    CasioKeyBot plays electronic keyboard with automated fingers

    Arduino TeamOctober 8th, 2018

    Electronic keyboards have been around for many years, taking human input and translating it into a variety of sounds. In a strange twist on this technology, Igor Angst has decided to substitute a robot in to push the synthesizer’s keys, using a laser-cut finger setup controlled by an Arduino Uno.

    The MIDI sequence/notes to be played are supplied by a computer running ALSA (Advanced Linux Sound Architecture), and interpreted by a C program that translates it into USB serial signals that the Uno can use. It then actuates its wooden fingers, producing a pleasing tune along with apparently keyboard-provided accompaniment in the video below.

    I really like the crappy sound of those ‘80s toy keyboards. Unfortunately, I am a lousy live keyboarder and I only have so many hands. So I thought about adding MIDI capability to my good old Casio SA-21. The simplest way to do this is obviously building a robotized hand with 8 servo motors controlled by an Arduino microcontroller, which in turn receives its commands through the serial-over-USB interface sent by a tiny C application that connects to the ALSA sequencer world of my Linux live music setup.

    Laser cutter files are available on the project’s write-up and code can be found on GitHub.

    Twinky, the Arduino robot assistant

    Arduino TeamOctober 5th, 2018

    In the middle of a project, you may find that what you’re making is similar to something that’s been done before. Such was the case with Adrian Lindermann when he started constructing his “Twinky” robot and found the Jibo social bot had a similar design. 

    Like any good hacker, he pressed ahead with his build, creating a small yellow companion that can respond to voice commands via a SpeakUp click module, along with pressure on its face/touchscreen.

    Control is provided by an Arduino Mega, and Twinky can interact with other devices using a Bluetooth module. The robot’s head can even turn in order to point the display in the needed direction, and it’s able to play sound through an audio amplifier and speaker. 

    IT CAN SPEAK! PLAY MUSIC, SET TIMERS, ALARMS, TURN ON/OFF THE LIGHTS OR OTHER APPLIANCES. IT HAS A CALCULATOR AND A WEATHER STATION! DATE & TIME, BLUETOOTH 4.0, EVERYTHING WITH VOICE COMMANDS!!! And also with a touchscreen, it has one little motor so it can turn around when one of the two microphones hear you talk or make a noise.

    For more on this wonderful little robot, check out the project’s write-up and and build files here.

    Measure noise levels in your home with the Hello Light

    Arduino TeamOctober 3rd, 2018

    After realizing that asking his kids to keep the noise down was meaningless without some sort of standard, maker Jeremy S. Cook decided to construct the “Hello Light.”

    This cylindrical device measures sound with an electret microphone and an Arduino Nano, then commands a set of RGBW lights to progressively light up depending on the noise level.  

    In the end, the Hello Light eventually ended up as more of a game to see who could trigger the flashing volume limit warning—not particularly effective for its intended purpose. It does, however, make a fun interactive decoration, and also features a random lighting mode, and a slowly blinking white light setting.

    Code for the project is available on GitHub, and the build process can be seen in the clip below.

    MobiLimb is a robotic finger that plugs into your smartphone

    Arduino TeamOctober 2nd, 2018

    You’re constantly poking and prodding your smartphone throughout the day, but have you ever wondered what would happen if this little computer could poke back? Well now that’s actually possible, with the MobiLimb accessory by Marc Teyssier and a team stretching across two universities in France.

    The device uses an Arduino to interface with the phone or other smart device via its micro USB port, and powers a servo-actuated robotic manipulator with five degrees of freedom. The servos give the artificial finger enough power to pull the phone itself across the ground, and for other interactions like acting as a physical avatar, propping the phone up as a stand, or even taking input as a joystick apparatus.

    MobiLimb is a new shape-changing component with a compact form factor that can be deployed on mobile devices. It is a small 5 DoF serial robotic manipulator that can be easily added to (or removed from) existing mobile devices (smartphone, tablet). In the spirit of human augmentation, which aims at overcoming human body limitations by using robotic devices, our approach aims at overcoming mobile device limitations (static, passive, motionless) by using a robotic limb.

    This approach preserves the form factor of mobile devices and the efficiency of their I/O capabilities while introducing new ones:

    • The users can manipulate and deform the robotic device (input)
    • They can see and feel it (visual and haptic feedback), including when its shape is dynamically modified by the mobile device.
    • As a robotic manipulator, it can support additional modular elements (LED, shells, proximity sensors).

    More info is available in Teyssier’s write-up, and you can see it in action in the video below.

