NEWS – If it’s raining, you need an umbrella to stay dry, right? Not according to maker Ivan Miranda. He 3D printed a motorized hat with an internal propeller that uses a curtain of air to keep the rain off. Ivan does a fabulous job of walking through the engineering process, explaining how he designed his gadget and iteratively improved it until it worked (mostly). It’s an 11-minute video on YouTube, and well worth your time.
Have any ideas for an even better solution?
