you want instructions for the boost controller, or the boost controller itself? I could make you a boost controller if you wanted, I stored away a few springs and ball bearings when I made mine and I already have the tools (my instructions required a really tiny drill bit and an odd sized tap). Considering the time I'd have to put into it, i'd charge 10 bucks for parts and 15 for labor (I'd have to drive around everywhere to get the stuff I don't have).

here are the instructions, it's not difficult to make one. Hardest part is finding all the stuff in homedepot and ace, that was the biggest time-sink of the project.
