Show HN: Kids Shelf, your kids' own little internet
kidsshelf.org7 points2 comments
Kids Shelf turns a Windows, Mac, Linux, or 64-bit Raspberry Pi computer into a private media and learning hub for children. The host computer stores videos and offline reference libraries, while other devices on the home Wi-Fi access the shelf through a browser. Parents choose what appears by adding YouTube videos, playlists, or channels for download, local video folders, and offline resources such as Wikipedia, Vikidia, and PhET experiments. Children do not see YouTube’s ads, comments, or recommendations; videos stop at the end rather than autoplaying, and the shelf has no algorithmic feed.
Parents can create a profile for each child, set daily viewing minutes, and manage each child’s PIN and allowance. Unused minutes carry over, and short math and spelling exercises can earn up to three extra minutes each per day. Shows can be marked as fun, learning, or free: learning videos use half the allotted time, while free videos remain available after the daily limit is reached. A grown-up can also disable limits for shared viewing. The program is free, open source, and keeps children’s activity and settings on the host computer; internet access is needed only to download content and updates. The host must stay on and have enough storage. Kids Shelf does not lock down the devices themselves, so children using unrestricted browsers can still visit other sites.
