PCHIP Keyboard Instructions

Step 1

 

Gather all your parts and tools needed:

Tweezers

Exacto knife with fresh blades

Small files

Acrylic Paint

Rags

Rubbing alcohol

OPTIONAL….but very helpful:

Rotory tool (dremel)

Beer….

STEP 2

 

Remove any clear film from back of buttons with tweezers

STEP 3

 

Remove buttons from tape, place face up on table.

 

STEP 4

Take some acrylic paint. I prefer the thicker artist tube acrylic, but craft paint will work too.
I found using my finger to push the paint into the engraved areas works better then a brush.
After it dries, take a rag dampened with some rubbing alcohol and wipe the buttons down. The idea is to fill the engraving with paint so its flush with the top of the button. Repeat the filling process until satisfied.

STEP 5

“If you received the keyboard faceplate with the black double sided tape already installed
     don’t remove the green backing tape yet, move on to step 6.”

The kit contains a stack (3pcs.) of industrial grade pressure sensitive double sided foam tape, this is the keyboard membrane.

Peel the layers apart, but make sure to keep the green backing attached to each piece.

Line up the tape and place as in the photos above, then carefully trim away the excess. Repeat the process with the second half. If you mess up or tear the tape, no worries, that’s why I included the third strip of tape. After the tape is down, go along and make sure the edges are pressed down completely flat.

DO NOT REMOVE THE GREEN BACKING YET!!!!!

STEP 6

Take your color filled buttons and place them in the correct holes. Use your Pocket kit chip keyboard as a guide. I’ve also found that a tweezers helps immensely when placing them in the correct orientation.  That tape is odd stuff. It’s pressure sensitive. So once you push down hard it’s stuck forever… so get it right the first time.
Seriously take your time with that step.
Do one key at a time
Pinch the button and tape together with your fingers and then repeat for the next button.

STEP 7

This step is critical….this effects how well the button’s action is.
Remove the green backing from the tape
Find the sheet of those little black “nubs”.
Don’t worry about losing some. I purposely added 30 extra just in case.
Now take your tweezers and grab one.
With your other hand “gently” push the button from the front so you can see the imprint from behind. Place that nub standing upright directly in the center of the circle. Push down on the nub with the tweezers to set it in place
Repeat the process for each button, go slow, when you get to the 4 way arrow button you’ll have to use your best judgement to find the right spot to place the 4 nubs.

STEP 8

The bezel is pretty straight forward to modify.
Line up the keyboard so it sits centered on the pocket chip keyboard area.
Push the top of the keyboard up to touch the installed  clear bezel. Now where those two pegs touch the bezel is where you want to remove material.
I take an exacto knife and scribe around the pegs onto the bezel while holding everything in alignment.

Now remove the clear bezel from the chip.
Carefully Remove the material inside your marked lines.
There are many ways to do this, but just remember, that bezel can break easily. So don’t be too aggressive with the removal process.
I like to use a small hand file. A sharp exacto knife will work also. Go slow…I repeat, go slow.
You can always take off more but never add material back. carve it out, test the fit remove more if needed.

After that, clip the silver clasp onto the bottom and enjoy the keyboard!

The buttons will feel a little stiff at first but relax after some use. If your buttons don’t have a mild click feeling to them you may need to adjust the nubs placement underneath.
Please contact me if you have any more questions

Remember
Go slow…
