Have stuck the FPGA Video Experimenter Card in the crate for a bit. It's taking serial in, drawing circles on the live video, and outputting as analogue. Already identified a few more issues that will need to be rectified in upcoming versions. Not least that the LEDs on the board are too bright.

Standard reminder that the BBC's linear channels are in fact "digital", have been entirely since 2012, and lots of money was spent telling audiences this.

The Video Experimenter Card continues to become more ugly - but also continues to yield promising results, exciting rabbit holes, and additions to the infinite Projects List.

Top down view of a PCB, which is bristling with bodged-on components and modules. It has a Tang Nano 9K FPGA on board, along with an ESP32 devkit, and another red PCB marked "SDI Deserialiser". It features multiple BNC sockets and blinkenlights.

An NMS logo, stylised like the BBC's 90s logo, takes centre stage - with the words "Video Experimenter's Card" below it.

Very quick demo of a Frozen Picture Alarm I am developing with my FPGA experimenter board. It performs a running average of the Luma and compares it with previous fields. If it hasn't changed enough it will increment the green bar. Once full this can give an alarm, for example.

This, incidentally, is why I get grumpy when people say various things about TX errors: SOMEONE ON SOCIAL MEDIA: "What a stupid mistake, they don't care about the output any more!" REAL LIFE: That error is the subject of a report which is still being updated a year or more after it happened.

I feel this is a particularly grim example of the traditional shocked face YouTube thumbnail. Go and stick your head down the nearest toilet, the pair of you.

🟦 CLEAN FEED | The late BBC One news will certainly be late tonight because of a certain football match. EPG data currently suggesting 11.30pm start but likely to be later than that.

Isn't this crazy. 5000+ views on Pages From Ceefax in just the past 48 hours. I wonder how many watch "This Is BBC Two" these nights...

My latest addition to the FPGA Video Bodge Board is an SDI Deserialiser. Haven't done anything terribly exciting just yet but it does mean one can draw stuff onto live video and output as analogue, etc. Next I'll have to design a Serialiser!

I have zero interest in Football but I fully support bringing a Vulcan & a few Harriers out to the England v. Argentina match. You know. Just as a reminder...

I am looking for good quality SDV->CVBS and CVBS->SDV cards - I have looked for Vistek, Crystal Vision, Nevion and Evertz crates and I can find one or two crates/cards of each... I really don't want to end up with forty different incompatible crates/cards - if you happen to have one please shout!

First world problem here right, why does Ubereats make you decide on a tip to leave before you even place the order. You know? Like if I'd known you were going to piss around for 40 minutes and then deliver my chips cold and ice cream melted, it hardly deserves an extra few quid for a good job?
