right here it is, the most interesting expose because the Hackaday prize ceremony — [Eric Strebel] utilizes the pulp mold he developed as well as developed over the three previous videos. In situation you missed our protection so far, [Eric] set out to style an environmentally friendly wireless charger that’s implied to be disposable after six months to a year of use, as well as looks great doing it.
[Eric] started by cutting up a great deal of cardboard as well as pulping it in a brand-new Oster blender that honestly looks to be quite heavy duty. Pulping consists of blending the cardboard bits with water up until a soupy chili-like consistency is reached. That blender lasted all of 20 minutes before breaking, so [Eric] quickly replaced it with a Ninja, which was method much more as much as the difficulty of cardboard.
To do the actual molding, [Eric] mixed his pulpy chili with ~30 L of water in a tub huge sufficient to fit the long brass mold. He dipped the mold to gather a layer of pulp as well as pulled it, as well as then pressed the wireless charger in location to produce a pocket for it in the final, dried piece which he later replaced with an acrylic disk of the exact same diameter. [Eric] explains that a part such as this would most likely dry within ten minutes in an industrial setting. even though he set it on top of a food dehydrator, it still took 4-5 hours to dry. Soup’s on after the break.
This isn’t [Eric]’s very first wireless charger. A few years ago, he prototyped a swiveling version in urethane foam that does portrait or landscape.
