1.18.12 Cutting the PCB connections for a Logic Probe and soldiering a DB9 connector interface.

Today, I started off in the soldiering room to build a DB9 connector interface.

I came back to the class and worked the rest of the time on the Logic Probe.  I never worked with an Exacto knife, so I was very cautious not to injure myself.  I took detail in not cut the desire connections on the PCB.  I used the multimeter (ohmmeter) to test for connectivity.  I worked on it more outside of class and performed more testing.
