Not one of the adjectives I would use to describe pizza.

Reading a book titled 'Schlieren Methods' and learning about the quantitative applications.
Sadly I cannot find the the mentioned publication my Maksutov. I'd like to know how big that mercury mirror was.
In the same book a method for a large-screen projection system is described. An electron beam charges an oil film whereby its changed reflection produces bright and dark regions in a schlieren setup... What a wonderfully convoluted way to produce an image!
A friend (sadly not on Mastodon) at the FabLab crafted this masterpiece with a photocopier and a smol blahaj.
Now with USB3 and 5000fps!
As the sensor doesn't output usable data in the first line of the image I used the space to include metadata. The first 32 pixels contain a framecounter, the next 32 a microsecond timestamp. The remaining 16bit are user programmable, but I might replace that with the exposure time in microseconds.
Above 5kfps I get recording errors despite the datarate being only ~0.35Gbps. But I don't know the cause of the problem yet.
And another one of those government drones captured in slow motion!
Switched to a different objective and got this amazing shot of a pigeon starting!
(1000 fps -> 25fps)
A lighter being lit, recorded at 2000 fps, played back at 25 fps.
Mastodon won't accept the video directly, so I had to convert to GIF, which introduced the dithering.
I'll try to find a better way to convert...
I finally got the data transfer from the AISC110C high-speed camera sensor working!
It's a 5€ chip that outputs 80x120 video at up to 40k fps.
Data is read with a Xilinx Spartan7 and transmitted via USB3 with a Cypress FX3, each on its own little PCB.
The front PCB is exchangeable, making this a neat modular platform. I already have an analog video frontend with the ADV7182 and am working on a Cameralink interface.
Videos are coming tomorrow, I need more light for the high framerates.
Here's a photo of the back with the safety pin. The solder stuck really well to both the silver and the nickel (as was to be expected). The big fillet hopefully provides the necessary stability.
