Conical Conductor for Electrostatics Subcategory_Brushes Simple-form Boyle's Law apparatus pairing

Simple-form Boyle's Law apparatus pairing a graduated plastic syringe on a wooden block with a weighted piston

100 by 100mm friction slider

providing a quick swap-in reference for general-purpose AC-circuit and timing-experiment work
