“Watch Dogs” Inspired Hacking Drone Takes Flight

They say that life imitates art, which in modern parlance basically means if you see something cool in a video game, movie or TV show, you might be inclined to try and build your own version. Naturally, such things generally come in the form of simple props, perhaps with the occasional embedded LED or noise making circuit. It’s not as if you can really build a phaser from Star Trek or a phone booth that’s bigger on the inside.

But after seeing the hacking quadcopter featured in the video game Watch Dogs 2, [Glytch] was inspired to start work on a real-world version. It doesn’t look much like the drone from the game, but that was never the point. The idea was to see how practical a small flying penetration testing platform is with current technology, and judging by the final build, we’d say he got his answer.

All the flight electronics are off the shelf quadcopter gear. It’s running on a Betaflight OMNIBUS F4 Pro V2 Flight controller with an M8N GPS mounted in the front and controlling the 2006 2400KV motors with a DYS F20A ESC. Interestingly [Glytch] is experimenting with using LG HG2 lithium-ion cells to power the quad rather than the more traditional lithium-polymer pack, though he does mention there are some issues with the voltage curve between the two battery technologies.

But the real star of the show is the payload: a Hak5 Pineapple Nano. As the Pineapple provides a turn-key penetration testing platform on its own, [Glytch] just needed a way to safely carry it and keep it powered. The custom frame keeps it snug, and the 5 Volt Battery Eliminator Circuit (BEC) on the DYS F20A ESC combined with a female USB port allows powering the Pineapple without having to make any hardware modifications.

We’ve seen quadcopters with digital weaponry before, though not nearly as many as you might think. But as even the toy grade quadcopters become increasingly capable, we imagine the airborne hacking revolution isn’t far away.

Upgrading a 3D Printer with OctoPrint

If you’ve been hanging around 3D printing communities, or reading the various 3D printing posts that have popped up here on Hackaday, you’ve almost certainly heard of OctoPrint. Created and maintained by Gina Häußge, OctoPrint allows you to turn an old computer (or more commonly a small ARM board like the Raspberry Pi or BeagleBone) into a network-accessible control panel for your 3D printer. Thanks to a thriving collection of community developed plugins, it can even control other hardware such as lights, enclosure heaters, smart plugs, or anything else you can think to hook onto the GPIO pins of your chosen ARM board. The project has become so popular that the new Prusa i3 MK3 has a header on the control board specifically for connecting a Pi Zero W running OctoPrint.

Even still, I never personally “got” OctoPrint. I was happy enough with my single printer connected to my computer and controlled directly from my slicer over USB. The majority of the things I print are of my own design, so when setting up the printer it only seemed logical that I would have it connected to the machine I’d be doing my designing on. If I’m sitting at my computer, I just need to rotate my chair to the right and I’m at my printer. What do I need to control the thing over WiFi for?

But things got tricky when I wanted to set up a second printer to help with speeding up larger projects. I couldn’t control them both from the same machine, and while I could print from SD on the second printer if I really had to, the idea seemed painfully antiquated. It would be like when Scotty tried talking into the computer’s mouse in “Voyage Home”. Whether I “got it” or not, I was about to dive headfirst into the world of OctoPrint.
