Biodegradable electronics can break down into harmful microplastics
Northeastern University researchers have discovered that materials used in the development of transient electronics—devices designed to biodegrade at the end of their life—can break down into microplastics, casting doubt on the true dissolvability of these devices over time.

Scientists trace microplastics in fertilizer from fields to the beach
Researchers from Tokyo Metropolitan University have studied how polymer-coated fertilizer (PCF) applied to fields ends up on beaches and in the sea. They studied PCF deposits on beaches around Japan, finding that only 0.2% of used PCFs are washed into rivers and returned to the coastline. When there are canals connecting fields to the sea, this rises to 28%.

There are just too many patents granted. Example 33,444,592: This company literally sticks a microwave oven on top of a fridge and gets a #patent for that.

To replace my lightweight linked dipole antenna for #POTA I am iterating on a #FreeCAD design for a winder that works with wire that shouldn't be bent sharply around the edges of a more typical winder.
This design allows either figure-eight or circular winding with a minimum repea…

I finished "The Dig" after about 12 hours of playtime. I liked it, but it's a strange entry to the LucasArts canon: it has traditional VGA pixel art for most of the game with some sudden cel…

La géopolitique des microprocesseurs : une leçon cruelle pour les Européens
La production de masse de puces incarne un hypercapitalisme extrêmement gourmand en investissements, en recherche et développement et en énergie, dans lequel l’Europe n’a pas encore trouvé les moyens de rivaliser.

This descent into capitalism by Arduino is so upsetting. Are there alternatives?

My #HamRadio #POTA fun today was activating US-1904 Myakka River State Park on 20m and 17m, with 5W CW, on my new edition o…

Going on a journey on Germany‘s known to be unreliable trains. Everything‘s going great and on time so far!
Teenagers are shouting Six Seven and I just saw a lone construction trailer in the middle of a field with several dozen chickens around it.
