Overview of Status of Analysis, Design, Fabrication, Tests, etc.
3D printed parts complete
Final assembly started
Calibrate and test sensors in the final assembly
Accomplishments from Previous Week
Completed handle construction and verified USB charging, LED indicator lights, and On/Off Switch working (Chris/Reuben)
Analog PCB tested, many issues found, most significant was ground plane not being continuous enough and causing noise, enough noise in system compared to breadboard to warrant developing and ordering a version two PCB (Chris)
v2 Analog PCB developed, ordered, and received, with continuous single ground plane, bypass capacitance at each IC, room for RC low pass filtering, and every IC on the top of the board (in report for design considerations: 4 layer board instead of 2 layer) (Chris)
Final electronic components ordered, including 0.1% resistors, various capacitors, op-amps (Chris)
Teensy memory optimization code developed for larger buffer size before needing to write to external serial flash memory (Chris)
Handed off acrylic with sensor layout to Chris for testing and final assembly (Kaitlynn)
Finished second draft of webpage (Kaitlynn)
Successfully 3d printed and post-processed all final design components and delivered them to be assembled (Michelle)
Wrote Matlab code that successfully reads all data from Arduino serial monitor (Michelle)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Use National Instruments DAQ in ARMOR lab to gather data from all 16 sensors while miniature DAQ is being assembled (Chris)
Assemble v2 Analog PCB, and test (5/27/2020) Tests include ADC accuracy, true sampling rate, battery life, (Chris)
Assemble Digital PCB, and verify continuity checks (5/27/2020) (Chris)
Assemble complete DAQ connecting analog and digital PCBs and test (Chris)
Complete full running code for 16 sensor tests (5/27/2020) and final product function. Includes MUX, PGA, flash memory, accelerometer, speedy analog to digital conversion, RF transciever (Chris/Michelle)
Calibrate force sensor in final assembly (Kaitlynn)
Obtain data from all 16 sensors for location detection (Kaitlynn)
Finish Matlab code and Arduino code (Michelle)
Finish assembling receiver enclosure (Michelle)

Risks and Areas of Concern
v2 Analog PCB still needs to be tested to see if it works, if the PCB doesn't work we will have to demonstrate functionality on a breadboard
