    GymSoles ensure correct form and posture during your workout

    Arduino Team — May 16th, 2019

    While you can get a very good workout on your own, it’s ideal if you have someone else watching over your form. This, of course, isn’t always practical, so researchers at the University of Auckland’s Augmented Human Lab have prototyped a wearable system called GymSoles to help. 

    GymSoles consists of a pressure-sensitive insole that is used to determine a foot’s center of pressure, and thus infer whether or not the participant is keeping the weights in the proper position relative to his or her body—perfect for exercises like squats and deadlifts. 

    Feedback is provided visually as well as through tactile feedback via eight vibrating motors, allowing participants to modify technique without having to focus on a screen. A computer is used to control the device using an Arduino Uno with motor drivers and an I2C multiplexer.

    The correct execution of exercises, such as squats and dead-lifts, is essential to prevent various bodily injuries. Existing solutions either rely on expensive motion tracking or multiple Inertial Measurement Units (IMU) systems require an extensive set-up and individual calibration. This paper introduces a proof of concept, GymSoles, an insole prototype that provides feedback on the Centre of Pressure (CoP) at the feet to assist users with maintaining the correct body posture, while performing squats and dead-lifts. GymSoles was evaluated with 13 users in three conditions: 1) no feedback, 2) vibrotactile feedback, and 3) visual feedback. It has shown that solely providing feedback on the current CoP, results in a significantly improved body posture.

    VR boxing robot actually punches back

    Arduino Team — May 15th, 2019

    VR environments are meant to be immersive, but if you’ve ever thought what was missing is being actually pummeled by robotic fists, then James Bruton’s newest project could be just the thing. 

    Bruton recently teamed up with students from Portsmouth University to build a robot that works in the real world, and coordinates its movements with a virtual setting displayed on the human’s headset.

    The robot itself is controlled by an Arduino Mega, and features a differential (tank) drive with encoders for feedback. Shoulders can tilt from left to right, and the actual punching motion is handled by pneumatic actuators built from modified bicycle pumps. Robo-fists are covered by boxing gloves to keep humans relatively safe, and flesh-based competitors are given a small shield and sword-bat with which to fight back!

    I worked on this project with final year degree students in Computer Games Technology at Portsmouth University CCI faculty. The robot hardware is controlled over a serial interface, the team built an VR game which controls the robot, so when you get hit in VR you get hit in real life! The robot is tracked back into VR with Vive trackers so it stays in sync.

  • Program smart devices with a ‘magic wand’

    Program smart devices with a ‘magic wand’

    Arduino Team — May 15th, 2019

    Consider how interactive devices have come to dominate our lives. Once the purview of a select few in large laboratories, powerful gadgets—supercomputers even—are carried with us everywhere we go in the form of smartphones. And as everything around us becomes increasingly more connected, those that have no interest in the technical aspects of computing will still need to know how to configure the networked things throughout their homes.

    As an experiment in interactive design, Austrian researchers Florian Güldenpfennig, Daniel Dudo, and Peter Purgathofer have come up with a ‘Magic Paradigm’ for programming.

    Their project uses a wand with a built-in RFID reader, allowing it to sense which RFID tagged object it’s pointing to and register various sequences. This enables devices to be customized as needed, many of which contain an Arduino Nano as ‘active’ units and an nRF24L01+ module for communication. A central desktop/Arduino setup is also implemented to coordinate system elements.

    We are surrounded by an increasing number of smart and networked devices. Today much of this technology is enjoyed by gadget enthusiasts and early adaptors, but in the foreseeable future many people will become dependent on smart devices and Internet of Things (IoT) applications, desired or not. To support people with various levels of computer skills in mastering smart appliances as found, e.g., in smart homes, we propose the ‘magic paradigm’ for programming networked devices. Our work can be regarded as a playful ‘experiment’ towards democratizing IoT technology. It explores how we can program interactive behavior by simple pointing gestures using a tangible ‘magic wand’. While the ‘magic paradigm’ removes barriers in programming by waiving conventional coding, it simultaneously raises questions about complexity: what kind of tasks can be addressed by this kind of ‘tangible programming’, and can people handle it as tasks become complex? We report the design rationale of a prototypical instantiation of the ‘magic paradigm’ including preliminary findings of a first user trial.

  • This compass reads the correct heading even when tilted

    This compass reads the correct heading even when tilted

    Arduino Team — May 15th, 2019

    Consider an analog or even digital compass. While you can reasonably expect either to point towards magnetic north when held flat, when you add tilt and/or roll to the equation, things get a bit wonky. That is unless you’re maker “lingib,” who was able to construct a magical compass using an Arduino Uno and an MPU-9250 IMU unit, with an accelerometer/gyro in the same package.

