Insulin is incredibly potent and can easily result in life-altering if not fatal consequences at relatively low ratios of the therapeutic dose, so these things need to be dialed in and extremely reliable.

YouTube teardowns from knowledgeable engineers are a gold mine for learning how real world products are engineered. I always recommend these for early career hardware students and engineers.

The entire library of scans on this site is great. It gives me a similar feeling as being a kid and playing around in 'The Way Things Work'[0].
The custom Lipo battery with thermal effects and weight considered is really beautiful to see. I've been curious about custom Lipo battery shapes for rings because my fingers get cold when I wear rings. Would a battery heating up just a bit help make that comfortable for me?

In something ring-sized? Maybe for about five minutes, and then the battery dies. (I assume you mean using resistive elements to create heat; heating the actual battery seems like a bad idea.)

Unless the ring is shaped as a heatsink/radiator, I imagine it would eventually get into equilibrium, and you wouldn't feel the heat-flux.
Is it possible that the "coldness" comes from its indirect affect on blood-circulation?

Really love these scans! I would love to have on of these at home, just to tinker with devices and understand how they work.
Then I usually want to check the price, see "Talk to sales" an decide probably not the price range that is good for private use.
Nonetheless, great articles and an amazing device.

I’m sure there’s the small issue of radiological safety as well. Obviously one can be trained to not fry yourself with x-rays, but I wouldn’t, say, pick one up off Aliexpress and have at it.

Glad they're still doing these. I really enjoyed Scan of the Month and then they just stopped doing new scans after the Moka Pot.

I dont want CT scans of wearables. I want wearables that can do CT scans.

That is not even close to feasible with today's level of technology, and will not be for quite some time.

well, maybe wearables that provide some sort of internal visual scans. But with CT scans delivering 70 times the radiation of a typical x-ray, I think I'd prefer not wearing a portable chernobyl.
Maybe a wearable ultrasound instead?
edit: after a little informal side-searching after posting this, I've learned that people working at Chernobyl, not in the reactor directly, but elsewhere in the sprawling site received anywhere from 1 to 100 CT scans worth of radiation. The firefighters that were on the roof received anywhere from 100 to 1,600 CT scans worth of radiation.

If one is concerned about the potentially damaging effects of radiation, and the relative safety of ultrasound technology springs to mind, then one may be also interested in reading more about the apparently forbidden topic of ultrasound safety studies, if such a person can get past the cognitive dissonance from having been told the consensus opinion on how safe ultrasound is, e.g.:
I personally prefer to approach the topic of "safety" by considering the trade-offs. The knowledge gained through ultrasound significantly outweighs potential risks associated with it.
People still continue to play the lotto thinking they will win, and they reject statistically low risks in lieu of a greater risk created by avoidance. See: any vaccination topic.
When shifting into the topic of a wearable though, the extreme amount of time alone amplifies the risks into outright dangerous levels. I did not seriously believe ultrasound to be safe to that level.

All of those links are for the same book from 2015 (the fourth isn't direct to the relevant article but it's easy to find on the page). Has there been any new information since then?

The 50 studies in the cited 2015 book ought to span a range of time, and their keywords could be used to search literature for more recent material.
> Has there been any new information since then?
Since you asked, there apparently was a 2017 followup book by the same author. These links are for that book:
