I have an HDMI switch that starts acting up if the power cable gets loose. Why does the power cable get loose? No idea, but it’s also a cheap nobrand switch. This probably isn’t your issue, but try pushing the barrel connector in more or try a power supply that supports a higher current (same output voltage). I only mention it because I only managed to “fix” my switch by noticing it was just a mm out of the jack.

I’m assuming if the syringe was wet before being placed in the microscope, the vacuum of the chamber would cause most of the water in the plasma to vaporize. The remaining salts and compounds would be much smaller than the red blood cells. The density of the red blood cells would be much larger than any remaining plasma, so the bulk of your backscattered electrons will be coming from the cells and needle, making the plasma essentially transparent. This is a fairly low magnification image for SEM, but that’s how you get such fantastic depth of field.

This is great! If I ever get a minute from playing Balatro from the Steam sale I’ll try some out!

I saw this a bit ago and I think it’s really creative. I won’t use it though because I’m not a cat person. If there are any other unique ones out there (not just a distro logo with flair), I’d be interested.
