Regarding power conversion, they go both ways. King Lemming was very careful when he specified RF to pick a unit size that could convert easily to both MJ and EU. RF to MJ is 10:1 and RF to EU is 4:1. Both can be done exclusively with integer arithmetic, so power loops shouldn't be an issue. His exact words were:
It's 10:1 with MJ, basically 10 RF per MJ so that I can use integer math on the conversion and have some sort of sub-MJ level energy scaling. This also means it's 4:1 with EU - keeping the integer math once again.
This is why there's no conversion ratios in the config anymore (although, you'll still see the field if you have a config that was originally generated before ET 1.1.6.0).
That all said, for obvious reasons, I still don't know exactly how TE conduits will behave, so I may have to make a few tweaks to the adapters once TE comes out in the even that there are issues. They should work fine with my own Flux Pipes.
Emasher can you post some examples for an automated husher? im fairly confused with how to automate
I don't think screenshots will help out much, but I'll try to explain it as best as I can in words. I'm going to assume you already understand how sockets work in general, and you're using slickwater rather than water.
You'll need a few different sockets doing different things. First of all, the one with the husher itself. It should have the husher module installed on the bottom and on the rest of the faces, you will need a range selector module, a pressurizer module, a fluid input module, an energy input module (or an energy storage upgrade set to input mode using the remote's "white" generic mode), and a machine output module. The fluid input module should be configured to use the same internal tank as the husher. The machine output module should be configured to use an inventory (any one will do really). Finally, the range selector specifies the 'radius' (it operates in a square) of the husher's operation. You use the remote's generic mode to change the range, the setting at the top of the indicator is 1x1 and it increases by one each time. If you don't have a range selector installed, the husher defaults to 3x3. Now, the pressurizer and the energy input module aren't strictly necessary when using slickwater, but they are if you want the husher to be able to mine obsidian or anything under it. Without a pressurizer installed, the husher doesn't actually require any energy to operate, but if it's installed it does require energy for every operation, even if it isn't necessary to mine the block. Because of this, you may want to add the pressurizer later on to clean up any obsidian in the bottom of the hole. Take a look at the wiki for more information on which fluids can mine what and when the pressurizer and energy is really needed. You're going to want slickwater flowing into the fluid input module and the items being mined coming out of the machine output module. Unless you have some other source of sand, mixed dirt, mixed sand, or ground limestone to make slickwater, you're probably going to want to direct at least some of the cobblestone you mine towards a grinder (I'm going to assume you already know how to set one up) and send the resulting sand towards a mixer with an infinite water source (take a look at water intake modules) hooked up to it (again, since the mixer is just a standard ET machine, I'm going to assume you already know how to set one up). The slickwater of course should be directed back to the husher. That should hopefully explain everything. The only thing you really need another mod for at this point is handling the items that come out of the husher. BuildCraft, AE, and Extra Utilities are all good options there.
