Components

Components

1. Camera (with AI Image Recognition)

  • Source: Cameras can be salvaged from old smartphones, tablets, laptops, or even webcams.
    • Smartphones/Tablets: The front or back cameras from older models can be repurposed.
    • Webcams: Common in older laptops and desktop computers, and can be found in second-hand electronics stores or recycling centers.
    • Where to find: E-waste recycling centers, second-hand shops, or your own discarded devices.

2. Optical Sensors (for Light/Color Detection)

  • Source: These can be salvaged from printers, scanners, or barcode readers.
    • Printers/Scanners: Both devices often have optical sensors used to detect paper presence or scan documents.
    • Barcode Readers: Old retail barcode scanners can provide optical sensors that detect reflected light or color.
    • Where to find: Discarded office equipment, e-waste centers, or second-hand office supply stores.

3. Weight Sensors

  • Source: Weight sensors can be salvaged from digital kitchen scales, bathroom scales, or old postal scales.
    • Digital Scales: The load cells inside these devices measure weight and can be repurposed for a sorting system.
    • Where to find: Old household items, online marketplaces for second-hand goods, or recycling centers.

4. Magnetic Sensors

  • Source: Magnetic sensors can be obtained from hard drives, speakers, or metal detectors.
    • Hard Drives: Old hard drives contain neodymium magnets that can detect ferrous metals (iron and steel).
    • Speakers: Speakers have magnets that can be used to sense ferrous metals.
    • Metal Detectors: Some industrial equipment or metal detectors contain advanced magnetic detection systems.
    • Where to find: E-waste centers, second-hand electronics stores, or discarded home electronics.

5. RFID/NFC Sensors

  • Source: RFID and NFC sensors can be salvaged from old smartphones, access control systems, or RFID tag readers.
    • Smartphones: Many modern smartphones have built-in NFC sensors that can be repurposed for reading RFID tags.
    • Access Control Systems: Old building security systems or keycard readers often have RFID sensors.
    • Where to find: E-waste centers, discarded smartphones, or second-hand electronic stores.

6. Microphones

  • Source: Microphones can be salvaged from smartphones, laptops, headsets, or voice recorders.
    • Smartphones/Tablets: The built-in microphones in these devices can be repurposed for voice recognition or communication in your sorting machine.
    • Laptops: Many laptops have integrated microphones for video calls that can be reused.
    • Headsets/Voice Recorders: Wired headsets or old voice recorders often have functional microphones.
    • Where to find: Discarded smartphones, laptops, or headsets from e-waste recycling centers or second-hand electronics stores.

7. Speakers

  • Source: Speakers can be salvaged from laptops, televisions, old radios, or headsets.
    • Laptops/Desktops: Most older laptops and desktops have built-in speakers that can be reused for audio output.
    • Televisions and Radios: Discarded TVs or radios often have small speakers that can be extracted and repurposed.
    • Where to find: E-waste centers, second-hand electronics stores, or from old laptops, TVs, or radios.

8. Display

  • Source: Displays can be repurposed from laptops, tablets, televisions, or old monitors.
    • Laptops/Tablets: The screens from old laptops and tablets can be reused for displaying sorting instructions or eco-points.
    • Televisions/Monitors: Larger displays can be sourced from discarded monitors or older TVs, though space might be a consideration in a smaller machine.
    • Where to find: E-waste centers, second-hand electronics stores, or through discarded laptops, tablets, or TVs.

9. Computer/Motherboard

  • Source: The processing unit (computer/motherboard) can be sourced from old desktops, laptops, single-board computers (like Raspberry Pi), tablets or smartphones.
    • Old Desktops/Laptops: The motherboard or processor unit from an old desktop or laptop can be salvaged to control the sorting machine's sensors and interface.
    • Tablets/smartphones: The motherboard can be salvaged to control the sorting machine's sensors and interface.
    • Raspberry Pi or Similar: If available, a single-board computer like Raspberry Pi could also be used, especially for lightweight computing tasks.
    • Where to find: E-waste centers, second-hand stores, or old discarded computers or laptops.

Summary of Where to Obtain Sensors and Components:

  • Old Smartphones/Tablets: Cameras, RFID/NFC sensors, microphones.
  • Laptops/Desktops: Cameras, microphones, speakers, displays, motherboards/processors.
  • Printers/Scanners: Optical sensors, displays.
  • Digital Scales: Weight sensors.
  • Hard Drives/Speakers: Magnetic sensors (from hard drives), speakers.
  • Metal Detectors/Industrial Equipment: Magnetic sensors.
  • Headsets/Voice Recorders: Microphones, speakers.
  • Televisions/Monitors: Displays, speakers.
  • Single-Board Computers (Raspberry Pi): Can be used as the main computer/motherboard for control.
