    This DIY machine mixes your favorite three-ingredient cocktail

    Arduino TeamDecember 12th, 2017

    Do you and your friends have a favorite cocktail? If so—and if it has three ingredients—then this Arduino-based cocktail machine from YouTuber “GreatScott!” may be worth checking out.

    The device is capable of mixing three liquids, which in GreatScott’s case consist of vodka, cranberry juice, and grapefruit juice (also known as a Sea Breeze), in a drink size selected via a rotary encoder and LCD screen.

    An Arduino Nano provides the brains for this operation, and each component is poured using a series of three peristaltic pumps. Meanwhile, a load cell underneath the glass holder ensures that the correct amount of liquid is dispensed.

    The same setup could be used to make different three-ingredient drinks with a little programming work, or it could be expanded into a multi-drink unit with the addition of a few more pumps. You can see it in action below!

    Create a beat by nodding your head

    Arduino TeamDecember 11th, 2017

    If you are really enjoying a song, you may start to bob your head to the tunes, but what if you could instead create actual music with this subtle movement? That’s exactly what Andrew Lee’s “Nod Bang” system accomplishes.

    An accelerometer mounted to a pair of headphones senses nods in order to dictate the beat, while four 3D-printed arcade buttons are used to select which sounds will be played. An Arduino takes these inputs and passes them to a computer via a MIDI USB interface. The board also controls lights on the buttons for visual feedback.

    Be sure to check it out in action below and read Lee’s entire write-up here.

    The Imperializer makes quick work of metric conversions

    Arduino TeamDecember 6th, 2017

    When you work in a machine shop, you often need to convert numbers from metric to imperial. As long as you have to do this on a regular basis, why not make a tool to do so easily?

    Instead of pulling out a phone or taping a calculator to their CNC machinery, NYC CNC came up with an Arduino Nano-based device that does this conversion in style. “The Imperializer” features a beautifully milled enclosure that magnetically sticks onto a machine, a backlit LCD, and a toggle switch to flip between metric and imperial units.

    The Imperializer is a desktop or machine mountable device that does one thing: converts inches to millimeters (and millimeters to inches)!  It uses an Arduino Nano and is powered by a Lithium battery that can be recharged with a Micro-B USB cable!

    If you’d like to have your own for your shop, the bill of materials and Arduino code can be found on the project page. The housing, and even a fully-assembled version, can be purchased here.

    Build your own antenna rotator/satellite tracking device

    Arduino TeamDecember 5th, 2017

    After finding that purchasing a tracking device for his satellite dish would be quite expensive, YouTuber “Tysonpower” decided to simply build one himself. What he came up is an assembly made with 3D-printed parts and extruded aluminum that uses a pair of NEMA23 stepper motors for movement.

    While it doesn’t quite work with the dish itself due to its offset weight, the concept was successfully used to track weather satellites using a VHF Yagi antenna.

    Control is provided via an Arduino Nano, which interfaces with a computer over USB serial that provides satellite information. You can check it out in the video below, and find more details in the project’s write-up.

    A chronograph rig for high-speed glass photography

    Arduino TeamDecember 5th, 2017

    To capture images of bullets “interacting” with various objects, photographic hacker Tyler Gerritsen created an impressive chronograph rig, able to measure the speed of a bullet launched from a rifle at 1000 meters per second. While the concept of measuring time from one sensor to another isn’t new, implementation at this speed required some interesting tricks.

    To accomplish this feat, Gerritsen designed his own sensor array using photodiodes in a reverse-biased setup, and even calibrated the clock speed of the Arduino Uno for control in order to account for any variation. Finally, the time between triggering a flash and light actually appearing had to be compensated for in the code, a different value for each type of equipment.

    The project write-up is a great read for anyone interested in this type of photographic or measurement technique, and the resulting photos can be seen here.

    Antique grandfather clock retrofitted with Arduino control

    Arduino TeamNovember 20th, 2017

    When you see a mechanical clock, you know on some level that it took a vast amount of expertise and craftsmanship to get working, but you might also assume that this could all be swapped out very easily with modern electronics. While this might be the case with a clock that only tells time, as David Henshaw shows with his project, once you add in extra features like a moon phase, date indicator, and chimes, things get complicated quickly.

