Overview

No matter how thick the socks and no matter how many foot warmers you stuff into your ski boot, there are some days when the conditions are just too brittle for comfort. We aim to solve this by developing a ski boot heater in which a rechargeable battery pack fitted to the boot powers up two heating pads, one on the top of the foot and the other on the toes, meshed within the boot. And to ensure customization and to combat overheating, there will be a temperature gauge the user may interact with to adjust the temperature to his/her liking. This interface will also be fixed to the boot, and have thickness so that it may double as an encasing for the Arduino, circuits and breadboard. Each heating pad will be linked to a LED button, which lights up when clocked on, and an accompanying dial under each button to allow for the user to manually adjust the warmth of each pad. A row of 4-6 LED's will be located at the top of the interface to illustrate how hot each pad is.

Objectives

  • To create an efficient closed loop system between the battery pack and heat pad that does not lose power[1]
  • To prevent the boot from overheating
  • To ensure that the panel boot warming system is waterproof and unaffected by the elements
  • To create an efficient and elegant user interface that will allow for the wearer to control the temperature of each heating pad.[2]

Challenges

  • Learning how to use Arduino in creating a user interface for temperature control
  • Ensuring the general safety of our design, by eliminating exposed wires and ensuring a limited amount of current is supplied to the heat pads so that they do not overheat
  • Encasing all exposed electrical components to not only make the product look more polished, but more importantly, to ensure the system is waterproof
  • Learning how to 3-D print to create encasings for the interface and any exposed electrical components
  • Creating an effective, closed-loop system
  • Ensuring there is enough voltage in our battery pack to power the heating pad, without compromising comfort of functionality of the ski boot
  • Further down the road, we would like to see if we can add a solar panel component to our system as an additional means of charging the battery. Should we tackle this, figuring out how to attach the solar panel onto the ski in a way that is both strong yet matches the ski’s flexibility will be another challenge.
