    3D Print a Home Automation Switch
    https://hackaday.com/2018/01/13/3d-print-a-home-automation-switch/

    The 3D printed switch fits a standard box and uses the guts of a Sonoff controller. These work with all the popular ecosystems such as Alexa and Google Home. And they are cheap. Like, really cheap. If you already have a 3D printer, even counting the cost of the filament these are going to be a small fraction of the cost of a commercial switch. You can see a video about the device, below.

    Solenoids and Servos for Self Actuated Switches
    https://hackaday.com/2018/01/18/solenoids-and-servos-for-self-actuated-switches/

    The new hotness in home automation is WiFi controlled light switches. Sure, we’ve had computer-controlled home lighting for literally forty years with X10 modules, but now we have VC money pouring into hardware, and someone needs to make a buck. A few years ago, [Alex] installed WiFi switches in a few devices in his house and discovered the one downside to the Internet of Light Switches — his light switches didn’t have a satisfying manual override. Instead of cursing the darkness for want of an Internet-connected candle, [Alex] did the only sensible thing. He installed electromagnets, solenoids, and servos behind the light switches in his house.

    Over The Air Updates For Your Arduino
    https://hackaday.com/2018/01/18/over-the-air-updates-for-your-arduino/

    An Arduino and a data radio can make a great remote sensor node. Often in such situations, the hardware ends up installed somewhere hard to get to – be it in a light fitting, behind a wall, or secreted somewhere outdoors. Not places that you’d want to squeeze a cable repeatedly into while debugging.

    Using the NRF24L01 chip with the Arduino is a popular choice to add wireless communications to a small project. By installing one of these radios on both the remote hardware and a local Arduino connected to the programming computer, it’s possible to remotely flash the Arduino without any physical contact whatsoever using Optiboot.

    MicroPython learns a new trick – ISP for AVRs
    https://hackaday.com/2018/01/18/micropython-learns-a-new-trick-isp-for-avrs/

    One of the reasons why the Arduino became so popular was the ability to program it with ease. It meant the end of big parallel programmers that would cost an arm and a leg. The latest installment of CircuitPython from [Lady Ada] and the team over at Adafruit is a library for programming AVR microcontrollers without a dedicated PC.

    Pepper Mill Locks Your Door
    https://hackaday.com/2018/04/02/pepper-mill-locks-your-door/

    Pepper! If you’ve ever tried to grind it, you’ve probably noticed it takes a bit of elbow grease. It’s actually possible to source electric pepper mills to grind it for you, in fact. It just so happens that [MarioM66] had one to hand, and a door lock that needed automating.

    Seeing as grinding pepper requires at least as much torque as turning an average key in an average lock, the electric pepper mill makes perfect sense to use as a lock actuator. This build actually uses the electric pepper mill to directly turn the key in the lock, courtesy of an adapter to couple the square output shaft to the key.

    The adapter was crafted out of a moldable plastic called MultiMorph.

    Sharpening with Bluetooth
    https://hackaday.com/2018/03/31/sharpening-with-bluetooth/

    Few things are as frustrating in the kitchen as a dull knife. [Becky] and her chef friend collaborated to build a Bluetooth module to tell you when you are sharpening a knife at the optimum angle. That might sound a little specialized, but the problem boils down to one that is common enough in a lot of situations: how do you tell your exact orientation while in motion? That is, with the knife moving rapidly back and forth over the sharpening stone, how can you measure the angle of the blade reliably?

    Most of what we see on the wearable tech front is built around traditional textiles, like adding turn signals to a jacket for safer bike riding, or wiring up a scarf with RGB LEDs and a color sensor to make it match any outfit. Although we’ve seen the odd light-up hair accessory here and there, we’ve never seen anything quite like these Bluetooth-enabled, shape-shifting, touch-sensing hair extensions created by UC Berkeley students [Sarah], [Molly], and [Christine].

