People have been battling rain for so long as we’ve been round, and someway the umbrella is the best choice we’ve give you for conserving (largely) dry. There needs to be a greater answer, which Ivan Miranda has doubtlessly created by throwing more technology on the drawback.
Sure, umbrellas are low cost and collapse in order that they’re straightforward to hold, however they’re additionally fragile and vulnerable to falling aside when confronted with the slightest breeze. And whereas they’re good for conserving the rain off your head, all that water dripping off the sting of the umbrella’s cover often finally ends up elsewhere in your physique. Umbrellas are actually nothing greater than an over-engineered palm leaf, and for a species that’s efficiently despatched people to the moon and robots to different planets, we’ve seemingly actually given up on bettering how we keep dry within the rain.
Not all of us, although. Ivan Miranda is a proficient maker who shares their creations—which embody all the pieces from a 3D-printed tank they will truly climb inside and drive, to an all-terrain skateboard—on their YouTube channel. For his or her upgraded umbrella, Miranda skips the collapsible cover thought altogether and as an alternative focuses on making a wearable system that manifests a disc of high-speed air over their head that deflects raindrops as they fall.
Watching their total artistic course of is as entertaining as the ultimate product. Their first makes an attempt concerned 3D-printing an impeller powered by an electrical motor used for RC planes that will push air outwards and away from their head when the setup was mounted to a helmet. Nevertheless, 3D printing is an imperfect course of, leading to unbalanced impellers that vibrated so violently it truly affected Miranda’s imaginative and prescient whereas the system was strapped to his head.
The eventual answer was to commerce the 3D-printed impeller for a pre-built (and completely balanced) ducted fan meeting, which is typically used to create RC planes with high-power jet engines. Air is sucked in by the ducted fan’s opening atop their head and directed down and outwards by a skinny 360-degree exhaust slit. The highly effective blast from the ducted fan does precisely what it was designed to do, making a curtain of air throughout Miranda that deflects falling water away (a backyard hose was used for testing) however the answer does include some trade-offs. Not solely will everybody inside a 10-foot radius of Miranda really feel the exhaust and be pelted with deflected rain, however the turbine engine is extremely loud when operating at sufficient pace to maintain the rain away. You’d get to the place you have been going dry, however as an alternative of coping with a moist umbrella whenever you acquired there, you’d be coping with ringing in your ears and potential listening to loss.
