Rare Filament Makes Weird Benchies

https://invidious.privacyredirect.com/watch?v=J8PZWkjt65Q

[Zack], in addition to being a snappy dresser, has a thing for strange 3D printing filament. How strange? Well, in a recent video, he looks at filaments that require 445 C. Even the build plate has to be super hot. He also looks at filament that seems like iron, one that makes you think it is rubber, and a bunch of others.

As you might expect, he’s not using a conventional 3D printer. Although you might be able to get your more conventional printer to handle some of these, especially with some hacking. There is filament with carbon fiber, glass fiber,...

How to silence the fan on a CM5 after shutdown

How to silence the fan on a CM5 after shutdown

Out of the box, if you buy a Raspberry Pi Compute Module 5, install it on the official CM5 IO Board, and install a fan on it (e.g. my current favorite, the EDAtec CM5 Active Cooler), you'll notice the fan ramps up to 100% speed after you shut down the Pi.

That's not fun, since at least for a couple of my CM5s, they are more often powered down than running, creating a slight cacophany!

Arduino-programmable environmental and air quality sensor kit features ENS160 and BME280 sensors

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display Module.
