With the help of an Arduino, this dad turned a Wii Nunchuk into a wireless remote for a kid’s RC car.

The Wii Nunchuck has been a favorite control device for hackers since it’s debut in 2006. And why not, it has a simple design with a directional joystick, and can output signals via the I2C protocol. For this project, software engineer “trandi” used an Arduino Pro Mini to translate these signals into 9600bps serial signals needed for the wireless module he was using. The car is also hacked with a corresponding receiver, a TI Stellaris Launchpad, and a motor controller.

Perhaps what’s most interesting, however, is that it’s somewhat of a continuation of a project that he took on in 2013, repairing his then 18-month-old son’s toy car. Now several years older, maybe he has a new appreciation for this device and his dad’s skill! You can see more in trandi’s write-up here.

Space invaders played on a 16×2 character display

This Space Invaders game does more with less. [Rjk79] managed to make a video game using a two-line character display. The game consists of a wave of invaders on the top line, with the defender cannon on the bottom. The invader isn’t just stationary, but randomly moves to the left and the right. The image above captured a little bit of motion blur from the defender moving into position before firing on the enemy.

An Arduino board controls the 16×2 HD44780 character display. The game also includes sounds generated by the piezo buzzer seen on the breadboard. All the way to the right you can see the Wii Nunchuk breakout board which provides directional control and the firing trigger. If you want to recreate this one for yourself [Rjk79] is sharing the source code on Pastebin. There’s also a demo video found after the jump.

If you don’t have a character LCD on hand you might try this other Space Invaders clone that uses an 8×8 led matrix.
