Introduction: Electro Eraser

Picture of Electro Eraser

This is a advance version of my electro eraser i thought of 5 years ago. Its going to be made in a project box from radio shack. What you need is a project box, high speed 9-volt motor, eraser, led, slide switch, potentiometer, velcro, 9-volt battery, resistor, and a 9-volt battery plug thing. Please vote for me in the Converse back to school in style contest. Please.Thanks!!!!!!!


Picture of WHAT YOU NEED

You need a L.E.D, a resistor, a potentiometer, a high-power 9-volt motor, a simple slide switch, and a dremel, and a lot of wires.

Step 2: Adding the Battery

first you must velcro on the battery to the side of the project box, and plug the thing on it.

Step 3: Drilling the Holes

Now you have to drill the holes for the motor wires with a dremel.

Step 4: Switch

Now you need to add the slide switch. It comes with screws so you drill two tiny holes, and one big rectangle for the switch to move.

Step 5: Add the L.E.D

Now you just have to make a tiny hole and insert the L.E.D from the bottom.

Step 6: Add the Potentiometer

Now you just need to drill a thin rectangle and stick out the potentiometer half way, and super glue the side to one of the sides.

Step 7: Solder!

Now you have to solder everything together, and this time add the resistor for the L.E.D.

Step 8: Super Glue the Eraser

Not only is this the most pointless thing in the world, but it's also the most AWESOME!

You could make this a lot shorter if you just jammed the eraser into the dremel chuck.

yes but that wouldn't be nearly complicated enough :-) very useless but fun project, i really recommend this as your first soldering project as it's quite easy, and to the author off this instructable: you might want to add some part-numbers as 'a potentionmeter' isn't nearly enough, that's like saying you need a resistor...
