Heres my first all Legit-Semi-Hightech-base in SSP,
http://www.mediafire.com/?d17ajd19dj95tak
I have a Thaumatorium, Diamond factory-(can be adapted to create almost anything), and a EE duplication room
Ive been re-learning EE because i havent played with it since 1.7.3, thats why theres so much EE/Thaumcraft stuff.
Havent played around much with IC2 or BC yet, will do that later =D
Enjoy!
Edit:Im using version 6.0.7 with this map, parts may be incompatible with other versions.
The diamond factory in short- One condenser chest should turn diamonds into obsidian, obsidian should flow into the alchemical chest with overflow going to another condenser chest that turns it into diamond blocks. RP filters take Obsidian out of the alchemical chest and throw it into thaumium crucibles. Crucibles are wired to the Duplicators, and a RP retriever to take the diamonds out of the duplicators and put it back into the 1st condenser to repeat the process. Hope that makes it a bit clearer if your trying to replicate it. Good luck, also good idea with the redstone function on the AND gates to control the combustion engines, going to copy that idea for later use. ;)
