I am currently using the Wireless Crafting Terminal mod for AE2 and it can be placed in the head bauble slot. I thought that having my DE capacitor set to charge equipped items and toolbar would recharge this while in the slot but it doesn't. Would be a nice, convenient cross-mod addition.

This has already been done in dev.
New version coming soon(tm)

I guess, but honestly that feels like a waste to me. Baubles are unbelievably powerful.

Whatever you want, I suppose.
