This is awesome. I'm glad we have have insurance in case no one fills the void of HTC leaving. You can argue that Valve is, but given the massive back orders of the Index and their discontinuing of their controller and streaming box; I'm not totally confident. Now we just need controllers and maybe even base stations.

> fills the void of HTC leaving Huh? I'm out of the loop here. HTC is still selling the Vive Cosmos. What are you referring to?

HTC is going commercial only. From what I’ve seen with other Chinese companies going that route, it makes it either harder or near impossible to buy a single headset when a company takes this route

Great brand name. Awesome write up. "We made Relativty in my bedroom with a soldering iron and a 3D printer and we expect you to do the same: build it yourself." Soldering SMD components sounds daunting, so kudos to you for this. Not sure why the pedantics about 2K and the price in these comments...

Also, it can be quite pleasant. After a while it almost feels like drawing pixel art.

Jees, pls dont. MP should not be used for display resolutions. It's 1440x1440 or 1440p 1:1 But yes definitely not 2K.

I think it's a good idea to use megapixels for resolutions. 720p - almost 1MP, 1080p - 2MP, WQHD - about 3.7MP, my monitor (advertised as "4K") - more than 8MP Also we should use area instead of diagonal measurement to convey the size of a screen.

It's not. You give number of pixels not resolution. Resolution gives number of pixels and aspect ratio the total number does not. array[3840][2160] is clearly not the same as array[4M] Also your assumption of 4K is wrong. Its 4K not 4M it means 4000 and it means approximately number of vertical pixels. 4K UHD or just UHD however means exactly 3840 x 2160 thats whats written on the box of your monitor. People usually think of that if they say 4K.

Hopefully the design won't kill users on launch day.

It's fine - people will be still perfectly willing to continue using it after it does that. ;-) (Plot of later part of Sword Art Online - really.)

The second generation of gear claims to have limiters to prevent nerve damage. Kinda like cars installing seat belts and air-bags.

As someone who has worked in an electronics lab and done lots of soldering, I can say your setup makes a huge difference. A great setup will make soldering SMD components a breeze, but a bad setup will make it very frustrating. Practice obviously helps but a nice soldering station with some kind of magnification will close the gap a whole lot faster.

Using a proper microscope for soldering was definitely one of the most useful things I learned as a high schooler interning in an electronics lab.

I am still surprised that this is not more common. Even a biology-grade binocular microscope for 100$-ish makes a huge difference.
