My answer is to stay curious and do projects on your time while you can. Even reading about other projects help. This is what helped me persevere through school, because seriously, the subject is very dry in academia. Worse yet, a past internship and my current job (recent college grad here in EE), a lot of it is just documentation and testing, very little design work.
My advice, keep on doing projects and learning the electronics you love to do. For those of you pursuing a degree in it, you might be stuck with office politics and project boredom. Don't let this get you down, keep doing what you love on your spare time and you will remain happy in the field of electronics. And most importantly, you'll learn more.

Not sure if this will help anyone but I had to make a blog about something so I made one on how to make an electronic thermometer. It uses a thermistor and explains some basics of it:
Hope this helps!

Just buy a PICAXE and use the free downloads at parallax.com for examples and guides. The syntax is similar. PICAXE manual is very good and does a great job at explaining the syntax with a quick example. I went from STAMP(self taught) to PICAXE(self taught) to 68000(school, assembly programming) to Arduino(school). I am planning to learn PIC next using assembly and C. But in my opinion, the PICAXE is best thus far. If you need negative numbers and bunch of libraries, go to Arduino, other than that, grab PICAXE. Just stay away from STAMPs, they are overpriced.

Question concerning power.
I know some people talk of cascading many of these things but when you start doing large chains, shouldn't current consumption be a concern? For example, lets say you cascade so many of these, say about 7, and each register collectively "uses" 160mA (20mA per channel - assume the register circuitry used to operate itself is 0A). Wouldn't the register breakout board closest to the power supply have the most "electrical stress". In other words, wouldn't the power supply pin headers closest to the power supply in my example (+5V and GND) have 7 x 160mA = 1120mA = 1.12A? And wouldn't this go beyond the typical current rating of a pin header (typically 1A)?
Anyone see where I am coming from or am I dead wrong?

Is there anyway you guys could make a schematic symbol and PCB footprint for the eagle library?
