Schematic Ideas

[Cogman]

Ok, for this class (its a CompE 150 class, so really not that advanced) I need a simple analog circuit. I need some idea of what to build. It can't use a digital chip, and it has to be able to fit on a 2"x2" board (so it can't have that many parts to it). Think on the level of having a blinking light.

So any schematic ideas would be appreciated. The project is mostly to demonstrate good soldering capabilities.

Just so you know. I am thinking of doing something like this http://www.uoguelph.ca/~antoon/circ/canary.html

How about this?

Make a simple A/D converter out of comparators... add as many as you'd like and hook up LEDs to the outputs. Connect a pot to the input and you have a simple analog (potentiometer divider voltage) to digital (LEDs) converter.

Yea. I'm so making this for my EE306 project.

CMoy headphone amplifier is small and easy to build. Documentation is extensive and it's actually useful when you're done.

What about an oscillator to make some blinking lights?

I would do that, but that was our first lab. My partner and I decided to go with the canary schematic.

Thanks for the suggestions though.
