I've tried to use microcontroller yesterday with object detection and sticky pistons. It awesome things to make interactive defence from griefers.
Also i've built power plant with solar- and hydroturbine which switches automatically from one power source to secondary if first inoperative. Thanks for microcontroller developing! I really like it. :-)
Just let's clear, please, how possible to craft batteries, buttons and levers? That's 'hack' to use it in creature mode, would be much better perform anything in survival mode manually.
UPD: I've found this on your site. Thanks!
Also there is an idea to make a coal power plant. Could you please tell if possible to include something looks as "coal furnance turbine" to mesecons mode?
