Phy120B Final Projects Demo
</br>
	2:30pm  Friday 11-Dec-2009
</br>
	2120 Warren Lecture Hall 

<p>
This course involves practicums on data acquisition and
control using microprocessors for the first 5 weeks;
and then students spend the next 5 weeks in teams of ~2
developing and building a project of their choice.
<p>

The theme might be described as "just go for it", with the only
requirement being that the project detect something in the real
world, process the information, and control something in the real
world.  About half the projects use embedded PIC microprocessors;
some use PC-scale computers, some are not computer-based.
