I'm not really sure what you want the circuit to do?

Are you looking to drive the LED's with the 555? I know they can source up to 200mA, so it seems like that would not be enough.

You guys doing this bike stuff need to figure out how to power your LED's off of your pedaling. Then these would be cool projects.

I was thinking about making a series of posts each constituting a lesson or two on common circuits and techniques, eventually culminating in combining them into something cool. I had three different things in mind:

DIY switching power supply, which would cover the following:
Comparators and hysteresis
Relaxation oscillators
Voltage controlled PWM
Switching supply theory
Voltage references
Error amplification
Closed feedback loops

DIY DC motor speed controller:
Pretty much the same as above, except replace Switching supply theory with H-bridge theory

DIY linear regulators:
Zener diodes
Transistor lesson
Voltage references
Error amplifiers
Closed feedback

Reply if you're interested in this. I'd rather not start on such an endeavor unless there is some demand.

This would be cool. I'd really like to get some practical circuit knowledge.

I have The Art Of Electronics, and every time I try to read it, I feel swamped by all the information. This is doubly bad since I am about to graduate with my BS in EE and CPE!

This is the most confusing thing about electronics. There's often JUST THE RIGHT part for a given application. But hell if I know what it is, what it's called, or even necessarily what to look for.

Seriously, it seems like there are billions of IC's, how are you supposed to know what to look for beyond obvious stuff like op amps and regulators?

Is that the sort of stuff you learn in a control theory class? I've been considering taking one for work ever since I started having to do things like implement PID control loops in software. I also found out that my work will reimburse enough tuition to completely cover full time graduate studies, so I am considering complementing my BSEng in Computer Engineering with an master's in EE (I already have most of the foundation classes, it would mostly be just electives).

You wouldn't really get this in a control class. That would mostly cover compensator design for either analog or digital systems, depending on the context of the course.

I just wanted to say that this series you're posting about making a switching power supply is really great. I've been looking for a good summer project and this will likely be it.
