Sorting Lego sucks, so here's an AI that does it for you

You see, Mattheij decided he wanted in on the profitable cottage industry of online Lego reselling, and after placing a bunch of bids for the colorful little blocks on eBay, he came into possession of 2 tons (4,400 pounds) of Lego -- enough to fill his entire garage. As Mattheij explains in his blog post, resellers can make up to €40 ($45) per kilogram for Lego sets, and rare parts and Lego Technic can fetch up to €100 ($112) per kg. If you really want to rake in the cash, however, you have to go through the exhaustive process of manually sorting through your bulk Lego before selling it in smaller groupings online. Instead of spending an eternity sifting through his own, intimidatingly large collection, Mattheij set to work on building an automated Lego sorter powered by a neural network that could classify the little building blocks. In case you were wondering, Lego comes in more than 38,000 shapes and over 100 shades of color, which amounts to a lot of sorting even with the aid of AI.
