3 kid-friendly STEAM electronics projects that harness NOAA’s massive public databases

This is the winter of finding as many good, educational projects to keep our kids as occupied as possible. If you’re anything like me, you probably have a stack of assorted electronics in various stages of disrepair, which is great for your hardware hacking dads and moms, but kids need projects with a little more structure and, especially for the younger ones, a lot less soldering.

We can’t build open-source CTDs every day.

Fortunately, the awesome folks at Adafruit have built up an absolutely massive collection of electronics projects using just about every component you can imagine. I’ve culled through the archive to find three kid-friendly (projects that don’t require soldering or involve particularly risky components) ocean and weather projects that take advantage of NOAA’s publicly available databases to help students learn a little bit about electronics and the natural world.

All of these projects were built with the help of my kiddo (age four), require no soldering or electronics skills to start, involve just enough coding to stay interesting, and use Adafruit’s CircuitPython ecosystem, which is fairly easy to learn. Adafruit does a great job compiling detailed instruction for every project. These can all be completed in a lazy afternoon.

Hot air for windmills, oceans get layered, and North Korean ghost ships – What’s up with the Oceans this Week

September 30, 2020September 30, 2020 Andrew Thaler

News

Nothing but hot air. Trump bans windmills. The President made bemused news last week during his oddly partisan attempt to ban offshore oil in several key states (though for some reason, seismic testing in those states continue, making it seem less like a ban and more like a request to “stand by”). Unsurprisingly, the offshore … Read More “Hot air for windmills, oceans get layered, and North Korean ghost ships – What’s up with the Oceans this Week” »

Tear gassing fish, new NOAA chief, and Facebook’s flop – What’s Up With the Oceans this Week?

Tear gas is bad for fish. Surprising no one, if you unlawfully unload tons of tear gas into a peaceful crowd of protestors in order to create chaos as a precedent for state violence, that tear gas will eventually find its way into drains and all drains lead to the ocean. And that is bad … Read More “Tear gassing fish, new NOAA chief, and Facebook’s flop – What’s Up With the Oceans this Week?” »

How anglerfish hack their immune system to hang on to a mate

When you live in the darkness of the abyss, finding a partner is hard and keeping a partner is even harder. Deep-sea anglerfish, one of the iconic ambassador species of the deep ocean, have found a novel solution to this problem–dwarf males are sexual parasites that latch onto the body of the much larger female anglerfish and then physically fuse to their partner, becoming permanently attached to the point where they share a circulatory and digestive system.

Parasitic dwarf males are uncommon, but not unheard of, throughout the animal kingdom. Osedax, the deep sea bone eating worm, also maintains a harem of dwarf males in a specialized chamber in their trunk. But few species, and no other vertebrates, go to quite the extremes of the anglerfish. And with good reason.

Vertebrate immune systems have a long shared history. The Major Histocompatibility Complex (MHC) is a suite of genes shared among all gnathostomes–the taxonomic group that contains all jawed vertebrates, from fish to fishermen. It creates the proteins which provide the foundation for the adaptive immune system, the core complex which allows bodies to tell self from no-self, detect pathogens, and reject non-self invaders. Suppressing the MHC seriously inhibits a vertebrate’s ability to fight off infection.

Incidentally, not all deep-sea anglerfish have parasitic dwarf males, and the species most often presented as a type specimen in the popular press, the humpback anglerfish Melanocetus johnsonii, is one of several that do not have permanently attached parasitic dwarf males. M. johnsonii males are free-swimming throughout their life, they’re just small and clingy.

Denial Incorporated. Over the weekend, the Administration announced the appointment of David Legates, an anti-science activist embedded in the climate denial industry. Legates will answer directly to acting NOAA administrator Neil Jacobs. Expect to see Legates making the media rounds downplaying the impact of climate change on the occurrence of more frequent and powerful tropical … Read More “The climate denial industry in full swing, 5 storms rage across the Atlantic, and Orcas seek vengeance – What’s up with the Oceans this week?” »

Frisky business for Great White Sharks. For only the second time since western scientists began studying the ocean, Great White Shark mating has been documented in the wild. Shark sex is infrequently observed in the wild, and this fisherman’s observations can provide invaluable insight in the lives and loves of this iconic species.

For over 50 years, deep-ocean explorers have been able to claim that more people have walked on the moon than have dived to the deepest point on the Earth. Only two men descended into Challenger Deep in the 20th century–Don Walsh and Jacques Piccard–they were joined in the early 2010s by director James Cameron. Earlier this year, Victor Vescovo became the fourth to reach the bottom of Challenger Deep and, over the course of several subsequent dives this summer, the ranks of those who’ve reached the deepest ocean has swelled.

Astronaut, oceanographer, and former NOAA Administrator Kathy Sullivan and explorer and mountaineer Vanessa O’Brien became the first and second woman to dive to the bottom of Challenge Deep aboard the privately owned HOV Limiting Factor, piloted by Vescovo and his team.
