The safest option is probably to remove the battery and run the phone from a (well defined/build) external power source, e.g. like this: https://yaky.dev/2022-09-06-smartphone-without-battery/

Yes that's what I do too! I didn't know that blogpost but I generally replace the battery with a DC-DC converter module from Ali. You can even tune the voltage and see the indicator change the battery charge level. I put them around 4 volt. The advantage of these modules is also that you don't need a beefy 5V power supply, you can simply grab a 12V or so (I have a full drawer of those from shucking external hard drives) and it will regulate it down nicely. They are 80 cents a piece (10 for 8 euro): https://es.aliexpress.com/item/1005007508685885.html and they can deliver up to 3A or so which is enough to handle the peaks. They're a bit bulky but I just tend to mount them elsewhere. Make sure you use a fairly thick cable to the phone then to minimise losses at that low voltage.

I didn't have to bother with the thermistor but some models need it yes. And some even have an i2c charge level module which is even harder to simulate though it can be done.

By the way the diode option is a decent one too, I went for this option because I had many 12V PSUs around, and due to the efficiency of the converter I can use ones with pretty low amperage. But if you have a decent 5V supply using a simple diode drop is not a bad option.

What is bad is using a resistor as the voltage drop will depend on the current being drawn by the device, but the article is not doing that (nor woudl I).

The link provided by cydodon is about emulating a battery.

From their website yseq.net:

- Whole genome sequencing ultra plus (150 Gbases raw data) is €699,- incl. shipping for the sampling kit

- "The turnaround time is approx. 5-7 months at the moment."

700 EUR doesn't seem like expensive for what it is.

For 200PB one would need 25kg worth of 2TB microSD cards... that would be lots of Rubik's cubes =P

Since I am working in the XRD/XRF/XAS space, what are the multimodal techniques that you see as the most beneficial ones to complement the x-ray measurements? If you can tell, I would also be interested what your field of research is :)

My field of research is whatever catches my fancy.

I do Aerospace as my current profession.

I just like to hunt for rocks and Caltech loves having me along because I get them stuff they normally don't get.

That is the advantage of the size! There is little chance you will forget that you have the device in your pocket =P

EUMEL maybe? https://6xq.net/eumel/ (Z80, M68000 and later x86 as well)

I know, that this doesn't help really, but in plasma physics as well as when dealing with degenerate matter and such 8 and 3 are the same number. Most of the time a scientist in these fields is happy to get the order of magnitude right! ;P

A preprint will still give less value to the negative result. No peer review (being a broken system or not) and not being published in a "proper" journal will make it less likely that the results will be recognised / accepted. The whole point is, that a negative result can have as much value as a positive one...

Why was this comment flagged, it's reasonable?

well... it's not always night time... it's not always clear skies.. it's not often that a power outage happens in my city to actually see the stars...

If measurement of the soul's weight gave 21, that can only be half of the answer[0], right?