    Henshaw began by purchasing an 1847 vintage clock from England without the movement—the parts that actually it tell time. He then replaced the mechanical assembly normally found inside with stepper motors, sensors, an Arduino Uno, and a variety of other wires and bits.

    You can see the retrofitted grandfather clock in action below, while the build process (which took the better part of a year) and Arduino code he used are outlined on his website.

    Arduino TeamNovember 20th, 2017

    Sequencers, as YouTuber “LOOK MUM NO COMPUTER” explains, are musical devices that go through a sequence of tones one by one. While this can be done quite simply with a 4017 counter chip, if you instead substitute in an Arduino board for the counter, you can make your gadget behave normally, go backwards, or even act as a sort of keyboard using input buttons.

    This particular project employs a Nano for control, giving it a conveniently small form factor to fit inside your equipment.

    Since the start of building modular synths, ive always been looking for an arduino powered sequencer. but never really happy with the projects that were about. because it was still menu dives and button combinations. which is not what you wanna be messing about with! you may aswell use a computer and a mouse ha.

    Have you ever wanted a vending machine for snacks but didn’t know where to start? With an Arduino Mega, some motors, and an infrared sensor to detect coins, Dejan Nedelkovski decided to build his own using only hand tools.

    The DIY vending machine’s structure is made out of MDF, and uses wires bent into helical shapes to twist items out of four storage spaces with continuous rotation servos. While they could just drop to the bottom, Nedelkovski added a little extra flair and constructed an elevator system powered by stepper motors to gently lower the chosen treat to the exit opening.

    If you want to make your own custom PCBs at home, one method is to paint a circuit board blank with photosensitive material, then expose the portion you don’t want to UV light using a printed transparency. After a process of etching and stripping, the correct traces are generated.

    As seen here, in order to help with the UV process, GiorgiQ decided to create his own two-sided exposure box. It uses arrays of LEDs to produce the correct light, and an Arduino Nano for control.

    The box itself is constructed out of MDF, white acrylic, and drawer slides to allow for easy insertion and extraction of the PCBs. It looks like an excellent tool, and his instructions would be a great place to start if you want to build your own!

    Creating a classroom quiz machine with Arduino

    Arduino TeamNovember 14th, 2017

    Quiz games, where contestants try to “buzz” in and answer questions make for fun televised game shows, but they can also be great for making learning fun. In order to avoid paying several hundred dollars for an official quiz machine, Instructables user “arpruss” decided to build one for his school using an Arduino Mega.

    The device uses a series of CAT-6 cables to connect individual arcade-style buttons to a central control unit with RJ45 connectors, allowing each contestant to buzz in with an answer. While not approved for official competition, the system can pick out button presses down to a precision of 50 microseconds or less and displaying the order on an LCD screen, reliably determining the fastest individual nearly all of the time!

    The Certamen quiz team competition from the Junior Classical League involves quiz questions on Greek/Roman subjects. Individual contestants press buzzer buttons when they have an answer. The machine keeps track of the order in which buttons were pressed, subject to the team-lockout rule that once a player on a team presses a button, the other presses from that team don’t count. The machine we built was for three teams of four players each. Additionally, so that other school groups could use the machine as a standard quiz machine, there is an option to disregard teams and just keep track of button order.

    Alejandro Clavijo, together with his father Jerónimo, spent two years building the first official fan-made model of the R4-P17 Star Wars droid. For those not familiar with this family of droids, R4-P17 was the robot companion to the young Obi-Wan Kenobi.

    The replica is made of aluminum and wood, and runs on four Arduino boards. Impressively, the project has also been approved by Lucasfilm, the studio behind the saga, allowing Clavijo to bring it to official Star Wars events all over the world.

    Clavijo sent us a bunch photos showing R4-P17’s construction, and more can be found over on its website. As you can imagine, the robot has been a big hit, already making several appearances on TV and in a number of blogs.

    When not recreating Star Wars characters, Clavijo spends his days working as an engineer and has designed controls for “clean rooms” using Arduino Uno. You can see his design–made with CATIA–on Thingiverse.

    Strandbeests, as originally conceived, are gigantic PVC creatures that walk across the sand under wind power. While building one is certainly an enormous undertaking, smaller models are available that let you experience this strange kinetic motion in a more approachable size. These are also normally propelled by moving air, but maker “ArduinoDeXXX” decided to take things further with a pair of DC motors and an Arduino Nano.