    As seen in the video below, when the compass unit is set at an angle, the heading output varies significantly—as much as 100 degrees according to the project write-up. When stabilization is turned on, however, the gyro/accelerometer is used to compensate for magnetometer heading variations—reducing output errors to just a few degrees.

    This Instructable explains how to make a tilt compensated compass using an Arduino Uno R3, an LCD display, and an IvenSense MPU-9250 multi-chip-module that contains an MPU-6050 accelerometer / gyro and an AK8963 magnetometer within the same package.

    The LCD simultaneously displays the heading, (P)itch, and (R)oll.

    The heading accuracy is within 2 degrees depending on how well the compass has been calibrated.

    Without tilt compensation the compass headings vary significantly … sometimes by as much as 100 degrees.

    When stabilised, the tilted compass headings only vary by one or two degrees … the improvement is amazing.

    The tilt stabilization may be disabled by placing a jumper wire between Arduino pins A0 and GND.

    Modular CNC machine made with Arduino

    Arduino Team — May 15th, 2019

    Arduino boards running GRBL software have long been used for CNC machine control, but usually you need to choose between having a router or laser cutter. This project, however, is specifically designed to accommodate both with a modular carriage system.

    Build-wise, it’s a fairly standard XYZ gantry CNC — with a frame made out of V-slot aluminum extrusions from OpenBuilds cut to length by a circular saw. The X and Y axes are controlled via NEMA 17 stepper motor and belt drive assemblies, while height adjustment is accomplished with a NEMA 23 motor and screw drive.

    The electronics are all hidden away in a separate enclosure, including the Arduino Uno/CNC shield that serves as the brains of the operation and a cooling fan to keep the temperature inside in check. 

    If you’ve been considering doing this type of build, this looks like a great place to start, and you can see a demos of it in laser and spindle modes in the videos below.

    Current limiting Hacky Racer throttle

    Arduino Team — May 15th, 2019

    Hacky Racers, an electric vehicle racing series that’s part of the Power Racing Series, encourages drivers to put together their own hacky vehicle. While it looks like a lot of fun, in order to keep things relatively safe, current powering the car is regulated by an inline fuse from the battery, effectively limiting the top power output to the motor—thus keeping speed in check.

    This means that while drivers need some control over how fast their motor is running, traditional PWM control where as much power is thrown to the motor as needed to keep it at a certain speed doesn’t really work. Instead, you need a system that controls how much current is provided. It’s a subtle problem, solved here with the addition of an Arduino Nano, which regulates output based on feedback from a current clamp sensor. While it won’t let a racer exceed the current limit, it does allow for maximum output when needed without tripping the fuse!

    Those wishing to learn more can read the full write-up here and check out Hackaday’s recent article.

    Washing machine becomes ‘universal’ rotary tool

    Arduino Team — May 14th, 2019

    If you have a broken washing machine, you may want to think twice before disposing of it. As Stephen John Saville shows in this multi-use rotary table project, they can provide a wealth of parts, from the actual physical structure/table of the build, to a motor that’s able to run via AC or DC, and various other mechanical components. There’s even an electronic timer salvaged from an old microwave.

    To keep the turntable running at the desired speed, he used an Arduino Nano connected to a triad circuit, along with an LM393 chip and optocoupler to implement closed-loop control. User feedback is shown on a 16×2 LCD screen, updated every two seconds to avoid interfering with speed control functions. 

    More info on this clever hack can be found in its well-detailed write-up, and be sure to check out the very entertaining video of what’s involved in such a repurposing feat below!

    Clean your whiteboard automatically with Wipy

    Arduino Team — May 8th, 2019

    If you have to do a lot of drawing on a whiteboard, you also have to clean it. Why not have a robot do this instead? That’s the idea behind Wipy, an Arduino Uno-based robot that uses magnets to stick to the board, along with grippy wheels and motors to power across your scribbles.

    Wipy employs an array of IR sensors that enable it to act as a line follower, plus a time-of-flight (ToF) sensor to detect your hand on the board. While one might assume this sensing arrangement would prevent it from erasing your work-in-progress, it annoyingly allows it to start erasing immediately when you start drawing. At least it has a cute LED face!

    Did you ever get tired of cleaning the whiteboard? Have you ever wondered how much your life would improve if a robot could do this for you? You now have the chance to make this a reality with Wipy: the overly motivated whiteboard cleaner. Wipy will properly clean your embarrassingly bad drawings, and it will even do it with a cute smile. You don’t even need to activate it! It will just clean the board when you least expect it… Uhhh…*cough cough*…we, of course, mean: when you need it most!

