Predicting the Future (Tides)

The beach outside our Whidbey place is amazing. There’s about twenty yards of firm sand and rocks along the shore, then a broad, flat, soft expanse of sand/mud/clay for just under 100 yards, then maybe 30 yards of firm sandbars. Beyond the sandbars, the channel drops to a depth of about 500 feet or so…

Anatomy of a SMART Health Card/Link Viewer

Over the last few months I’ve been working on a project with the good folks at TCP — the latest stopover on my long, painful, only-debatably-successful journey to use technology to benefit health and healthcare in the world. I’ve written about this project a few times already, and I continue to be excited about the…

Real-world IoT with LoRaWAN

Remote monitoring of a community water tank for under $500, that works kilometers away from wifi or cell service, incurs no monthly fees, and uses a battery that lasts up to ten years? The future is here! I’m super-impressed with LoRaWAN, The Things Network and my Milesight Sensor. Read on for all the nerdy goodness.…

Diceball, a Glowforge++ Project

Baseball, specifically Red Sox Baseball, was a Big Deal for kids growing up in the 1970s in suburban Boston. We all collected and traded cards, prayed to be put on the Red Sox for little league, kept score watching on channel 38, played home run derby on the neighborhood tennis court, and established infinitely complex…

Nerdsplaining: SMART Health Links

This is article three of a series of three. The first two are here and here. Last time here on the big show, we dug into SMART Health Cards — little bundles of health information that can be provably verified and easily shared using files or QR codes. SHCs are great technology and a building…

Nerdsplaining: SMART Health Cards

This is article two of a series of three. The first is here and the third is here. Last time I explained why I think SMART Health Cards are awesome. This time I’m just going to dig into how they work. To recap: a SMART Health Card (I’ll just call it a SHC from now…

SMART does it again with Health Cards and Links

This is article one of a series of three. Two is here; three is here! A few weeks ago I helped out with a demo at UCSD that showed patients checking into the doctor using a QR code. It was pretty cool and worked well, excepting some glare issues on the kiosk camera. But why,…

A Woman of No Importance

Appropriate for Memorial Day and the reflection it deserves. A Woman of No Importance by Sonia Purnell tells the story of SOE, OSS and CIA agent Virginia Hall, winner of the Distinguished Service Cross, the French Croix de Guerre, and the Most Excellent Order of the British Empire (man does that sound British) for her…

Bionic!

Last Tuesday I got up in the morning, showered and ate some breakfast, took the dog out, did the crossword, got a new pair of eyes, took a nap, watched the Mariners game and went to bed. In case you missed that, I got a new pair of eyes. OK, new lenses to be precise,…

Every Mistake

I’ve been working on myself for fifty-four years; software for about forty; kids for almost thirty; and (as Jim says) sawdust for six or so. Whatever the domain, sometimes projects go great and sometimes they, well, don’t. But it’s hard for me to think of anything I’ve tried — even the worst of them —…
