Techy Techy Backpacks

# Techy Techy Backpacks

**Six tiers of backpacks and 29 modules that make them do the work for you.**

Carry up to 120 extra slots on your back, wear the backpack in your chest slot, or place it in the world and pipe items in and out. Modules turn a backpack into a portable crafting table, a furnace, a magnet, a trash can, a fluid tank or a jukebox, and they keep working while you play.

Every tier has its own look, from stitched leather to netherite, and every screen matches the backpack it belongs to.

## Backpack tiers

| Tier | Slots | Module slots |
| --- | --- | --- |
| Leather | 27 | 1 |
| Copper | 45 | 2 |
| Iron | 54 | 3 |
| Gold | 81 | 4 |
| Diamond | 108 | 5 |
| Netherite | 120 | 7 |

Upgrade a backpack in a crafting grid with the next tier's material. Everything inside, and every module, stays where it was.

## Modules

Craft modules from a Blank Module and put them in the slots on the right of the backpack screen. Right-click a module in your hand to set its item list (allow or deny, by item or by mod).

| Group | Modules |
| --- | --- |
| Gathering | **Collector** picks up what you walk over. **Attraction** pulls nearby items in. **Disposal** destroys junk. **Filter** decides what may go in. |
| Moving items | **Replenish** refills your inventory. **Transfer** and **Retrieval** fill or empty a chest. **Tool Swap** picks the best tool for the block or mob. |
| Workstations | **Workbench**, **Anvil**, **Smithing** and **Stonecutter** open from a button, themed to the backpack's tier, with JEI's "+" button on the crafting grid. |
| Cooking | **Furnace**, **Smoker** and **Blast** cook with fuel from the backpack. **Compression** turns nuggets into ingots and ingots into blocks. |
| Looking after you | **Nourishment** eats when you're hungry. **Remedy** drinks potions and milk when needed. **Reinforced** makes a dropped backpack safe from fire, explosions and the void. |
| Space | **Capacity** doubles stack size, **Large Capacity** quadruples it, **Reduction** halves it for machines that want small stacks. **Nesting** lets backpacks fit inside, one level deep. |
| Fluid, power, XP | **Tank** holds fluid and **Pump** fills it from the world. **Battery** stores energy and charges items. **Experience** banks your levels. |
| Fun and creative | **Jukebox** plays the music discs inside. **Supply** (creative only) never runs out of listed items. |

- **Placed backpacks** work with hoppers and pipes for items, fluid (with a Tank) and energy (with a Battery). Furnace, Compression and Battery modules keep running while it stands.
- **Hotbar bar**: a small picture of your backpack sits beside the hotbar and shows how full it is, green to orange to red.
- **Backpack Guide**: a 14-page book given on your first join, craftable from a book and leather, and readable on a lectern.
- **Found in the world**: backpacks can turn up in chest loot and on some mobs (both can be turned off in the config).
