Most Beautiful Mini-Galaga-Pi Ever!

The problem with click-bait titles, besides the fact that they make the reader feel cheated and maybe a little bit dirty for reading the article, is that they leave us with nothing to say when something is truly outstanding. But the video of [Tiburcio de la Carcova] building up a mini-Galaga cabinet (complete with actual tiny CRT screen from an old portable 5″ TV) is actually the best we’ve ever seen.

Plywood is laser-cut. Custom 3D printed parts are manufactured and assembled, including the joysticks and coin door. Aluminum panels are cut on a bandsaw and bent with a hand brake. Parts are super-glued. In short, it’s a complete, sped-up video of the cutting-edge of modern DIY fab. If that’s not enough reason to spend four minutes of your time, we don’t know what is.

[Tiburcio] has also made a mini Space Invaders, and is thinking of completing the top-20 of his youth. Pacman, Asteroids, and Missile Command are next. We can’t wait.

There are (ahem) a couple of Raspberry-Pi-powered video game emulators on Hackaday, so it’s a little awkward to pick one or two to link in. We’ll leave you with this build that also uses a small CRT monitor to good effect albeit in less-fancy clothing.

Robot vacuum makes cleaning into a game

This is not a Roomba hack, but a ground-up vacuum cleaner robot build. It’s the result of a class project from six students at the Royal Institute of Technology in Sweden. There’s a slew of information available in their paper, but fair warning that it’s an 8.6 MB PDF file that we couldn’t get Google to translate. We were able to skim the PDF and cut and paste to translate the interesting bits we found.

Unlike a Roomba, which just uses a little sweeper to pick up debris, this robot actually includes a vacuum. The image above shows that the cylindrical body is wrapped in an LED matrix, with an ultrasonic sensor on the frontĀ for obstacle avoidance. The robot uses a CAN bus to control the various modules inside. We don’t think there’s any autonomous function, but that’s made up for by the remote control. It communicates via a ZigBee module, and includes a d-pad, touch screen, and accelerometer.We’re a little bit hazy on how the games are played, but there are at least two interactive version: one called ball, and another modeled after the classic game of missile command.

You can check out the source code for the project in their repository, or join us after the break for two demo videos.