    That’s what happened when [Ryan] decided to build a wireless “party button” for his kids. Tied into his Home Assistant automation system, a smack of the button plays music throughout the house and starts changing the colors on his Philips Hue lights. His initial version worked well enough, but in the video after the break, he walks through the evolution of this one-off gadget into a general purpose IoT interface he can use for other projects.

    Reprogramming Cheap WiFi Outlets
    https://hackaday.com/2018/04/16/reprogramming-cheap-wifi-outlets/

    If you want to retrofit your home with smart outlets and lightbulbs, bust out your wallet. You can easily spend forty dollars for a smart light bulb at your local home supply store, and strips of smart sockets could cost sixty. When [coogle] found a WiFi-enabled four-outlet power strip on Amazon, he couldn’t resist. Sure, the no-name strip would be locked down behind a stupid iPhone interface and will probably turn your house into a botnet, but never mind that: you can easily reprogram these power strips to be whatever you want.

    In my previous article, I explained how to set up a DIY Blynk Board using an ESP8266 based microcontroller. Blynk is an easy way to start creating Internet of Things projects. It’s not tied to any specific board, so you can use the platform to control Arduino, Raspberry Pi, and other hardware of your choice over the internet.

    Provisioning MS Azure and the MXChip for the Internet of Things with Chirps
    https://blog.hackster.io/provisioning-ms-azure-and-the-mxchip-for-the-internet-of-things-with-chirps-a25d1f8750a6

    Chirp started off as a mobile application, a platform for exchanging data using sound. Give the app a link, a piece of text, or an image, and it will “chirp” a sound which can be decoded by anyone else using the app and points to the data on Chirp’s servers. They then went on released an SDK enabling you to use Chirps to transfer data via audio on embedded devices like the Arduino.

    How to Detect Harmful Gases in Your Home with ThingSpeak
    https://www.designnews.com/gadget-freak/how-detect-harmful-gases-your-home-thingspeak/122909350259441?ADTRK=UBM&elq_mid=5631&elq_cid=876648

    Here’s how to use the open-source ThingSpeak platform to create a homemade detector for harmful gases like carbon monoxide.

    This project allows wireless monitoring of up to eight remotely located sensors using an HC-12 wireless transceiver and a simple protocol, which supports both outbound remote control and inbound status and data to be forwarded and displayed in a ThingSpeak platform. The project includes a remoted, Arduino-based, MQ-7 carbon monoxide (CO) sensor with a matching HC-12 transceiver. The idea is to provide a central D1 Mini, ESP8266-based monitor with local display and a ThingSpeak interface for detecting odorless propane, butane, and volatile liquids and fuels in facilities or even in your place of work or living.

    Several MQ series gas sensors are available for Arduino that detect many more common gases including CO, propane and natural gas, and ammonia (the MQ-37).

    The Arduino-based remote hardware takes care of the heater cycling and includes a DHT22 temperature and humidity sensor both reported and available to be used for the CO sensor calibration. The remote controller also provides the received request link processing over a HC-12 serial link. The HC-12 can be configured to any of 100 channels and can operate at over 1000 feet.

    That controller is coded to provide a scheduler and the WiFi uplink to the ThingSpeak platform. It uses a serial-based configuration to set up to six application-based parameters and receive up to four characteristics forwarded to the ThingSpeak. The HC-12-based link can be connected to any sensor or other remote applications supporting the link protocol.

    Graphical Programming for Your Own IoT Board
    https://www.hackster.io/Homer/graphical-programming-for-your-own-iot-board-1190c4

    Wanna have Scratch-style programming for your IoT board? Let me introduce you Entry, an open-source software that you can easily customize.

    Ladies and gentlemen, I would like to introduce you Entry, a Scratch-style graphical programming platform.

    From Entry homepage: Entry is an education platform created to help anyone learn to code. Students are able to learn to code while playing. Teachers are able to teach and manage students effectively.
    This open-source software program comes from Korea, developed and maintained by Entry Labs. It is written in HTML5 and JavaScript.

