Very cool, and great video.<p>It seems that projector tech (like laser printer tech, and flatbed scanner tech) has been pretty stagnant, the last few years.<p>Every now and then, I look at the latest projectors, to see if there's any justification for me to replace my old (10 years or so) LED projector, and I have not seen anything that has made me want to.
A bit clickbait calling it "infinity contrast" even if it's higher contrast than an LCD, is it still a finite contrast. Probably not higher contrast than modern OLED TVs, but a clever hack with stuff at hand. Just not up to the hype of infinite.
I'm glad he is back to making approachable projects. It was a boon for me during the pandemic. I particularly love the fake windows to light my closet that looks like daylight.
I think it's odd to make a whole video about a DIY rear-projection television without using the phrase 'rear-projection television'. It's novel to bounce it off the ceiling, and it repurposes e-waste so it's a great project.
This is an old concept. There was a research lab in Vancouver circa 2008 who did exactly the same thing (I applied to intern there as an EE student). It was the first HDR video display ever built. They had to also design the encoding format.<p>They never commercialized but they sold their patents to Dolby who turned it in to “Dolby Vision”.
Very cool and a great speaker. Forgive my naivete but would enclosing the back with a short-throw projector reintroduce the LCD light bleed he fought hard to eliminate? I wonder how you would address that. I suspect painting the interior Ventablack wouldn't be enough.
The results he's able to achieve with this are very impressive. I wonder if consumers would accept a TV that isn't paper thin if it had OLED performance at LCD prices.
