    Dr. Who’s Nemesis, The Dalek, Built With Arduino #ArduinoD14

    Arduino powered Dalek for all the Dr. Who fans. Designed by Andy Grove.

    After building the miniature robot Dalek earlier this year I decided to start work on a full size Dalek with the goal of finishing it in time for Halloween. Well, with just days to spare, I have completed the project. The construction took five months, with some time spent working on it almost every weekend. It is made primarily out of plywood, cardboard, and papier mache.

    The electronics were comparatively quick to put together. I have used an Arduino Uno to monitor two ultrasonic sensors in the base of the Dalek and send the results over the USB serial interface to a Raspberry Pi which then plays an MP3 clip. I used a separate Arduino board to provide sound to light functionality to drive the dome lights.

    I could have achieved the results I needed using just the Arduino or the Raspberry Pi but it seems to me that the Arduino is better suited to low level functions interacting directly with sensors and motors and so on, whereas the power of the Raspberry Pi is that it is a fully functional Linux computer for tasks requiring more computational power and where I can easily use existing skills to leverage the internet later on. Eventually I plan to put motors in the dome and a webcam in the eye so that the Dalek can look directly at people that approach. I also want to have a web interface to be able to control behavior.

    New to Arduino? It’s never too late to start! The Open Source Hardware Group offers a handy 14 part beginner course in Arduino. Check it out here!

    There is tons of information on the internet about Arduino including forums, tutorials, and project websites – it is overwhelming (and time consuming)! Especially when you are looking for a simple and concise introduction to the basics – many times, people assume too much electronics or programming background (or both), making it difficult to get anywhere.

    The Arduino Short Course for Absolute Beginners is a tutorial style collection of lessons designed to be simple and easy to follow which uses only the most relevant circuits and programs and assumes nothing about your prior electronics or programming experience.

    What you will Learn:

    • The basics of programming your Arduino
    • Just enough electronics to be dangerous
    • How to make your Arduino respond to sensors
    • How to build teleporters, levitating fortresses and nuclear reactors (maybe a stretch…)

    The course will cover the most useful, enlightening and simplest examples to get you started on the road to hacking just about anything.

    Arduino LED Light Show Projects from ASIMOWALK5 #ArduinoD14

    Matthew W shared a number of Arduino Light Show stages and projects in the Adafruit Google+ Community, documenting his exploration with this type of activity on
    his blog here. The video above was one of the last ones he created with his first adhoc stage as it was starting to show signs of age (according to him, at least), and checkout the videos below for videos from his second and third stages as well.

    From his Arduino LED Light Show FAQ:

    Q. What went into building the show?

    Talking about the latest show, there were a few key elements. It all started with two lines of breadboarded LEDs. The towers were constructed using cardboard and tissue paper to diffuse the RGB LED light in each tower. The “spotlights” were three servo motors with an RGB LED taped onto each servo horn. Behind the scenes was an Arduino Mega 2560 (compatible) along with three mini-breadboards to distribute power and to setup the resistors for some of the LEDs. Half of the wiring was 22AWG solid-core wire, the other half were female-to-male jumper wires.

    Q. Inspirations?

    World of Color at Disney California Adventure started it all. Canada’s Wonderland, my home park, upgraded their fountains over the past couple of years so that has also helped inspire me to continue. I also ran a short-lived (like they all are) website called More Than Starlight that was a blog and database for fountain and light shows. I discovered many amazing shows across the world which helped build up to my first light show.

    Those are pretty much all that’s been asked and worth noting… At least I have a post to reference if it’s needed….

    Hacking A Laser Tape Measure In 3 Easy Steps

    uni-t-laser-distance

    [Andrew] got a little help from his friends to hack a laser distance meter. Using laser distance meters as sensors is one of the great quests of hackers – with good reason. Accurate distance readings are invaluable for applications including robots, printers, and manufacturing. We’ve seen people try and fail to hack similar units before, while others built their own from scratch. [Andrew] started experimenting with the UNI-T 390B, a relatively cheap ($60 USD) device from China. He found the 390B has a serial port accessible through its battery compartment. Even better, the serial port is still enabled and outputs distance data. While data could be read, [Andrew] couldn’t command the 390B to start a measurement. The only option seemed to be using the Arduino to simulate button presses on the 390B’s front panel.

