    An Arduino Powered Tank Built To Pull Planes
    https://hackaday.com/2018/06/19/an-arduino-powered-tank-built-to-pull-planes/

    Surely our readers are well aware of all the downsides of owning an airplane. Certainly the cost of fuel is a big one. Birds are a problem, probably. That bill from the traveling propeller sharpener is a killer too…right? Alright fine, we admit it, nobody here at Hackaday owns an airplane. But probably neither do most of you; so don’t look so smug, pal.

    But if you did own a plane, or at least work at a small airport, you’d know that moving the things around on the ground is kind of a hassle.

    Using IMUs For Odometry
    https://hackaday.com/2018/06/17/using-imus-for-odometry/

    [Pablo] and [Alfonso]’s entry to the Hackaday Prize, the IMcorder.

    The IMcorder is a simple device loaded up with an MPU9250 IMU module that has an integrated accelerometer, gyro, and compass. This is attached to an Arduino Pro Mini and a Bluetooth module that allows the IMcorder to communicate with a robot’s main computer to provide information about a robot’s orientation and acceleration. All of this is put together on a fantastically tiny PCB with a lithium battery, allowing this project to be integrated into any robotics project without much, if any, modification.

    IMcoders
    https://hackaday.io/project/158496-imcoders

    IMU-based encoders. IMcoders provides odometry data to robots with a minimal integration effort, easing prototyping on almost any system.

    Tracked RC Tug Tows 5,000-Pound Airplanes
    https://blog.hackster.io/tracked-r-c-tug-tows-5-000-pound-airplanes-959106996c17

    While you may travel by plane, unless you’re a private pilot, you likely give little thought to how they get from the hanger to wherever they’re needed, or assume the pilot just “pulls it in” as you would your daily driver. While certainly capable of ground navigation, planes also need to be towed from time to time.

    Magnetic Spheres Link Up to Form Rotary Encoder Ring
    https://blog.hackster.io/magnetic-spheres-link-up-to-form-rotary-encoder-ring-5faaa786048e

    If you need to measure how far a shaft has rotated, an encoder is the way to go. But what if you actually wanted to build one yourself? As hacker “ao2” puts it, this solution involving a chain of magnetic spheres is likely an example of constraints driving its creativity.

    DIY Motorized Camera Slider with Pan and Tilt Head – Arduino Based Project
    https://howtomechatronics.com/tutorials/arduino/diy-motorized-camera-slider-pan-tilt-head-project/

    100% DIY, built with cheap materials like MDF and plywood and controlled using Arduino, three stepper motors, some buttons and a joystick attached on a custom designed PCB. Despite this, the end result is quite impressive, with super-smooth camera moves enabling us to get professional looking cinematic shots.

    So the three NEMA 17 stepper motors are controlled via the three A4988 stepper drivers. For controlling the slider movement we use a potentiometer connected to an analog input of the Arduino, and for controlling the pan and tilt head we use a joystick module which actually consist of two potentiometers, so it is connected to two analog inputs.

    Arduino EEPROM stores any datatype
    .get() and .put() make saving floats easy
    https://www.baldengineer.com/arduino-eeprom-stores-any-datatype.html#more-7381

    Funny how a simple idea can spider out into multiple paths. Arduino EEPROM seemed like a straightforward concept. A few a years ago it was as easy as having either 512 or 1024 bytes of flash memory. The Arduino IDE offered an EEPROM library which let you read and write a single byte. Today, however, with many different processor architectures saving data to EEPROM varies. It is now possible to save any datatype to EEPROM but not on all boards and not all using the same method.

    As if we didn’t have enough to worry about in regards to the coming robot uprising, [Ali Aslam] of Potent Printables has recently wrapped up work on a 3D printed robot that can flatten itself down to the point it can fit under doors and other tight spaces. Based on research done at UC Berkeley, this robot is built entirely from printed parts and off the shelf hardware, so anyone can have their own little slice of Skynet.

    Build Your Own Portable Arduino Soldering Iron
    https://hackaday.com/2018/07/09/build-your-own-portable-arduino-soldering-iron/

    At this point you’ve almost certainly seen one of these low-cost portable soldering irons, perhaps best exemplified by the TS100, a pocket-sized temperature controlled iron that can be had for as little as $50 USD from the usual overseas suppliers. Whether or not you’re personally a fan of the portable irons compared to a soldering station, the fact remains that these small irons are becoming increasingly popular with hackers and makers that are operating on a budget or in a small workspace.

    Believing that imitation is the most sincere form of flattery, [Electronoobs] has come up with a DIY portable soldering iron that the adventurous hacker can build themselves. Powered by an ATMega328p pulled out of an Arduino Nano, if offers the same software customization options of the TS100 but at a considerably lower price. Depending on where you source your components, you should be able to build one of these irons for as little as $15.

    Camera questions user, saves photographic response
    https://blog.arduino.cc/2018/07/12/camera-questions-user-saves-photographic-response/

    Cultural probes aim to elicit unique responses by asking people to respond to a question, many times in the form of a photograph. While disposable cameras once worked quite nicely for this purpose, their relative rarity today meant a new digital alternative was needed. For this, Interaction Research Studio came up with a series of ProbeTools that anyone can make and customize.

    The most basic type in this series of cameras is known as the TaskCam, which features a 3D-printed frame and an Arduino Uno at its core.

    Simple Digital Camera Designed for Cultural Probes
    https://blog.hackster.io/simple-digital-camera-designed-for-cultural-probes-e6ee0ff030c5

    When you need the correct answer to a straightforward question, context is very important. On the other hand, fragmentary responses to vague questions can provide insight into others lives, or perhaps inspiration for your own project that couldn’t be gotten either way. For this purpose, researchers developed “cultural probes,” devices that ask a somewhat vague question, and allow people to respond as they see fit — much of the time involving a photograph.

    Glasgow-based BitsNBlobs’ Piksey is the world’s smallest 328 Core development board that offers all the features and performance of the larger Arduino Uno but only at a quarter of the size. The fact that it’s breadboard compatible, and able to use all available Uno and Nano sketches, makes it a more attractive board over other tiny offerings on the market.

    “Magical” fountain bends time under Arduino control
    https://blog.arduino.cc/2018/07/16/magical-fountain-bends-time-under-arduino-control/

    Years ago, engineer and photographer Harold “Doc” Edgerton figured out how to “bend time” by pulsing a strobe light at the nearly the same speed as droplets of water, making them appear to move in slow motion, freeze, or even more backwards. Today, Nick Lim of jolliFactory has created the same effect, controlled by an Arduino Nano
