    Arduino Nerf Tank

    Makers love Nerf guns, but Nathan Li takes foam-based home security to a new level with his mini Nerf tank. Naturally there’s an Arduino Uno in there, powering the mobile dart launcher.

    Scruffy lookin’ Nerf tank herder

    This miniature roving robot, known as M.A.T. (Modular Arduino Tank), is beautifully built. Not only is it remarkably accurate, but the dart launching mechanism is a triumph of non-lethal weapon design.

    Unlike the majority of Nerf mods out there, this tank doesn’t actually use any parts from a toy gun. Attached to the front of the dart turret is a pair of flywheel motors. These spin the flywheels in opposite directions, at a pretty fast rate. An arm mounted on a servo feeds a dart into the flywheels, which propel it at an impressive lick!

    The next dart is gravity fed, and simply falls into place, making it quite a rapid firing micro tank.

    Testing the tank

    Li takes his tank through a series of batteries, all of which show impressive results. Accuracy is spot on, which isn’t easy with notoriously unreliable Nerf darts. A five-foot muzzle velocity test achieves a whopping 35MPH dart speed. The distance test sends foam projectiles an impressive 44 feet.

    Then there’s a demonstration of some excellent grouping in the accuracy test.

    It’s sparked up a whole conversation over on Reddit about how the firing mechanism can be modified. The flywheel thrower operates much like baseball launchers (and this dog toy, for example), which has really captured the maker community’s imagination. Shooting dried peas seems to be a popular idea. As does the idea of building in object detection for pest control.

    The maker has shared his Arduino code on GitHub. You can also find the 3D print files and a build guide on Li’s website.

  • Reef-Pi: the ultimate Raspberry Pi fish tank management system

    Reef-Pi: the ultimate Raspberry Pi fish tank management system

    Reading Time: 3 minutes

    If you’ve ever had a pet fish, even the saddest of fairground goldfish, you’ll appreciate how much work and attention they require. And to those who have never owned a fish: believe me, it’s more than you’d assume.

    Reef-Pi

    And the moment you upgrade from goldfish to brightly coloured, tropical beauties, and replace the standard silk reeds and gravel with live aquatic plants and soil, you suddenly have to factor in things like optimum temperature and chemical levels.

    Reef-Pi

    Reef-Pi

    Thankfully, Adafruit Learning System author and loving fish parent Ranjib Dey has been working on a tutorial series called Reef-Pi, a collection of how-to guides that help you build the ultimate in Raspberry Pi reef aquarium management system.

    Reef-Pi monitors pH, chemical, and water levels, controls temperature, light, and power, and automates the management of these aspects so you don’t have to think about them. Phew!

    And if you don’t fancy a massive coral-filled saltwater tank like Ranjib’s, you can use parts the Reef-Pi series for your own tank, whatever its setup, because many of the operations are similar or easy to adjust for your needs.

    Jean Tannen

    Any excuse to show off beautiful Jean to the world

    Take, for example, my new Betta, Jean Tannen. While Jean’s tank is a much smaller size, and Jean its only resident (for now), I still need to keep an eye on the chemical balance of his water, the heat of his tank, and when his lights should be turned on or off. Even the most commonplace goldfish will appreciate many of the services Reef-Pi automates.

    The Reef-Pi system uses a variety of components, including Raspberry Pi Zero and/or Raspberry Pi 3, and each stage of building the project is well-documented on the Adafruit Learning System. So if you’re looking to upgrade your tank, or have always fancied having pet fish but don’t want the hassle of tank management, give Reef-Pi a gander and see what you think.

    We’re going to try it!

    Sarah, our new Operations Manager, has been looking to upgrade her giant fish tank with a Raspberry Pi or two, so we’ll be sure to share her progress in the new year. If you decide to give Reef-Pi a try, or have already automated your tank with a Pi, let us know in the comments, or tag us on Twitter or Instagram!

  • Quadcopter-Tank – B-Unstoppable full performance Test

    Quadcopter-Tank – B-Unstoppable full performance Test

    Reading Time: < 1 minute

     

    What happens when you combine a remote-controlled tank and quadcopter drone into one? The B-Unstoppable of course. Not only can it handle just about any terrain, once the going gets really tough, just fly it over the impassable stuff. It can even turn 360° on the spot, and is equipped with an HD (1280 x 720) camera to capture all the action. Tread tension is maintained by arms that flex in and out by up to 4mm at either end as it goes over obstacles. The propellers sit flush with the treads when in „ground mode“.

  • Russia reveals its latest tank is controlled by a PLAYSTATION controller!

    Russia reveals its latest tank is controlled by a PLAYSTATION controller!

    On May 9th, the Kurganets-25 made its public debut as part of a parade commemorating the 70th anniversary of Russia’s victory in World War II.

    The new Russian armoured vehicle platform uses a device similar to a Playstation controller, the manufacturer’s vice-president told Russian media.

    The new Kurganets-25 infantry fighting vehicle uses a ‚console similar to a Sony Playstation gamepad,‘ Tractor Plants vice-president Albert Bakov told state owned outlet Sputnik.

    ‚I spent two years on convincing the designers to make the console similar to a Sony Playstation gamepad, to make it easier for a young soldier to familiarize himself with it,‘ Bakov said.

    According to Bakov, the idea of left-right coordination, as well as the fact that the gamepad form has been perfected for decades made it a good choice.
