Teddy Ruxpin: Navigate to 143 Main Street
https://hackaday.com/2018/06/04/teddy-ruxpin-navigate-to-143-main-street/
In the United States, TV and radio stations have to give the opportunity of equal airtime to all candidates. In that spirit, we thought we should show you [Jayden17’s] hack that puts Google Assistant into a Teddy Ruxpin.
Phone+Arduino Controlled Teddy Ruxpin
http://www.instructables.com/id/PhoneArduino-Controlled-Teddy-Ruxpin/
In this instructable I will be demonstrating how to control Teddy Ruxpin with a phone and the help of an arduino. After this modification Teddy Ruxpin will work as Google Assistant(or just about any other virtual assistant) and be able to lip sync voice recordings.
This is just a start on what I would like to do with Teddy Ruxpin. See “Stay Tuned!” step.

Deploying a Turnkey Raspberry Pi System
https://hackaday.com/2018/06/04/deploying-a-turnkey-raspberry-pi-system/
If you only do projects for yourself, you are spoiled. After all, you know your environment better than anyone. You know what power you’ll have, the temperature range, and how your network is configured. This last part is especially problematic if you are trying to deploy something that connects to a wireless LAN. How can you configure, say, a Raspberry Pi so that it can connect to an unknown user’s WiFi network? Fixing that problem is the goal of [schollz’s] Raspberry Pi Turnkey project.
The idea is simple. A Raspberry Pi image boots up for the first time and offers a WiFi hotspot itself called ConnectToConnect. The WiFi password is also ConnectToConnect. Once connected, you get configuration options that allow you to tailor the system to your network. Sure, you could have people log in and reconfigure via a serial terminal, wired ethernet (which isn’t always set up right, either), or a USB keyboard But that’s not a great out-of-the-box experience for most customers.

Ambient Lighting for Baby with the ESP8266
https://hackaday.com/2018/06/07/ambient-lighting-for-baby-with-the-esp8266/
There are plenty of great reasons to have a child. Perhaps you find the idea of being harshly criticized by a tiny person very appealing, or maybe you enjoy somebody screaming nonsense at you while you’re trying to work on something. But for us, we think the best reason for procreation is getting another excuse to build stuff. It’ll be what, at least two years before a baby can solder or program a microcontroller? Somebody’s going to have to do it for them until then.
To try to help his baby daughter get on a better sleep schedule, [Amir Avni] decided to outfit her room with some “smart” lighting to establish when it’s time for her to wake up. Not only can he and his wife control the time the lights come on to “day” mode, but they can also change the colors. For example, they can switch over to a red glow at night. Despite some learning experience setbacks, the both the parents and the baby are very happy with the final product.
An ESP8266 controls a WS2812 LED strip to provide the adjustable lighting, and a DHT22 sensor was added to the mix to detect the temperature and humidity in the baby’s room.

WiFi Pool Controller Only Cost $20
https://hackaday.com/2018/06/07/wifi-pool-controller-only-cost-20/
Pools have come a long way. It used to be you had a pump and if you were lucky it had a mechanical timer switch on it. That was it. Now you have digital controllers and spa jets and heaters. You can even get them that connect to your home automation system. If your pool isn’t new enough to do that already, you can get a range of add-on accessories. For a price. [Rob] paid $500 to get a remote for his pool. It wasn’t even WiFi, just a simple RF remote. In 3 years, the transmitter had burned out ($300 to replace) and he decided he had enough. For $20, [Rob] added MQTT control and monitoring to his pool using an ESP8266. You can see the video description of the project below.
Connect your pool to your smart home for $20 with Arduino!

BOOZER TELLS THE INTERNET HOW MUCH YOU DRINK (IF YOU WANT IT TO)
https://hackaday.com/2018/05/28/boozer-tells-the-internet-how-much-you-drink-if-you-want-it-to/
Over the past few years, Reddit user [callingyougoulet] has created Boozer, a DIY beer dispenser that keeps track of how much of your brew you have left in your kegs.
Inside the freezer is the Raspberry Pi and four flow sensors, each one connected to a GPIO port on the Pi. After some calibration, the Python code running on the Pi can calculate a pretty close estimate of the amount of liquid poured. There’s also a temperature sensor in the freezer, so that you can tell how cool your beer is.

