Make Your Own Roll-Up Keyboard




Introduction: Make Your Own Roll-Up Keyboard

Have you ever wanted one of those pricy roll up keyboard but didn't want to spend the money? Here is a quick and dirty way to make your own.

Step 1: Tools & Materials

For this project you will need:

1 USB Keyboard
1 Screw driver with interchangable bits
Handful of small project sized nuts and bolts

Step 2: Deconstruction

Using the screwdriver deconstruct the keyboard.

Step 3: More Deconstruction:

Remove the keyboard's membrane switch pad and control board. The membrane consists of 3 separate layers tacked together.

Step 4: Assembly:

Using the rubber pad, plate and nuts & bolts, reassemble the membrane to the control board. Make sure that the traces of the membrane line up with the traces on the control board. If your keyboard had a socket and ribbon cable just reinsert the cable and you ready to label the keys.

Step 5: Complete:

After the long process of labeling the keys you are now ready to use your roll up flexible keyboard. Using a text editor check to make sure all your keys function. HINT: to save time label only the keys you use most, or learn to touch type :)

    It is a PS/2 keyboard. But do not try to make a rollerup keyboard out of it. IT WILL FAIL.

    can this be done with a ps/2 keyboard???
    actually i thought about this some time ago.. searched it on the net but could not find this..

    YES YOU CAN! I looked it up and found a schematic! However, its quite complicated.... The 6 pins on the ps/2 each have different purposes as you may know. 4 of them are exactly like the usb. So basically, this is the usb ====.
    under the first "=" that is connector/line 4. the second = is 3 and so on. on the ps/2, the plastic should be on the top. the whole entire left side is going to be used.the very top one is going to 3 on usb, the middle to 4, and the bottom to 1. on the right side, the middle is going to 2. The final connects(soldering) is gonna be fun XD GOod luck!

    Yap it also works.
    It's not about the Plug. It's just about the membrane.
    PS/2 and USB are the same (most of the time)


    Does anyone know if a dogy keyboard short circuits whether It will ruin a laptop/computer or not?

    I won't save it, keyboards cost like $15 these days, and a used one might be even less...

    what if you put a thin platic or silicone coating on this?

    copper? what about aluminium? tho if you do use copper u could always use 2p coins. (if in uk that is)

    Uhh, the newer 2p coins are copper plated steel... However, the older ones should be almost pure copper. You can test the difference by using a magnet.

    Sure! I'll use them if you can make them into sheets for me! I'll just bite the bullet and get some.

    thats 15$ more than you need to spend if you happen to have a keyboard laying around... its also cooler if you said you built it yourself and it works! thats my opinion anyhow
