We have seen a few neat Google ADK projects pop up since its announcement a few weeks back, and this one is already on the list of our favorites.
YouTube user [chrisjrelliot] has put together a great hack demonstrating the ADK’s power and how easy it can be to control devices in real time with an Android-powered device.
He hacked apart an Android figure (naturally) and fitted it with some LED eyes as well as four servos. The servos are used to rotate the head, body, and arms of his Disco Droid, all of which can be controlled via his Android-powered tablet. As you can see in the video below, he is able to control the Droid’s actions in real time with a few simple swipes of his finger. One thing we did notice is that his tablet is not connected to anything via wires, so we are assuming that there’s a Bluetooth module hidden away somewhere in the mix.
While the video is a bit short on details, [Chris] promises that source code and build plans will be published in short order.
As a kid, [Wes] always dreamed of building a full-size, functional R2-D2 droid from Star Wars. While most youthful aspirations such as this fall to the wayside amid adult responsibilities and commitments, he did not allow his dreams to disappear along with his childhood.
He began his droid-building journey armed only with his dreams and some assistance from the friendly folks over at R2Builders. The entire replica was built using MDF, wood, and styrene sheeting, along with just one tool: a CNC machine. He walks you through the every step of the construction, stopping to give recommendations on CNC hardware, software, etc. along the way. He also provides Gcode files for each of the pieces he has constructed, which should be a huge help to anyone looking to build a R2-D2 clone of their own.
It looks like he is just getting around to fitting motors into the leg housings of his R2-D2 replica, but we can’t wait to see what it looks like once he has all of the electronics and other details finished.
If you are interested in more R2-D2 coverage, look no further than right here.
[Steve] wanted a dock for his Droid phone but couldn’t bear to put cheap-looking parts in his nice BMW. He decided to build his own in order to satisfy his functional and stylistic needs. His main goal was to have a dock with no wires showing, but it also needed to be removable and have the ability to work with different devices (GPS, Droid, etc.).
The hardest part of a build like this is matching the bracket system to the car’s interior. [Steve] sidestepped the problem by starting with a commercial mounting bracket made specifically for the BMW E90 series. From there he added the female half of a mounting bracket he milled himself. The male half connects to this part using an edge connector, passing signals and power between the car and whichever device is currently installed. This way he can design brackets for different devices and not change what’s in the car.
To get a closer look, check out the video after the break. The system he came up with looks wonderful and works great.

[Birdman] has managed to push a custom recovery image to the DroidX. This previously impossible action opens the doors to all kinds of fun hacking. While you can’t just drop a custom Rom on the phone right now, this is the first step in making that happen. You can find the directions in the post, but they’ve got a while to go before they become as easy as something like a jailbreak.
Standard connectors in portable devices would be great for the consumer, but then you wouldn’t purchase separate peripherals for ever portable you buy (lining the pockets of the companies licensing said peripherals). [Thijs] isn’t taking it lying down any longer. Realizing that the shape of the connector is one of the only things standing in the way, he built an adapter to use iPod docks with Droid. The hardware consists of a USB connector, audio jack, iPod connector, and a magnet. After working out the wiring it was just a matter of building a chassis using polymorph material. As you can see above, his expensive dock has no problem playing nicely with Droid because of his handy work.
There’s a simple hack to use your Motorola Droid phone as a USB host. It is a hardware-only hack that doesn’t require you to crack open your phone, root it, or even to change firmware (although device drivers in the stock Android image may be quite limited). The dongle above is used as a key to enable the mode while the phone is booting. This was repurposed from a car charging cable by removing the wires and resistor and shorting the resistor pads. Once the phone is in host mode the dongle is swapped for a simple USB-mini to USB-A socket adapter, built from two cables you probably have lying around. Now you can plug in any device you want.
We’re fans of pinch-zooming and that means multitouch. Although the interface is natively supported by both the hardware and operating systems of the Nexus One and Droid phones, it is locked out of the stock installation. You can make multitouch work on both handsets if you’re willing to do a little firmware alteration.
The coding has already been done for you, it’s a matter of loading a custom kernel. Both the Nexus One and the Droid have been rooted, and that’s what you’ll need to do to unlock multitouch with new firmware. In addition to gaining full access to the device OS, you’ll need to load up some different apps that support pinch zooming, etc. Luckily, these are readily available and you may like them better than the stock browser, maps, and photo applications.
