USF-NREC-Project-1-Jacobs-ladder

Metrology Engineer Jay Bieber at the University of South Florida-NREC (Nanotechnology Research & Education Center) assigned project #1 Jacobs ladder

Prototype 1- Functionality

• 2 pieces of 10'" (1/2 a cm) copper wire, oil igniter (6Kv; 100 mA power supply), a power cord, and a switch.

• Used pliers to turn copper wire around positive and negative terminal of the oil igniter cut tip of power cord and peeled back rubber protective coating,

• used wire stripper to strip positive & negative wires spliced power cord wires to positive and negative wires of oil igniter plugged in device to power strip.

• listened for buzzing noise. unplugged from the power strip. adjusted copper wires 1 centimeter at base to 2 centimeters at top of ladder.

• added a switch;

• unspliced power cord wires from positive and negative wires of power supply;

• Splice positive and negative wires to positive & negative wires of switch;

• spliced positive and negative wires at other side of switch to positive and negative wires of terminal;

• plugged power cord into power strip hopefully with the switch in the closed position.

• Flipped switch to open position, observed space between copper wires for ionized air/plasma between copper wires.

• Observed density differential caused by the heat of the plasma;

• creating an upward movement of the plasma between the copper wires until reaching the apex or top of the ladder.

• Then the dissolution of the plasma at the top of the device and the formation of a new plasma at the bottom of the copper wires where the copper wires are closest.

Prototype 2 - Copper Wire Protection.

• Used brackets to fasten 2 plywood boards together at a 90-degree angle to protect individuals from the ionized air/plasma between the copper wires;

• Fastened power supply to the bottom board.

Prototype 3 - Plexi-glass safety cover

• Unfastened power supply from plyboard,

• un-spliced power cord, switch, and power supply wires;

• Used a personal cell phone stand as a holder for the power supply;

• Used Dremel tool to saw and cut beams & boards out of cell phone stand to fit power supply into cleared out cell phone stand box;

• fastened oil igniter power supply to cell Phone stand box;

• fitted switch into back of cell phone stand horizontally.

• Plugged power cord in and tested device.

• Observered successful Ionization of air/plasma between copper wires.

Prototype - 4 Worked with machine shop for final adjustments to Jacobs ladder for NREC demonstrations

• From an oil igniter, power cord , Cell phone stand and Plexi-glass;

• worked with machine shop staff cell phone stand to protect users from ionized air/plasma generated from the 6000v 100mA power supply;

• machine shop staff assisted with professional measurements;

• drilling holes for fastening screws;

• added top for extra safety

• cut spacings for cell phone holder to allow for the wood box to flex allowing plexiglass to fit securely into cell phone stand box.
