1 Resources Requirements Technical Approach Introduction Audiophiles often prefer the sound of vinyl records when compared with digital storage methods. Vinyl records are also a primary medium of electronic and hip-hop DJs. To achieve the best sound quality, records must be cleaned regularly, a time-consuming process by hand. An ultrasonic cleaning device provides a safe, automated way to clean vinyl records. Current commercial ultrasonic record cleaners are expensive, often costing several thousand dollars. The project goal is to design an effective ultrasonic cleaning device comparable to current models at a fraction of the cost. Abstract Schedule Team Information Client: Ralph E. Patterson, III Faculty Advisors: Ralph E. Patterson, III John Lamont Team Members: Brad Aswegan, CprEAndrew Whitcomb, EE Daniel Wilcox, CprEKen Uhlenkamp, EE Summary Vinyl records, often considered a thing of the past, are considered by many to offer superior audio quality. They have become a rare commodity and those who collect them will go to extreme lengths to care for them. Clean records sound better and last longer, making routine cleaning a necessity for any serious collector. However, vinyl is delicate and care must be taken to prevent damage during cleaning. Ultrasonic cleaning can provide a safe and extremely efficient method of cleaning and can reduce the time spent maintaining a collection. Personnel Effort ( hrs ) Estimated Costs Problem Statement The ultrasonic cleaner must be constructed to be as effective as commercial models while costing only a fraction of the price. The ultrasonic cleaner must be constructed to be as effective as commercial models while costing only a fraction of the price. Approach Statement Available technologies and materials will be tested and selected based on criteria such as effectiveness, durability, and cost. Available technologies and materials will be tested and selected based on criteria such as effectiveness, durability, and cost.Assumptions Used by adults 18 and older Used by adults 18 and older Components cannot be harmful to users Components cannot be harmful to users Cleans 78rpm, 45rpm, and 33rpm records Cleans 78rpm, 45rpm, and 33rpm records All labels are smaller than those of an average 33rpm record All labels are smaller than those of an average 33rpm record Center diameter of each record is the same Center diameter of each record is the sameLimitations Uses 110V outlet indoors Uses 110V outlet indoors Surface defects cannot be removed Surface defects cannot be removed Labels will remain moisture-free Labels will remain moisture-free Records will not be permanently altered Records will not be permanently altered Project will be completed by May 2005 Project will be completed by May 2005 Intended Uses Removing dirt and dust from records Removing dirt and dust from records Adapted for cleaning of other items such as dentures or jewelry Adapted for cleaning of other items such as dentures or jewelry Intended Users May project team May project team Ralph E.
