1) Gunpowder. Now you may be thinking, "Creepers drop the stuff. What's the point?". Well, real gunpowder is a mix of 75% saltpetre, 15% charcoal and 5% sulfur (British mix as of 1879). Instead of risking your life killing creepers, you could mix 4 saltpetre (from ground, unheated nitre ore, most common in desert biomes), 1 glowstone dust and 2 coal dust. This would create a convenient, gun-mod-friendly alternative to organic gunpowder.
2) Scrap Blocks. Lets see...You have gone from wasted items to scrap from the Recycler to scrap boxes. However, your industrial manufactories are continuing to produce more and more waste. What do you do? You make a BLOCK of scrap. That's right, compacting 9 whole scrap boxes worth of material into just 1 cubic metre of stuff! Mega landfill, here I come!
3) E-Meter. You know the EU-Meter, right? The handheld version? Well, to me, it's a pain in the neck to constantly click on the cable to get a constant reading. My solution: a meter to constantly measure the EU going through a wire. Just place the meter wherever you want and run the cable through it, like a BatBox or transformer. The GUI would have a show the EU, voltage and total quantity of EU that has and is going through the wire. Recipe:
