I know this is probably not what your channel fully is about, but did you ever think about building a custom mechanical keyboard from scratch? Without a pcb the soldering can be a mess, but some people managed to create awesome builds! (r/mechanicalkeyboards is quite a rabbit hole and as if recently the hobby has been exploding a bit)

When focusing the collimator lens, you say to get it down to its smallest possible dot. Would it not be better to get it to a dot the size of the LED? I know nothing about physics, so I'm assuming I'm just going to be corrected. Either way I learn something.

They make IR cutoff glass filters. That might solve the LCD panel heating and allow a brighter LED. It just doesn't solve the the noise but your liquid cooling solution in your artificial sunlight video would

Using more powerful LEDS and water or forced air cooling on the display would allow for a much bigger or brighter screen, or more importantly allow the high dynamic range of the screen to be utilised, something this build isn't doing to its detriment.

I get this video is pretty old by now but wouldn't it have been better to make the system have a positive air pressure to avoid dust build up on the lenses and screen. I feel like that dust in the long term would dramatically cut down on the optical quality

You could get the brighter led and liquid cool it.
Jean-Beau Acum 13 Zile
I think the lumens being so low is a huge downside, but there's something that could be interesting that you haven't talked about ; Doesn't the way this projector work mean that there is a very low latency ? i guess it should be tied to the lcd display latency ? Going for 4K wouldn't be worth it for me ; a very good 1080p lcd display (low latency, HDR if possible ?) would be better though

This is brilliant! However, I'm never going to build this! Lol! My skills limit me to just buying a "manufactured" projector. Yeah,it will cost tremendously more money but, it will work regardless of my personal building skills! Lol!! My hats off to you sir!
