Keycaps were installed from my mechanical keyboard so they would have appropriate labels. Blank keycaps were installed around the periphery where they could have any function without an incorrect label.
Programming was done to make all the keys type their respective letter or modifier keys, like shift, Alt, GUI, or Ctrl. GUI is usuall the Windows start key. Since only basic programming was done, only a single letter and a single modifier could be pressed at a single time.
Research into PJRC's keyboard library revealed how easy it was to make the keys behave like keys so that six letters and three modifiers could be pressed at a time, just like any USB keyboard.
After learning a lot with the second version of the PCBs, the third versions arrived. IO expander ICs and resistors were soldered. Soldering the ICs was trciky because I didn't have solder paste handy so it was done with fine flux-in-core solder, a reflow hot-air solder station, a fine-tip iron and a steady hand. Under a magnifying glass, the solder joints looked acceptable.
The rest of the weekly summaries have been arranged by date.
