About this model

This is a vertical seismometer sensor based on the popular TC1 design. Neodymium magnets are suspended inside a coil of magnet wire and generate a voltage signal in the coil when physically disturbed. Instead of winding a custom coil, I used an 8 oz spool of 36 AWG wire with a spool internal diameter of 20mm. Ten 18x2mm magnets are hanging inside the coil, suspended by a Slinky Junior. The spring hangs from a printed cap and hangar at the top of an acrylic tube. At the end of the spring is a ball and socket style assembly to ensure the magnets hang vertically and are not skewed by the attachment angle of the spring spiral. Nylon hex nuts are contained in a printed ring inside the tube, and the coil is held in place with three printed supports centered by three nylon hex bolts. Knobs were p…
