by Small, smart home devices can easily upgrade your dorm room when you head back to school. Take, for example, the $35 Amazon Echo Dot smart speaker.
The Echo Dot, which is powered by the Alexa voice-activated digital assistant, does everything the full-size Echo does for half the price: Control other smart home devices like light bulbs, set timers, answer the random questions that keep you up at night. It also includes an aux-out jack for quick, direct connections with external audio setups.
