Week3

July 4th - 8th

July 4th

  • Finished my abstract for Leadership Alliance National Symposium
  • Looked into information about sound recorder and its components
    • Microphone: inputs analogue voice pattern
    • Circuit: converts analogue to digital
    • Speaker: outputs analogue voice pattern transmitted from the Serial DAC

July 5th

  • Looked further into information about sound recorder (reference)
    • Push-button and LED light
      • takes analogue voice as an input
      • notifies that it’s recording with the red light
    • ADC (Analogue to Digital Converter)
      • converts the analog voice pattern to digital (12-bit)
      • uses DPCM (Differential Pulse Code Modulation) to compress the digital sample (6 bits) sends the signal to MCU
    • SPI (Serial Peripheral Interface) flash memory
      • stores voice data
      • bigger the memory is, longer it can record
      • has to be more than 720kB to record for 2 minutes (8kHz sampling rate)
    • Serial DAC (Digital to Analogue Converter)
      • translates the digital format to the original analogue voice sends data to the speaker

July 6th

  • step by step instruction on Smooth-on products
    • Mix Ecoflex 00-35
    • Apply Ecoflex as the first layer
    • Wait for 4 minutes
    • Repeat 3rd and 4th step for 4 more times
    • Wet Gypsona plaster bandages with warm water
    • Apply the bandages on the ecoflex as a supporting shell
    • Demold
    • Mix Smooth-Cast 325
    • Pours Smooth-Cast 325 into the mold
    • Demold
  • compared characteristics of different products
    • How To Make a Silicone Mold of a Hand - Ecoflex® 00-35 - Versatile
      • Easy to use
      • Soft, strong, stretchy
      • Skin safe
      • 5min cure time
    • Lifecasting Tutorial: How To Make a Silicone Mold of a Kid’s Face with Body Double
      • Skin safe
      • Apply directly to the face
      • Quick cure time
      • Odorless - Lifecasting Tutorial: Making a Mold of Your Face with Reinforced Alginate - skin safe
      • needs trimming after demolding

July 7th

  • looked into exhibition design to increase the awareness on chronic pain
    • display methods - put on the wall
      • hung from the ceiling
      • put on the table
    • medium - panels
      • wooden boards
      • cutting sheet
      • acrylic
      • silicone
    • navigations - state the research purpose and touch on chronic pain and PCR
      • encourage the visitors to interact with therapeutic tangibles and listen to the voice of the patients recorded inside the tangibles

July 8th

  • had a meeting with the project members and shared my findings
