Networked sprinkler controller connector clip
My wonderful open-source networked irrigation sprinkler controller betrayed me--the connector to the sprinkler wiring system had pulled loose when someone disturbed the cable, and so for some unknown time it said it was watering my plants, but it wasn't.
I made these clips to hold the connector securely in place.
This fits the original OpenSprinkler and expansion from rayshobby.net, but the new cases currently on offer probably will require some enlarging of the connector opening for these.