    At Jason Poel Smith’s local pediatrician’s office, they have a variety of movie posters and displays to help make the environment more welcoming to kids. The most popular of them all is a huge inflatable Baymax robot character from the Disney movie Big Hero 6. 

    While a beautiful display, Smith decided that what would make it even better is if it could talk, and went to work adding this functionality with an Arduino Uno, an MP3 shield, and a very large button. 

    Now when kids arrive, they can hit the button to hear Baymax welcome them to the office as their “personal healthcare companion” via a pair of powered speakers.

    Augment RC vehicle control with an IMU-based transmitter

    Arduino TeamOctober 2nd, 2018

    When piloting a vehicle remotely, it’s only natural to tilt your controller one way or the other to “help” guide it in the right direction. While usually this has no effect whatsoever, YouTuber Electronoobs decided to take this concept and run with it, creating a remote control transmitter that responds to an onboard MPU-6050 inertial measurement unit.

    The transmitter’s Arduino Nano takes movement data, and sends the corresponding signals to a custom receiver board on the RC car via a pair of HC-12 wireless modules. A second Arduino mounted in the car then commands the vehicle’s DC motors with the help of an H-bridge. 

    This is a radio controller that has 2 analog channels and the data is out from a MPU-6050 gyro module. So, we could control a toy car for example just by rotating the controller. I usually use the nRF24 module, but in this project I also want to show you how to use the HC-12 module. You will learn how to get the IMU data, how to use the HC-12 radio connection and how to control 2 DC motors using PWM signals and an H-bridge.

    It’s quite a versatile build, and it can even be set up to output PWM signals if you need to interface with more advanced electronics.

    Vintage ham radio transformed into epic party game prop

    Arduino TeamOctober 2nd, 2018

    Maker Thomas Meston needed a “mysterious looking device” that allows players to enter codes obtained via an original party game. What he came up with is entitled “Dr. Hallard’s Dream Transmission Box,” and consists of an Arduino, a party light, a smoke machine, and other components stuffed into a broken National NC-33 ham radio.

    This radio makes a really excellent enclosure for the electronics inside, and when the device is properly activated the winning team hears a special message via an Arduino Uno-controlled MP3 shield, accompanied by laser lights and smoke. 

    How it works:

    • When the box is switched on you hear static and see a yellow light. The device is ready for the codes to be entered.
    • Once all three dials have been set, the player switches the bottom toggle to “send” state, the box will message back whether team blue or team red has entered any codes with a quick flash of either a red or blue led.
    • If all three dials are set to red codes, the red team wins and hears a special message through the speaker just for them. The laser lights and smoke machine will be activated at the same time.
    • If all three dials are set to blue, a different message will play as well as activating the smoke machine and laser lights.

    More info on the project can be found here, and while it might seem like a shame to modify this kind of vintage equipment, Meston notes that he sees this as giving it a nice second life since it was previously non-functional.

    Custom “doorbell” flashes house lights for the hearing impaired

    Arduino TeamSeptember 28th, 2018

    Darren Lewis’ parents both have a difficult time hearing the doorbell. He experimented with an off-the-shelf flashing light, but found that could only really be seen when they were in the room—an obvious problem. In response to this, Lewis decided to make his own system that flashes multiple house lights at the same time.

    His device uses an Arduino Nano to detect the stock doorbell speaker voltage. When a press is sensed, it then activates a RF light switch via a modified remote, using an output pin and opto-isolator to substitute in for the normal button press. 

    It’s a clever hack, and certainly one that will certainly help alleviate doorbell frustration in the future!

    A dive mask or even SCUBA tanks are a great way to explore the ocean, but at depths of much more than 30 meters, things become a bit dicey. 1,000 meters is generally unthinkable for amateur divers but WorkshopScience has come up with a way to explore these regions without undue danger.

    His device, developed during an internship with Blue Robotics, is touted as the world’s first consumer deep-sea dropcam. It’s able to dive to 1,000 meters and capture 360° video, as well as pressure and temperature readings. 

    When a sufficient amount of time has passed, an Arduino board releases a weight by disintegrating a length of nichrome wire with electrical current. It then floats to the surface for data analysis. How it works, along with a resulting 360° video can be seen below.

  • Three-axis rotary machining with Arduino

    Three-axis rotary machining with Arduino

    Reading Time: 3 minutes

    For many years CNC machining was the purview of well-equipped shops and manufacturing facilities. With the availability of inexpensive control hardware, such as Arduino-based GRBL packages, this type of control has come to the (technically inclined) masses, enabling us to create complicated 2D and 3D shapes automatically.

