Nice to meets y'all :)

Amazingly nothing has broken yet.  Trackpoint action is .. perfect.  Scared to do the keymat+buttons...

Btw in case anyone is wondering why the topic has so many views it reached the first page of Hacker News a short while ago.

Is there any DIY way to wire-up the trackpoint buttons to the Lenovo kyemat controller without having to stuff the entire keymat into the housing under my new keyboard?

You can not solder wires onto the matrix sheet made by PET (in general). Solder wire onto copper tape with conductive adhesive and paste it on the matrix line.

How do I expose the trace?  Can i buy something that will dissolve the pet?
