Home Automation and Monitoring with Edison

[Tyler S.] has built a home automation and monitoring system dubbed ED-E, or Eddie. The name is an amalgam of its two main components, the Edison board from Intel, and some ESP8266 modules.

ED-E’s first job is to monitor the house for extraordinary situations. It does this with a small suite of sensors. It can detect flame, sound, gas, air quality, temperature, and humidity. With this array, it’s probably possible to capture every critical failure a house could experience, from burglars to water pipe leaks. It uploads all this data to Intel’s Analytics Cloud where we assume something magical happens to it.

ED-E can also sense the state of other things in the house, such as doors, with remote sensors. The door monitors, for example, are an ESP8266 and a momentary switch in a plastic case with a lithium ion battery. We’re not sure how long they’ll run, but presumably the Analytic Cloud will let us know if the battery is low via the aforementioned magic.

ED-E wins some style points for its casing. It’s a very well executed hack, and we’d not previously considered just how many awful situations can be detected with off the shelf sensors.

Hack Corporate Overlords For Single Button Beer Delivery

[Brody Berson] is at it again, but this time he’s hacked the services floating in the aether around him to give him beer on demand. Finally the future we’ve been waiting for.

This hack is not as hacky as his first one, which, at the push of a button, could summon a bad driver straight to his house who would then give him pizza. The first one was done with a modified version of a button used to summon paper towels; because there’s nothing like needing paper towels RIGHT NOW, and then pushing a button to get them a few days later.

Apparently Amazon saw how practically no one was pushing the dish detergent button, but a lot of people were making scary mailboxes and magic pizza apps after ruthlessly scratching the branding off. So they shrugged and decided to sell the buttons as the newly branded (these get more hilarious when you don’t use the acronyms) Amazon, Amazon Web Services Internet of Things Button. Now your button can die along with the internet because Amazon is hosting your Raspberry Pi for a small fee, neat.

Anyway, [Brody] did some research on the best beer delivery services in his area, and went with one called Drizzly because they had a nice API. After integrating this system with Amazon’s, he can now push a button and minutes later, after subtracting some currencies from his account, a bad driver will show up and hand him beer.

Hacklet 102 – Laundry Projects

Ah laundry day. The washing machine, the dryer, the ironing, and the folding. No one is a fan of doing laundry, but we (I hope) are all fans of having clean clothing. Hackers, makers, and engineers are always looking for ways to make a tedious task a bit easier, and laundry definitely is one of those tedious tasks. This week we’re checking out some of the best laundry projects on Hackaday.io!

laundrifyWe start with [Professor Fartsparkles] and Laundrify. Anyone who’s shared a washer and dryer with house or apartment mates will tell you how frustrating it can be. You bring your dirty laundry downstairs only to find the machines are in use. Wait too long, and someone has jumped in front of you. Laundrify fixes all that. Using a current sensor, Laundrify can tell if a machine is running. An ESP8266 monitors the current sensor and sends data up to the cloud – or in this case a Raspberry Pi. Users access this laundry as a service system by opening up a webpage on the Pi. The page includes icons showing the current status of each machine. If everything is in use, the users can join a queue to be notified when a machine is free.


borgmachineNext up is [Jose Ignacio Romero] with Borg Washing Machine. [Jose] came upon a washer that mechanically was perfect. Electrically was a different story. The biggest issue was the failing mechanical timer, which kept leaving him with soapy wet clothing. Washing machine timers boil down to mechanically timed multipole switches. They’re also expensive to replace. [Jose] did something better – he built an electronic controller to revitalize his washer. The processor is a PIC16F887. Most of the mains level switching is handled by relays. [Jose] programmed the new system using LDmicro, which is a ladder logic implementation for microcontrollers. For the uninitiated, ladder logic is a programming language often used on industrial Programmable Logic Controller (PLC) systems. The newly dubbed borg machine is now up and running better than ever.



