Home Theater Automatic Cooling – Hardware

Furniture manufacturer IKEA hardly makes any TV tables, capable of accommodating large audio-video equipment for home theater systems. On top of that the few available models haven’t been designed with cooling in mind so they have no opening on the back to let the hot air out. This might easily result in overheating of expensive equipment. I decided to solve this issue with my home theater system by designing automatic cooling device. It has two zones of operation for which temperature limits can be set separately. It uses two digital temperature sensors and two PWM controller cooling fans.

This first part of the project will be about the hardware I chose and the PCB design.
