LoRa now supports mesh networking thanks to Meshtastic, an open-source platform enabling secure, low-power, long-range ...

While the idea is not that new, there is always a different way to accomplish a goal. An Arduino is used to control a pair of stepper motors which were sourced for pretty cheap, and even came with ...

A speaker is a transducer and like many transducers, it will work — to some extent — in either direction. A servo motor manages the deadbolt. An Arduino runs the whole thing.

The case's design remains similar to the Watch 4, with its serrated digital crown and push-button setup. The X-Tap module is a new addition, positioned between the two. This pressure-sensitive ...

You don’t even see the air-con vents, which are hidden behind a panel. The turn signal is a stalk (unlike the confusing button setup on the Model 3), and storage is thoughtfully designed, with covered ...

Furthermore, the physical button setup interferes with the buds’ comfort levels. Enacting multi-press commands had my right ear in pain for most of the day. For all the unique functionality ...
