I always wanted to have an easy way of accessing news videos from national TV channels, without having to subscribe to them or pay for third-party tools that do this. So I built my own one: The Video Finder (http://www.minerazzi.com/tools/video-finder/video-finder.php).
Users can submit a YouTube channel id or a url containing one and the tool returns a links list in feeds format. Videos on other categories or topics can be accessed with the tool. The tool is based on a previous one (The RAR Parser, http://www.minerazzi.com/tools/rar/feeds-parser.php).
Now I have a way of building web pages on a given category (Human Resources, Chemistry, Genetics, Health, Sports,…), listing relevant channels. Great for educational or research purposes.
