This looks like you may not get the values unless you buy the PCB If Im correct, you get access to the build docs after the fact. Just a heads up and I very well could be wrong.

Ah, from the site:
Order the Tweed Stack pcb for $14 plus postage.
Complete instructions are provided with purchase.
To the original poster, why not try this project:
