Component Decade Box and Component Kits

[jonwilhelmjr]

I have a few goals in mind. One I would like to experiment with filters on a breadboard. I would like to have a datasheet and spice model for every component. I am willing to swap components as needed.
The plan is to create a signal, calculate the outcome, simulate the outcome, and finally breadboard the outcome.

The second part, I would like to build decade boxes similar to
 IET Resistor Decade box
But I would like to
1. have the experience of building some (it can be rewarding)
2. have datasheets to reference and use spice models
3. see if i could build one for cheaper
The decade boxes can use SMD, i am comfortable.

I am asking for part numbers or part families. what components would be worthy of calibration. Most of all I am looking to fill my component drawers with <1% standard values for bread boarding.
To summarize, What (RLC) part numbers or part families would you buy to one put in your component drawers and two what part numbers or part families would you buy to build decade boxes (RLC).

For the decade resistor box you might take a look at this thread from 2011:

There's also a thread in the forums about a thumbwheel capacitance box project.

But, I doubt you'll be able to make one cheaper than one that just uses jumpers instead of thumbwheels:

Most of all I am looking to fill my component drawers with <1% standard values for bread boarding.

I don't see the point. High-precision parts are very expensive.  Besides, when you breadboard you will introducing a lot of other additional R, L and C into your circuit which will swamp the extra precision.

It's better to get a good multimeter so you can measure the values of the components you have. 1% or even 5% parts should suffice for almost everything you want to do.
