well sure, for aesthetics, but i thought the rule on kicksharter was that you were supposed to have a functional prototype a solid piece of phone-shaped nylon with a photoshopped stream of coffee coming out of it is...like...second year design school at best

You were supposed to have physical prototypes, to prove you could make something at all. Don't matter how crappy it is. Because people would just post 3d renders and get funding for physical product.

I don't think it even has a bladder in it for the coffee. I think it's a 3d-printed block of plastic with another 3d-printed block of plastic that slides into a hole and they're pretending that they have something that works. I know this because industrial design is literally my field of professional expertise. like -- they have some process photos halfway down the page that are showing gloved hands doing something mysterious and technical, but they're just cleaning resin off a stereolithographically-printed model. plastic models, nothing else. the stuff they have would be fine for a conceptual product in a second-year design studio, where the point is to have the student work through a design process and build a representational model to evaluate form and fit and not really delve into engineering questions. i don't know what kickstarter expects i guess but they are nowhere near what even a layman would call a "working prototype" Sagebrush fucked around with this message at 03:27 on May 5, 2017 |

Wrath of the Bitch King posted:seems like an even dumber vehicle for replenishable coffee filters and supplies than the juicero. if you give the description a good look (and I guess have experience dealing with bad machine translations) you can figure out that it isn't even that complex. the cartridge has the already brewed liquid coffee in it, kept fresh by some magic membrane. putting it into the case breaks the membrane and lets you pour it slowly through a tube which is heated by a battery within the case which heats it up to serving temperature. there is zero reason for it to be a phone case or have an app.

6.6Wh is the iphone's internal battery. i didn't realize the case had its own battery as well (yay, now you also need to charge your iphone coffee maker case) and yeah the power draw they suggest is several times what even the most generous figures would safely allow

fishmech posted:You're too focused on what you'd need to make real espresso from real starting points. Yes, and they literally say in the description that it heats 25 g of water from 15 to 60°C. the energy required to do that is determined by physics. Even if we assume the coffee is already at body temperature from being in your pocket, that's still roughly 350 watts required to meet their performance figures. The battery can safely source 60 to 80 watts. You cannot get around this

If they had just said that it takes 60 seconds to "brew" the coffee, they'd have something plausible. I believe you could draw enough power from the battery that size to heat up 25g of water to 60 Celsius in one minute. They'd still have all kinds of efficiency and insulation problems to work around but it wouldn't be literally impossible with contemporary technology.

saying "these numbers are impossible" automatically implies "they must be exaggerating" i know there's a saying that goes "if you can't blind them with your brilliance, then baffle them with your bullshit" and it looks like you've shifted to the latter part of that curve in your old age, fishmech no hard feelings, everyone loses their edge eventually
