Keeping track your overall electricity usage is a good thing, and it’s even better if you know where all the kilowatt-hours are going. [Anurag Chugh’s] house has the three phases coming from the electrical distribution box tidily organized: One for the lighting and fans, one for household appliances, and one for the hot water supply. To monitor and analyze the electrical fingerprint of his house, [Anurag] installed a 3 phase energy meter and hooked it up to the internet.
20 students of the Eindhoven University of Technology (TU/e) in the Netherlands share one vision of the future: the fully domesticated drone pet – a flying friend that helps you whenever you need it and in general, is very, very cute. Their drone “Blue Jay” is packed with sensors, has a strong claw for grabbing and carrying cargo, navigates autonomously indoors, and interacts with humans at eye level.
If you just want to prevent your garden from slowly turning into a desert, have a look at the available off-the-shelf home automation solutions, pick one, lean back and let moisture monitoring and automated irrigation take over. If you want to get into electronics, learn PCB design and experience the personal victory that comes with all that, do what [Patrick] did, and build your own ESP8266 based irrigation controller. It’s also a lot of fun!
[Patrick] already had a strong software background and maintains his own open source home automation system, so building his own physical hardware to extend its functionality was a logical step. In particular, [Patrick] wanted to add four wirelessly controlled valves to the system.
Revolv, the bright red smart home hub famous for its abundance of radio modules, has finally been declared dead by its founders. After a series of acquisitions, Google’s parent company Alphabet has gained control over Revolv’s cloud service – and they are shutting it down.
Customers who bought into Revolv’s vision of a truly connected and automated smart home hub featuring 7 different physical radio modules to connect all their devices will soon become owners of significantly less useful, red bricks due to the complete shutdown of the service on May 15, 2016.

Home automation – the idea of a smart home that monitors and controls the inside environment, takes commands from occupants, and generally makes living easier. Hackers, makers, and engineers have been building their own vision of the smart home for decades. Thanks to cell phones and the revolution of the “internet of things”, home automation is now in the public eye. The hackers haven’t stopped though. They’re still building dreams, one circuit and one line of code at a time. This week’s Hacklet is dedicated to some of the best home automation projects on Hackaday.io!
We start at the top – [IamTeknik’s] Project Jarvis has been in the top five skulled and viewed projects on Hackaday.io for as long as we’ve been keeping records. Just like the fictional Tony Stark design which inspired its name, Jarvis is based on artificial intelligence. [IamTeknik] has created a system using the BeagleBone Black running his own custom software. He’s also creating Jarvis from the ground up – even the relay modules have been designed and built by [IamTeknik]. So far Jarvis has a great 3D printed door lock unit, and a really nice wall mounted tablet. We’re watching to see what modules [IamTeknik] adds next!
[Morrisonpiano] is no home automation noob. He’s been running his own system for two decades. HCS_IV Home Automation System is a project to update his HCS_C home automation system. For the uninitiated, the original HCS was created by [Steve Ciarcia] of Byte and Circuit Cellar fame. There have been several generations of the hardware and software since then, with plenty hackers adding their own custom features. [Morrisonpiano] is updating his system with an NXP Arm Cortex M4 CPU, three big Altera Cyclone FPGAs, and plenty of flash storage. Why use a FPGA on a home automation system? I/O of course! HCS uses a ton of I/O. There are 16 RS485 ports and 10 RS232 serial ports. Going with an FPGA makes things flexible as well. Want to add CAN bus? Just drop in some CAN HDL code and you’re golden!
[Steven] is giving the smart home more senses with Squirco Smart Home System – Sensor Network. Rather than just have a temperature sensor at the thermostat, or a motion detector in the front foyer, [Steven] wants a network of unobtrusive sensors to blanket the home. He’s doing this by replacing the common light switch with a smart module that has sensors for temperature, humidity, and human presence. [Steven] has spent quite a bit of time researching and experimenting microwave tomography as a means to detect humans. Going with microwaves means no obvious PIR windows.
Finally, we have [Ansaf Ahmad] with BeagleBone Black Home Automation. The idea for this project came from a calculus class on optimization. [Ansaf] is putting mathematical theorems to use in the real world by monitoring usage patterns and current demands of a device. With that data, he can optimize the usage to make things greener. So far, [Ansaf] has been experimenting with a lamp. The system has a web front end which uses PHP. The GPIO pins on the board are controlled using Python and Flask. As an early project, BeagleBone Home Automation is doing great – it’s already earned [Ansaf] high grades in his computer engineering class!

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!
Amyotrophic lateral sclerosis (ALS) is a debilitating disease that eventually causes the afflicted individual to lose all control of their motor functions, while leaving their mental faculties intact. Those suffering from the illness typically live for only a handful of years before succumbing to the disease. On some occasions however, patients can live for long periods after their original diagnosis, and in those cases assistive technology becomes a key component in their lives.
[Alon Bukai and Ofir Benyamin], students at Ort Hermalin Collage in Israel, have been working hard on creating an EEG-controlled smart house for ALS patients under the guidance of their advisor [Amnon Demri]. The core of their project focuses around controlling everyday household items using brainwaves. They use an Emotiv EPOC EEG headset which monitors the user’s brainwaves when focusing on several large buttons displayed on a computer screen. These buttons are mapped to different functions, ranging from turning lights on and off to changing channels on a cable box. When the user focuses on a particular task, the computer analyzes the headset’s output and relays the command to the proper device.
As of right now, the EEG-controlled home is only a project for their degree program, but we hope that their efforts help spur on further advancements in this field of research.
