Dangerous Prototypes has a wonderful program where they give away blank PCBs of their prototypes. I may or may not have spent eight hours last Sunday hitting refresh on their website while watching TV, trying to finally win a free PCB. I built a Logic Shrimp, which is a four channel logic analyzer, which is super useful for debugging digital circuits. I had a little trouble finding some of the parts, so here is the complete BOM for the Logic Shrimp on Digikey:

And notice that many of these parts, particularly the passives, are very useful to have in stock, so where the list asks for eight 0.1μF caps, I would order 100. Hope this list is helpful.
