schematic for an actuated valve, aka schematic for an actuated valve, actuated, and valve
A piece of printer paper with schematics and figures on it.
It tells you how to make an actuated valve with the following components:
3 - o-rings
1 - short steel pipe
1 - flywheel assembly
1 - servomotor
1 - small spool of q-adhesive micro-slicing fiber
1 - steel pipe cap
1 - circuit board
1 - microprocessor
Making this would take some familiarity with craft.
In the upper right corner is a note: 'First discovered by Dr. Nous.'
It weighs about 100 grams. It is a electromechanical schematic. You have no idea what it might be worth.