    – Our future friend will be able to stick to the board using magnets and is able to move through space using grippy wheels.

    – It will be able to follow a line and erase it using a line-following sensor and a sponge.

    – Wipy has the ability to measure the distance to your hand using a time-of-flight sensor.

    – We will give Wipy a cute personality using a small OLED screen.

    Do you like plants, but not so much tending to and watering them? If that sounds like you, then you might be interested in your own CNC growing machine. The system—created by 15-year-old maker “daily3dprinting”—is controlled by an Arduino Uno, and uses a single stepper motor to pull a watering head into position based on hygrometer readings.

    A relay is used to turn the grow light on at 6am and off at 8pm, and another to activate the unit’s water pump. A third relay is employed to power off the L298N stepper driver when not needed. 

    The project took home second place in the math and engineering category at daily3dprinting’s high school science fair, and more info on the build is available in its write-up here.

    If you want to show everyone your computer prowess—or perhaps get a little practice—binary clocks are a great way to do so. These clocks express time in 1s and 0s instead of 0 through 9, and while the concept is pretty simple, actually creating one is less than straightforward… or used to be.

    The Binary Clock Shield, now on Crowd Supply, aims to make this type of clock build extremely easy. This board plugs into an Arduino Uno and features 17 RGB LEDs to act as binary digits, along with an RTC module and backup battery socket.

    There are a wide variety of ways to create electronic music. For a capable machine that fits in the palm of your hand and is loud enough to use outdoors, however, it’s hard to imagine a battery-powered device cooler than Bitty from Curious Sound Objects. 

    The pocket-sized drum machine and synthesizer, currently on Kickstarter, was prototyped using an Arduino Nano and will be fully Arduino-compatible when released. This means that in addition to changing the sound and interface around with readily-available sound packs—which include Theremin Bitty, Techno Bitty, Basement Bitty, Trap Bitty, Lofi Bitty, and Beach Bitty—it can be programmed with the Arduino IDE. The device can even run sound software written for other Arduino boards.

    Bitty features four sample trigger buttons, a pair of knobs, and a speaker. Designed for entry-level EDM enthusiasts and studio musicians alike, you can play the drums and melodies manually, as well as trigger patterns to produce dance music or hip hop beats. These can be chosen via the left knob, while the right knob handles pitch, note selection, and arpeggiation.

    Use an LED matrix as a scanner

    Arduino Team — May 1st, 2019

    Consider that a digital camera uses an array of sensors to capture light from an object. Maker Marcio T, however, decided to turn this idea on its head and instead utilize an array of lights that are detected by a single sensor.

    The way it works is that as each LED in a 32×32 matrix illuminates, a phototransistor picks up light if the path is clear or sees no change if the path is blocked. So when you put an object on the matrix, the sensor is able to get an accurate picture of it, enabling its Arduino Uno controller to then generate its silhouette. 

    It’s a simple yet very clever hack, and if you pay close attention in the video below, you can see the lights scanning from the bottom to top before the image is produced.

    Ordinary digital cameras work by using a large array of light sensors to capture light as it is reflected from an object. In this experiment, I wanted to see whether I could build a backwards camera: instead of having an array of light sensors, I have just a single sensor; but I control each of 1,024 individual light sources in a 32 x 32 LED matrix.

    The way it works is that the Arduino illuminates one LED at a time, while using the analog input to monitor changes in the light sensor. This allows the Arduino to test whether the sensor can “see” a particular LED. This process is repeated for each of the 1,024 individual LEDs rapidly to generate a map of visible pixels.

    If an object is placed between the LED matrix and the sensor, the Arduino is able to capture the silhouette of that object, which is lit up as a “shadow” once the capture is complete.

    Arduino Team — May 1st, 2019

    Arduino boards have been employed in all sorts of robotics and IoT applications, although working with air as a power source is less than straightforward. In order to make this experience easier, the Programmable-Air pneumatics kit puts everything you need for simple air power experimentation into one package.

    It features pressure and vacuum pumps, as well as pneumatic valves and a pressure sensor. An Arduino Nano is implemented as the controller, and a custom library is available here, so programming should be a snap. 

    Programmable-Air has a built-in high-pressure pump, vacuum pump, pneumatic valves, pressure sensor, and an Arduino Nano. The output from Programmable-Air is a single tube that goes into your soft robot or pneumatic actuator. By controlling the motors and valves, you can push air in or out of the actuator, or let it exchange air with the atmosphere. All the while you get feedback about the state of the actuator through the pressure sensor.

    The kit is coming soon to Crowd Supply, so be sure to sign up there to be notified when it goes live!

    Off-the-shelf remote-controlled cars can be a lot of fun, but Clem decided to take things up several levels with his heavily modified rig. 

