My final project will be a key finder. I sometimes have the bad habit to lose my keys and when I need them, I'm always in a hurry to go to school or so. So it might be interesting to have a little base where there is an on- or off- button and when I need my keys and I can't find them, I let the little machine work and my keys, or the second part, starts playing a song. That's all quite similar to what the old versions could do, but it would be nice if, when I find my keys back, I need to connect them to each other so that the song stops playing.
My final project will be a laptop table. The table will be personalized like the ones you buy in the store but with LED who are showing what the temperature of your laptop is. Red for 'shut it down, I'm melting!', orange for 'It's getting hot in here....', green for 'It's a normal temperature', and blue for cold. The other part of the idea is to have a heat sensor in the table, so that the ventilation only starts working when it has to, making it energy saving. The energy will come, just like a normal laptop cooler, from the laptop itself through a usb connection.
