This is a really minor problem but here it is anyway. The current GUI for the electrolyzer doesn't have the input and output box in the right places. The code specifies it for x location while the picture shows them in y location. The easiest way to fix this was just to change the picture. Below is the corrected picture that I created. For those interested you can just put this picture in your IC2sprites folder within the minecraft.jar file now. Just make sure it is named GUIElectrolyzer.png so that it will overwrite the old file.
Thanks so much for this! Much cleaner looking and intuitive!
I couldn't even get my electrolyzer to WORK before this. I could not put the uncharged water cells in either of the left hand boxes, I had dropped them in what seemed to be a space on the right but nothing was happening, even though my MFSU is at 97%. Swapped in your GUI picture and tried to move the cells into the left-side slot, and viola!
You've done noble work here, sir. No one needs to die today, thanks to you.
Thanks for pointing this error out.
Kinda shows up how rate this machine is used at all XD
