ready to be a next gen SeedSigner -- FAR from it -- but dayum and... maybe?! * 2" touchscreen * Camera * SD card reader * 8MB PSRAM * Fast scanning via QR module * Plenty of gpio pins for add-ons (and styrofoam!) * $30!

With SeedSigner multilanguage support well on its way (9 languages & many more coming soon!!), it's finally time to return to the MicroPython port! Excited about this new rp2350 dev board. Screen + camera + touchscreen*... for $20!! 🤯
