Overview of Status of Analysis, Design, Fabrication, Tests, etc.
New motion sensor (ultrasonic) circuit and testing completed
Circuit for thermistors and halogen bulb completed
Mount for bulb designed
Design for hand-lifting mechanism underway
Accomplishments from Previous Week
Halogen bulb temperature testing has begun
Thermoelectric modules on order and preliminary analysis done
Motion sensor choices finalized
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Experimentally determine temperature and power profiles for halogen bulbs in different locations [Thomas]
Thermoelectric experimentation, halogen mount fabrication/choice, laser research [Inri]
Finish box assembly, housing and hand lifting mechanism [Naif]
Integration of circuitry with all proof-of-concept parts [Jason]
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Temperature measurement of the finger in non-contact tests are difficult to do: Temperature of glass at the time of reaction is fine [Email, April 30]
Temperature of the surface of the glass selected for the experimental method
IR thermocouple is a possibility for non-contact testing [Email, April 30]
This part is being researched
The design is very close, any sort of proof-of-concept is fine [Sponsor consultant meeting, April 26]
Design simplified [stationary halogen bulb selected]
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Sufficient focal heating is not possible with thermoelectrics [In person, April 25 and April 30]
Parts on order, experimentation will be conducted once they arrive
Sapphire should not be used for heating [In person meeting, April 25]
Sapphire is being considered as a lens for a laser (if lasers are used), not the material used for the contact surface
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
None
Risks and Areas of Concern
