How did you make the keypad and hook it up? I cant tell from the pictures, you cant see the backside of the buttons or anything....
It is a membrane keypad, approx 3mm thick, with the ribbon connector passed through a slot underneath it,
It is stuck to the enclosure using contact adhesive. The new key designations are printed onto self adhesive gloss inkjet paper and stuck over the originals

I got the pad from here

I am curious about the custom fascia. I have looked at these pads for another project I am working on but wanted something besides the standard 0-9 A,B,C,D etc. Is it robust enough for long term use or will the ink eventually wear off the paper?

Hi,
It is an Simple 5 x 5 (To save Pins on the Arduino ) Array
And the Switches are "Tactile" Switches i used www.conrad.at/ce/de/product/701749/TE-Co...r-NA/SHOP_AREA_17384

They work fine and so i can have 25 Keys so 16 might also be possible if you think of Space

I am fighting right now woth the atc (basically with the axis screen the macros work ) and if that is done i finnish the pendant
I want then also be able to control the tools with it

The printed overlay is not very robust and certainly not oil or water proof. It has fared quite well during testing but I may have to experiment with laminating to try to get an overlay that lasts.

A colour laser printed one would probably be a bit more resilient, I just used what I had to hand.

If you come up with a robust solution to the overlay issue I would be interested in what you discover.

You can get laser-printable plastic film (sold as waterproof paper) which might work well.
I bought a few sheets from eBay a while ago (it's rather expensive by the ream)

I am going to print mine on some of that glossy printer paper made for photos.

ArcEye do you still have the keypad graphic you made and if so can you post it?
