Revision as of 19:52, 20 February 2014

Our final presentation in the hackathon: here

LaunchPadSignalGenerator - using the TI Tiva evaluation board (Cortex M4) to generate a signal, how to setup the gcc stack. (didn't try code studio).

Ultrasound sensor physics and construction

Weekathon notes

Notes from the IATI MNC weekathon wearable bladder monitoring device weekathon

  • Project outline:
    • Ultrasound sensor
      • how to build?
      • where to buy a crystal? what size? how does it relate to the driving frequency? receive/
  • Use 6 MHz
  • Get raspberry pi working
  • Get gpio 6 MHz on the pi
  • Opamp @Tami to get to 5V at least from pi using a breadboard / weld stuff
    • 3M from Nachum.
    • TODO 5 V at entrance with op amp
    • TODO 6 MHz, not 3 MHz
  • TODO take with me from the hacker space per what Aba said:
    • soldering station (take mine)
    • make some easy hook wires
    • tomorrow: check that the p6d works
  • TODO can I make an ADC from one of the chips we have?
  • DONE can I make a pulse generator from the EK-TM4C123GXL? yes.
  • DONE can I use the oscilloscope of Guy to record the signal? no.
  • Getting ge p6d probe to work
  • ultrasound general electronics documentation:
  • DONE Meeting with Ronen's coworker at GE
    • Etgar 4 Tirat Hacarmel, 49/45/47; take train at 8:25 from

Prep day notes

  • Bladder monitor
    • sensors, can it work with 40Khz cheap distance sensor?
    • if not, how cheap can we find an imaging (X MHz ?) sensor? interfaces to RPi?
    • build a model, plastic bottles, for development and demo.
    • forced drinking for forced urination (> 300 ml / 15 minutes)
    • ordering of input/output of sensor
      • side by side (like regular distance sensors)
      • one on front, one on back
