Junkyard Apprentice

I have to say, I came here and read the comments and started farming minnows and spare parts. I was 100 away from the achievement. I went to Pascal and noticed in his list that I could make over 100 Emergency Powerpacks because they simply cost 5 Energy Cells and I have tons of them in my bank because I hardly ever use them. I have made tons and tons of CRATES which don't count toward the achievement. Parts and CRATES are used in almost everything. I am exalted with Rustbolt and I have unlocked every single schematic on Pascal. This is one of my last achievements. Getting to this point has lead me to have an overstock of these Energy Cells which I just happily burned through (over 500 of them) to get this achievement. XD

I'm surprised no one has mentioned [item=166972] it only takes [item=166970] which you will have in surplus anyway by doing regular activities in Mechagon unlike [item=166846] which you can never get enough of. This is not a farm method though, simply a complementary method to take of fifty or so points of the 250 point achievement by using resources already at your disposal.

S.P.A.R.E Crate does not count towards this.
