A few ideas and questions from where I'm at the T3 level (Tier 3 Rocket done, mining Pluto with an Ender Quarry, but still gearing up for a NuclearCraft Fusion Reactor.)
-The special "celebrity shout out" elements used to make the Venus Crystals (which are in turn needed to start the Stargate questline) mainly revolve around combinations of 99 which is Einsteinium, the core element you get from Ender Pearls. With that in mind, I used a Soul Vial on an Enderman from a spawn egg I got as a quest reward, used that to change the broken spawner I received as a reward for finishing a quest tree and turned it into an Enderman spawner, but that in an EnderIO Powered Spawner with a Dual Layer Capacitor, put it in a room with Diamond and Gold Spikes on the far wall, Fans blowing into the wall, a Vacuum Hopper in the middle of the wall of spikes to collect the items (with Item Conduit running those items out of the room to a Sorting Chest to go into Sorting Barrels, one each for Ender Pearls, Enderman Heads, and Unknown Dimlets), and for good measure a Black Hole Hopper just above the Vacuum Hopper with a Diamond Spike on the wall side of it to really suck the Endermen into the spikes (and because with a 4 block radius room around the Powered Spawner the fans don't quiet reach to the wall of spikes from the far side of the room.) I upgraded the barrels to hold tons of stuff so I can let the Ender Pearls pile up
-Cursed Earth (made in this pack with dirt and a Nether Star, one piece is all you need to get started as it spreads to dirt) in a kill room with Fans blowing into a wall of Diamond and/or Gold Spikes with a Vacuum Hopper and Black Hole Hopper set up is great for pulling in resources. As an added bonus, put OpenBlocks Tanks down into the ground a few layers deep under the kill area, put the XP Grates on the top so the XP falls in, and then I have a bunch of Liquid XP - I have started putting some Ender Fluid Conduit in at the bottom of that big connected mass of Tanks and sucking some of that Liquid XP out into Drums, and a Bedrockium Drum would be a great option to really store a bunch. Use that with an Auto-Enchanter or the XP Rod from EnderIO to do it manually by giving yourself the levels you want then doing your enchanting.
-Experimenting in a test world to find a way to regulate the temperature (and thus efficiency) of a NuclearCraft Fusion Reactor, I found that they cool off really fast so I don't need to turn it off for very long. Best way I've found so far is to have a redstone torch tower under the middle of the bottom of the Fusion Reactor that has the top redstone torch off when no signal is applied to the bottom part, run a redstone dot into the bottom torch, then run an RFTools Counter into that and an Extral Utilities Redstone Clock behind that. That way you can set the Counter to how many seconds you want it to wait between redstone pulses. In my preliminary testing, that pulse is enough to drop the temperature in a reactor by 50+ MK so I was trying Counter values of around 180 to 200 and it was working decently well, but it needs some tweaking to fine tune it. Still, best way I've found so far that is fairly compact and thus easy to set up.
-As part of that early testing with NuclearCraft Fusion Reactors, I found that a 4 reactor block Reactor fueled by dual H (the most common thing from running empty cells through an Electrolyser) will get up to just under 16000 rf/tick (so presumably it is just under 4000 rf/tick per reactor block.) This is better than the Advanced Generator I had powering my base but far less powerful than a T/D reaction. That said, though, it is a great way to use up all that H that piles up while running empty cells through the Electrolyser to get the T and D.
-I seem to be having a problem that I saw someone else post about but never saw an answer, it's with NuclearCraft, I can't place the Fusion Reactor block in the spot I made for it in my base. The Reactor block is a 3x3 and I carved out a 5x5x5 area but I can't place it in the middle, tried digging it out to a 7x7x7 and still no. Saw a suggestion to place blocks in the area I want to put it and break them to clear out any strange air blocks but I tried that and still can't place my Reactor block. Any other ideas?
-I have a tree farm ->< Chemical Decomposers -> Chemical Synthesizer -> EnderIO Tank -> Gas Generator (multiblock from Advanced Generators) set up for Propane as my power supply for an Ender Quarry on Pluto but it was really tricky to get set to run consistently because the Synthesizer would clock up with either all Carbon or all Hydrogen and finally the best I found was to put 2 speed upgrades in the EnderIO Item Conduit pulling from a barrel of Carbon and 7 upgrades on the Item Conduit from the Hydrogen barrel (since the goal is C3H8.) I wish that the Chemical Synthesizer could save the last item in a stack in its internal buffer/inventory so that it couldn't ever run out of room for a given input. Anyone found any way to do something like that?
