Pocket Sized Electronic Eraser

Have you ever gone to a Smiggle shop and saw the electronic erasers?
You unhappily go home thinking how much you want it and wonder how to get the money.
Well that dilemma is finally over! Make this cheap small pocket-sized electronic eraser and save up to $10!

This is a entry to the pocket sized competition.

Step 1: Materials

You will need:
- a small electronic motor
- a push switch
- a 3 volt small battery (energizer cr2025)
- 3 wires (short)
- The case (I used a i-mini white out pen)
- masking tape
-and an eraser (obviously)

this is so weird i thought i invented that idea 5 years ago! right now im making a more advanced one its going to be called electro eraser ill post it soon and please vote!

[PikminRed]

Did you post that comment on every electric eraser instructable dude? These things were invented before you were probably born. Its just kids now days seem to not be able to erase stuff or.. they're just to lazy. Useful instructable though. I give them to people to sell.

What's smiggle?

[smeagle]

Its a shop that sells stationary that is very popular (smelly rubbers, electronic erasers, lava lamp rulers/sharpeners and ball through maze staionary)
http://smiggle.com/ is the website

[danm95]

oh, thanks for telling me ive never seen one.

[amakerguy]

nice idea.... I think someone could do better. add a plastic case and less bulky

[smeagle]

It isn't very bulky, about 5cm long and 4cm wide

[smeagle]

I changed it to eraser for less confusion ;)

[keng]

oh......an eraser......ahhhhh.....see "rubber" means something different in the states and the pic didn't make any sense with that definition.....an eraser.....k, got it.

[Javin007]

Right there with ya.

[zuixro]

Yeah, I was confused too...

[Marble of Doom]

I was thinking the same thing!

[Gypsyman]

yeah i was so confused about this....

[The Ideanator]

nope, I was thinking the same thing as you

[Padlock]

Haha.. That's exactly what I thought when I first saw it.
Suggestion to the author: maybe replace rubber with massager or some other synonym.

Pencil erasers do NOT make for good sex toys. especially when it's a high-speed rotating eraser. Eraser(or at least "Rubber(eraser for you yanks)") is definately the word we are looking for here.

[inventivefiend]

Yeah. I think rubber is the word they use in Australia. Perhaps the UK too.

I have not seen an electric eraser since the time when draftsmen actually drew plans on paper rather than cad systems. Wonder if it would be possible to flatten the tip of the drive shaft so it would grip the eraser better. Nicely done.

[ironsmiter]

A small dollop of epoxy in the eraser(Let it squish out a bit) or Superglue, should hold the eraser head just fine. When you need to replace the head, a little sandpaper should remove any last remnants of the old eraser.

ive never seen and electric eraser :o bit curious how well it works.

[dshadowy1]

Staedtler makes one. It is sitting right in front of me on my desk. It's great for drafting work.

[Berserk87]

just did a youtube search for em, work very good for small areas. where a normal eraser removes a lot and would take a fair amount of effort to get the small errors.
