Bogus 1080p/60 USB 3.0* HDMI Capture Card (Linux) by Linux Game Cast (youtube.com)
Can you get 1080p/60 HDMI capture for under $20? The LYLEE Upgraded Video Capture Card seems to think it's possible. After contacting both Amazon and the seller the item went POOF! We might have accidentally did a good :D/

Meh… that’s exactly the HDMI capture I got months ago. I needed it mostly to debug some Raspberry boot trouble that would show way too short to be parsed by a human before the device would reboot again so it’s okay. I did wonder though why the framerate was so jacked up but blamed the undervolted HDMI splitter (It came without a fitting PS so I’m happy that it does _something_).

Lesson learnt. I suspect similar for a dead cheap SD-card writer at work.

I’m having way too much fun with this. Did some plumbing today and this is the result 😀

The flight instruments are from https://github.com/uw-ray/Skyhawk-Flight-Instruments and are not for obviously.

I patched the http server to send Access-Control-Allow-Origin so the browser wouldn’t refuse to load. Could set up a proxy but I wanted results fast xD

  • Speed is also mapped to ALT as Fast Travel speed
  • It reads just the camera position and not really the ship position (and since there is no up and down in space it settles fast on the new artificial horizon – may need some more tuning)
  • Plumbed the speed to the pressure so it starts creeping up from 27.1 inHg to 33 inHg (max on the instrument) when speed goes over 200. Just for fun.
  • Turn Coordinator is just Camera yaw + left or right based on mouse/pointer X.
  • Some target data as proof of concept

This worked out better than expected and the best thing is: Doesn’t need to run on the same computer – it just has to be on the net so a tiny Raspberry and some external display would be enough for some fun cockpit building 8)

Not a big fan of reveal parties n stuff so here goes what some close friends know already:

If I had just one wish
Only one demand
I hope he’s not like me
I hope he understands Creed, With Arms Wide Open

(I’m bad with words)

The little one (7) saved for a new toy camera. After doodling around with the camera she mentioned wanting to make “movies” so I gave her a little tripod and suggested to go for a Stop Motion one. She listened to the overall idea and vanished in her room. A day later I was presented with a SD card full with over 300 pictures of one scene each carefully adjusted over the course of three hours.

I’ve to say I am really impressed with what she achieved here on her own just by listening to some ramblings of mine and fiddling with that toy camera, that sadly is not even able to write legit JPG images so they couldn’t be used as input for ffmpeg to make a movie out of the sequence. ImageMagick had my back though converting the faulty images to PNG and with two lines of console commands we managed to produce a movie she can proudly show her friends now:

mogrify -format png *.jpg
ffmpeg -framerate 5 -pattern_type glob -i 'PICT0*.png'  output.mp4

Of course she asked for an audio / voice-over next. Should have seen that one coming xD

Misinformation about Permissions Policy and FLoC by Rohan KumarRohan Kumar (seirdy.one)
This post was written in a hurry in response to some misinformation about Google’s newest Web antifeature, Federated Learning of Cohorts (FLoC). Google’s FLoC is an attempt to track users even when their browsers (rightly) block third-party cookies. The initial blog posts about this issue were q...

Who would have guessed: That empty policy header against FLoC is probably worthless in the first place because people that are concerned about this are probably not affected by a prior opt-in at all: https://seirdy.one/2021/04/16/permissions-policy-floc-misinfo.html

Really curious what else will show up on this topic over the next weeks.
