Small Air-Core Solenoid Subcategory_Kinematics Length-adjustable wooden pendulum simple-machine model

Length-adjustable wooden pendulum simple-machine model with a blue bob sliding along the string and a wooden guide keeping the swing on a consistent path for period-vs-length measurements

the medium-strength option for classroom investigations into magnetic poles and field-line geometry

8mm rod attachment and a centered 50mm aperture together hold a lens square against an optical-bench rail for repeatable refraction

and baskets for scrubbing metal parts in workshop and garage environments

Converts a 3-bit binary input (0V/5V logic) into a 0 to 7V analog output
