RAM Module Key Fob

Featured

In this instructable, I will show you how to, in less than twenty minutes, make a key fob out of an old RAM module. A key fob is one of those thingys that you get on a rental car saying the car model, make, name, plate number, etc.

This instructable is an entry for the pocket sized contest, so you know what to do if you like it(or even if you don't like it, you can proceed as if you had liked it).

This is also my very first instructable and would like some feedback on it. (Thanks)

Step 1: Your Supplies and Tools

Supplies & Tools:

Supplies:
An old piece of Random Access Memory
A keyring(preferably unused, but a used one is ok)

Tools:
Cutting Mat
Hobby Knife
Sandpaper 100 Grit*(a small patch is fine)(not shown in picture)
Drill wit a 1/8" bit(not always needed)

*Grit: the number of grains of sand in one square inch of paper(approx.). This means that the higher the number printed on the back of your piece of sandpaper, the finer the grains of sand will be.

Step 2: Preparation

In the following step I will show how to set up your workspace so as to be the most efficient possible.

To set up your workspace, you should consider the following:
How close do you want the sharp blade of the knife to our arm when not using it.
And how much elbow room you want to allot yourself.

Here is how I set my workspace up...

the knives on the side away from where my elbow will hit them and get cut(ouchyy!),
the ring that wont come in until later up and out of the way,
the sandpaper back and center so its easy to get at when I am ready to use it
remember, just don't breathe in any of the dust from the PCB and the components! PCB dust doesn't play nicely with your lungs _
PCB dust - Don't breathe this!

Don't go ripping out your 2GB DDR2 Ram Sticks people! lol it would be neat if you could store information on it, like a flash drive, but you would need a battery since these are Volatile memory and would lose data at a power outage.

That last memory translation is 64 bits of porn.
I'd plug that in my computer just to see what would happen!
probably not much... It could potentially crash, or even fry your computer.. The likely thing is that it will just give you a message on boot up saing that one of your ram slots is buggered. then you'll press the "any" key and it will boot normaly...
have happen me one time <_< one $%&$( sell me one that supose was good .... i wasnt ... that fry my computer
Awesome. I just found a bunch of old RAM, so I'll have to do this.

I learned not too long ago that you can also cut circuit boards pretty effectively using a guillotine-style paper cutter or even a pair of scissors.
really i would have thought that it would crack the board, i might have to try that out some time
ndinitz (author)  srhadaham5 years ago
It might crack if there is nothing holding the board down when the cutter comes down. but scissors, i doubt you would get enough leverage.
ndinitz (author)  randofo5 years ago
Yeah that would work too, but alas, I don't have one of those

Nice Instructable. Threw me off a little to begin with because i normally think of a "key fob" as an RFID tag, but a quick wikipedia search informed me that i was thinking of an "electronic key fob." Very clear instructions however, and a great home project for the "geeks" out there :)
