I'm always too hot in my bed, so I set about to create a air-cooling system for my bed. The bed I had designed and built a year earlier, knowing that I might undergo some sort of cooling system renovation, so it was easy to implement the changes. On my night-table, or night-box, I built in a few switches to adjust and control the cooling system. I guess you could say my bed is now a 'smart-bed', as it know also incorporates a temperature sensor so the cooling can automatically adjust.
The 20 super-silent cooling fans pull air from the masthead through the frame over the bottom the mattress and out of the base of the frame. The fans are connected on two power bus's which can be controlled separately.