    Normally, this means X, Y, and Z axes that control a cutting head, and if you wanted to much further in complexity and cost, you could add a fourth or even a fifth axis to tilt things as needed. The RotoMill, however, seen at World Maker Faire in New York, puts a different “spin” on things, substituting a stepper-controlled spindle for the Y axis. The result is a machine with unique machining capabilities, driven by an Arduino Uno running custom GRBL firmware.

    As for now, the CNC can easily mill parts out of softer materials like plastic, wood, and foam, although it is designed to cut aluminum as well.

    A three-axis rotary CNC built for the Mechanical Engineering senior design capstone course at Carnegie Mellon University by a team of engineering students. The CNC uses NEMA24 motors for each of the axes, with the X and Z axes actuated by lead screws, and the A (rotary) axis actuated by a worm gear. The spindle is an off-the-shelf Makita hand router, which allows for any router bit to be used.

    Each motor is controlled by a stepper motor driver, which are all coordinated by an Arduino Uno running a customized version of the GRBL firmware. This is in turn controlled by a laptop running open-source GCode sending software.

    To generate the GCode, we would create a 3D model of the part that we wanted to machine. We then “unwrapped” about the A axis. This basically takes the part and converts it from Cartesian coordinates to Cylindrical coordinates.

    To generate the GCode, we would create a 3D model of the part that we wanted to machine. We then “unwrapped” about the A axis. This basically takes the part and converts it from Cartesian coordinates to Cylindrical coordinates.

    At this point, we could take the unwrapped part and load it into Autodesk HSM, a popular industrial CAM package. This allowed us to generate a toolpath for machining the part. We basically “fooled” the CNC into thinking that it was a normal, three-axis Cartesian CNC. The trick, however, is that the Y axis is wrapped around and becomes the A axis.

    In several iterations of the Star Wars saga, small black droids can be seen scurrying around imperial installations. While they tend to fade into the background or provide a fun distraction in the movies, the mouse droid by Potent Printables acts as a sort of physical messaging app. It’s able to travel to the correct location, then pop open to unveil a scrolling LED sign.

    Potent Printables can trigger the side door using a Bluetooth app on his phone. On command, an RC servo pushes it open, and lowers it down using a stepper motor/reel setup. An Arduino Uno along with an Adafruit Motor Shield are used for control, while an HC-05 module enables communication with the system.

    Oscilloscopes come in all different shapes and sizes, and now with just a few discreet components, maker Peter Balch has been able to turn an Arduino Nano into an oscilloscope the size of a matchbox. 

    The simplest version of this device, which he calls the “ArdOsc,” displays data on a computer screen, but a 1.3” OLED can also be added if you want to use it on its own.

    His build write-up goes through several versions of the instrument, progressively adding capabilities including a logic display, signal generator, and other useful tools. It’s certainly worth checking out, whether you need tiny test equipment or just want to marvel at how something this small can be made!

    This oscilloscope costs the price of an Arduino Nano, plus a few pence for resistors, etc. Its specifications are:

    • Max 1M samples/second, min 1000sps
    • 8-bits per sample
    • DC 0-5V; AC +/- 550mV, AC +/- 117mV, AC +/- 25mV
    • USB “PC scope” or built-in display
    • Could be battery-powered

    Underneath the sea are a wide variety of strange and amazing animals. Perhaps none more so than the anglerfish, with its characteristic light-up lure in front of its face. Club Asimov decided to recreate this fish in a steampunk style, using a linkage system to actuate the tail, and another to open and shut its menacing mouth.

    Three stepper motors provide power for the fish’s movements, and two Arduino boards are used for control. Additionally, the fish’s lure illuminate to attract human observers, along with a heart that rhythmically lights up.

    Inspired by the steampunk universe and the anglerfish, the fish appearing in the movie Nemo, we present to you our newest invention” “Le Poisson des Catacombes!”

    The 1-meter-long mechanical beast is made with metallic pieces recovered from an old dishwasher. It reacts from movements around it giving the impression that it can interact with its surrounding.

    To make the fish, we used:

    2 Arduinos
    2 HC-SR04 ultrasonic
    3 Nema 17 stepper motors
    3 TB6560 stepper motor drivers
    5 red LEDs with 5 100 ohm resistors

The idea is that he could see this from anywhere in the desert, making it great for this particular event—and perhaps for later expeditions, such as beach camping.

    The robots were bent out of 1/8” steel wire, with single-color red LED strips affixed to it using zip ties. Three robotic panels are sequentially lit up using an Arduino and a bank of relays to form animations, similar to a neon sign. The flagpole used to raise the animated sculpture was affixed to his truck, creating a sturdy base as well as convenient source of 12V power.

