Well, a device which tells you that we’ve been rubbing it wrong, all this while. Here is an automatic board eraser which can do the job for you, without you moving from your place. It is a normal magnetic eraser with motors and wheels, which can be mounted on the board and do the task.

Here are the things you’ll need for this DIY:

• Arduino Uno R3

• 1Sheeld

• Micro Metal DC Motor Kit

• H Bridge Motor Driver

• Magnetic Disk

• LED

• and of course, the Magnetic Board Eraser.

 

Connect the hardware and upload the code to the Arduino. Yes, code is given in the link below. Open the 1Sheeld mobile app and connect it to the board, using Bluetooth. Select the game pad and accelerometer shield. Set the eraser on the board and you can navigate it using the arrows on your phone. You can also use it with your hand movement by using the accelerometer shield. You can signal the eraser to move in any direction using your hand.

It’s ok to be short, if you’re smart, we say!
