Check out the new set-top box on the block, the NeTV from Chumby Industries. That link will take you to their video demonstration of the device, which is a humble-looking black box with no apparent user interface. You’ll see a few cool tricks that may impress you, like pairing the device with an Android phone through the use of a QR code. Once the two have mated you can do things like share images on the TV and load webpages from addresses entered into the smart phone. There are options for scrolling alerts when you receive an IM or SMS, and a few other bells and whistles. All of this from a device which connects with two HDMI ports to sit between your TV and whatever feeds it a video signal. Read all about the features here.

But its the hacking potential that really gets our juices flowing. The developer page gives us a look inside at the Spartan-6 FPGA that lives in the little case. We don’t often quote [Dave Jones] but we’re certain he’d call this thing ‘sex on a stick’. They’ve made the schematic and FPGA information available and are just begging for you to do your worst. The power for the device is provided by a USB connection but curiously is just above spec when drawing a max of 700 mA. We have a USB port on the back of our TV and would love to velcro this thing in place and power it from that. What would you plan to do with it?

So you bought yourself a Neato XV-11 and your floors have never been cleaner. The only problem is that you want to hack around with the hardware without losing your floor-sweeping minion. [Hash] found a solution to the issue by building a computer inside of the dustbin module.

You can see at the center of the image above a touchscreen. Normally this is just blank plastic, as it’s the removable container where your floor sweepings go, but [Hash] was inspired by the modular design. Since that bin is intended to be removable, it’s a perfect way to make add-on hardware removable. All he needed to do was find a way to connect to the Neato’s own electronics. The solution was a non-standard USB cable.

Using the guts from an Insignia Infocast 3.5 (he picked several of them up on clearance at Christmas) he  milled an opening for the touch screen, added a cooling fan, and wired up a toggle switch (not pictured above) which powers everything from the 14-17V coming in from that USB cable. The Infocast is a Chumby with a different branding so there’s plenty of Linux-based power and it’s WiFi enabled. Watch [Hash's] walk through video after the break to see all that went into this clever concept.

We haven’t seen too many hacks that make use of the Neato XV-11. [Hash] is the same guy who hacked the Lidar on the unit, but there must be others turning out impressive projects. Don’t hesitate to send in a tip if you know of one.

[Madox] gutted an Insignia Infocast to use with this robot. Insignia is Best Buy’s house brand and they partnered with Chumby to make their Infocast line. If you can find a used or clearance model it’s a great way to get yourself and embedded Linux board for a project like this one.

The body and wheels are 3D printed, with design files available at [Madox's] Thingiverse page. The mechanum wheels work amazingly well, using seven bearings each for smooth operation. The body itself includes a holder for two groups of batteries. One of those battery packs powers the Chumby board while the other is used to power the four servo motors responsible for locomotion. To simplify the electronics [Madox] chose to use a USB servo drive which only set him back about $20.

We’re not sure what the USB dongle on top of the robot is used for. We’d guess it’s a WiFi adapter, since the machine sets up its own access point to act as a controller. But we thought Chumby boards had WiFi built-in. At any rate, check out the video after the break where you can see an Android phone driving the little bugger. There’s a flaw in the code that prevents side-to-side movement, it gets fixed after a video break at about 2:15 and everything is peachy after that.

When [Bunny] moved into his apartment in Singapore he was surprised to find that a huge building project was just getting started on the other side of the block. Being the curious sort, he was always interested in what was going on, but just looking in on the project occasionally wasn’t enough. Instead, he set up a camera and made a time-lapse video.

This isn’t hard, you can find a slew of intervalometer projects which we’ve covered over the years. But being that [Bunnie] is one of the designers of the Chumby One, and frequently performs hacks on the hardware, it’s no surprise that he chose to use that hardware for the project.

Luckily, he’s sharing the steps he used to get Chumby capturing images. He mentions the hardest part is finding a compatible USB camera. If you have one that works with a 2008 Linux kernel you should be fine. The rest is done with shell scripts. Mplayer captures the images when the script is called from a cron job. Once all the frames are captured, he used mencoder to stitch the JPEGs into a movie. See the result after the break.

The Chumby One has an internal SD card offering a fair amount of storage. [Kenneth Finnegan's] came with a 1 GB card that had about 500 MB left over which he filled with a collection of MP3s. But he wanted to do more and so installed a pre-compiled version of lighttpd to act as a web server. The problem is that this binary requires a thumb drive to be plugged in because it maps the storage directory to the mounted USB folder. He wasn’t happy with that so he upgraded the internal SD card and rolled his own webserver to run from the internal SD card.

The upgrade involved going from a 1 GB to an 8 GB microSD card. In order to run the webserver internally he needed to recompile lighttpd to use a different root directory. This meant setting up an ARM cross-compiler and eventually finding a new place for the start up script. The location change for the ‘lighty’ directory leaves us wondering if a symlink couldn’t have solve the problem without recompilation. But we don’t have the hardware on hand to try this out ourselves.

But if you want to give it a shot, check out [Bunnie's] post about Chumby-based hardware. Looks like you can head out to the big-box store and have one in hand without shelling out too many clams.

