11 Arduino projects that require major hacking skills—or a bit of insanity

I will be posting more links to more interesting projects as comments to this post, like I did in my Cool uses for the Raspberry Pi posting. Some of the most interesting that spend some more time at can get their entire own postings this blog in Arduino section.

    Arduino Controlled Delta Robot © GPL3+

    It is about a delta robot that can grab and move objects. It is connected to a Raspberry Pi to play Tic Tac Toe using computer vision.

    Badland Brawler Lets Arduino Tackle Terrain

    For an electronics person, building the mechanics of a robot — especially a robust robot — can be somewhat daunting. [Jithin] started with an off-the-shelf 4 wheel drive chassis to build an off-road Arduino robot he calls the Badland Brawler. The kit was a bit over $100, but as you can see in the video below, it is pretty substantial, with an enclosed frame and large mud tires.

    Arduino Serial Data Directly Into Microsoft Excel

    Although 3rd party applications and plugins are available for port logging, it is possible to log data directly into Microsoft Excel through Visual Basic.

    There are no lack of applications tailored towards saving a .CSV file from an open port, which can then be imported into Microsoft Excel. For instance, GoBetwino, Processing, and Eltima Port Logger are useful and implementable strategies.

    However, it is possible to have Visual Basic (underneath Excel) listen to the serial port and output the data directly into Excel without requiring another program or plugin to load – in both Mac and PC versions.

    For Excel in Windows:
    Visual Basic connects directly to the COM port.
    Setting a faster baud rate in the PC macro works well.

    For Excel in OS X:
    For the Mac version of Excel, things are a little more complicated.
    I was unsuccessful in using a baud rate other than 9600bps with the Mac macro, even with the stty command in the terminal window.

    Turn Arduino Sensors Into Long Distance Industrial Sensors with Industruino’s 4–20mA.ker

    Industrino has unveiled their new universal 4–20mA sensor transmitter that allows you to take an Arduino-compatible 3.3V sensor and transform it into a long-range industrial counterpart.

    “The 4–20mA.ker is a universal Arduino derived 4–20mA sensor transmitter. It allows you to install 3.3V sensors in remote locations over a single pair of wires. This is achieved by transferring power to the sensor and data back to the receiver using a 4–20mA current loop.”

    Never forget to water your plants or turn off your grow lights. Never over or under water plants with water pump control and drip system.

    Well-Loved Toy Turned Into Robotic Glockenspiel

    If there’s a happier word ever imported into the English language than “Glockenspiel”, we’re not sure what it is. And controlling said instrument with a bunch of servos and an Arduino makes us just as happy.

    When [Leon van den Beukel] found a toy glockenspiel in a thrift store, he knew what had to be done – Arduinofy it. His first attempt was a single hammer on a pair of gimballed servos, which worked except for the poor sound quality coming from the well-loved toy.

    The improved instrument was then outfitted with eight servos, one for each note, each with a 3D-printed arm and wooden mallet.

    Automated DWC Hydroponic System

    This instructable’s aim is to teach people how to create a watering system from scratch.

    This is done by controlling the various factors that affect a plant’s growth through the use of a sensor and a smart mini-controller – such as Arduino Uno. By the end of this paper, you will be able to create a fully functional watering system for your plant.

    Making music with a keypad? Seems like a weird idea! But we will see with the good software, we can even make an electric guitar out of it!

    Arduino One Pixel Camera Sees All (Eventually)

    Taking pictures in the 21st century is incredibly easy. So easy in fact that most people don’t even own a dedicated camera; from smartphones to door bells there are cameras built into nearly electronic device we own. So in this era of ubiquitous photography, you might think that a very slow and extremely low resolution camera wouldn’t be of interest. Under normal circumstances that’s probably true, but this single pixel camera built by [Tucker Shannon] is anything but normal.

    At the heart of his unusual camera is the TCS34725 RGB color sensor from Adafruit which receives a tightly focused beam of incoming light by way of a 3D printed enclosure and a 3mm OD aluminum tube. This allows an Arduino Uno to determine the color of this tiny slice of light
