Your tablet could double as a second monitor. Here's how Samsung Second Screen and Apple Sidecar work, and when a dedicated display is worth buying.

LOS ANGELES—For about five minutes on an extremely crowded showroom floor, I got to take pictures of the new MacBook Pro and test out some of its new features. First impressions: It's not as much of a departure from the previous design as I expected, but the outstanding OLED display steals the show regardless.
The first thing I noticed was that it's lighter. My daily driver is a 14-inch MacBook Pro (M1 Max), and it's a bit weighty for a 14-incher. Picking up the new model, I could immediately tell it was lighter. It's not like it's in a different general weight class, but it's a noticeable difference.

Text messaging has been around on cellular networks en masse for around three decades now. It’s so common that it’s difficult to remember a time without it. Its two-way quick messaging is incredibly useful, but for even simpler communications there’s a one-way system that predates it. Pagers are able to receive simple messages, but outside of hospitals are rarely used nowadays. Eventually some added in two-way communications like this Motorola T900, but they’re still mostly obsolete. That’s why [zindustries87] converted it to operate on the Meshtastic network instead.
To get this pager working, a lot of reverse engineering was needed. There is essentially no documentation on the chips in these devices, so the screen and keyboard both were reverse-engineered to work with other hardware. In this case, [zindustries87] found space for a Heltec V4 with an ESP32-S3, a popular Meshtastic node with a small form factor. Some programming was needed to get everything communicating together, but from the looks of things it seems to have basic functionality.
[zindustries87] points out that this is a prototype, and didn’t know going in if the keyboard and screen could be brought back to life, or if the other hardware would fit in the case. But with it working on this level, they plan to add a number of other features in and possibly build a drop-in PCB replacement for these devices. They were once fairly popular so there are plenty around, and they’re a good form factor for a dedicated Meshtastic device that doesn’t need a smartphone to work. The only other ways of bringing pagers back to life involve bootstrapping an entire pager network, and Meshtastic is a bit more useful than that now.
