The hardware development community at hackaday.io put together a challenge to build something awesome in less than 1Kb, so we decided to join the fun. Here's our entry.
despite all of your friends who like to say that "heat goes up", heat actual moves according to this equation,
$$ \frac{\partial T}{\partial t} = \alpha \nabla^2 T $$
If you're wondering what on earth that means, you have two options: study differential equations for a few years or watch the colors change on our LED board. This LED board displays our solution to the 2D heat equation, written in less than 1Kb of program space, which we've entered in Hackaday's 1Kb Challenge. If you were to heat up a 14.5x10.9 inch sheet of copper, the heat would move through it exactly as our board displays. The same temperatures would be at the same locations at the same time. Don't believe it? Grab your thermocouple and follow the details over at Hackaday.
