    Smartphone thermometer
    https://hackaday.io/project/21689-smartphone-thermometer

    How to measure temperature using sensor, connected into smartphone headphone jack

    Not every smartphone has an thermometer so we decide to make one. Our temperature meter has -40°C to +100°C range and no external power is required. Phone sends an audio signal to power the temperature sensor. This sensor then generate the signal depending on the actual temperature. This signal is detected on the microphone input and through software calculate the corresponding temperature.

    Phone application is written in Android studio. It’s quite simple. After launch apk will turn on play inverted two channel 18kHz sinus signal in loop.

    Motor Vibration Monitoring with Bluetooth Sensor RuuviTag
    https://blog.ruuvi.com/monitoring-motor-operation-with-ruuvitag-df1a5739a926

    What we’re looking for?
    A lot of people ask us for some more advanced uses for accelerometer onboard RuuviTag. One such use is to monitor vibrations to determine if machine is on or off and even to do some predictive maintenance on machinery.

    My initial assumption is that we’re going to find two main frequencies of interest: The drum rotation at 600 RPM (or 10 Hz) and 50 Hz of European mains frequency. We’ll also want to take a look at the third harmonic of the mains frequency, which is at 150 Hz. To sample signal at 150 Hz, we’ll need to sample the accelerometer at at least 300 Hz according to Shannon-Nyquist theorem. The next value of LIS2DH12 onboard RuuviTag is 400 Hz

    Motor Vibration Monitoring with Bluetooth Sensor RuuviTag – Part 2
    https://blog.ruuvi.com/monitoring-motor-operation-with-ruuvitag-part-2-a089889887e6

    Data collection is simple continuation of the previous part, we collect data at 400 Hz and wait until first-in-first-out (FIFO) full interrupt comes from the accelerometer LIS2DH12. Then we read out the FIFO data, and calculate peak-to-peak (P2P), root-mean-square (RMS) and standard deviation (STDEV) of the data.

    Receiving the data
    The data is parsed with the Typescript / NodeJS collector made for the battery endurance testing and the code is run on Raspberry Pi. You can get the sources from Github

    Trying it out
    As before, we use laundromat as a household device to be monitored. A 3M VHB double-sided tape is used to attach the tag on the side of the laundromat.

    Conclusion
    We have now a simple vibration monitoring firmware ready for some field testing. If you’re willing to try it out the sources and compiled binary are on GitHub.

    Build a Parasite to Protect Your Privacy from Your Amazon Echo or Google Home
    https://blog.hackster.io/build-a-parasite-to-protect-your-privacy-from-your-amazon-echo-or-google-home-ecfca0348476

    Smart home assistant devices, like the Amazon Echo and Google Home, offer a lot of convenience, but that comes at a price. These devices don’t just fail to protect your privacy, they actively exploit it. They constantly gather data about you, and use it to tailor their advertising toward you. But, if you don’t want to give up that convenience altogether, Bjørn Karmann has a tutorial on how to build Project Alias and protect your privacy.

    ESP8266 And Alexa Team Up To Tend Bar

    After a hard day of soldering and posting memes online, sometimes you just want to yell at the blinking hockey puck in the corner and have it pour you out a perfectly measured shot of your favorite libation. It might not be the multi-purpose robot servant we were all hoping to have by the 21st century, but [Jake Lee] figures it’s about as close as we’re likely to get for under fifty bucks or so

    Yell At Your Desk To Get Up In The Morning
    https://hackaday.com/2019/02/05/yell-at-your-desk-to-get-up-in-the-morning/

    Standing desks are great conversation starters in the office – whether you like it or not. How do you know someone’s got a standing desk? Don’t worry, they’ll tell you. Standing desks have their benefits, but for maximum flexibility, many people choose a desk that can raise and lower depending on their needs. [Wassim] had just such a desk, but found pushing the buttons too 20th century for his tastes. Naturally, Google Assistant integration was the key here.

    [Wassim] started out intending to capture and then spoof the desk controller’s signals to the motors, before realising it was likely easier to simply spoof button presses instead. This was achieved through a handful of NPN transistors and an Onion Omega2+ microcontroller board. Then it was a simple case of coding the controller to press the various buttons in response to HTTP requests received over WiFi. Google Assistant integration was then handled with IFTTT, though [Wassim] also discusses the possibility of implementing the full Smart Home API.

