Pink Eraser USB Flash Drive

Step 3 Free up the flash drive

The plastic case on my flash drive was easy to pull apart. Just work a fingernail between the pieces and pull it apart.

Once it's open you can behold just how tiny the real flash drive is.

Can't you just put the usb in whole?

[fungus amungus]

No, then you'd have to gut the eraser so that it was extremely thin, which is a pain and likely to fall apart.

[iamaspy]

 I cant even take apart the frame that covers the drive. D=
I have a kingston 2gb data traveller, help on taking it apart?

[BraisedDuck]

ok is urs the swiveling one or d one with d cap? if its the swiveling type, take out the outer case 1st using clipper or saw. if its cap type, u should notice a hole like notch on one side. using some plyers pry it apart

[soul_jahz_united]

does this in any way affect the circuit board? i.e. do fragments of the rubber disrupt the flow of power on the circuit? is there anything we could cover the circuit with before inserting into the pink pearl? lol, the pink pearl, i love it

[Derin]

no,the tracks are already covered by solder resist and the rubber wont affect the usb unless there are moving parts which i highly doubt

[zizou361]

I wrapped mine in 1 layer of Saran wrap just so it didnt get annoying rubber bits under the wiring. also it slides easier into a tight fitting eraser

[geeklord]

if your really worried, spray some plasticote on it

[puffyfluff]

No. The type of rubber in a pink pearl is non conductive.

[nerfer192]

lol...all rubber is non conductive

[puffyfluff]

Technically, all rubber is non conductive. But sometimes conductive materials are put in rubber to make it conductive.

[Loganeg]

correct only pure rubber is  non-conductive 

[nerfer192]

oh

[puffyfluff]

It's mainly for keypads-then they don't have to add conductive things.

[nerfer192]

oh like the mac keyboard?

[puffyfluff]

I don't know; I've never used a rubber mac keyboard. Usually they're for numbers, for things like doors.

[nerfer192]

oh i get it my sister gave me her build ur own phone kit and i was wondering how the rubber keypad actually typed

[mr_bandit]

Tear apart a remote control.

The key itself is a "hollow" rubber "cap". This allows the hollow base to collapse when the key is pressed.

Think of cupping your hand, palm down, on a table. A button push is like flattening your hand onto the table.

On the bottom of the key, inside the cap (think of this as a bowl) at the base (the deepest part of the bowl) is embedded carbon. It will not be as shiny as the rubber. (If you are still thinking cupped hand, it would be in the middle of your palm.)

The PCB where the carbon will hit looks like fingers on two hands that are flat on a table with the fingers alternating or interlaced.

The carbon makes a contact between the "fingers" of both "hands". There will be some resistance (as in Ohms law) that can be measured - it goes from an open circuit to a closed circuit. The resistance doesn't really matter at some point, it is less than an infinite (open circuit) value.

And - for normal rubber, any voltage/current strong enough to make it thru a rubber insulator will jusrt fry the rubber.

[nerfer192]

yes i noticed those fingers....thanks for the great explaination.

[puffyfluff]

Yes, that might be it.

[nerfer192]

okay

[DBLinuxLover]

High Voltage can make rubber conduct. Heck, high voltage can make almost anything conduct.

[puffyfluff]

True.

[Derin]

seconded

[macmccune]

thirded

[nedyah444]

fouthed

[Saturn V]

Fithified!

[red-king]

everything can conduct electricity. just some things more than others.

[puffyfluff]

Exactly.

[puffyfluff]

Just like how everything is poisonous, but the amounts at which they are harmful are different.

[Spaceman Spiff]

And everything gives off radiation

harder than it looks... tried it and came out crappy and off set. didnt mess with my flash drive, worked perfectly.. i eventually swapped eraser with a lego car looking thing. then made a a usb fan with legos around so you could add a switch and batteries. legos work really good, but i liked the idea of eraser, got me thinking about what to mod. thanks man
