This black t-shirt features a clever engineering joke. It shows an electrical circuit with an op-amp wired for negative feedback, paired with the phrase "I ONLY GIVE NEGATIVE FEEDBACK." The circuit diagram includes labeled components such as resistors R1 and R2, and voltage inputs/outputs. The design is printed in a combination of white, blue, and red, making it a standout piece for anyone in the electrical engineering field. It is a fun and geeky way to express your personality and interests. Perfect for wearing to classes, labs, or casual meetups with fellow engineers.
