Lego isn’t what I remembered them to be when I was a kid. Nowadays, there are servo motors, gear, articulating parts, and power supplies for Lego that elevate them from simple building blocks to something that almost requires an engineering degree to assemble. With some 3rd party parts and mods, you can create amazingly complex, functional builds … like this automated multi-tank fish feeder on (Lego) tracks.
There isn’t any accompanying information with the video, so we don’t know the details of the build or why Mizuno even built this contraption. Sure, a commercial fish feeder would be a lot more reliable, practical, and affordable. But if that’s all Mizuno did, I wouldn’t be blogging about it, would I?
