i. Concept- Is the project creative, original, functional, and pushing boundaries? Does the project effectively address the selected challenge?
WILDCARD - The world needs this device, I have never seen one , but without a doubt Covid-19 and other diseases transfer by touch on surfaces we come in contact with. This device solves this issue on every credit card machine using it.
ii. Design- Is there a depth of design detail available (like a system design, CAD models, project test methods, etc.)? Is there base-level planning for the functionality (e.g., functional block diagram, list of specifications and descriptions of how they will be met, etc.)? How user-friendly is the design?
YES! I have pictures and screen shots of the whole process. If I make it to the finals I will post the file for printing as well as a stl.
iii. Production- Is the project realistically reproducible (taking into consideration necessary materials, skills, and production processes)? Are the manufacturing processes detailed? Are those processes realistic for scalability?
YES, it can be printed, but the parts can be split into two halves and screw holes so this can be cast from a mold. It realistically could be a product that every business could install
iv. Benchmark- How well is the project impact and viability demonstrated? Are estimated costs realistic? How well does the project improve upon other currently available solutions?
The parts are minimal, an AC adapter, DC to DC converter to get the correct voltage, a 470um capacitor, UVC 3.5 watt bulb and plastic material for the body
v. Communication- How thoroughly have the Final Round requirements been completed? How well documented is the project? How “open” is the design?
Introducing the Fire Fly UVC Light Credit Card Terminal Sanitizer
It is currently our goal to provide real world solutions built into products we can get into individuals hands.
In my daily supply runs I realized on of the most utilized surfaces that nearly everyone in a store touches is the credit card terminal, it may be as simple as agreeing to the amount charged or entering your pin. In either of these cases these pads could be touch dozens or even hundreds of times a day. With the upcoming opening of states businesses, microbial control of contagions is a paramount issue that we are addressing.
We are currently on our 4th design revision of a add on type of device that sanitizes the Keypad and Touch Screen of every Credit Card Terminal between customers. Really if you think about the solution and climate of business today this is a non negotiable consumer protection solution. The current revision houses a single Star Lighting Industries 3.5 watt self ballasting UVC Quartz bulb with NO ozone production. The eye shield is angled as such that 97 percent of the light only hits the surface of the terminal. The matt black surface prevents the majority of any UV being reflected back and a simple spray on matt coating further supports this before installation of the light. The Bulb is easy to unscrew to show any customer there are no hidden electronics or cameras to attempt stealing their pin information in the event a customer is concerned with the new appearance of credit card machine glow sanitizer. The power wire is ran to a completely separate psu box that brings 110v down to usable 14-16 volts for the UVC emitter.
Fourth Version update-
The newest version is a one piece 6 hour print at .1mm in black PLA. Custom supports are created that can be pulled with pliers as one piece that also is removable from the threads the tub screws into. There is a strain relief on the far left that the power wire is fed through and secured in place with heat shrink tubing.
