THE PROBLEM

Our touchscreens are disgusting, and researchers are increasingly turning to UV-C light to disinfect them. UV-C is naturally blocked by the ozone layer, but can be artificially created and it is known to be germicidal. How can we create a convenient way for people such as teachers to disinfect many screens at once?

THE SOLUTION

Using hardware store materials (making them easy for anyone to procure) we can create an enclosed system that bathes screens in UV-C light and charges the devices at the same time! All we need is a box, a UV-C bulb, a power strip, and some elbow grease. Watch the video above for all the details, and click these links to buy the materials I used to create my sanitizer/charger:

• Norman Lamps CFL15/UV/MED Germicidal-UV Compact Germicidal Bulb, 15W, 120V

• ABI E26 Light Bulb Socket to 2-Prong US AC Power Cord Adapter with On/Off Switch, 12 FT Cable

• Westek SLC4CG Gray Automatic Photocell Sensor Control

• iClever BoostStrip IC-BS01 Portable Smart Power Strip / USB Charger

• LEDwholesalers UV Protection Adjustable Safety Glasses with Yellow Tint, 7821

• Pendaflex Portable File Box, Black, 11″H x 14″ W x 11-1/8″ D (41742)

Beat the flu with this easy and inexpensive charger and sanitizer!

I also designed this 3D printable iPad stand to sit inside the system. As always, you can download it on Thingiverse or edit it for yourself on OnShape!
