Self Inflected Problems

During the last session, the crew switching Hamilton reported that 2 of the 4 turnouts were no longer moving when the button was hit.

Of course, it was 1 turnout per crossover, which made it even more inconvenient.

I use tortoise switch machines under the layout to move the points on anything and they are driven by a LCC node. Most of the turnouts are driven from the Nucleo DevKit nodes, which can be configured with different hardware options on port C (the dedicated tortoise port).

After looking at the node for Hamilton, I realized that I had pulled two of the driver ICs out.

Whoops.
