Overheating Protection for Smartphone

thingiverse

For longer bike rides, I always set up my warbiking equipment on the bike beforehand. The Kismet server runs smoothly on a RasPi3, and I use a smartphone for navigation and as a user-friendly interface for the RasPi3. Through USB tethering, the smartphone stays constantly charged while also communicating with the RasPi3. However, this has become more of an issue on warm days because the smartphone is stuck in a weatherproof holder that doesn't provide sufficient cooling. With my new gadget, I'm hopeful that the smartphone will no longer display battery overheating messages. Recently, I put my device to the test and was pleased with its effectiveness. Although the phone did shut down due to overheating during a half-hour break, this happened while we were in the shade. The bike, however, was left baking in the sun without any airflow. In the future, I'll likely need to disconnect the tethering cable when taking breaks.
