I'm currently working on a config for adding all the EMC values myself. I have added some things that will be very bad for a public server (i allowed ore transmutation, for instance) and it is not a complete list, but it is a lot of things that people have been begging for (gears and solar arrays (and the things to make them) for instance), so: go through and change what you want, values were rounded up or down depending on my personal balance (.25 extra emc doesnt matter when you can make machines that can double your emc every 5 seconds)
for tekkit: install the bukkit port of customEMC on your server: http://www.mcportcentral.co.za/index.php?topic=3491.0
(client-side prediction may mess up, so it may look like you dont put it into slots, and the tooltip wont say an emc, but the item will be there server-side, and the glitched "duplicated" stack will disappear if they try to pick it up, so it's just very glitchy if the clients don't also add the custom emc mod)
then inside the config folder, put this customemc.cfg: https://www.dropbox.com/s/88mlnigqeyucqwx/CustomEMC.cfg
this is a link to my server's customemc config. go ahead and request any emc values you want added, and I'll try to add them. as for panels: f- you. 27,000 blocks? nope, i'm not doing that mod.
the clients will also need this config if they want the prediction to work properly (stop condensers from flashing, false duplication, shift-click won't work, etc)
PS: this config does include all the dusts, some of the machines, all the IC solar arrays (and the items to craft them) it doesn't have the macerators and such, but it does have the circuts and machine blocks
PPS: i swear a lot while coding, and there are some purposeful mis-spellings and inside jokes (blue sh- or le pee= lapis lazuli, yeller, etc...)
