The company behind these scans is <a href="https://www.lumafield.com/" rel="nofollow">https://www.lumafield.com/</a> - a really cool way to do marketing for your product. Love it!
Pairs nicely with this great book about all kinds of electronic components -- <a href="https://nostarch.com/open-circuits" rel="nofollow">https://nostarch.com/open-circuits</a>
What a great concept for explaining the inner workings of everyday things. From a product perspective, what a dream to have that available to take the mystery out of what you do. I'm thinking of other hidden mechanisms that people use every day that it would be socially helpful to understand, and the sponsorship ops must be amazing. I suppose there's just some people you can't convince, so a 5G transmitter might not be a great example, but maybe a speed enforcement gun, the secure element on an iphone, SIM, or chip and pin card, the brake caliper of a car with regenerative braking, a high end espresso machine, a top tier audio amplifier, etc.
> <i>We used the measuring tools in our Voyager analysis software to decode the model number: it seems to mean that the battery is 21mm in diameter and 70mm tall.</i><p>Or they could just read <a href="https://en.wikipedia.org/wiki/Battery_nomenclature" rel="nofollow">https://en.wikipedia.org/wiki/Battery_nomenclature</a>, which describes the relevant IEC standard.
The Tesla 2170 cell has a big hole down the middle of it...<p>That seems like a missed opportunity for a watercooling pipe, or anything else to use that space effectively.
I have some LiFePO4 batteries powering my laptop, and onboard electronics on my boat. They are very heavy, but have a super long life. Often forgotten, they are used a lot in automotive applications!

Very interesting!<p>Confused by the text about the alkaline scan (the first one). The +ve side is called the anode isn’t it, not the cathode? And electrons originate at the cathode not the anode. Or is the usual terminology inverted because it’s a battery or this particular type of battery? I don’t know much about batteries; chemistry never a strong suit.
>> Create an account and continue browsing on a computer to experience the demo assets.<p>Super cool, but requires account to check out a scan-which won’t work on mobile regardless, fyi.
How doable (guess not) would it be to make a "gravity battery" ? A tiny but heavy balls are thrown from top and while passing thru thin channels they rotate some sort of mini-dynamo that creates electricity. Once all balls are on the bottom, generated electricity is used to rotate the whole thing and start process anew.<p>Anyone with a napkin can elaborate why this is not feasable?
How are they getting color? My impression is CT scan is mostly measuring density and x-ray absorption. Are they doing false color based on some sort of data (vs photoshop?)