    The project came together over five distinct iterations, starting off with the normal wind-driven version, then adding uncontrolled motors. After that, the Arduino was included for automation, and this was upgraded with an IR remote. Finally, ArduinoDeXXX integrated simple gesture sensing using an array of IR LEDs.

    You can see the mini Strandbeest in action below, along with a few “bonus” improvements at the end.

    Simple Computer Gesture Control with Arduino and Python

    Arduino TeamNovember 6th, 2017

    As outlined in this Circuit Digest write-up, with the right hardware, you can now control your computer using hand gestures. While interesting, this kind of technology can be a little expensive. But if you’d like to augment your notebook or laptop via simple gesture capabilities without breaking the bank, B. Aswinth Raj has your answer in the form of an Arduino Uno and two ultrasonic sensors.

    His system places the two sensors at the top of a screen, which are read by the Uno. This data is then passed on to a Python program running on the host computer that allows for actions such as play/pause, fast-forward, and volume control while watching videos.

    Given the nature of the setup, there’s no reason why more sensors or programming couldn’t be added for further control, perhaps as shortcut “keys” for your favorite design software package! You can read more about the project here, and see a demo of it below.

    IT professional (and Arduino cap fan) John Milner had a minor problem. While his retro gaming setup could emulate a wide variety of systems and games, it was still missing the tactile feedback of the original controllers. Rather than “submit” to playing with only an Xbox 360 controller, he developed the Multijoy Retro Gaming System that can change gamepads with the turn of a knob using an Arduino Micro.

    The resulting system lets him not only choose the original controller for each game, but if you want to mix things up and see how Super Mario Bros. would feel on a PlayStation 1, or even a Genesis controller, you can do that too! It also features shortcut buttons on the new console.

    The Arduino presents itself as two joypads with native plug-and-play support for Microsoft Windows 7+ and Linux/RetroPie. The selector is simply a ring of LEDs with a potentiometer in the center, using the knob will move the lit LED to the desired controller pictured in that position, a simple system with an unexpected bonus of being a little retro in its appearance.

    Linux support comes to Arduino Create

    Arduino TeamNovember 3rd, 2017

    We’re excited to announce a new update to the Arduino Create web platform, which will enable fast and easy development and deployment of IoT applications with integrated cloud services on Linux-based devices.

    What this means is that users will be able to program their Linux boards as if they were regular Arduinos. Multiple Arduino programs can run simultaneously on a Linux board and programs can communicate with each other leveraging the capabilities of the new open source Arduino Connector. 

    Arduino Create Cloud now allows users to manage individual IoT devices, and configure them remotely and independently from where they are located. To further simplify the user journey, we’ve also developed a novel “out of the box” experience that will let anyone set up a new device from scratch via the cloud without any previous knowledge by following an intuitive web-based wizard

    The initial release has been sponsored by Intel® and supports X86/X86_64 boards. As a reference implementation, a simplified user experience has been designed for the AAEON® UP² board, although other platforms are already supported by the Arduino Create Cloud platform, such as the Intel® NUC, Dell Wyse®, Gigabyte™ GB-BXT.

    In the coming months, we plan to expand support for Linuxbased IoT devices running on other hardware architectures. Until then, you can find more information here and follow the tutorials below to help get you going:

    The documentation found here is excellent; however, it comes with a warning that this is a very advanced project, taking several months to build along with $2,500 in parts. Even if you’re not willing to make that commitment, it’s worth checking out for inspiration, perhaps parts of the ASPIR could be adapted to your own design!

    Manipulate time with this Arduino-controlled LED glove

    Arduino TeamNovember 2nd, 2017

    While you might not be able to actually manipulate time, this glove by YouTuber “MadGyver” certainly makes it appear that way. His glove, shown in the video below, uses a gigantic LED controlled by an Arduino Nano to allow objects such as a fan, water falling from a shower, and a spinning top to stop, slow down, and even reverse.

    The trick is that when the LED’s frequency is aligned with that of the observed moving subject, it lights it up in the same position over and over, making it appear to pause. Frequency is adjusted by rolling one’s hand via an accelerometer, or a potentiometer mounted in the base of the glove can also be used.

    If you want to build your own, instructions can be found here and the Arduino code and schematics are available on GitHub.
