It's still a work in progress, but seems stable enough for "public beta", so by popular demand here's a standalone version of the parametric clock generator I recently added to my online teletext viewer: zxnet.co.uk/clock/#templ...

QTeletextMaker 0.8.2-beta released. For AZERTY keyboard users the Level 2.5 #teletext editor has alternate keymappings for inserting colour attributes, using the top row of letters without having to Shift the numbers every time. Windows .exe from the zip as usual: github.com/gkthemac/QTe...

Ever fancied making your own Ceefax pages? Latest version of my #teletext editor is at github.com/peterkvt80/w...

A (horrible) alternate reality, inspired by yesterday. #Cloudflare #Teletext #TeletextArt #Art

Were colour bitmap graphics possible in #teletext ? With Level 3.5 DRCS they could have been. But hopelessly impractical; all the bitmap data is stored across 8 subpages and you'd need to wait for them all to come around. Just for that one picture that's the biggest size possible in 16 colours.

Level 2.5 #teletext needn't be that hard. Sometimes a simple palette remap is all an artwork needs to stand out.

QTeletextMaker v0.8.1-beta released. No new features but the Level 2.5 #teletext editor has had a major bug squashed that sometimes caused the central page editor widget to get "lost" or squashed into a tiny corner of the main window. Windows .exe from the zip as usual: github.com/gkthemac/QTe...

QTeletextMaker v0.8-beta released. The Level 2.5 #teletext editor now renders DRCS characters and slightly improved diacritical'd G0 capital letters. Grab a Windows exe from the zip at github.com/gkthemac/QTe... (mind the SmartScreen warnings!) or compile the source on Linux with #Qt6 and CMake.

All the tellies up and running at #ChunkyFringe

As if black foreground wasn't controversial enough, should modern Level 1 and 1.5 #teletext decoders obey the double width and double height control codes? The ETSI spec says they are Level 2.5 only, but in real life some Level 1 and 1.5 decoders made since about 1999-ish do interpret them.

Another reminder that the #ChunkyFringe teletext editing system is online for anyone to have a go at creating real teletext pages: blockparty.zxnet.co.uk Channel your inner @mrbiffo.bsky.social* and come and admire your creations in all their chunky glory on CRT tellies in Harrow this Saturday!

Ahh, good old #teletext with no cookie pop-ups, no registrations or sign-ins, no autoplaying videos... and no sudden geo-blocks either.

For the upcoming #ChunkyFringe the #WeeklyTeletextArt prompt is "Chunky" and/or "Fringe". Here's a #teletext nod to an old chocolate advert; regrettably trademarks have had to be altered for legal reasons.

One week today... we're going to be doing a whole bunch of nonsense at Chunky Fringe. It's all the fun of Digi Live without us having to spend a fortune on props. Details here: www.arbitraryfiles.com/events/cf25/...

The ChunkyText user pages magazine has been cleared out ready for next weekend, and the edit server is LIVE NOW. blockparty.zxnet.co.uk I thought since we have a week to go until Chunky Fringe maybe we should call those a #WeeklyTeletextArt prompt for anyone needing a bit of artistic inspiration 😁

My first ever attempt at getting a Level 2.5 #teletext DRCS bitmap onto a real TV! 24 monochrome characters is the maximum you can have on screen; the bitmaps (or Pattern Transfer Units as they're called) are downloaded from a separate hidden page. DRCS rendering in QTeletextMaker coming soon...

I've finally got around to looking at how I could port teletext-twitter by mastodon.radio/@markpentler to the Bluesky api, and it turned out to be way easier than I expected! At least for the mode I wanted. I've even added a couple of things teletext-twitter never had 😄 zxnet.co.uk/teletext/vie...

Dear friends, don’t buy this. It’s shit. Just don’t, ok If you do, it will drive you nuts Thank you for your attention, we now return to normal programming

My word, you lot do love #Teletext don’t you. Well done BBC Videobook of British Garden Birds was the 1st LaserVision Disc with Teletext BBCs Service was called Ceefax = See Facts CAV Dual Sound, Birds one track, David in other Index & Subtitles Technical marvel in its day #LaserDisc

Been working on a Betamax Digitising Job this afternoon I always run the tapes to end, you sometimes find something that’s been forgotten About 10 mins after the Wedding Video finishes, in all its Analogue Glory About 30 mins of Ceefax in Vision Oh happy days Yes yes, I am grabbing it

There may be no Digi Live this year, but Chunky Fringe just will not stop, ever. On Sat 4 Oct you can get your teletext on back in the fine, familiar surrounds of Harrow Arts Centre. “Mad” “props” to David Walford for organising another free retro tech feast. www.arbitraryfiles.com/events/cf25/...

