01/31/11 - Meeting @ 3:00 pm with Sophie Rand.

• Introduction of project and other areas that needed more thought and improvement
• Discussed possible games that could be used for trampoline jumping
• Discussed the basic setup of the trampoline and Sophie showed the group a flow chart describing the sequence of jumping actions
• Plan to brainstorm game ideas and research different types of sensors for next meeting -SR

02/03/11 - Meeting 4:00 pm to 6:00 pm with Sophie Rand.

• Since our last meeting, Uyen found a simon game for arduino
• Sophie assembled the arduino and it seems to be working
• Ordered sensors which Denitza and Mike found
• We ordered a distance sensor and materials to assemble a touch sensor -SR

02/06/11

• Group meeting
• Film and upload introductory Video

02/07/11

• Denitza, Mike and Janet researched stepper motors
• Created the a flowchart for a disc burnisher - a device which uses a stepper motor

02/14/11 - Meeting With Sophie Rand 3-4, 5-6

• We received the materials which we ordered during the last meeting
• Sophie explained the soldering process
• Janet and Mike soldered wires to both distance sensors
• We plan on meeting tomorrow to continue work with the sensors.

02/14/11

• Janet and Mike worked on creating the Quality Function Deployment chart.

02/15/11

• 12-1 in dorms
• Group met and finalized the QFD chart
• Uploaded chart to wiki
• Updated wiki
• Next meeting with Sophie is Thursday to work on constructing the touch sensors

02/17/11

• 4-5 in Lab with Sophie
• got together materials and tried to make pressure sensor
• still need Fusible Interfacing and Popper/snap buttons from fabric store

03/16/11

• 4-8 in dorms (Uyen)
• started brainstorming game ideas
• started working with pressure sensors
• started working with LEDs and breadboard
• started tinkering with Arduino, trying to figure stuff out
• created program for pressure sensor and divided the input into steps, with each step corresponding to a different LED color
• concept can be applied to soft, medium, and hard jumps on the trampoline, and if two are set up, the players can attempt to jump with equal efforts exerted

03/17/11

• 12:00-4:30pm in M.E. Materials Lab with Sophie
• designed and made a few prototypes of small touch sensor
• tested prototypes with voltmeter and LEDs
• started making larger versions of prototypes that worked best

03/20/11

• 3-6 in dorms because NAB was closed
• Uyen modified arduino programs and constructed circuit for Simon game
• worked on midterm presentation

03/21/11

• 3-6 in M.E. materials lab to continue and finish making sensors

03/27/11

• 6-8 Uyen fixed and finished assembling motor control shield

03/28/11

• 3-5 in M.E. Materials Lab attached sensors to breadboards and battery and test on trampoline with LEDs
• IT WORKS!!

03/29/11

• 10am - 1pm Denitza and Uyen figure out steps for stepper motor
• program arduino to use motor control shield to move stepper motor in designated direction
• connect motor to ports designated on motor control shield and test code

04/18/11

• Meeting with Professor Lima from 3-4pm
• Brainstormed solutions to existing problems
