Spend enough time looking at home automation setups, and you’ll quickly find there are two competing philosophies. The first wants to put an Arduino on every light socket, with everything connected by cheap eBay radio modules. The second home automation philosophy requires astonishingly expensive hardware to talk to other expensive modules. The Arduino solution is a system that can be infinitely customizable, and the commercial solution talks to ‘the cloud’ for some strange reason. There is no middle ground. At least there wasn’t until [Eric] started poking around and looked at a few hardware solutions.
[Eric] was looking to control some GE Link bulbs through his phone, computer, or through the Internet. They’re supposed to be the best bulb on the market in terms of price and performance, but they can only be controlled with a Zigbee. This lead [Eric] to an interesting hack that gave all owners of the Wink Hub local control of their devices. From [Eric]’s research, this was the only way his lighting wasn’t dependent on ‘the cloud’.
Local control of the Wink was only possible after [Eric] read a post on rooting the Wink (and this post from a few days ago). Because the device could be rooted, and the fact that [Eric] already has a few things in his house integrated with OpenHAB, the choice on how to proceed with controlling a few Zigbee enabled lights was easy.
Once [Eric] got the light bulbs talking to the Wink, integrating them with the rest of the devices in his home was easy. The new bulbs are activated with his Arduino motion sensors, door sensors, and can be controlled via smartphone or by voice control. The Wink can also be completely disconnected from the Internet. A good idea, because the ability to turn a light on and off should not be dictated by the quality of your Internet connection.

If you’re looking for Home Automation appliances, you might want to check out the Wink Hub. It’s fifty bucks, and has six radios on board: WiFi, Bluetooth, Z-Wave, Zigbee, and 433MHz Lutron and Kidde. That’s an insane amount of connectivity in a very cheap package. It’s been pwnzor3d before, but dinnovative has a much better solution for getting root on this device.
Earlier methods of rooting the Wink involved passing commands via URLs – something that’s not exactly secure. The new method leverages what’s already installed on the Wink, specifically Dropbear, to generate public keys on the Wink hub and getting that key onto another computer securely. The complete exploit is just a few lines in a terminal, but once that’s done you’ll have a rooted Wink hub.
Even though the Wink hub has been rooted a few times before, we haven’t seen anything that leverages the capabilities of this hardware. There isn’t another device with a bunch of IoT radios on the market for $50, and we’re dying to see what people can come up with. If you’ve done something with your Wink, send it in on the tip line.
When looking for a remote control for your next project, you might want to look in your living room. Wii controllers are a hacker’s favorite, but wagging an electronic wand around isn’t the greatest for remote control planes, cars, tanks, and multicopters. What you need for this is dual analog controls, something every playstation since the 90s has included.
[Marcel] created a replacement electronics board for the Sony DualShock 3 controller for just this purpose. With this board, an XBee, and an old controller, it’s easy to add dual analog control and a whole lot of buttons to any project using an XBee receiver.
The replacement board is based on the ATMega328p uC, includes a Lipo charge circuit and power supply, and inputs for the analog sticks and all the button boards inside the DualShock controller.
Yes, we have seen an earlier version of [Marcel]’s project before, but this time he’s added a few new features – the rumble now works and thanks to multiple people unable or unwilling to spin a few boards, [Marcel] has put up an Indiegogo campaign.

Wardriving started out as a search for unprotected WiFi access points before hot spots were prevalent. And so this ZigBee protocol wardriving hardware which [Travis Goodspeed] put together really gives us a sense of nostalgia for that time. Don’t get us wrong, we love our pervasive WiFi access and don’t wish to go back to simpler times. But if the radio signals your looking for are scarce, locating them provides a challenge.
Regular readers will recognize that [Travis] is interested in all things RF. One of his projects included sniffing wireless keyboard packets out of thin air and displaying them on the screen of his Nokia N900. This is right along those lines but he’s upgraded to an N9 phone for the display hardware. He switched up the RF hardware, using a TelosB (a board he’s already familiar with) to get on the 802.15.4 ZigBee spectrum. This dev board has an expansion port which let him use an RN42 module for wireless communications with the phone. This means the sniffing hardware can be hidden away in a backpack or jacket. After all, nobody will question someone walking around staring at a smart phone.
Here’s a bulky tutorial that will round-out your understanding of ZigBee wireless communications (translated). The protocol is great for hobby electronics projects because it uses low-power short range wireless devices to build a mesh network. The guide covers both hardware and software, but also takes the time to explain what that hardware is doing in the background.
As you can see, several different renditions of an XBee module are used as examples. They pretty much all rely on a series of SparkFun breakout boards that each serve different purposes. Once you’ve acquired these modules, there’s a fair number of choices needed to configure them to play nicely with each other. We read most of the tutorial (we’ll save the rest for later enjoyment) and had no problem following along even without owning the hardware or being able to use the interface as we learned.
Whenever we cover XBee modules we always like to mention that it’s quite easy to use these for remote sensors with no additional microcontroller needed.
The Zigroller is a Zigbee remote-controlled balance bot. Although balance bots have been featured on [HAD] before, the Zigroller appears to be well-built and the project is well documented. Besides a section on hardware, the software for this build is documented here. The theory behind a balancing bot like this is given in this [MIT] paper if you’d like some more background.
The roller itself was conceived as a project for a UW class this summer. The class was about control theory, so the electronics and mechanical setup was copied off of the [ArduRoller] project. In order to keep this project from influencing the control code of this ‘bot, it’s claimed that the code was not looked at while writing the new software. The process for building the remote control assembly is nicely documented and is an original creation for this project. Check out a video of it in action after the break!

[Russell] sent in a neat home automation project he’s been working on. Even though the project only has two devices so far, we can already see the potential of his project.
Instead of the X10 standard that has been a staple of home automation for more than 30 years, [Russell] went with ZigBee modules. Aside from being much faster and more flexible than X10 home automation modules, ZigBees also open up a bunch of projects that would be impossible if he went with X10. With some well-placed IR transmitters hidden in his living room, it would be possible to have a TV and cable box controlled via the Internet.
So far, [Russell] built an network-controlled RGB ‘mood lamp’ and an infrared remote for his central air. Everything is controlled through a web app, and [Russell] says that additional modules can be easily added to the code.
Check out [Russell]’s demo of his project after the break.
