Right, the last article's gone live so it's time for my daily #Hackster round-up - and once again I've been a busy beaver, so if you don't want a ten-toot-thread in your timeline maybe put me on a timed mute... now.

Peter "Bobricius" Misenko's revisited the Armachat ESP32-based #Meshtastic messenger and PICOmputer #RaspberryPi Pico-powered portable ZX Spectrum emulator - creating "FLIP" variants with a clamshell design, like little mini laptops.
They're still using PCBs as a chassis, too. Sandwich-tastic!
Peter "Bobricius" Misenko Goes Clamshell for the New Armachat FLIP and PICOmputer FLIP
Tiny laptop-style machines offer your choice of Meshtastic mesh networking or Sinclair ZX Spectrum emulation in your pocket.

Back to #science now, and this one's... unexpected. Researchers have found a use for "detoxified" asbestos cement - yes, the wonder-material that we built everything out of before finding out exactly why we shouldn't have done that.
They're using it as an additive. For PLA. To feed into 3D printers.
The crazy part: if processed in the right way, it's not only safe but can reduce the temperature required for the PLA to biodegrade.
Researchers Find a Safe New Use for Dangerous Asbestos Cement: a 3D Printing Additive
Detoxified asbestos cement can be added to PLA and used for 3D printing, a team of researchers has found — and can even biodegrade.

Finally - *finally* - a work-in-progress project to build a microcontroller-powered "smartphone," which has already reached the functional prototype stage with voice calls, text messaging, data connectivity, and a working camera.
Oh, and it's 4G - which means it'll work even in places where they've already shuttered the 3G network most of these projects were based on. (The ones that aren't 2G, anyway.)
This Espressif ESP32-Powered 4G "Smartphone," Programmed in the Arduino IDE, Packs The Essentials
A proof-of-concept prototype ahead of a more svelte custom PCB, LuckyBor's microcontroller-powered featurephone can call, text, and snap.

More news out of #Arduino: Edge Impulse Studio is now fully integrated in the Arduino App Lab, the IDE that lets you write programs that can make use of both the application-class Linux-based and real-time microcontroller chips on the Arduino UNO Q.
For AI.
No, wait, come back! It's the good kind! Machine learning! You can use it to train machine learning models on your own ethically-sourced data and run them entirely on-device.
Arduino Brings Full Edge Impulse Integration to App Lab for Easier Machine Learning on the UNO Q
Arduino's first single-board computer in the UNO family now gets an easy way to train and deploy computer vision and other edge AI models.

@RueNahcMohr I'm sorry Dave, I'm afraid I can't do that.
Well, no, it definitely can. But it could also have a model trained to detect when the LED is blinking!
...if you wanted.

@ghalfacree if you know how to make these links work from the official Mastodon client on iOS when I have Lagrange installed, I’m all ears. Can’t even select the text to copy and paste and if I could, it cuts off the link anyway.

@deKay I wonder if iOS is trying to hijack the links for Safari, but then silently failing to load them? I'm using Lagrange for Gemini and Fedilab for Mastodon on my Android phone, and it Just Works: tap the link in Fedilab and it opens in Lagrange.
