Watching robots doing sports is pretty impressive from a technical viewpoint, although we secretly smile when we compare these robots’ humble attempts to our own motoric skills. Now, a new robot named Robomintoner seeks to challenge human players, and it’s already darn good at badminton.

Most of our beloved tools, such as Slic3r, Cura or KISSlicer, offer scripting interfaces that help a great deal if your existing 3D printing toolchain has yet to learn how to produce decent results with a five headed thermoplastic spitting hydra. Using scripts, it’s possible to tweak the little bits it takes to get great results, inserting wipe or prime towers and purge moves on the fly, and if your setup requires it, also control additional servos and solenoids for the flamethrowers.
This article gives you a short introduction in how to post-process G-code using Perl and Slic3r. Perl Ninja skills are not required. Slic3r plays well with pretty much any scripting language that produces executables, so if you’re reluctant to use Perl, you’ll probably be able to replicate most of the steps in your favorite language.

If you are running out of swear words to comment the magic smoke coming from your electronics, [Howard] has just the right weekend project for you: The reverse swear box. Most swear boxes would have you drop in a coin as penance for uttering your choice phrases. Instead, at the touch of a button, this obscure but classy device randomly suggests a four letter swear word and displays it on a 14-segment LED display for immediate or later use.
It’s built upon an ATmega168 and only requires a minimum of external components. The schematics and firmware for this project are freely available on the project page. There’s also an extremely profane header file, packed with 37 case-insensitive four-letter words you may not actually want to include in your toolkit. On the other hand, many of these words score intimidatingly well at Scrabble.
Using Xcode to spoof GPS locations in Pokemon Go (like we saw this morning) isn’t that much of a hack, and frankly, it’s not even a legit GPS spoof. After all, it’s not like we’re using an SDR to spoof the physical GPS signal to cheat Pokemon Go.
To [Stefan Kiese], this isn’t much more than an exercise. He’s not even playing Pokemon Go. To squeeze a usable GPS signal out of his HackRF One, a $300 Software Defined Radio, [Stefan] uses an external precision clock. This makes up for the insufficient calibration of the HackRF’s internal clock, although he points out that this might also be fixed entirely in software.

Pokemon Go inherits a certain vulnerability to GPS location spoofing from it’s predecessor Ingress, but also the progress that has been made in spoof detection. Since taking advantage of a game’s underlying mechanisms is part of the winner’s game, why not hook up your smartphone to Xcode and see if you can beat Niantic this time? [Dave Conroy] shows you how to play back waypoints and activate your Pokemon Go warp drive.

Pokemon Go has done a great service to the world health. Or would’ve done, if we wouldn’t hack it all the time. The game suggests, you breed Pokemon eggs by walking them around, but [DannyMcMurray] has a better idea: Strapping your smartphone to the propeller of a fan and taking them for spin that way.

3D Printering: the final frontier. These are the voyages of another 3D printer hack. Its mission: to explore strange new ways of leveling a print bed.
So far, we’ve had servo probes, Allen key probes, Z-sled probes, inductive and capacitive contactless switches, just to name a few. All of them allow a 3D printer to probe its print bed, calculate a correction plane or mesh, and compensate for its own inherent, time variant, inaccuracies.
