This DIY Electronic Meat Thermometer project will not only have you end up with a cooking thermometer in the end bit you will also learn some signal processing techniques.

"To passionate chefs, cooking is an art. Knowing exactly when a cut of meat is cooked to perfection requires knowing your meat and your grill. But with a little bit of technology, we can build a digital meat thermometer, and use digital signal processing techniques to get a much faster response. This video explains how we can use the predictably slow heat transfer inside the temperature probe to mathematically model the sensor, and ultimately get a much faster response, with a little bit microcontroller computing power!"