[Eric Gregory] has gone a bit mad scientist on the Chumby, turning it into a bipedal bot. We expected all kinds of cool chumby hacking, but we can’t say we saw this one coming. [Eric] points out that with a 454Mhz processor, 64MB of RAM, 2GB of expandable storage and a USB host port, the Chumby is more than capable as a robotics platform.  With the addition of a mysterious and soon to be announced sensor board, he has made this chumby into a walking biped. While anyone who can write programs for linux, or even write flash applications can create software for the chumby, [Eric] chose to port the Robot Vision Toolkit over. This opens the doors to people who can write in Basic or who have written for the C64 or Apple][. You can see a video of this guy in action after the break.

The Insignia Infocast is a $169 simple media device being sold at Best Buy. Marketed as a way to share photos and run Chumby apps, hackers are starting to release packages to extend its features. [Bunnie] shows us one package in particular that allows it to be used as a web browser with an external keyboard. With an 800Mhz processor, an 800×600 touch screen, and 2 GB of memory, we can see that this is just scratching the surface of what is possible. [Bunnie] points out that some people are working on porting Android to the device, and if you really feel adventurous, you can dig into the hardware.

[bunnie] has taken a few moments to show us how to turn our Chumby One into a 3g router. As it turns out, there is an easter egg that allows it to communicate with certain models of 3g dongles. There’s no GUI for this trick, so you’ll be doing most of your configuration via SSH. That shouldn’t be a problem for this crowd though. The Chumby One just got a lot more appealing.

[Atlantageek] sent in a missile launcher project that he threw together. For Christmas he received a Chumby One and a ThinkGeek USB Rocket Launcher as gifts (lucky dog). Neither of these toys are “played with” in the traditional sense as much as they become centerpieces of your next hack. In that spirit, [Atlantageek] immediately wrote a widget to control the launcher via the Chumby. The side effect of driving his cat bonkers was an unexpected bonus.

[bunnie] posted this pretty slick way of getting composite video out of a Chumby. The Chumby is an open source connectivity device that has already seen some decent hacking. This modification, done by [xobs] isn’t too difficult. It only requires patching into some pads on the motherboard and loading a custom kernel to support the external output.

[Andrew Rapp] sent in this project called Droplet. He’s been doing work with Xbees and Arduinos together and built this little toy. He describes it as “sort of like a Chumby”. It has built in services for Twitter, Google Calendar, News, Gmail, etc.  You can download the full source code and plans on his site. His next planned revisions include possibly running it from a sheevaplug, making a nice case for it, and utilizing the unused pins of the arduino.

At this year’s Consumer Electronics Show, Chumby unveiled their latest prototype. It’s a network connected digital picture frame that runs Flash widgets. Just like the current Chumby model, they’re publishing the software and hardware under a license designed to let you hack it. They let us borrow one of their open chassis evaluation kits to teardown and photograph. We’ve got more pictures, full specs, and the schematics below.

The new version has an 800×600 LCD touchpanel. They’re still using an open source Linux backend, but they’ve updated the UI. Chumby widgets are now managed on the device. Before, users had to log into the website and then have their chosen widgets pushed down to the Chumby. The software is designed so that it could be a user’s primary photo management application. It instantly recognizes inserted memory cards and lets users drag and drop photos into the widget playlist. The device integrates seamlessly with PhotoBucket letting you easily upload new galleries. You can send these to other Chumby users (Chums) as well.

Keep in mind that this is just an evaluation kit, so it’s mounted in a generic wooden photo frame.

On the left side are stereo speakers connected to the onboard amplifier. The large orange ribbon at the bottom contains all of the display electronics. The lower connector on the right edge powers the backlight. The upper four wire ribbon is for the touchscreen. The cutout at the top is for the USB WiFi card. The coincell holder is battery backup for the real time clock. There are two control panel buttons along the top.

The board includes several headers to make debugging easier. The pins in the lower left provide a serial console (detail). The larger grouping is the CPU JTAG. Next to that is an MMC port for the initial boot image. The cryptoprocessor also has a JTAG connector.

Flipping the board over you can see the optional video camera daughter card.

The silkscreen next to the RAM on the front side says this board version is Stormwind v8.0 revC.

The front side of the board is where most of the interesting bits are. The reset and user buttons are located in the upper left. Next to that is an SD card socket and a CF card socket. The power jack and microphone are on the upper right corner along with the amplifier circuitry. Below the CF is a TSOP socket holding a Hynix HY27UF081G2A-TP memory device. Under that is the main processor, a Samsung S3C6410. It’s a 533Mhz ARM11 CPU. To the right of the chip, are two Hynix RAM chips. This new Chumby can be built with 2-8GB of storage. Below that is the Novatek NT39703 display driver. The crypto processor is left of there. The headphone jack is located in the lower right corner of the board. The board’s lower edge features three USB ports. A USB WiFi card is plugged into one of them. We assume not integrating WiFi means they don’t have to deal with FCC approval; they just use an approved card. The USB and memory cards are controlled by the Alcor Micro AU6350 located next to the camera module.

For those looking for even more detail, here are the full schematics:
