It's always interesting to see how are things build in the Lumafields "Scan of the month". The the most interesting scan from Lumafield I saw was not a Scan of the month, but in "Adam Savage’s Tested: Surprising Flaws in 18650 Lithium-Ion Batteries" [1]

PS: Nice company logo btw. ;)

mikeselectricstuff on YouTube did a teardown on the Omnipod wearable pump a while back, very cool mechanism. https://www.youtube.com/watch?v=e2MQUUkubgs 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.

A friend's coworker had their pump lock on, and inject the entire reservoir of insulin into them. They were discovered in their home by the police after family members lost contact. No idea if it was an Omnipod, but I would hope that all insulin pumps have a separate watchdog circuit to prevent this.

San Diego is really a hub for health wearables! Tijuana to an extent too. Oura - based in SD. Dexcomm - based in SD. Omnipod/Insulet - major R&D hub in SD & TJ.

Oura is headquartered in Oulu Finland and the main US office is in SF.

San Diego does have a bunch of health tech, but it pales in comparison to Boston.

I don't have firm data on this, but colloquially among medical people, San Diego is seen to have more biotech startups than any other metro, including Boston/SF.

Boston has more research, of course, though SD is competitive there as well.

We can disagree about numbers etc, but 'pales' doesn't reflect reality.

Did they survive?

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?

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.)

My bad, I read the article wrong, they are only concerned with thermal heating while it's charging. I did seem unexpected that a ring could heat up enough to be a concern while being worn.

A battery. Which can catch fire. Around your finger?

Phones catch fire and men tend to stick them in the front pant pocket. But yes true, so far I haven't gotten into smart jewelry. I was pretty into jewelry for a while but never rings because of the cold finger situation. Necklaces can be problematic too. I chipped my front tooth slightly when I jumped wearing a big crystal and smacked myself in the face with it.

> my fingers get cold when I wear rings 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?

Yes I think you are right and also fingers tend to swell and shrink with heat and cold so the ring that fits nicely in a cooler room will restrict circulation slightly once I'm feeling warmer, leaving me with one cold ring wearing finger.

Earlier quoted context omitted.

That book claims: > Microcephaly incidence increased 1000x within the area of The Network. This was first observed seven months after The Network began its remote prenatal ultrasound program. Do the math. Almost every baby is exposed to prenatal ultrasound. What do you think was different about that ultrasound program? Why would prenatal ultrasound cause microencephaly there, but not everywhere?

> not everywhere? Are you absolutely certain that there is not an unexplained uptick in brain damaged newborns/children in the USA? And that its cause is not some thing(s) that "almost every" one of them is subjected to repeatedly? And that it is not just a case of better/more/over diagnosis? IDK about by you, but there are literal nurseries/schools for the brain-damaged kids popping up on Main Street. That's how man…

I don't think that's comparable to what happened in Brazil at that time.
