Making a camera was way harder than I thought. Here's what I learned: If you want smart phone level camera, you can't just buy a smartphone camera component That's because cameras talk to a special chip (ISP) that does all kinds of magic There's special image software too, and you can't do it yourself, so it's gonna cost you $100-250k for that software that does tuning, HDR, MFNR, etc. Takes months to implement properly Then it's even worse if you want to livestream. Since you can't do the processing after the fact, you've gotta make all that special software run realtime on a resource constrained processor You also gotta realize our hands and heads aren't stable at all. The video is shaky until you do electronic image stabilization (EIS) If you don't do every single one of these right, then you'll have potato-quality video After all this work, we've now got something really good, and I'm amped to ship Mentra Live smart glasses because it's a smart phone quality camera that sees what you see, live streams anywhere, and has an open-source SDK you can build apps with.

Making smart glasses frames was way harder than I thought. Here's what I learned: Materials matter. You can't use normal plastic, because it has to be light and safe to touch your face So we chose TR90 plastic that's made for eyewear Fake gray-market TR90 plastic is common in China. You gotta go to the source and make sure your TR90 is legit Glue is so important. If you put too much glue it will give issues, and add weight. Too little glue, won't stick. That's why it's better for a robot to do it (VIDEO) If the glue doesn't match the material perfectly, then it won't stick. So we tried like 4 glues to get the best one for our smart glasses You design the frame in 3D and then make a tool. A tool is just a metal mold that is shaped like the glasses. You put a bunch of melted plastic (TR90) in the tool, let it cool, and out pops the glasses frame. Do that 10,000 times Tooling leaves seams in the frame, so we figured out where to put the seam so it doesn't cut into your ear when you wear it Obviously this all must be super lightweight because the electronics are heavy The camera needs a certain perspective, so the glasses frame angles the camera down to capture hands in videos Throughout the design process, you can't sacrifice style And now our Mentra Live frames are born

"You can't move the means of production, but you can move the memes of production." Shenzhen has the world's best hardware building infrastructure. But it's also rapidly brain-draining the people (memes) all over the world to go build there. And now the US is banning immigrants like me while China opens its arms. China is rapidly changing policies to make visas, travel, and business easier. At the same time, every smart immigrant to the US is shaking at the knees that they'll get banned from re-entry, denied a visa, etc. Talent is everything and nations will rise and fall based on their ability to attract the world's best. If half the US discourse nowadays is about how scared they are of China, why are they building a wall that keeps out all the cracked people? Isn't is obvious now all those cracked people will go find some other high tech, giant economy to go contribute to instead?
