"Its great to see this technology become automated. The first time I had heard of using a hot knife on foam was from this French/Japanese artist known as Mizui. He used car batteries and manually fed wire through blocks of foam to create studies for larger works in stone. He was looking for the same smooth undulations seen in the process above. But 40 years ago. https://yasuomizui.com/en/the-wall-of-hope-english-ok/"
"I think that the Audi version was a hinged flap that pivoted down and behind the mirror, bridging the gap between the visors. It was out of the way when not in use. It didn't totally block out everything, but it was good enough. "
"Coffee freak here, recently bought the larger canister and finding it to be just about perfect. There is an audible hiss from the valve that verifies the trick being done here, which is nice. The handle is robust, nicely sized, and dummy proof, even for pre-coffee fumbling. "
"Porcelain is Ceramic by definition, just a clay variety of denser and finer particles, fired at a higher temperature. But by also glazing these pieces, it introduces other ingredients into the overall makeup. "
"After viewing the video on the kickstarter site, I am convinced that this machine has a number of disadvantages. A single boiler espresso system separates the brew and steam functions, resulting in 2 main issues. One is having to wait for the boiler to heat to the steam temperature level, and two, having to then cool the boiler in order to create another shot. As for the choice of materials, that is more of an opinionated decision. There is a solid reason many espresso machines use stainless steel, its because it cleans easily and remains clean for years. Concrete is porous, would liquid coffee and grounds not create a problem here? I have also just now read that coffee stains corian, requiring a hassle for remaining clean. How are these materials honest? I have cut and pasted the text from the FAQ section of the kickstarter site, that answers? a question concerning cleaning: "Please note that concrete is a raw material and should not be saturated completely. As a raw material it will change color over time and develop a patina, which is what gives it the unique character. The brass on the Corian model will also need some care and attention."That, right there, is the honesty I was looking for.The video captures the creation of a shot of espresso in 11 seconds. That beverage is therefore junk. I realize that it is just for video demonstration, but if the design research and development was 4 years in the making, more effort could have been spent in the video to convince me that these folks take coffee seriously.There are retail units available that function identically to this machine, for less. There are also espresso machines available for the same price, that offer more functionality, like a hot water outlet, a cup heating surface, and a pressure gauge. https://www.seattlecoffeegear.com/espresso-machines/semi-automatics?dir=asc&order=price"
"Facts to keep in mind here: There's a roughly 20% weight loss in the coffee roasting process from its green state. Roasted coffee is best when let rest for 24-48 hours after roasting. From there, if sealed, that can last for maybe 2 weeks without grinding. Final roast temperatures range from 410-455F, which highlights the fire risk of any device. The process produces a significant amount of smoke and aroma throughout its temperature rise, from sticky sweet grassy, to peanuts, to a final coffee finish. Doing this un-vented and indoors is probably not ideal. Lastly, control of the heat vs air varies widely across the roast time spectrum, and differs by bean. Using one push button roast recipe, and then controlling the duration is just not going to work for a range of beans. Their profile aims for 400f, which is not ideal. "
"Free cad software, or even the googler, would make that math easier. However, the real world difference here is the wall thickness of the material, and the fact that the smaller neck cylinder wasn't calculated into the equation. And, there is usually a pushed in area on most manufactured 'bottle' containers bottom surfaces, to avoid wobble when sat on a somewhat flat surface. Sure, its close, in volume but, when you are titling your video with the word precisely in it, well, you are asking for comments. And, I didn't have the disc sander in my dorm to make that bevel edge."
