Imagine writing the headline here and it still occurring regularly over thirty years after the demise of your platform.

this was clearly a joke but amusingly I see there are a few more viewers than usual at the moment...

Obviously what this means is I need to build a rediculously complicated and over-engineered backup UPS and generator system to keep Ceefax on air in all eventualities. (*JOKE* donate to my KoFi!)

Rolling news is not news. Itโ€™s a reimagining of baseless speculation at best half the time.

Found this rather homebrew looking "test sig gen". Produces bars with static caption as shown. Last test sticker from 1996. (what's that, 30 years!?)

I put together a demo with an ESP32 writing text (milliseconds since startup) to my FPGA. So I've sort of made a graphics card...? The counting up reminds me the BIOS RAM test you used to see on PCs.

This is a different FPGA Experimenter card from the one you saw before. This one doesn't have an SDI Deserialiser and as such commits fewer crimes against high speed digits. Instead it has an SPI, which copes up to about 80mbps before it gets (very) upset...

BREAKING: The White House TV Press pool is downing tools following Trump's ouster of Politico, MSNOW and CNN. This letter sent to pool members by Fox News' Washington Bureau Chief Bryan Boughton, current pool chair, via Scott Nover of the Washington Post.

FPGA based text overlay. Bonus points to those who guess who's post I copied the test text from, for no particular reason.

Messy rack pics again but this is the FPGA taking SDI, creating a 'scope view & outputting as PAL for the left monitor, with the right showing a preview. You can see the FPGA card in the frame, towards the middle with the front entry BNC. Ignore the dangly networks they are necessary & unmovable..

They multipliest. Crazy how cheap these can be acquired without PSUs. Is the overlap of "people who need a vision mixer" and "people who can solder a plug onto a PSU" really so small?

Someone should do a modern take on that 70s "day in the life of TV" programme. A clip from all the different job roles in a regional studio should make a pretty interesting programme - and even fits with the latest fad of remaking stuff...

iPlayer asking me, twice, if I've got a TV license - when I'm signing in from *inside the BBC* - will never not be funny

I also realise that mis-spelling "licence" on a post that includes it twice in screenshots is not a good look for me.

Comparing my rasteriser to a real scope. Mine isn't doing the clever maths required to low-pass the samples to Nyquist and keep them sine-looking. Still cool though...

OK fine, fine, I couldn't let it rest - here are the dots joined up in the appropriate fashion.

Tonight's FPGA experiment is an SDI scope. This is the luma bit of a staircase. The grey line shows what line in the picture is presently selected.