    In an update to his original blog,  he described an Arduino sketch which would decode the distance measurements. That’s when [speleomaniac] jumped in with the discovery that the Uni-T would respond to commands in the form “*xxxxx#”. Armed with this information, [Andrew] posted a second update with a basic command breakdown. Command *00004# will take a single measurement and output the data via serial. Command *00002# will take 3 measurements, outputting them in a C style array format. There are several other commands which output debug information and what appear to be stored measurement dumps. Although he didn’t explore every nuance of the data output,  [Andrew] now has enough information to initiate a measurement and read the result. Nice work!

    [Thanks James!]

    Open Ardbir: Homebrewing with the Arduino! #ArduinoD14

    NewImage

    As homebrewing becomes more and more common we keep running across new ways to do it. Here’s another one brought to you by MAKE using Arduino!

    Home-brewing can be summarised in the hobby of “make beer at home” and for sure is a wide spread passion all over the world including Italy where I live. Home brews are basically small scale craft beer makers and generally speaking people passionate not only in food and beverage but also DIY enthusiast that love experiments, recipe creation, row material transformation, process control and all the typical makers attitude.

    I don’t know if is the process of beer making, that is typically a step process with support of specific technology, or the typical mindset of the home brew, but as a matter of fact almost all home brewers are very proud of building their own instruments and equipment. In my long home-brewing experience I have found that one of the common passion in the community is the self-building and DIY of the equipment needed for beer production. In the many forums, blogs or magazines talking about the hobby there is almost always a section dedicated to DIY equipment…

    After many different experiment in the past with different technologies I came across the Arduino, and at least to me, it seems the 5th ingredient for beer making—together with water, barley malt, hop and yeast. The marriage of Arduino with brewing is perfect… perhaps because I live in Ivrea, not so far from the Arduino started.

    I tried first to port all my basic systems—based on standard off the shelf technology such as the PID thermo regulator, and PWM controller—into the Arduino ecosystem so that I can start other—more advanced—projects. During one of these initial projects I met another Italian guy who shared a similar passion passion for beer, the same ideas, and same love for the Arduino. Everything stared from a post of mine on an Italian blog… this stimulate people to enhance and develop my initial “all in one ” brewing system idea and from another similar Arduino-based project in Australia from Stephen Mathison.

    Thanks to the massive and fundamental contribution of Salvatore Petrone and Masimo Nevi I’m very proud to present Open Ardbir. It is a control system to fully automate the beer production process with a single vessel brewing system (RIMS).

    The core of the system is an Arduino Uno and a shield has been developed in order to connect temperature probe, the SSR relay for heating element, the Pump relay, and a buzzer, as well as an LCD display and 4 push buttons for interaction and programming.

    Dan Malec wrote up this great gaming tutorial for the Arduino on the Adafruit Learning System called Hunt the Wumpus:

    You can relive the early days of computer gaming on your Arduino with Hunt the Wumpus. This game is a particularly good fit for the RGB LCD shield:

    • Different screens can have different backlight colors
    • The LCD is large enough for selecting caves to move to or shoot into
    • The Wumpus, bat, and pit can all have custom characters
    • The D-Pad is well suited to handling menu navigation

    RGB LCD Shield Kit w/ 16×2 Character Display – Only 2 pins used! POSITIVE DISPLAY; This new Adafruit shield makes it easy to use a 16×2 Character LCD. We really like the RGB LCDs we stock in the shop both the RGB negative and RGB positive. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 3 to control the RGB backlight for a total of 9 pins. That’s half of the pins available on a classic Arduino!

    With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino! The best part is you don’t really lose those two pins either, since you can stick i2c-based sensors, RTCs, etc and have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle. (read more)

    Arduino Day is Today

    arduino-day-2014

    Did you know today is Arduino day? A day to pull that little teal board out of the bin and blink some LEDs or dive deeper to challenge your skills. There’s a map of local events, but unless you’re near Italy (the birthplace of the movement) events are a bit hard to find.

