Fund Keith Mukai's FOSS Work

I am the volunteer Lead Dev for SeedSigner. We are NOT a company. The FOSS project makes no profit whatsoever from our work.

Your support to help fund my open-source dev work would be hugely appreciated!

lvgl

TODO:

Test basic lvgl_micropython compilation for esp32s3.
Begin incorporating SeedSigner-styled UI elements from: https://github.com/kdmukai/seedsigner-micropython
Test to what extent lvgl touch integration comes along "for free".

Live camera integration

Basic pure MicroPython camera driver / bindings tests.
Integration with lvgl overlay.

Backup and Restore a Raspi SD Card

Only works on linux. I've repeatedly tried to find a sequence that works on macOS but haven't had any success.

Set up PiShrink

This script will remove empty space from the backup img which ensures that you'll be able to write the img back out to an SD card that's the same size as the source SD card.

git clone https://github.com/Drewsif/PiShrink.git

Greetings to all the new Summer of Bitcoin future contributors!

As you all probably already know, SeedSigner is a 100% volunteer, completely open source project. There is no company. We have no VC funding. We have no advertising budget. If people share info about SeedSigner with others it's because they love what we've been building.

However, we have a ton in place that rivals what you'd expect to see from a well-funded corporation. Our overall code quality and code organization/structure, our INCREDIBLE UX designed by @easyuxd, our test suite and screenshot generator, github automations, internal code review processes, etc.

Some FOSS projects are more on the YOLO hacker side of things; nerds building complex, hard to use software meant for other super nerds, often with big messy late night code sprints.

Instead, we try to maintain tight professional standards as much as possible (though since we're all just volunteers, often that rigor comes with the tradeoff that we're SLOW).

These test scripts demonstrate the step-by-step speed ups that the various ccaches provide.

Scripted test sequence:

Start a build w/totally empty cache(s).
Rebuild the same target with the now populated cache(s).
Change to a new target and get some speedup via the populated cache(s).
Rebuild that target to get the full speedup.
...repeat for the remaining two targets.

The first script is for a SeedSigner OS builder that only has the built-in BuildRoot ccache.
