element14.com has announced the winners of its most recent community challenge, encouraging female engineers to create an electronic project video in the style of the element14 Presents series.

The Grand Prize winner is Surbhika Rastogi from Uttar Pradesh, India, who created an informative video for making an automatic soap/sanitizer dispenser system.

In the video, Rastogi talked through how she used an Arduino UNO, IR sensor and pump made with bottle caps and a motor lifted from an RC car, to make this innovative dispensing system that offers a contact-free way to reduce the spread of germs during the pandemic.

Other winners represent a wide array of experience, skillsets and geographies, ranging from women with PhDs and Masters Degrees to those who are self-taught designers.

Their videos include directions for a light up “cycling shrug” by a costume designer from western Missouri to help cyclists stand out on the road at night,  a robot vacuum created by a college student in Sydney, Australia and a smartboard alarm created by a master’s student in northern Italy that signals when food is about to expire.
