Using the Arduino microcontroller I have devised a method of using the voltage produced by a power LED to measure its own temperature to within +- 10 °C without the need for an external temperature sensor e.g. thermocouple, thermistor or digital sensor. In this instructable I explain the details of my idea as well as the code and how to implement this in an existing system. As far as I know I am the first person to implement this idea and I am planning on entering it into the Google Scien...

SolidEnergy Systems' battery (far right) is twice as energy-dense, yet just as safe and long-lasting as the lithium ion batteries used in consumer electronics. The battery uses a lithium metal foil for an anode, which can hold more ions and is several times thinner and lighter than traditional lithium metal, graphite, carbon, or silicon anodes. A novel electrolyte also keeps the battery from heating up and catching fire.
