Fish-inspired filter removes 99% of microplastics from washing machine wastewater
Wastewater from washing machines is considered a major source of microplastics—tiny plastic particles that are suspected of harming human and animal health. Researchers at the University of Bonn have now developed a filter to curb this problem. Their invention was inspired by the gill arch system in fish.

Mikroplastik mindert die CO2-Aufnahme der Meere
Forschende warnen: Mikroplastik schwächt die Fähigkeit des Ozeans, die Temperatur der Erde zu regulieren und weltweit das Klima zu stabilisieren.

In my #HamRadio #POTA adventure today, I got my inverted-V linked dipole caught in twigs today and it died. The silicon wire winds easily around a tight radius, which is nice for putting it on the winder, but also winds around twigs easily, and that fine wire breaks easily. Easier than…

Another threat to reefs: Microplastic chemicals may harm coral reproduction
As the sliver of a new moon shines over Kāneʻohe Bay, Oʻahu, millions of tiny orbs ascend from a reef and swirl in the water column. These spheres are bundles of coral eggs and sperm responding to lunar cycles and chemical cues in the water that tell them when to fertilize and where to settle […]

Over the past couple weeks, I've been designing a spool with some particular features in #FreeCAD, encompassing 6 parts to 3d-print. I've been manually re-orienting them when I print them.
Now that it's working, I realized that I could use the FreeCAD Assembly workbench to create a good packing of the parts in the right orientation for printing, saving anyone else who wants to prin…

I packed for #POTA before heading out to do the weekly grocery shopping, even though it was only 40°F / 4.5°C with low clouds. I decided it was too cold to sit in the helinox chair without insulation, so I drove past US-3867 and went to US-2755 Umstead State Park instead, where I could sit at a picnic table. I took a floor mat out of my car to sit on. As it was, it was cold enough that I co…

I made a #HamRadio antenna that I really like, and wanted to share the design and process so others can do it too. It's a carefully-tuned linked dipole that is light and has served me well for #POTA activations. It's now in its second iteration and so far I'm very happy with it.
