Electric Eraser

Okay, This is pretty simple... I’m gonna tell you how to turn a mini fan (or some other spinning toy) into an eraser that will erase for you with precision.

There are many instances where you may need to erase things in a small area, and it may be difficult to do so when you are going back and forth with a standard eraser.

For example, you may want to erase a certain section.

You will usually end up with something like the bottom picture.


So, with this precision tool, you will be able to erase with precision, like the other picture.

Onto the directions!

Step 1: Get A Mini Fan Like This One

Electric eraser are great, but they are not always expensive (per someone's comment above). I have a Japanese Hinodewashi one http://www.jetpens.com/index.php/cPath/34_576 and it only cost $13.50.

LOL...few days ago i do something like this...it was very funny!

[rebladkins]

This is a great idea. You could use what ever eraser you wanted. An electric eraser is quite expensive, as much as $100 for one of good quality. Designers use them extensively. There are also eraser guards, cheap but handy. You will find them at Staples or whatever. Any drafting kit comes with a broom, 45*, 60*, and 90*, angles, three sided ruler, and eraser guards with various shapes.

I't would be nice to know wht this can erase. I recall 'ink erasers' which had grit in them, in order to remove paper (and the ink absorbed onto it). About as messy as Monkee-Mike's-Mum's-Tippex, but still a bit crappy. Will this drill holes through paper?

[NonPermissiveEnvironment]

It probably won't, but if the fan takes more than 2 AA's, it's more powerful than what I've tested. There may be other circumstances, though.

[NonPermissiveEnvironment]

maybe if I got one of those pen style eraser things and made the hole it comes out of bigger... And I don't have a camera yet, so :Þ to me.

[Robotrix]

this would work really well if used with eraser templates, which are thin sheets of metal with different shapes pierced out. It would eliminate the chances of rubbing out sutff close by if accuracy is Really important to you.

I'll stop with my stupid comments now

[zachninme]

And why not delete some of them?

[zachninme]

Most of those fan's motors are so weak that I don't think they would work... I am surprised they did!

[trebuchet03]

Idea seems good - I agree with Peter- B-, pictures of course would help (if you can somehow find a camera :P). That said, I have a rather nice electric eraser, if you make one that works with standard eraser refills (say the long type about 1cm thick) - that would earn an A+ ;)

Rotteneggs probably has more pyrotechnic stuff, I know a LOT about that

[PetervG]

"Repeat until the eraser bottom is almost touching the fan" meant to say the base of the spinner, but I'm sure you get it.

[NonPermissiveEnvironment]

Sorry about the lack of real pictures, I have a problem with my camera... It's nonexistent.
