Ohm is where the heart is. This cheerful electrical engineer mug takes the unit every electrical student learns first and turns it into the cosiest house on the street.
The roof is shaped like the omega symbol, the porch light is a smiling bulb, a tiny striped resistor has taken up residence on the front step, and a happy battery is watering the garden. It is soft, sweet and very nerdy, all at once.
An electrical engineer mug with a homely pun
Most electrical engineering jokes need a diagram and a patient audience. This one doesn’t. “Ohm Sweet Ohm” makes sense to anyone who has heard of Ohm’s law, and makes the electrical engineer in the room very happy indeed.
It is a warmer kind of engineering humour than the usual circuit gags. Where other designs are all wires and schematics, this electrical engineer mug is all rounded shapes, pastel colours and little faces with rosy cheeks.
Kawaii style, technical heart
We drew it in a kawaii style because the contrast is the fun part. Resistance, current and voltage are serious business, but here they live together in a tiny cottage with a flower garden. Even the resistor has proper colour bands, for those who like to check.
The palette is butter yellow, sky blue and cream with crisp dark outlines, so every character stays clear on the white ceramic. The lettering is a chunky dark navy that you can read from across the room.
- Cute pastel house with an omega roof, a resistor, a light bulb and a battery
- “Ohm Sweet Ohm” in bold rounded navy lettering

- Goes in the dishwasher and the microwave
- Printed in Australia and shipped from our studio
Who will love it
It is a natural pick as an electrical engineer gift, and suits electronics engineers, electricians, physics teachers and anyone studying circuits. Because it is gentle rather than snarky, it also works well for people who like their mugs cute first and clever second.
The house theme makes it a clever housewarming gift for an engineer moving into their first place, and it suits a birthday, a graduation or a “congratulations on passing that exam” just as well.
A pun with real physics behind it
The ohm is the unit of electrical resistance, named after the German physicist Georg Ohm. His law ties voltage, current and resistance together in one tidy relationship, and it is usually the very first formula an electrical student commits to memory.
The omega symbol on the roof is the same one you will find printed on multimeters and scribbled across circuit diagrams everywhere. Giving it a chimney and a front door felt like the natural next step.
The supporting cast all have a job to do. The battery supplies the power, the resistor sets the current and the light bulb is the load, so in its own small way the whole household is a working circuit. Engineers who notice that tend to enjoy the design even more, and the ones who don’t are still charmed by the little faces.
Everyday quality
Underneath the cuteness is a sturdy, practical mug. It holds 11oz, which works out to roughly 325mL, and the comfortable handle makes it easy to carry from the kettle to the workbench.
Each mug is printed in Australia with a durable finish that keeps the pastel colours looking fresh through countless washes. It is fine in the dishwasher and fine in the microwave, which is more than can be said for most electronics.
