Assessment and Redesign of Mister Craig Hewitt Chaz Hogancamp
Humidification Air intake and output controlled by internal fan Measured using hygrometers and psychrometers
Results of humidity levels Extremely high humidity levels promote bacteria and mold growth Extremely low humidity levels damage vocal cords and sinuses – Makes body more vulnerable to respiratory illness
Reason for mister Biological needs for humid environment – Applications to vocalists in dry air Prevention of ailments caused by dry air Comfort
Progress Assessment of mister performance Contact with Jim Campbell of Clean Air Solutions Created ideas for improvement Focused project goals Began idea implementation
What to do Narrow output from 3” to near ½” Reduce drop size and flow Make tubing inconspicuous and aesthetically pleasing
How to do it Step output down to proper diameter – Dump valve – Feedback loop – Modify circuit board or fan
Problems with plan Backup through fan opening Damaging circuit board Flow through small hose diameter
How to fix problems Replace fan Modify circuit board Seal fan casing Protect circuit board
Other potential uses Hospital room humidity regulation – Burn victim wards – Post pharynx surgery – Others possible through collaboration with Dr. Ed Stone
