Electric Travel Mug | Winter 2018
My colleague and I built an electric travel mug in my Engineering Physics II course that could heat or cool a beverage to a specified temperature. A Peltier module, coupled with a custom H-bridge circuit, allowed for the heating and cooling effect to take place. We programmed the mug using Arduino and powered it using a laptop AC/DC power brick. I modeled the tumbler in SketchUp CAD and used woodworking, in addition to hand and power tools to fabricate the assemble.
After the semester, my colleague and I continued to develop the mug making it more compact using a custom PCB, lithium-ion batteries, and a 3D printed body. The design below is similar to what we did in class, but with the batties at the bottom taking the fan’s place and the now passively cooled heat sink in the middle container.
Below is a different concept we came up with where theirs two heat sinks: one on the bottom, whose fins protrude next to the battery pack’s sides. Another up top that extrudes into the container housing the liquid beverage.