Long-Range WiFi for the ESP32
A 1 kilometre line of sight range for the Espressif ESP32?
https://blog.hackster.io/long-range-wifi-for-the-esp32-9429ab89f450
a number of interesting extensions, from mesh networking to proprietary low-data rate, and long-range, extensions to the protocol.
Quietly added to the official development frameworks at the end of 2016, support for the proprietary 802.11 LR mode in the ESP-IDF made it into the master in January last year.
The 802.11 LR mode is a patented custom mode that can achieve a 1 km line of sight range so long as both the station and the soft-AP are connected to an ESP32 device. While these sort of ranges, and far more can be done with directional antennas and other hackery, this is an amazing accomplishment for an out-of-the-box board.
Enabling the mode is a simple function call, with no other changes to your code needed to flip your ESP32 into the LR mode.
Of course, what you’re sacrificing for additional range is data rate, the proprietary 802.11 LR mode designed for low-data rates

ESP GPS NTP Serve
A simple NTP server using GPS
https://hackaday.io/project/28013-esp-gps-ntp-server
Since creating some NTP based analog clocks I thought it would be handy to have a small accurate (GPS based) NTP server that could be deployed on the local network or as part of a stand alone network.
I’m thinking about trying to use an esp8266 again. I switched to the esp32 because software serial at 9600 baud gave a lot of watchdog resets, not what you want in a time server. Software serial was needed because the esp8266 has only one usable UART and that is used for programming and debug messages.

A YouTube Subscriber Counter With A Tetris Twist
https://hackaday.com/2018/06/19/a-youtube-subscriber-counter-with-a-tetris-twist/
When it comes to YouTube subscriber counters, there’s not much wiggle room for creativity. Sure, you can go with Nixies or even more exotic displays, but in the end a counter is just a bunch of numbers.
But [Brian Lough] found a way to jazz things up with this Tetris-playing YouTube sub counter.
He’s become enamored of the cheap and readily-available 64×32 pixel RGB displays, and borrowing an idea from Mc Lighting author [toblum], he decided that digits being assembled from falling Tetris blocks would be a nice twist. [Brian] had to port the Tetris-ifying code to Arduino before getting the ESP8266 to do the work of getting the subs and updating the display.

RESTful smart power plug
An open communication protocol smart power plug
https://hackaday.io/project/159067-restful-smart-power-plug
All smart power plug I found in the market uses proprietary communication protocol. They all connect to Internet passing through my firewall. I don’t feel comfortable to let any remote possibilities to hack into my IoT.
So I designed and built this RESTful smart power plug by using the bREST framework I wrote.
I uploaded ESP8266 specs doc. Go figure it out by yourself.
Note that I used a mechanical relay, instead of solid state relay. You can hear a click sound when you open/close. Depending on your load ( I probably will make the relay closed for a very long time ), solid state relay may need an additional heat sink to control heat build up. I don’t want to add it into this small junction box. So I choose the mechanical one.
Software
There is a popular RESTful framework in Arduino called aREST. But several things in aREST are foobar ( fuck up beyond recognition ). So I rewrote it from scratch. If you wonder why, read the README in my bREST framework.

Lighthaus is addressing the lack of earthquake early warning systems (EEWs) available to the American public.
We’re applying herd protection & data crowdsourcing to natural disasters. Physically, our devices will be small enough to fit in the palm of one’s hand. They will be plugged into the wall sockets of our customer’s homes and office spaces, monitoring the acceleration of the wall and streaming this data to our servers. When an earthquake strikes, our neural networks will first make certain that an earthquake is in fact underway. They will then immediately send warning messages to all sensors in the region of the incoming shockwaves.

No external server is required, only a bluetooth LE link between the phone and the Node. It provides a simple solution for an incredible number of everyday life situations, all this on a single CR2032 battery.
An Android application allows to find and configure nearby Triggy Nodes and to create rules between triggering events and actions to be performed. Combining it with IFTTT or a cloud connection, the possibilities become even wider: home automation, remote notifications, cloud automation… As an action, an HTTP webhook can be sent via WiFi and interact with your Raspberry Pi or ESP8266 projects.

It works by lowering a plastic weight down into the bin and, once the weight hits the grain, it lets weight off the micro-switch and instantly reverses a motor to wind the weight back in. The fishing line that’s attached to the weight is wrapped around a pulley that’s on the encoders shaft, the photon counts the pulses on the way down and on the way back up. it then takes the average number of pulses on those two runs, and converts them into ‘Inches that the weight traveled’.
