Below it is, one of the most interesting expose considering that the Hackaday Reward event–[Eric Strebel] uses the pulp mold he designed and built over the three previous videos In instance you missed our insurance coverage thus far, [Eric] laid out to develop an environmentally friendly cordless battery charger that’s implied to be non reusable after 6 months to a year of usage, and also looks excellent doing it.
[Eric] begun by reducing up a great deal of cardboard and also coagulating it in a new Oster blender or food processor that truthfully seems rather sturdy. Gelatinating contains mixing the cardboard little bits with water till a slushy chili-like uniformity is gotten to. That blender or food processor lasted every one of 20 mins prior to damaging, so [Eric] quickly changed it with a Ninja, which was way even more as much as the difficulty of cardboard.
To do the real molding, [Eric] combined his mushy chili with ~ 30 L of water in a bathtub huge sufficient to suit the lengthy brass mold and mildew. He dipped the mold and mildew to collect a layer of pulp and also drew it, and after that pushed the cordless battery charger in position to develop a pocket for it in the last, dried out item which he later on changed with an acrylic disk of the very same size. [Eric] mentions that a component similar to this would possibly dry out within 10 mins in a commercial setup. Despite the fact that he established it in addition to a food dehydrator, it still took 4-5 hrs to completely dry. Soup’s on after the break.
This isn’t [Eric]’s initial cordless battery charger. A couple of years back, he prototyped a pivoting variation in urethane foam that does picture or landscape.
