WTM Sense log

Week of 1/30/17

• Finalized our project idea, combining two of our different ideas into one
• Met with our TA, Andrew, for the first time
• Downloaded Fusion360, Autodesk program and began to learn how to use it
• Andrew showed us how to use the 3D printer
• Created our project proposal, budget, and Gantt Chart
• Began to research the products which we will use to construct our speakers

Week of 2/6/17

• Met with our TA, Andrew, to review our project design and proposal.
• Discussed the weaknesses of our proposal and how we could change our project while still including an interesting demo at the end of the semester.
• Opened Arduino and looked at how examples (Blink, DigitalRealSeries, etc) were coded for use.
• Decided to design only one speaker doc for the project using Raspberry Pi.
• Redesigned the purpose and use of our speaker to include:
  • Weather
  • Time
  • Hand sensored volume control
  • Hand sensored pause and play control
• Started to recreate the proposal, which will be finished by Monday

Week of 2/13/17

• Met with Andrew to finalize our project proposal
• Final project idea
  • Speaker doc
    • Plays alarm from iPhone
    • Plays music from iTunes
    • Displays time and weather from internet
    • Leap motion to detect hand motions that will
      • Turn alarm off
      • Pause and play songs
      • Change the volume of a song
• Set up two Raspberry Pis so that Audrey and Savannah can work simultaneously
  • Audrey will work to control the display from the Raspberry Pi connected to internet
  • Savannah will work to control the Leap Motion from the Raspberry Pi
• Ariel has begun working with Fusion 360 to prepare to design the dock
• Savannah has begun researching the functionality of a Leap Motion and the programming language Python to connect the Leap Motion to the Raspberry Pi
• Audrey has begun experimenting with the Raspberry Pi and learning the programming language Python

Week of 2/20/17

• Audrey did tutorials with connecting led's and buttons to the Raspberry Pi, as well as connecting the display to the Raspberry Pi
• Savannah researched connecting Leap motion with the Raspberry Pi, and did tutorials with python
• Ariel continued modeling the dock on Fusion360

Week of 2/27/17

Savannah

• Downloaded leap motion software onto personal laptop to complete physical tutorials with the hardware
• Experimented with python code that can control the leap motion
• In the process of getting leap motion software onto raspberry pi

Audrey

• Began building the circuit to connect the display to the raspberry
  • While waiting for supplies to get here she created a prototype display to use as a dummy to test “hello world” tutorials on the display and raspberry pi
• Found a weather code and clock code that she will combine together and improve upon

Ariel

• Finishing up the 3D model of our dock
  • Made adjustments for the purchased parts to fit properly

Team

• Purchased parts

Week of 3/6/17

Savannah

• Started the week by wiping the raspberry pi SD card to restart downloading the leap motion software onto the pi
• Completed the leap motion tutorials and started writing code in Python
  • The code will be used to read hand gestures by connecting the leap motion with the raspberry pi

Audrey

• Researched codes online to find similar projects
• Creating a code for our project using different elements from a few different online projects to fit our needs

Ariel

• Putting specific minor changes and touches on the dock to create a perfect model
  • Changed the model from a filled box to a hollowed out shell to allow for the purchased parts to fit inside
  • Designed an angled back stop holder for the I-Phone to stand up
  • Made minor other changes and tweaks

Week of 3/20/17

Savannah

• Unfortunately, the Raspberry Pi was not able to meet the minimum system requirements for running the Leap Motion
• I am now using an Ultrasonic Sensor - HC-SR04 to carry out the motion-censored function of our project
  • Connected the sensor to the pi and began working with the code that will be used to carry out the commands between the sensor and the phone

Audrey

• Connected the phone to the speaker and amplifier and was able to play music through the speaker
  • Researching further on volume control using a digital potentiometer through the raspberry pi with the speaker
• Constructed circuit for LCD display and got screen to light up
  • The potentiometer didn't work so was not able to vary the contrast and thus couldn't get text to show up on the screen, so researched more into the problem

Ariel

• Tweaked angled back stop to be more supportive of iPhone
• Designed a port hole for the audio jack to fit into without falling through
• Changed dock design to account for shift to the ultrasonic sensor from leap motion
• Began printing dock
  • Print failed due to a lack of plastic, but will reprint this weekend

Week of 3/27/17

Ariel

• Finished printing dock
  • The first print stopped mid print due to a lack of filament in the printer
  • The second print ran smoothly and was finished Wednesday afternoon
• Started working on the final presentation by creating a poster format and starting to add details and information to help demonstrate and explain our presentation and project ideas

Audrey

• Spent time getting the LED display to work with messages sent to it by the raspberry pi
  • Successfully integrated the two
• Began testing out the different codes she found online for a weather station
  • The one we have decided to follow is RotoTrons International weather clock tutorial, which she was able to correctly implement after changing parts of the code to fit our needs.
    • She is having trouble getting the clock into central time, as it is now only showing the world clock, and is researching how to fix this.

Savannah

• Connected Ultrasonic Sensor - HC-SR04 to Raspberry Pi to read distance of an object placed in front of it
  • Working on code to fulfill the needs of our specific project
