I can't seem to get the redstone interface to work.

They don't emit a redstone signal no matter what I try, even when using the images on the wiki as a reference. Am I doing something wrong or are they just broken for 1.8.9?

I'm using version 3.5.7.

Hmm works fine for me on latest forge. Do you have any other mods installed?

Nope, I only have Random Things installed.

I'm currently running on version 11.15.0.1694 of forge. I'll update to the latest version and try again.

EDIT: Works on 1697 but not 1694. Weird! Sorry.
