I made this tool to scratch my own itch.

It's a very simple web app that turns my Kindle Scribe into a Lightbox for tracing. It's made with pure HTML and JavaScript; no framework and no "splash". I haven't bothered to make it look nice.

I use it to snap pictures and upload them to my Kindle Scribe for tracing into my digital notebook and to create pen outlines for painting projects.

I made a free version available for this Show HN post.
