New Textures!
As of the 2.15.0 release for MC 1.16.5, the mod has had a full retexture, thanks to Ridanisaurus:


Documentation
In-game documentation is available, thanks to Patchouli for all versions (thanks Vazkii!) and (on 1.12.2 only) IGW for MC1.12.2 (thanks MineMaarten!). Most video tutorials for the original 1.7.10 version of PneumaticCraft are still largely relevant to modern releases (but remember that modern releases use Oil, and not Plastic Plants, for making plastic).
However, here's a (very) quick summary of what the mod offers:
- PneumaticCraft has its own power system, based on compressed air. It's a little multi-dimensional, in that machines and tools store air by quantity, but many operations depend upon air pressure, which is a function of the machine's volume and the air quantity stored.
- Pressure generation is via several compressors: solid fuel compressors (burn whatever will burn in a vanilla Furnace), liquid fuel compressors (see below), a compressor which uses lightning strikes and FE/EU compressors.
- A Heat mechanic; some machines require heat, some compressors produce heat which needs to be dissipated
- Liquid fuels are refined from oil which the mod adds as worldgen; some of the refined fuels are of very high quality. Fuels from other mods (notably the Thermal suite, EnderIO and Immersive Petroleum) will also work.
- Several crafting mechanisms, all of which can be configured externally via CraftTweaker in 1.12.2, or via datapacks, KubeJS or CraftTweaker in 1.14.4 and later:
- Explosion Crafting - converting items via explosions (with a configurable loss rate)
- Pressure Chamber Crafting - converting one set of items to another set via pressure
- Refining - converting an input fluid to one of more output fluids via heat
- Thermopneumatic Processing - converting a fluid and/or item to another fluid via pressure and/or heat
- Assembly Line - converting items via robotic assembly arms
- Several crafting mechanisms, all of which can be configured externally via CraftTweaker in 1.12.2, or via datapacks, KubeJS or CraftTweaker in 1.14.4 and later:
- A fully-programmable Drone system using a graphical programming language. These Drones can automate pretty much anything.
- Item logistics system, either using pressure tubes or drones
- Base defence systems:
- Hand-held Minigun
- Drones with Miniguns!
- Minigun turrets
- Security Station, allowing full control over who may enter your base
- A full armour suite with many upgradable abilities (including a fun flight mechanic)
- Universal Sensor able to detect pretty much any world condition you can think of and emit redstone based on it
- Vortex Cannon for clearing leaves & grass and flinging entities around
- Gas Lift for pumping fluids
- Upgradeable item and liquid hoppers; can point any directions and with upgrades can run extremely fast
- Elevator system with nameable floors
- Aerial Interface for automated access between your player inventory and your base no matter how far
- ... and much more
