"XDA Phone" F(x)tec Pro1X... Is a Massive Disappointment
The Pro1X is an unmitigated disaster that starkly highlights the risks of backing electronics projects on crowdfunding sites. If you’re looking for a mobile phone with a physical keyboard built-in, look instead for something more accomplished, like the Planet Computers Cosmo Communicator or even a second-hand Blackberry.

I wanted to be able to demonstrate the Ubuntu Touch or PostmarketOS experience on the F(x)tec Pro1X. Indeed, a key reason for backing the project was to have a working, flexible Linux phone. Unfortunately, there is no version of either (or any other Linux-based phone OS) that will run on the F(x)tec Pro1X without missing the most basic of features (e.g. telephony, networking, camera).
Given how long the phone has been in development, and the availability of the Pro1 and early releases of the Pro1X, this seems like an unforgivable oversight.

ELLO LC1 - A 2mm thin DIY "computer" based on Microchip PIC18 8-bit MCU - CNX Software
We often write about business card or credit card-sized boards, but it’s only true for 2D dimensions, as most boards are over a centimeter thick, with possibly the thinnest we’ve covered being the Khadas Edge2 SBC that’s just 7mm thick.

Digitize your collection of 35mm slides | Arduino Blog
Sharing photos used to be a difficult task. Even after paying for someone to develop your photos and waiting to get them back, you’d end up with small prints that your friends would have to huddle around. One common alternative was 35mm slide projection. Photographers could snap images and then have them developed as 35mm slides. They could then pop those into a slide projector that would blow up the image on a screen or wall where everyone could see the photo. If your family has a large collection of 35mm slides, this Instructables tutorial will help you digitize them.
As great as 35mm slides were, they don’t have much of a place in our modern world. Not many people have working slide projectors these days and most would prefer digital photos that they can share on social media, store on their computer, or display on a TV. There are 35mm slide digitizing services, but those can cost more than 50 cents (USD) per slide. That becomes very expensive if your slide collection is large. If you have a slide projector, even if its projection bulb is burnt out, this tutorial will help you digitize the slides by snapping photos with a modern DSLR camera.

Add ML-controlled smart suspension adjustment to your bicycle | Arduino Blog
Some modern cars, trucks, and SUVs have smart active suspension systems that can adjust to different terrain conditions. They adjust in real-time to maintain safety or performance. But they tend to only come on high-end vehicles because they’re expensive, complicated, and add weight. That’s why it is so impressive that Jallson Suryo was able to add a similar smart suspension adjustment system to his bicycle.
This system will only work on specific bicycles that have suspension forks that the user can adjust with a knob. A servo-driven mechanism mounts onto the fork and turns the knob to tweak the firmness and rebound of the front suspension. Normally the rider would need to stop and turn that knob by hand when necessary, but this system can perform that adjustment automatically in response to the current conditions. It can recognize and accommodate five different conditions: idle, medium, rough, smooth, and sprint.
