1) clear two big spaces, one to do the actual work, the other to lay out all your components (using the sticky bubble wrap is great for this so they don't roll around
2) read through the crack manual, lay out all the components in a logical order, cut/strip/tin wires ahead of time if you want to (lots of prep time, but makes life easier)
3) read through the speedball manual, lay stuff out, etc. you can actually populate the boards as a separate project so feel free
3b) note the four resistors which you'll be replacing in the crack, and remove or mark them from step 2
3c) note the capacitors which will be bent/moved and mark them as well
4) start all the hardware assembly for the Crack, stop before any soldering stuff
5) go back to your speedball stuff and attach the mounting hardware there
6) lunch
7) proceed with crack assembly, omit the four resistors, and when you get to the caps look at the orientation in the speedball manual
8) recreational beverage
9) keep building
10) register for the forums at bottlehead for the inevitable troubleshooting
11) keep building
12) sleep?
13) build, install speedball components, check all the thingies
14) music?
