THP Hacker Bio: IamTeknik

September 18, 2014 by Brian Benchoff 5 Comments

[IamTeknik]’s reason for entering his home automation assistant into The Hackaday Prize is simple; we have smart phones, TVs, and even smart cars. Why not a smart house?

Like its namesake from Iron Man, Project Jarvis is an intelligent assistant with a bit of home automation thrown into the mix. The hardware includes the usual relays and door locks, but that’s just the start of it. There’s also a personal digital assistant, living somewhere in the space between the hardware modules and [IamTeknik]’s smartphone. Here, voice recognition, speech synthesis, and a Siri-like functionality is the name of the game. Jarvis is capable of answering questions, compiling reports, reading social network messages, and automating everything connected to the main base station over the Internet.

[IamTeknic] has been busy studying computer systems engineering and of course working on his project for The Hackaday Prize lately, but he was able to sit down and answer a few questions for our THP hacker bio. You can check that out below, along with a few demos of what his personal Jarvis can do.

THP Semifinalist: The Moteino

September 3, 2014 by Brian Benchoff 16 Comments

One of the apparent unofficial themes of The Hackaday Prize is the Internet of Things and home automation. While there were plenty of projects that looked at new and interesting ways to turn on a light switch from the Internet, very few took a good, hard look at the hardware required to do that. [Felix]’s Moteino is one of those projects.

The Moteino is based on the Arduino, and adds a low-cost radio module to talk to the rest of the world. The module is the HopeRF RFM12B or RFM69. Both of these radios operate in the ISM band at 434, 868, or 915 MHz. Being pretty much the same as an Arduino with a radio module strapped to the back, programming is easy and it should be able to do anything that has been done with an ATMega328.

[Felix] has been offering the Moteino for a while now, and already there are a few great projects using this platform. In fact, a few other Hackaday Prize entries incorporated a Moteino into their design; Plant Friends used it in a sensor node, and this project is using it for texting and remote control with a cell phone.

The project featured in this post is a semifinalist in The Hackaday Prize.

THP Entry: Cut Energy Consumption By 30 Percent With This WiFi XBee Setup

Let’s be honest. Paying electricity bills sucks. The amount paid is always too much, and the temperatures in the building are rarely set at a comfortable level. But now, with the help of this DIY Climate Control system, power-users can finally rejoice knowing that the heating and cooling process of their home (or commercial space) can be easily controlled through the utilization of an XBee Remote Kit and a process called zoning.

The team behind the project is [Doug], [Benjamin] and [Lucas]. They hope to solve the inconsistent temperature problems, which are caused by a moving sun, by open-sourcing their work into the community.

Their XBee system runs on a mesh network making it a perfect tool for sensing and communicating which areas in the house are too hot or too cold. Once the data is collected, XBee modules route the information wirelessly to each other until it reaches a central Arduino gatekeeper; which then decides if it wants to heat, ventilate, or air condition the room.

Not to mention all the added benefits posted below:

Long Range Wireless Sensors For The Home-Area-Network

July 19, 2014 by Matt Terndrup 16 Comments

7785441404784533190 In the near future, we will all reside in households that contain hundreds of little devices intertwingled together with an easily connectable and controllable network of sensors. For years, projects have been appearing all around the world, like this wireless sensor system that anyone can build.

[Eric] hopes his work will help bring the truly expansive Home-Area-Network (HAN) into fruition by letting developers build cheap, battery-powered, long-range wireless sensors. His method integrates with the pluggable OSGI architecture and home automation platform openHAB along with using an Arduino as the lower power, sensor node that is capable of utilizing many types of cheap sensors found online.

[Eric]’s tutorial depicts a few examples of the possibilities of these open-source platforms. For instance, he shows what he calls a ‘Mailbox Sentinel’ which is a battery-powered mail monitoring device that uses a Raspberry Pi to play the infamous, and ancient AOL sound bite “you’ve got mail.” It will also send an email once the postman cometh.

In addition, he lists other ideas such as a baby monitoring sentinel, a washer/dryer notification system, water leak detectors, and security implementations that blast a loud alarm if someone tries to break in. All of this potential for just around $20.

The key to making this project work, as [Eric] states, is the MQTT binding that ties together the Ardiuno and openHAB platform. This allows for simple messages to be sent over the Ethernet connection which is often found in IoT devices.

So all you developers out there go home and start thinking of what could be connected next! Because with this system, all you need is a couple of ten-spots and an internet plug, and you have yourself a strong foundation to build on top of. The rest is up to you.

