HAM-gadget (4) – keyboard added

After a lot of fiddling, trial and errors, I finally got the matrix keyboard to work. Also, as the project has passed the prototype stage, I threw together everything on a PCB in preparation for mounting it in a casing.

Note to self:

next time first cut the PCB to size before starting to solder…


The keyboard – for now – does three functions:

  • A – switch the back light of the displays on / off
  • B – toggle between UTC and local time
  • C – toggle between summer and winter time (DST)

Building it up
