But if someone doesn't want to send the GP2X but can provide x-ray's; that would be great to ;) I lack both btw :(

A long time ago I implemented a void pointer array in C for an embedded OS, which was a hassle. While I like you knew what was happening and solving a technical challenge, the modern programming languages make life much easier.

Sounds like an idea that will end up in the storage of some medical company that purchased the rights to this solution.

James Earl Jones, known from the voice of Darth Vader and Mufasa (in the original Lion King movie), has passed away. https://www.theguardian.com/film/article/2024/sep/09/james-earl-jones-dies

Smart move by Nickelback: If you don't listen to Nickelback you might be called a Trump supporter :confused: https://intellectdiscover.com/content/journals/10.1386/mms.2.1.39_1

The Frore airjet is decribed to remove warm air on top of the chip which regular fans need to move more air for to achieve: "The internal piezoelectric membrane vibrates at 24 kHz, and pulls air in from the top of the device, disrupting the "boundary layer" of hot air above the chip being cooled...

Next to the Frore mems cooler we now also have the even smaller micro-cooler. It's a tiny chip which can be used as a fan in mobile devices. https://xmems.com/products/microcooling/

By November of 1923, the currency would depreciate to 4,200,000,000,000 marks to one US dollar -the internet

That's rediculous! For that amount I could get you 10 of those :)

That answers the battery charging mystery :cool: So if you don't have the LTE version you should be able to charge to the full 100% ?

Did you spot any significant temperature diiferences?

If you find the lowest voltage per frequency for the reference Pyra you have a reference voltage curve. If you do it for a few more you can see the deviation. I would assume a Pyra that has a higher or lower voltage will show the same over the complete curve. So by doing one measurement you...

I can imagine the voltage requirements are higher when under full load. A boot sequence might be enough for testing this, but you might want to have a short load-test to have the CPU/RAM/Disk to be utilized at the same time if a boot isn't doing this already. When finding a stable value you...

I guess it was too much scrolling/searching? I like granular frequency selection; so you can select the highest value stable for your Pyra. Is 50MHz the smallest step we can use? Maybe smaller iterations in the top/max frequency would be nice, while we have larger steps at the bottom.

I could imagine RTC was designed into the product at one point but wasn't important enough compared to battery life or cost. So it was removed again.

It was an example, there are many RTC modules available. If you want to use UART it exists also. @Orkie did anyone attempt this mod before? I can understand soldering directly to the board might feel risky compared to an external add-on.
