I googled and added it up (just out of curiosity) using the BOM, and total cost was ~$88USD (not counting shipping) Also, the OS is FreeRTOS (Open sourced by AWS/Amazon in '17) if anyone is interested

Plus the... holy crap that 3D printer is only $170?

We haven’t solved homelessness, poverty, cancer, or war. We don’t have self-piloted flying cars. But for about $90 in parts, one person can design, manufacture, and build their own bespoke smart watch. Humans have made truly remarkable progress in some very specific ways.

>But for about $90 in parts Oh and I don't know, about $250K worth of professional experience and skills but yeah.. we have.

My ten year old daughter recently built a robot that finds a face and then applies blush. We used an old printer for parts, a blush brush, and an Arduino clone. That's $3 in parts. She also had no prior experience with the Arduino or C, though she knows a bit of Python.

That is the level of technology that we are at today. We are living in the future. And it is a future that Asimov would like.

The “we don’t have flying cars” argument always strikes me as begging for something to complain about. We could easily have flying cars if there was literally one reason to have a flying car. There is not a single reason to have a flying car, so no one has put in the time to make one because no one would buy it because it’s pointless.

Flying cars would be a great solution to congestion . Assuming perfect reliability, reasonably low sound levels, super high efficiency engines, and flying pigs.

Flying cars would move the congestion from the surface roads to the skies. Over your house, over your children's heads.

And those 1000 KG bullets would be, on average, piloted by someone with the skill of the average driver today.

No thank you.

Homeless, poverty, cancer, or war are all people problems, and people are complicated. We do have flying cars but they're not very good at flying or driving.

With credit reports and landlord background checks, I think homelessness will be a rising problem because everything now goes into a database that sticks with you for 7 years.

I have an acquaintance who was evicted (due to property damage caused by her ex boyfriend). She was given a 3 day notice to vacate, and now she has an eviction on her record. The eviction basically means that she cannot rent a property in her own name for the next 7 years, even though she's gainfully employed and can pay rent. After over a month living in a hotel, she finally found an off-lease sublet. But that's only temporary.

Homelessness: unsolvable in a society where it is illegal to force someone to take care of themselves (by being sheltered). The west has decided that individual freedom is worth the cost of some people using it to choose to be homeless. I think this legal framework will make it impossible to solve homelessness. Poverty: It is now known that there is a rising gulf between subjective and objective well being. A majorit…

> Poverty: It is now known that there is a rising gulf between subjective and objective well being. A majority of millionaires do not think they are rich. I think this psychology will make it impossible to solve poverty.

I'd argue (and I'm not a millionaire) that being worth less than 10M isn't really that rich. A long-term pet peeve of me is that most people don't realise how poor they are, if you treat everything as being relative.

For most civilians, access to wealth and being able to access debt (and leverage) is tied to house prices, and a lot of house prices in high-paid areas are beyond the reach of most people. Thus, by extension, access to wealth is not easy for most people.

Trying to have access to wealth AND having at least one stay at home full-time parent? Even harder to achieve in this day and age. People born between the 50s and 80s basically were able to both get on the wealth ladder AND afford for one parent to dedicate themselves full-time to parenting their children.

What does adding "old" do?

You'll get the 'old' design. Check with your "private mode" browser : - https://www.reddit.com/ - https://old.reddit.com/

Interesting those have not only different designs but also different stories for me. I prefer the old one.

I was expecting a brick on wrist, but this surprised me! And the circuit looks simple. I love the charging dock and textual of the watch frame! Screen resolution is a bit low though. I'd join if there's an open source community dedicated to work on this stuff, I think there's a lot of room improve the OS and software. I'm glad to have seen this!

> I was expecting a brick on wrist, but this surprised me!

Agreed, I can't believe how thin and professional it is! This has to be the most mind blowing thing I've seen for a long time. :O

And if you had zero of the tools and equipment beforehand used in the process, what would the additional cost be to just get started?

The case is 3D printed on what appears to be a $160 Monoprice Mini Delta. Soldering was done in a reflow oven, commercial units start at around $200 or you can use a modified toaster oven. This board doesn't look too terrible to do with an iron or hot air gun either. You can get a decent combo hot air/iron station for about $60. You'll want some test equipment, cheap multimeters start at free from harbor freight but…

The aQFN package of the particular microcontroller they use would be impossible to do with a soldering iron. You could do it with hot air though.