This is the best thing about Ceefax. No cookie agreements, no stupid pop-up sign up forms, no clutter - just the bare necessities and a three-digital number.

i found some old progress pix of a #teletext #pixelart goldfinch i didid. going from the original sketch to adding the colour codes in, and then moving to 2.5 colours for more realism

There's nothing that divides #teletext enthusiasts more than whether or not black foreground attributes should be interpreted on Level 1 decoders. ETSI spec says they shouldn't, in real life all decoders made since about 1990 do. The test below shows the problems that can happen on old decoders.

Today’s Lesson from Archivist Andy Don’t store CDs, especially CD-Rs, in these Fabric / Tea Bag sleeves. If the environment you’re keeping them is even slightly damp, you increase the risk of Disc Rot These CDs have come from a wonderful collection So badly damaged, even my Denon can’t cope

QTeletextMaker v0.7.2-beta released. The Level 2.5 #teletext editor can now import & export pages in EP1 and HMS datastream htt formats in addition to the existing TTI and t42 formats. Grab a Windows exe from the zip at github.com/gkthemac/QTe... or compile the source on Linux with #Qt6 and CMake.

Ouppy!!! :3 #teletext #pixelart drawing of my bestie @ash4val.bsky.social 's adorable #oc 🐶

Majority want Freeview saved from the axe, according to new research rxtvinfo.com/2025/majorit...

So, erm, it's been over a year since I first announced I could create a DVB-T Mux with teletext. I know I said I'd explain how it all works - but it turns out doing dvb-t stuff *well* is stupidly difficult! I promise I'll have something written up/filmed about it eventually!

A Level 2.5 #teletext parody of the original Microsoft Store handbag icon. The blue-to-black gradient is only there to hide the held mosaics that allow the top corners of the handle to be different colours, then I went a bit overboard with nested Objects to implement a real vertical gradient.

The Teletext Archive has linked up with @ZXGuesser's archive, which has loads of recoveries, and then some. We have an automated process bringing them in to The Teletext Archive, currently at the rate of two per night. So there will be at least two new services a day going forward!

QTeletextMaker v0.7-beta released. The Level 2.5 #teletext editor can now export your flashy masterpieces to animated GIFs so they can stay flashing! Grab a Windows .exe from the zip at github.com/gkthemac/QTe... (mind the SmartScreen warnings!) or compile the source on Linux with Qt 6 and CMake.

1/2 Now that BlueSky animates your own uploaded GIFs, a Level 2.5 #teletext tribute to one of the earliest internet memes from the year 2000. A website "Flash intro" that promised everything but delivered nothing. zombo.com is still there, updated to HTML5 but still with the original soundtrack.

Teletext with level 2.5 colours starts not looking like #teletext any more.

Teletextmas and a Level 2.5 New Year.

The #weeklyteletextart prompt this week was "spaceship". So here's a re-posting of a #teletext recreation of the final level of the shoot-em-up arcade game "Phoenix", featuring one of the first examples of an end-of-game boss.

QTeletextMaker v0.6.5-beta released. The Level 2.5 #teletext editor now has monochrome rendering modes so you can see what sixels are foreground and background. Grab a Windows .exe from the zip at github.com/gkthemac/QTe... (mind the SmartScreen warnings!) or compile the source on Linux with Qt 6.

Wall-to-wall Level 2 Jobfiinder action on this YouTube video! I wondered who made this, and it turns out to be ORACLE. I wonder if Level 2 formed part of their bid for the ITV teletext franchise starting in 1993? They certainly have the Level 2 skillz https://www.youtube.com/watch?v=tkKMjI-aZAs

Morning

I took too long starting my #WeeklyTeletextArt "pirates" image again so @jamienemeth.bsky.social beat me to my idea 😆 Since he already took the Ross Revenge, I figured I'd do the Mi Amigo instead 😁 (The radiating signals effect animates) #Teletext #RadioCaroline
