I played a bit more this afternoon and quickly ran into hurdles. The circuit I'm reproducing is this one:

1. The design that uses a TI op-amp, the TLV272. There's nothing special about it I need other than rail-to-rail, but that's the exact part I use. How to I get it into Eagle?
2. The circuit I'm working on uses a CD4017 counter clocked by a 556 timer. I hate reinventing the wheel so I'm hoping someone already has this fleshed out, and maybe you can share your file with me?
3. Choices! There are so many resistors and capacitors! I'm trying to choose "standard" parts but it's daunting.
4. There's probably a bunch of questions I should ask that I don't even know about yet.
