GND Dad Hat - Ground Yourself.

GND Dad Hat — Ground Yourself.

The ground symbol is the quiet workhorse of electrical engineering — three shrinking bars marking the point every voltage in a circuit gets measured against. No ground reference, and every measurement in the circuit is meaningless; nothing "high" or "low" means anything without something to compare it to. It's the least glamorous symbol in the field and also the one nothing works without.

Wear it when you need the reminder more than the joke — the emblem reads as a clean minimal mark to everyone else, and as "go touch the reference point" to the one person in the room who needs to hear it.
