I’m not sure I understand this. Small scale fluctuations are the easiest things to achieve, in fact they occur spontaneously. It’s the large scale fluctuations that would be difficult to achieve.
For example if you have a room filled with air, then changing the temperature of all the air in the room would require doing a lot of work or transferring a lot of heat to the entire room. But on the microscale, if you were to look at a random 1 micrometer cube volume of the air, then you should expect temperature fluctuations to occur all the time, even without the addition of heat or work to the room.
It’s like staring at static on a tv screen. The overall shade of the entire screen is middle gray and over time stays gray, but unsurprisingly individual pixels will fluctuate randomly between pure black and pure white. Small scale fluctuations occur spontaneously.
Well think about this, are you able to manipulate temperature within one degree? Sure. Get a stove. How about one one millionth of a degree? Is that easy to achieve? Its not. Same on a cosmic scale, changing things by one million degrees? Easy as pie, one degree? No way. Sure, you have done it a million times to get to a million degrees but you didn’t do it with precision.
That’s what I think is amazing, our precision only capable at this level because of our size and capability in this universe
My mistake with the wording, I will say though infrared light raspberry pi or no, still would not be enough for that. You need serious lab equipment. Like advanced cooling methods to achieve this sort of thing. That’s why I chose this range. With your method I could see possibly being able to do a percentage of a degree in keeping it stable with no outside forces, but accuracy within a millionth I think is a stretch

Alright so you want to cool something down to an absolute temperature that is in the micro kelvin? Yeah, that’s is going to be hard.
But you could just go from 300.000001K to 300.000002K for example, no super cooling required. So far your wording only implied a change, no absolute values. Otherwise it would also be pretty hard to get to 1K for your one degree example.

Yeah ok, if want to keep an object at an exact temperature with that precision, you’ll need some additional stuff. But I don’t think you’ll need a top tier lab for that. A vacuum chamber with the test object, an array of infrared lasers suspended inside and a bit of electronics in a temperature controlled room should give some good results.
A millionth isn’t that small though, but it will get impractical if you go even smaller.

Get an infrared lamp and do some maths … about the same difficulty I’d say.
My man… You cannot achieve temperature stability within accuracy of a micro kelvin with “an infrared lamp and some maths”
You were just saying “manipulate” temperature so far, but ok. If you want temperature stability you’ll also need a raspberry pi.