    In the hack shown below, he outfitted an RC vehicle from the ’80s with an FPV camera, along with a MKR WiFi 1010. The WiFi-enabled MKR board was linked with a second ‘1010, controlled by a (formerly) broken PS1 racing wheel.

    While old technology, this racing wheel is perfect for Arduino use, with steering, brake, and gas handled by potentiometers that are fed into analog inputs. The 2.4 GHz WiFi link between the MKR boards appears to work quite well when driving with an FPV headset, though “somehow” a wheel on the original car did manage to fall off during testing!

    Clem scored a broken steering wheel for the PlayStation 1 (yes the first one) at a flea market. Thankfully it is broken so he decided to turn it into an RC transmitter for his old Remote controlled Car! Learn how to use the Arduino MKR WiFi 1010 to make your own transmitter and receiver from scratch! It even supports FPV head tracking! What features would you like to add into the system?

    Nikodem Bartnik enjoys running, as well as making things, and he’s been able to combine both pursuits in the form of an ultrasonic race timer. 

    The device is placed at the finish line and mounted to a tripod. Once a runner gets into position, the start of the sprint is signaled with the beep of a small speaker.

    Everything is controlled by an Arduino Nano, while user feedback is provided via a small ePaper display. A pair of buttons also enable the runner to adjust the distance from 50m to 1km.  

    Although Bartnik is still no Usain Bolt, he’s planning to practice and hopefully improve his 100m dash time. Code is available on GitHub if you’d like to build something similar, along with 3D print files for the enclosure on Thingiverse.

    Pictures can be a great way to record an object or project, but typically only does so in one perspective. In order to capture things in three dimensions, you’ll need to be able to snap multiple photos and stitch them together with software.

    To take all the photos required for this process, “thomas_openscan” has come up with an automated device that rotates the object as needed, allowing him to capture images using a DSLR camera or even smartphone.

    An early prototype is shown here, which actually moves a phone around the scanned object. The later, more refined version manipulates the object itself using an Arduino Nano and a pair of drivers to control a pair of bipolar stepper motors. 

    More information is available here and over on Thingiverse, and can be purchased or built depending on your needs.

    When filming your projects—or day-to-day life—static shots can be fun, but having a moving perspective often looks even better. The challenge is keeping the camera pointed at your subject, which maker Saral Tayal addresses with his automated slider.

    This Arduino Uno-controlled slider is powered by a pair of brushed DC motors with encoders attached for feedback. One pulls the camera along a pair of rails on a set of linear bearings, while the other adjusts the camera’s horizontal angle using trigonometry to keep a particular object in-frame. 

    Code and print files are available in Tayal’s write-up, and some beautiful resulting shots with an explanation of the project can be seen in the video below.

    Rudimentary ultrasound machine made with Arduino Due

    Ultrasound images are an important tool for medical diagnosis, and while units used by doctors can be very expensive, getting a basic image doesn’t have to be. Inspired by this attempt at a $500 ultrasound machine seen here, maker “stoppi71” decided to create his own using a 5 MHz ultrasound transducer via a paint-thickness gauge.

    An Arduino Due provides computing power to turn sound pulses into images, while a 3.5-inch TFT display shows what it’s examining. Short pulses in the 100-200 nanosecond range are generated with the help of a monoflop and MOSFET, returning an echo corresponding to what it’s “looking” at. 

    Although the results are not nearly what you’d expect at the doctor’s office, rudimentary readings of skin and bone are definitely visible. 

    I’ve examined different objects from aluminum-cylinders over water-filled balloons to my body. To see body-echos the amplification of the signals must be very high. For the aluminum-cylinders a lower amplification is needed. When you look at the pictures you can clearly see the echoes from the skin and my bone.

    So what can I say about the success or failure of this project. It is possible to look inside the body with such simple methods and using parts, which aren’t commonly intended for that purpose. But these factors are limiting the results too. You don’t get such clear and well structured pictures compared with commercial solutions.

    This drink machine pours, slices, and dispenses mint!

    Arduino Team — April 18th, 2019

    Automated cocktail machines can be fun projects, but this device by CamdenS5 takes things to a whole new level. Not only can it pour liquids from multiple bottles, but it chops limes, dispenses sugar and mint, and even features a refrigerated compartment to keep ingredients at the appropriate temperature.

    An Arduino Mega along with an Uno are employed for control, while user interface is provided by an Android tablet affixed to the front of the assembly. 

    There’s a lot going on mechanically inside, including a linear actuator for chopping, and augers that dole out mint/sugar as needed. 

    Details on the build are available here, with code/files ready for download, and an interactive Fusion 360 model that you can manipulate in your browser.