    There can be a lot of hate for Arduino around here, but we consider it the gateway drug to learning hardware design so why not support wide-adoption of the platform? We’ve even seen Hackaday-associated projects adopting compatibility. Both the Mooltipass and the FPGA shield projects have the platform in mind. Break down the assumption that electronics require mythical-levels-of-wizardry to toy with and we’ll be on our way to a world filled with hardware hackers. If you do want to get some really cheap boards to hand out Sparkfun has Pro Mini’s for $3 today, as well as some other deals [Thanks Jeff].

    Build Your Own Band Starting With A Robotic Controlled Drum Set #ArduinoD14

    NewImage

    Arduino-Controlled Robotic Drum via randofo

    For years I have been telling anyone who listens that I was going to build a robotic drum. Most people kind of shrugged indifferently. Even as I built it, most people kind of glanced over at it and conveyed doubtfulness. It seemed like no one but myself was convinced of just how awesome it was going to be.

    I received a lot of snarky comments about how I was making a strange annoying noise maker. When I finally go it set up for the trial run, I quickly silenced the naysayers. This robotic drum blew everyone away. I was finally able to convey my vision and explain why someone would ever want to build a robotic drum.

    The reason to build a robotic drum is because it is plain super-awesome. It keeps a beat like clockwork. You can slow down and speed up any drum beat with precision and ease. It can even play things a real human drummer could never do.

    I intend to use mine for rocking out. The current plan is to program it with different drum beats and play guitar along with it.

    I decided to use linear actuators (car door lock motors to be exact), and Arduinos with motor controller shields simply for ease of use and duplication. I am sure there are other more elegant ways to interface with the motors, but this is by far the easiest.

    From the Adafruit Learning System: Tiny Arduino Music Visualizer #ArduinoD14

      Tiny Arduino Music Visualizer: Maximum blinkenlights, minimum effort!

      Here’s an easy-to-build project that really packs a lot of blinkenlight for the effort: a little pocket-size music visualizer we call “Piccolo.”

      Set Piccolo next to the telly or some speakers and you’ll see the lights respond to music and sound — lowest notes toward the left end of the graph, highest notes toward the right.

      Technically this would be called a “spectrum analyzer,” but as this is not a precision scientific instrument, we’re more comfortable labeling it a “visualizer.” It’s strictly for show.

      This intermediate Arduino project shows a clear progression from input to processing and then output in a package that’s appealing and easy for minds to grasp: music and lights. It’s not abstract or “science-y” unless you choose to peel back the layers…

      Adafruit Bicolor LED Square Pixel Matrix with I2C Backpack: What’s better than a single LED? Lots of LEDs! A fun way to make a small colorful display is to use a 1.2″ Bi-color 8×8 LED Matrix . Matrices like these are ‘multiplexed’ – so to control all the 128 LEDs you need 24 pins. That’s a lot of pins, and there are driver chips like the MAX7219 that can help control a matrix for you but there’s a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn’t it be awesome if you could control a matrix without tons of wiring? That’s where these adorable LED matrix backpacks come in. We have them in three flavors – a mini 8×8, 1.2″ Bi-color 8×8 and a 4-digit 0.56″ 7-segment. They work perfectly with the matrices we stock in the Adafruit shop and make adding a bright little display trivial. It’s called a Bicolor LED, but you can have 3 colors total by turning on the red and green LEDs, which creates yellow. That’s 3 colors for the price of 2! Read More!

      Cheap Tire Sale Sparks Creative Contraption

      IMG_5541

      [Greg] and his kids were killing time at their (his?) favorite store — Harbor Freight. They noticed a sale on 10″ rubber tires for only $5/each… and it was all down hill from there.

      He started sketching up a general idea for a three-wheeled go-kart. Once he had a reasonable idea of what it would look like, he went down to the hardware store and picked up a whole lot of 1″ PVC pipe, tees, elbows, crosses, epoxy and fasteners.

      It’s a simple cart featuring a bit of a roll cage. Currently it’s just designed for being pushed around or riding down hills. It still looks like a lot of fun for the kids. We can’t help but wonder when he’s going to strap some electric motors on it to make it really fun for the kids. Maybe build a second, put some pool noodles around the frame, and bam, you’ve got a set of bumper-cars! If he needs any inspiration for the electronics, [Greg] could check out this Wireless Wii-Cart, or this over-powered-built-in-a-day-cart.

