Having said all that I now realize you're probably asking about your matrix.
I see two problems where you have the column wire going sideways with the row wires. That isn't going to work.
Left most column on both hands (viewed from the keyboard being the right way up).
yeah i was pretty sure that was going to bite me after i started looking at it and working up my matrix on paper. but i needed to put it out there to the community to be sure. i'll rewire it in my spare time and go from there.
to answer your other question i am using a teency2.0 but i ordered some breadboards to mount the teency to using pins and will be mounting all that under the housing. more pix to come in the build log BCDMK001.
thanks again! i hope this helps someone other than me.
