Ghostbusters "Functional" P.K.E Meter

Author: Ant3869

Description

This project is a functional replica of the P.K.E. Meter from the movie Ghostbusters. It not only mimics the iconic design but also serves as a real Electromagnetic Field (EMF) detector.

Features

• Functioning EMF detection.
• Ability to increase/decrease sensitivity/range using the 4 Direct Contact Touch Switches.
• Wings that raise or lower reflecting detection: Higher the reading, higher the raise, and vice versa.
• 7 LEDs on each wing blink in sequence, same as in the film Ghostbusters.
• LEDs speed increase and decrease reflecting detection: Higher the reading, faster the speed, and vice versa.
• 3 unique SFX while detecting (low, medium, and high readings).

Components

• Raspberry Pi Pico with rp2040 (using Adafruit CircuitPython 8.2.9)
• LSM9DS1 D0F 3-axis Accel/Mag/Gyro
• DFPlayer Mini
• 5V 2A Recharge/Boost Converter Power Module
• SURPASS 9g S0009M Servo Metal Gear Motor
• iPhone 5 Loudspeaker
• 33 LEDs (7 on each 'wing', 14 on display screen, and 5 indicators on front panel)
• 16mm Variable Resistor Potentiometer
• 4 Direct Contact Touch Switches
• 3.7v Lithium Rechargeable Battery
