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.
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.
mikeselectricstuff on YouTube did a teardown on the Omnipod wearable pump a while back, very cool mechanism.

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.
I dont want CT scans of wearables. I want wearables that can do CT scans.
Is it just me or did the tonality in this one change towards an infomercial?
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?
still not into scroll-jacking, but these breakdowns were well-written and documented.
Great images, OK writeup. There are some bits of bullshit, like "The proximity of microphones to processing hardware minimizes latency". No, the speed of electrical signal propagation (around 2/3 the speed of light) is not significant for microphone placement.
It's AI slop. The descriptions are all meaninglessly specific like that, saying things that are technically true but don't make sense to point out.
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. ;)

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.

It's sad to see such waste with the Dexcom. A sizeable, single-use coin cell with a total useful life of 15 days, after which the entire unit is discarded.
These are largely somewhat pretty but ultimate unrepairable e-waste.
Sad to see the quality of the content from Lumafield slowly going down. Feels like the content got less technical after they moved it from "scan of the month" to their blog, and now it feels like the descriptions are just slop, not matching the scans themselves.

Examples:

- Each window is sealed under a thin polymer layer, balancing optical clarity with biocompatibility while preserving the ring’s continuous, scratch-resistant exterior. <- they're on the interior of the ring, and I'm assuming if they're polymer, they're not very scratch resistant.

- This flexible board architecture allows the Oura Ring to maintain its circular form as well as distribute heat [...] <- what heat? And how?

- The charging coil runs along the ring’s outer circumference [...] <- scan shows a small coil on the inside, not running along the circumference

- [...] we can easily visualize the deployment channel and insertion mechanism that guide this filament to its precise depth and angle. <- I can't see the insertion mechanism.

- spiral geometry <- the Bluetooth antenna isn't spiral. Nor does it communicate "through the user's skin"?

- miniature microphones (visible as small cylindrical cavities) <- they're rectangular.

It blows my mind they used AI to generate a couple paragraphs worth of rather nonsensical text. It would've taken them about as much time to just write something sensible by hand.
