Here’s what a rifle running Linux can help you do:
The spotter and I monitor Steve’s sight through an iPad linked to the rifle via Wi-Fi, and we can see exactly what he’s seeing through the scope. Steve lines up on his target downrange—a gently swinging metal plate with a fluorescent orange circle painted at its center—and depresses a button to illuminate it with the rifle’s laser.
“Good tag?” he asks, softly.
“Good tag,” replies the spotter, watching on the iPad. He leaves the device in my hands and looks through a conventional high-powered spotting scope at the target Steve has selected. The wind stops momentarily. “Send it,” he calls out.
Steve pulls the trigger, but nothing immediately happens. On the iPad’s screen, his reticle shifts from blue to red and drifts toward the marked target. Even though I’m expecting it, the rifle’s report is startling when it fires.
A second later, the spotter calls out, “That’s a hit!”
Steve has just delivered a .338 Lapua Magnum round directly onto a target about the size of a big dinner plate at a range of 1,008 yards—that’s ten football fields, or a tick over 0.91 kilometers. It’s his very first try. He has never fired a rifle before today. [Emphasis added, because -- DAYUM!]
There’s video at the link. You’ve got to see this thing in action.
