I have written a Python script that takes my Mastodon feed and turns it into #teletext pages, and I consider this time well spent.

Rather amazed at the reaction to this post from yesterday. My phone has been buzzing with notifications all day. Who knew there was so much affection for teletext out there?
For those who asked, yes I will make the code public soon, it needs tidying up a bit but then I will put it on GitHub.
And thank you for all the kind comments - itโ€™s nice to know my geekiness is appreciated. ๐Ÿ˜Š (I suspect birdsite would not have been so lovely)

@Hampo I've spent hours and hours -- for BBC R&D -- parsing DVB streams, so I happen to know that the teletext line actually has an official table encoding within DVB, which is why I made the (frankly tongue in cheek) comment.

Nice to see people doing this sort of thing.

@steve The screenshot is from the online teletext editor at https://zxnet.co.uk/teletext/editor/ (I imported the teletext output into it to check it was correct).

But my code outputs a TTI page, which is a standard teletext format. It could absolutely be used with an inserter such as VBIT (https://github.com/peterkvt80/vbit2) to generate real VBI teletext.