      Does the band rock? Find out with the Rockterscale #ArduinoD14

      The folks over at Radio 1 Interactive built a device powered by Arduino boards called the Rockterscale that can measure how much a band rocks.

      An idea popped out of Radio 1 Interactive a while ago. This would be a device that measures ‘rock’ – how much the band and the crowd are rocking at a gig – called The Rockterscale. It would display the amount of rock at the venue and on the web in real-time, maybe even showing it at other gigs and encouraging bands and crowds to out-rock each other. But, until now, no-one has really tried building it. But we were due another hardware hacking session so we decided to build the Rockterscale. Two intensive days later we had these…

      First, we have the Hat of Rock which measures the amount of head thrashing. Suitable for both fans and the band.

      Next, the dance floor measures movement and a force sensor hooked up to an improvised crash barrier at the front measures the crowd pushing up to it.

      A webcam mounted on the ceiling measures the overall crowd movement and then there’s the music itself. Audio processing code measures the loudness of the song and the spread of the frequencies in it – a high value would be a “wall of sound” like effect. It also does some beat detection. So we have 6 measurements and an equation…

      Hat + Floor + Crush + Crowd + Loud + Phat = ROCK

      Wireless Gardening with Arduino + CC3000 WiFi Modules with Tutorial on our Adafruit Learning System. Created by Marc-Olivier Schwartz

      In this guide, we are going to give a modern touch to gardening and connect some informations about your garden to the Internet. We are going to use a soil moisture & temperature sensor connected to an Arduino and a WiFi chip to automatically send measurements from your garden to the cloud.

      We’ll use a service call Carriots to handle the data and display it nicely on a webpage. Then, an email or SMS alert can be send to you automatically if the moisture falls below a given threshold.
      Don’t worry, you don’t actually need to have a garden or even plants (although we think plants are great to have) to use the content of this article: what you are going to learn can be used for any remote measurement projects. Let’s dive into the project!

      Arduino Uno R3 (Atmega328 – assembled)

      The new Uno is the latest version after the Duemilanove, with an improved USB interface chip. Like the Duemilanove, it not only has an expanded shield header with a 3.3V reference and a RESET pin (which solves the problem of how to get to the RESET pin in a shield) AND a 500mA fuse to protect your computer’s USB port, but ALSO an automatic circuit to select USB or DC power without a jumper! The Uno is pin and code-compatible with the Duemilanove, Diecimilla and older Arduinos so all your shields, libraries, code will still work. The new R3 (3rd revision) of the UNO has a few minor updates, with an upgrade to the USB interface chip and additional breakouts for the i2c pins and an IORef pin.

      Take your gardening project to the next level with a SHT-10 based soil sensor. The sensor includes a temperature/humidity sensor module from Sensiron in a sinter metal mesh encasing. The casing is weatherproof and will keep water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity (moisture) of the soil. It is designed to be submersible in water, but it’s always best to avoid long-term (over 1 hour at a time) submersion, if you need something that can be submerged for over an hour you may want to find a different sensor. It can also be simply placed outside for exterior weather sensing.

      Adafruit CC3000 WiFi Breakout with uFL Connector for Ext Antenna

      The CC3000 hits that sweet spot of usability, price and capability. It uses SPI for communication (not UART!) so you can push data as fast as you want or as slow as you want. It has a proper interrupt system with IRQ pin so you can have asynchronous connections. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP & AES. A built in TCP/IP stack with a “BSD socket” interface. TCP and UDP in both client and server mode, up to 4 concurrent sockets. It does not support “AP” mode, it can connect to an access point but it cannot be an access point.

      We wrapped this little silver module in a tidy breakout board. It has an onboard 3.3V regulator that can handle the 350mA peak current, and a level shifter to allow 3 or 5V logic level. This version of the CC3000 breakout does not have an onboard antenna – instead we placed a standard uFL connector so that an external 2.4GHz antenna can be used. You will need to purchase a uFL to RP-SMA adapter cable and a 2.4GHZ ‘WiFi’ antenna to use! See below for these items. This option can give you better range and makes it easier to enclose in a box. We use the same route and layout as TI’s eval board, however, this module is no longer automatically FCC certified when an external antenna is used.