    I wanted to make something so I could find our camp at night at Burning Man 2018. 2018 was a robot theme and I’m a fan of neon but no way was gonna head that route so I came up with an idea about a dancing cocktail glass kinda robot.

    We beach camp and have sand rails so I know how useful flying some kind of flag can be during the day and some kind of LED light pole is at night. So I figured, use it an burning man and keep using when we go to the beach.

    So using metal and welding is in my wheel house and I’m good with Arduinos so that’s the medium that I chose to implement this project in.

    Pay for art with your mugshot

    Arduino TeamSeptember 17th, 2018

    As reported here, digital artist Matthias Dörfelt has created an art vending machine in an attempt to increase awareness around blockchain possibilities, as well as how we handle our personal information.

    Face Trade, now on display at Art Center Nabi in Seoul, takes the form of a large vaguely face shaped box. When it detects a human in front of it, the installation invites the participant to swap his or her face for art, confirmed using a large yellow button that connects to the system’s computer via an Arduino.

    Once confirmed, Face Trade snaps the person’s picture and uploads it to a blockchain in exchange for a computer generated facial image. The resulting art’s conflicted expression is meant to signify the good and bad possibilities that can come out of using this technology. For their trouble, participants also get a receipt showing their captured headshot that now appears along with each transaction on itradedmyface.com.

    Face Trade consists of a camera flash, webcam, receipt printer, inkjet printer, computer, speakers, LCD screen, button and an Arduino (to control the button, LCD screen and camera flash).

    The main application that ties everything together is written in Python. It uses OpenCV to do basic face tracking and take the images. All the Ethereum related things were done using web3.py which is the official python version of web3 to interact with the Ethereum blockchain. The receipt printer, inkjet and Arduino are controlled via Python, too. The process is comprised of taking a picture, uploading it to the blockchain, passing the resulting transaction hash to the face drawing generator that uses it to seed the random numbers (so that each face drawing is uniquely tied to the transaction that it belongs to), printing the resulting drawing and finally printing the receipt.

    Ariadne Headband is a wearable device for haptic navigation

    In a new take on haptic navigation, makers Vojtech Pavlovsky and Tomas Kosicek have come up with a novel feedback system called the “Ariadne Headband.”

    This device—envisioned for use by people with visual impairments, as well as those that simply want to get around without looking down at a phone while walking or biking—uses four vibrating motors arranged in a circle around the wearer’s head to indicate travel direction.

    An Arduino Nano provides computing power for the setup, along with a compass module and a Bluetooth link to communicate with a companion smartphone app. The Ariadne Headband is currently a prototype, but this type of interface could one day be miniaturized to the point that it could be placed in a hat, helmet, or other everyday headgear.

    Project Ariadne Headband is made out of two parts: headband and control app. The common usage flow is following. First, you open Ariadne Headband Android app. Using this app you connect via Bluetooth to your Headband. Next, the app will ask for you current GPS location. Then you open Google Maps integrated into our app and select your destination (place where you want to go).

    Our Android app will compute the geographical azimuth from your current location and chosen destination. When you are ready you start navigating by pressing a button that sends computed azimuth to the Headband you put on your head.

    Headband consists of Arduino Nano board, GY-271 compass module, HC-06 Bluetooth module (we selected this module only for local availability and will switch to BLE soon) and 4 vibration motors. Compass module allows us to know current azimuth, that is where is the user looking. All components are placed into a small box on back of your head. Our aim in the future will be to make this as small as possible so you will not even feel it. It is also possible to place everything into a hat or helmet for example instead of rubber headband. We are using rubber headband because it is very easy to manipulate.

    Vibration motors around your head are placed in set directions so they can signalize where you should head. Your heading is computed by taking your current azimuth and the azimuth sent from android app (that is where you are currently going and where you should go, respectively).

    Let this Arduino robotic bartender mix you a drink

    Arduino TeamSeptember 14th, 2018

    We’ve seen different versions of robotic bartenders over the last few years, but this one by DIY Machines looks quite clean, and because of its battery-powered operation can be taken anywhere.

    The device works like a simple CNC machine, using a stepper and pulley setup to transport a glass between one of six upside down bottles. When it’s in the correct position, two more stepper motors push a lifting assembly into the selected bottle’s dispenser valve, emptying the correct amount of liquid into the glass. An Arduino Uno is used for control, with user interface provided via a Bluetooth module and smartphone app. 

    More videos and build instructions can be found in the project’s write-up, while Arduino code is available here.