    Control Anything With A Chat Bot
    https://hackaday.com/2019/01/05/control-anything-with-a-chat-bot/

    In the world of Internet of Things, it’s easy enough to get something connected to the Internet. But what should you use to communicate with and control it? There are many standards and tools available, but the best choice is always to use the tools you have on hand. [Victor] found himself in this situation, and found that the best way to control an Internet-connected car was to use the Flask server he already had.

    The remote controlled car was originally supposed to come with an Arduino, but the microcontroller was missing upon arrival. He had a Raspberry Pi around, and was able to set that up to replace the Arduino. He also took the opportunity to use the expanded functionality of the Pi compared to the Arduino and wrote a Flask server to control it, which is accessed as if you are communicating with a chat bot. Sending the words “go left/forward” to the Flask server will control the car accordingly, for example

    This Video-Streaming, ESP32-Based Robot Can Be Controlled Remotely via Web Browser
    https://blog.hackster.io/this-video-streaming-esp32-based-robot-can-be-controlled-remotely-via-web-browser-18005effa78d

    Back in 2017, engineer Max Kern created his Tiny ZeroBot — a simple robot built around the Raspberry Pi Zero W and featured a Pi Camera Module, DC gear motors, and other hardware packed into a 3D-printed housing. The robot could be FPV-controlled using any computer or smartphone via web browser. The ZeroBot was a simple, if not an ingenious design, that could be thrown together, and made for a great educational tool for anyone looking to get into robotics.

    Kern has since refined the robot’s design with a shrunken-down version of the ZeroBot, known as the ESP32 Wi-Fi Robot, which as the name implies, replaces the Zero W with a smaller ESP32 module.

    “Despite its lower processing power, the ESP32 robot has a ton of features. It streams color video over Wi-Fi, runs on a small LiPo battery, and can be controlled accurately from any web browser. With the €4 ESP32 and a €3 camera, it’s also really cheap.”

    This Alexa-Enabled Light Switch Takes a Physical Approach to IoT
    https://blog.hackster.io/this-alexa-enabled-light-switch-takes-a-physical-approach-to-iot-3484d6d00532

    If you buy a home assistant, like an Amazon Echo or Google Home, the first thing you’ll probably do is setup light control. It’s convenient to simply say “Alexa, turn off the bedroom lights” after you’re already nice and cozy in your bed.

    In short, they built an IoT servo-operated plate that mechanically flips a light switch. That’s obviously more complicated than a simple IoT bulb or smart plug, but it does offer one major advantage.

    Blink An LED On The Internet Of Things
    https://hackaday.com/2019/02/26/blink-an-led-on-the-internet-of-things/

    Blinking an LED is generally considered the hardware equivalent of the classic “Hello World” project. It’s a quick and simple test to show that you’ve got the basics worked out, and a launching point for bigger and better things. So why should it be any different in this glorious new Internet of Things era?

    The “WiFi HDD LED” created by [Limbo] is essentially just that, a status LED that can be triggered remotely thanks to the WiFi capability of the ever-popular ESP8266. Don’t think there’s much use for a wireless LED that blinks when your computer’s hard drive is thrashing around? Maybe not, but it’s definitely worth checking out if you’re looking for a good way to get your feet wet in the world of ESP hacking.

    Building A Simple Python API for Internet of Things Gadgets
    https://hackaday.com/2019/02/21/building-a-simple-python-api-for-internet-of-things-gadgets/

    t’s no secret that I rather enjoy connecting things to the Internet for fun and profit. One of the tricks I’ve learned along the way is to spin up simple APIs that can be used when prototyping a project. It’s easy to do, and simple to understand so I’m happy to share what has worked for me, using Web2Py as the example (with guest appearances from ESP8266 and NodeMCU).

    There are many valid ways to do this, but my first choice is Web2Py, a relatively easy to use open-source framework for developing web applications in Python. It supports both Python 2.7 and 3.0, although we’ll be using Python 3 today.
