This morning I really struggled to get out of bed. Being very tired still, in a nice warm bed while outside it was -7 °C and my room probably wasn’t far off that, it took some convincing that I really did need to go to work. While laying there, between drifting in and out of consciousness, I got to wondering if I could make my room a little warmer without changing the central heating settings or adding another heater. I had the idea that I could set up my computers to respond to temperature.
