Snapshot: https://archive.is/FVUHe There's an embedded YouTube video in the article as well, that appears twice. First at the top and then again further down. https://www.youtube.com/watch?v=u6sukVMijBg There are also several videos in the article that are hosted on the same site as the original article (so on the .ru site). Those are not included in the snapshot unfortunatelly. You'll see placeholders and the associated text that describes them but you can't view those via the snapshot. It also contains a link to a GitHub repo at the end. https://github.com/portasynthinca3/swl01u

Thanks! The dot matrix is actually eight 5x8 characters, or 320 bits in total. I'm packing those 320 bits into the the 4 bits per byte that are available to us in this shell protocol. Plus, another 9 bytes for the packet header and footer. Looks like I wrote 92 in the article, I must have miscalculated that. I'm not using the full 7 bits because figuring out a way to do so turned out to be way too hard for me, so I opted for a solution that is negligibly worse than the optimal one, in comparison to the original one. If you're wondering about the exact algorithm, consider checking these files out, but please keep in mind that I haven't cleaned the code up yet: https://github.com/portasynthinca3/swl01u/blob/master/fun/bi..., https://github.com/portasynthinca3/swl01u/blob/master/fun/ba...