    The system architecture of Entry is quite similar to Scratch, except that here they provide an official Hardware Connector app for users.

    There are two core modules in Entry: Entry-js and Entry-hw.

    + Entry-js is the editor work-space module. If you want to create new programming blocks or modify user interface, you will need to check this module.

    + Entry-hw, or Entry Hardware Connector module, is used to allow Entry editor interact with hardware devices.

    By design concept, Entry editor can be loaded on web browsers, however, due to security reason, web browsers can not interact directly with serial COM port, so that’s why a hardware connector app is needed. They already supported tons of hardware devices in Entry-hw, but if yours is not on the list, you can add and define the communication interface for your device.

    Because with PHPoC device I am using, I can connect it with Entry editor via WebSocket (no security restriction tho), so there is no need of serial port connection neither Hardware connector app.

    Building a Sensor Network for an 18th Century Gristmill © GPL3+
    https://create.arduino.cc/projecthub/TotalJTM/building-a-sensor-network-for-an-18th-century-gristmill-d2f3b4?f=1

    Monitoring 100 year old factory processes are hard, but it gets easier, safer and more reliable with a network of nRF24L01 RF transmitters.

    The nRF24L01 module is a radio frequency transmitter that is capable of sending and receiving data to other NRF24 modules. The RF24 modules can be hooked up to an Arduino Nano

    RF24 modules can be powered at 5 volts but its recommended that you power it at 3.3 volts.

    The antenna modification boosts the range of a stock RF24 Module from a 5-10 foot range to 20 or 30 feet.

    To bring the system, each network needs a base node where all the data is routed too. In my project, I use a node connected to a Raspberry Pi over serial cable.

    Node and Base Programming
    For this project, I exclusively used the RF24Network library (created by Tmrh20) to handle the RF24 messaging. The RF24Network library allows you to structure a network of nodes in a tree structure.

    The larger objectives for my project are to take measurements inside a grain bin to figure out how full it is, monitor the 0-10v dc output of an AC Tech SMVector controller, and take temperature and humidity readings of various parts of the building.

    To measure the depth of grain bins, I installed ultrasonic sensors on the top of grain bins

    The DHT11 is used to measure temperature and humidity throughout the factory building.

    The network allows us to monitor the current remotely so if we see this value steadily rising, we can close the feeding mechanism manually before the mill begins to overload.

    Python Server Program
    After a message is sent from an RF24 node in the network, the message is routed to the base node (address 00) and is then sent, as a string, to a Raspberry Pi over a serial cable.

    an RF24 Network that could monitor different parts of our factory from one central place. Through the use of the RF24 module, Arduino Nano and various sensors I was able to complete my goal

    A prototype for Industrial IoT system to enhance warehouse/greenhouse monitoring using MKR GSM1400 and Hologram.

    Humidity and temperature monitoring is a very important factor in salt/dairy warehouses, greenhouses, as well as in homes. Instead of taking manual readings from digital meters, I plan to make a device which will automatically stream real-time statistics of warehouses (temperature/humidity) to the Hologram Cloud and ThingSpeak Cloud using Arduino MKR GSM 1400. By this way, we can get real-time result anywhere any time and take decisions on time to save products from damage.

    Voice Controlled Stereo Balance With ESP8266
    https://hackaday.com/2018/09/19/voice-controlled-stereo-balance-with-esp8266/

    A stereo setup assumes that the listener is physically located between the speakers, that’s how it can deliver sound equally from both sides. It’s also why the receiver has a “Balance” adjustment, so the listener can virtually move the center point of the audio by changing the relative volume of the speakers. You should set your speaker balance so that your normal sitting location is centered, but of course you might not always be in that same position every time you listen to music or watch something.

    [Vije Miller] writes in with his unique solution to the problem of the roving listener. He’s come up with a system that can adjust the volume of his speakers without having to touch the receiver’s setup, in fact, he doesn’t have to touch anything. By leveraging configurable voice control software running on his computer, his little ESP8266-based devices do all the work.
