Magnetic Mouse Whiteboard Eraser

Step 3 Add magnets

Now to add a magnet so your board wiper will stick to your whiteboard.

I chose to use a magnet I obtained from a broken hard disk drive. They're incredibly strong and have quite a large area. One is plenty for this project. You'd be surprised at how many people have a broken hard drive lying around, ask around. Failing that, some strong neodymium magnets would do the trick.

Lay your magnet(s) on the bottom of the inside of the mouse, squeeze on a load of hot glue from your glue gun and allow to set. You could super glue instead, this can however be brittle when dry and may break with all the slamming against the board.
