In a MC video I saw a node, which *ate* a hole into stone...now I've done this:

Contents:
Tunnel bomb: Use a torch to detonate them... go 3-4 steps back, else it will damage you! It only digs cobble and other easy breakable stone-like nodes.
Bridge builder: Put a non-cobble stack into the slot and set how wide it should build, power it by punching with a torch. You can not destroy nodes with items inside.
Autominer: Is maybe a bit confusing, it breaks blocks, but just blocks which you put inside. This can be used for farming saplings or getting clay lumps from clay.
Breaknode, Polished cobble: Breaknodes are thought to construct buildings with it, they are oddly breakable by hand. Polished cobble needs 9 cobble to craft. Should look alot better than the default cobble. Polished cobble gives 8 cobble back on crafting.
Grinder: Requires bitchange (or a modification in the files) to invest money in grinding. Currently it only grinds default ores... extendable.
Depends: default unified_inventory? pipeworks? bitchange?
