[sparkfun] announced a new board called the IOIO (pronounced “yo-yo”) this week that allows communication from your Android devices to your upcoming projects.

The board hasn’t been released yet; [sparkfun] is still pulling together documentation and waiting on their first production run. We do know that the board contains a PIC24F MCU, and will give your phone analog input,  and Digital I/O, PWM, I2C, SPI, and UART control. Communication with the board is over the USB port on your phone.

The brilliant thing about this board is that an external programmer isn’t required. Everything you connect to this board can be controlled from within Android apps. We covered Android development in a hackaday tutorial series before, so now it’s possible to put these skills to give your projects a touch screen, internet and bluetooth connections, a camera, or your phone’s accelerometers. Very slick.

Video of some basic functions demonstrating what possible with this board after the jump, but feel free to comment and tell us what you’d like to see done with this board.

We’ve been on the prowl for a low-cost Android MID that, you know, works well. We were originally excited by the Eken M001 but early reports about poor battery life, coupled with the fact that it only runs Android 1.6 soured our interest. [Carnivore] didn’t let those things turn him away, instead he modified the M001 to meet his needs. He added a USB hub and flash drive inside as well as a few additional connectors for external devices. He’s also inserted a front-facing camera and improved battery life from a 1600 mAh capacity up to 5200 mAh. This means he can now depend on 7-12 hours of use depending on the power saving features he chooses. This does come at a cost, he had to add room inside the case so he annexed a project box for the back cover. As you can see above, he did a beautiful job of making it look right, but it’s lost that thin-sexiness it once had. See [Carnivore's] feature walk through after the break.

The Alex eReader has been rooted. This little handheld was the belle of the ball at CES 2010 when it came to eReaders. Now that is has been release into the wild it takes its place next to the heavy hitters that have already seen root access. If you’re unfamiliar, this device boasts a six-inch e-ink display and a 320×240 LCD touchscreen interface. Now that you can make it do your bidding, what are your plans for the $350 tablet? Let us know in the comments.

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.