Next we have [Michiel Spithoven] with Hot fill washing machine. In North America, most washing machines connect to hot and cold water supplies. Hot water comes from the home’s water heater. This isn’t the case in The Netherlands, where machines are designed to use electricity to heat cold water. [Michiel] knew his home’s water heater was more efficient than the electric heater built into his machine. [Michiel]  hacked his machine green by building an automated mixing manifold using two solenoid valves and a bit of copper pipe. The valves are controlled by a PIC microprocessor which monitors the temperature of the water entering the machine. The PIC modulates the valves to keep the water at just the right temperature for [Michiel’s] selected cycle. [Michiel] has been tracking the efficiency of the new system, and already has saved him €97!


laundrespFinally we have [Mark Kuhlmann] with LaundrEsp. [Mark’s] washing machine has a nasty habit of going off-balance and shutting down. This leaves him with soggy clothing and lost time re-running the load. [Mark] wanted to fix the problem without directly modifying his machine, so he came up with LaundrEsp. When the machine is running normally, a “door locked” light is illuminated on the control panel. As soon as the washer shuts down – due to a normal cycle ending or a fault, the door unlocks and the light goes out. [Mark] taped a CdS light detecting resistor over the light and connected it to an ESP8266. A bit of programming with Thinger.io, and [Mark’s] machine now let’s him know when it needs attention.

Drop me a message on Hackaday.io, and I’ll have your project washed, folded, and added to the list in a jiffy. That’s it for this week’s Hacklet. As always, see you next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

Roll Your Own Amazon Echo on a Raspberry Pi

Speech recognition coupled with AI is the new hotness. Amazon’s Echo is a pretty compelling device, for a largish chunk of change. But if you’re interested in building something similar yourself, it’s just gotten a lot easier. Amazon has opened up a GitHub with instructions and code that will get you up and running with their Alexa Voice Service in short order.

If you read Hackaday as avidly as we do, you’ve already read that Amazon opened up their SDK (confusingly called a “Skills Kit”) and that folks have started working with it already. This newest development is Amazon’s “official” hello-world demo, for what that’s worth.

There are also open source alternatives, so if you just want to get something up and running without jumping through registration and licensing hoops, you’ve got that option as well.

Whichever way you slice it, there seems to be a real interest in having our machines listen to us. It’s probably time for an in-depth comparison of the various options. If you know of a voice recognition system that runs on something embeddable — a single-board computer or even a microcontroller — and you’d like to see us look into it, post up in the comments. We’ll see what we can do.

Thanks to [vvenesect] for the tip!

YAGDO – Yet Another Garage Door Opener

It seems like every few months we cover another garage door opener, and the concept is quickly becoming the “Hello World” of DIY home automation. In this installment, reader [ray] made his own garage door opener and chose the ESP8266 as the wireless interface of choice, but spiced the application up with an ultrasonic sensor that detects whether the car is in the garage and a web app that shows history, plus integration with Blynk for remote access. For posterity, he made the project open source as well.

The video is well produced with lots of details and instructions, and the circuit board and assembly are refined and clean. It may be a “Hello World”, but it’s done right.

Some of the other garage door hacks we’ve covered in the last year include the fingerprint scanner opener, the IM-ME opener, the motion-based security opener, the cat-enabled opener, the OpenCV Pi opener, and a Bluetooth Low Energy opener.

Aquarium Light Mimics the Outdoor Sky

[OlegZero] has some pet fish in his basement, and decided to work on a little project for them — an aquarium light that mimics the outdoors. He calls it the FishLight project.

His goal was to create a light panel that could imitate the color of the outdoor sky (approximately) using an RGB LED strip. During normal operation, the LEDs cycle through the colors of day, from dusk to dawn using an ATmega88 microcontroller. After his girlfriend saw what it could do, she quickly came up with the idea to add a cityscape to the background to turn it into a piece of attractive decor for their home.

Still fail to see the point of going to this much effort for a few fish? Well, besides it turning into a rather nice artistic light for their basement, the concept can be applied to other animals as well. Like encouraging chickens to produce more eggs by making the days “longer” with artificial light. As it turns out chickens produce less eggs when the days get shorter — an easy fix with something like this!

Mirror Monitor Responds To Your Gestures

[DerVonDenBergen] and his friend are working on a pretty slick mirror LCD with motion control called Reflecty — it looks like something straight out of the Iron Man movies or the Minority Report.

Like most mirror monitors they started with a two way mirror and a de-bezelled LCD — but then they added what looks like an art gallery light off the top — but instead of a light bulb, the arm holds a Leap Motion controller, allowing gesture commands to be given to the computer.

The effective range of the Leap Motion controller is about 8-10″ in front of the display allowing you to reach out and point at exactly what you want — and then squeeze your fist to click. A complete gallery of images is available over on Imgur, but stick around after the break to see a video of the display in action — we kind of want one.
