This was a small project to learn eagle. I've never used any eda software before, so this seemingly simple project took a while. But I learned some basic EE principles, circuit design, and board layout, so it was definitely worth it! I also designed it to be single layer and not have a ground plane so that I could try to manufacture it at home with a 3d printer pen plotter and some etchant, the reprap way. But that isn't the main goal of the project, and I'm pretty happy with just learning the basics of eagle, so what I have now is good enough.

The physical thing I wanted to design is a little beeper. It's meant to be a tiny thing you can place somewhere to annoy someone (that's why it says 'screw you' on it). Don't ask why I chose something that annoying to design; I don't even know. It's a simple circuit, and the parts aren't expensive.