This open, connected device is [Eric’s] entry for The Hackaday Prize. You can see his video demo after the break. We hope this inspires you to submit your own project to the contest!

Kumo Connect: From Automated Desktop And Backyard Gardens To Automated Everything

July 16, 2014 by Kristina Panos 8 Comments

photo hut I ran into a guy at Maker Faire Kansas City who I used to scoop ice cream with twenty years ago. We were slinging frozen dairy at a Baskin Robbins in a dying suburban strip mall that had a one-hour photo booth in the parking lot. It was just far enough away from our doorstep that dotting its backside with the hard-frozen ice cream balls that had been scooped and then not always accidentally dropped into the depths of the freezer was challenging. This guy, [Blake], kept a hockey stick hidden in the back room especially for this purpose. I never could get them to fly that far, but he was pretty good at it.

I hadn’t seen him since those days, and there he was manning a booth at Maker Faire. He looked quite professional, showing no hint of the mischief from those days of ice cream hockey. His booth’s main attraction was Niwa, a connected indoor garden. Having spent four years living and working in Japan after college, [Blake] did not choose this name arbitrarily: ‘niwa’ is Japanese for ‘garden’. He loves Hackaday and was more than happy to share his story.

Connecting with Nature

[Blake] is an avid gardener, but his wife does not share this passion. A few years ago, he took a new job that required travel on an almost weekly basis, which meant big trouble for his plants. Unfortunately, he couldn’t find what he wanted to ensure they were taken care of. You know what comes next: he decided he would design his own system. However, he had no experience with electronics.

Hackaday Links: June 8, 2014

Yes, dogfighting with RC planes is cool. You know what’s even cooler? RC jousting. Considering these eight foot long planes are probably made of foam board or Depron, they’ll probably hold up for a fairly long time. The perfect application of RC FPV.

Home automation is the next big thing, apparently, but it’s been around for much longer than iPhones and Bluetooth controllable outlets and smart thermostats. Here’s a home automation system from 1985. Monochrome CRT display panel (with an awesome infrared touch screen setup), a rat’s nest of wiring, and a floor plan drawn in ASCII characters. It’s also Y2K compliant.

Here’s an idea for mobile component storage: bags. Instead of tackle and tool boxes for moving resistors and other components around, [Darcy] is using custom bags made from polyethylene sheets, folded and sealed with an impulse sealer. It’s not ESD safe, but accidentally zapping a LED with an ESD would be impressive.

Need a stepper motor test circuit? Easy, just grab one of those Polulu motor drivers, an ATtiny85, wire it up, and you’re done. Of course then you’re troubled with people on the Internet saying you could have done it with a 555 timer. This one is for them. It’s a 555, some wire, and some solder. Could have done it with discrete transistors, though.

Someone figured out Lego Minifigs can hold iDevice charge cables. +1 for the 1980s spaceman.

Remember that “electronic, color sensing, multicolor pen” idea that went around the Internet a year or so ago? It’s soon to be a Kickstarter, and man, is this thing full of fail. They’re putting an ARM 9 CPU in a pen. A pen with a diameter of 15mm. Does anyone know if an ARM 9 is made in that small of a package? We’ll have a full, “this is a totally unrealistic Kickstarter and you’re all sheep for backing it” post when it finally launches. Also, this.

HAL Is Duct Tape For Home Automation

HAL Home Automation

When it comes to home automation, there are a lot of different products out there that all do different things. Many of them are made by different companies, and they don’t often play very well together. This frustration ultimately led [Daniel] to develop his own Python based middleware solution to get these various components to work as a single cohesive system. What exactly did [Daniel] want to control?

First up was the door lock. [Daniel] lives in an apartment building, so there are actually two locks. First, a visitor must be allowed into the building by pressing a button on the intercom system in the apartment. Second, the apartment door has its own dead bolt lock that needs to be opened and closed. [Daniel] was able to control the building’s front door using just a transistor hooked up to an Arduino to simulate the press of the physical button. The original button remains in tact so [Daniel] can still easily “buzz” in a visitor.

The apartment’s dead bolt was a bit trickier. There are off-the-shelf solutions to control a dead bolt, but they are often expensive. [Daniel] built his own solution using a simple servo motor bolted to the door. The servo is controlled by the Arduino which is in turn controlled via two broken intercom buttons that already existed within the apartment. The buttons were originally used to either speak to or listen to a visitor before buzzing them into the building. They had never worked for [Daniel] so he re-purposed them for his own project. The whole DIY door locker is enclosed in a custom-made laser cut wooden box.

Click past the break for the rest of [Daniel’s] story.
