Roll Away Clock Becomes A Programmable Rover

The parts laid bare in the picture above all make up a roll away alarm clock that flees when you don’t get out of bed. It’s an interesting idea, but considering most folks don’t sleep on hardwood floors we can understand why [TheRafMan] was able to pick this gem up for under $5. That’s quite a deal because there’s a very usable LCD module at the top. But for this hack, he focused on using the gearhead motors to make a programmable rover.

In order to make this programmable [TheRafMan] had to add a microcontroller. He chose an Arduino variant, called the Ardweeny. It’s a board that piggy-backs the ATmega328. But he didn’t use a stock Ardweeny; he’s altered it to play nicely with jumper wire. The uC is able to interface with the gearhead motors thanks to an L293D h-bridge motor driver chip. As you can see in the clip after the jump, the rover can now be driven around using a Wii Nunchuck or via a USB connection. If you’ve got a Bluetooth module lying around it wouldn’t be hard to make this a wireless solution that can be controlled with the accelerometers in a Wii remote.

Wii MotionPlus + Arduino

wiimoteplus

[knuckles904] was able to use the new Wii MotionPlus with an Arduino. Nintendo has released the WM+ in order to detect the motion of the controller better. The Wiimote only detects acceleration, whereas the WM+ detects rotation along 3 axes. The Arduino communicates with it over I2C, the same protocol that is used with the Nunchuk. To connect the two devices, he used jumper wires, but breakout boards are also available. He was able to create some example code with help from wiibrew.org. When paired with a Nunchuk, which contains a 3-axis accelerometer, you can have a 6 degrees-of-freedom IMU for under $40, perfect for controlling your robots or logging data.

Wii Nunchuck Controlled Servo Bot

[Stuart.Mcfarlan] is back. This time he has added Wii Nunchuck control to his servo bot. You may recall servo bot, or SERB, from a few weeks ago. Now the little bot can be controlled by either the joystick, or the gyroscope in the Nunchuck. Too bad its wired though, wireless is the next step right?
