Tweaks

This mod also adds stats to all the different gears, All the gears have a maximum amount of power they can transfer and a power multiplier.
Handy tooltips are added to each gear to show that it can be used in a gearbox and to tell the player what the stats are, if it has any.

If a gear is spinning too fast, it will emit smoke particles to indicate that it's losing power.

Lastly, a bunch of gears from other mods can also be used in gearboxes with this mod, and if a gear from a mod isn't supported by default, you can just add it to the config file.

Other features

This mod also adds some other things to integrate other mods with mystical mechanics.

A redstone dynamo is added to convert mechanical power into energy which can be used with any mod that supports forge energy like thermal expansion or immersive engineering.

If botania is installed, a flower is added that turns mana into mechanical power and an automated version of the manatide bellows is added that runs on mechanical power.

If thaumcraft is installed, a research tab will be added for mystical mechanics and a vis motor and essentia motor are added.

Config

Every gear can be individually disabled in the config file and all the stats can be changed too. All the tweaks, mod compatibility and other features can also be disabled if it suits you better.
