  • Very cool, even if I have no chance of finding the time & patience to replicate a project like this! I wonder if an RGB light source would improve the brightness & reduce LCD thermal issues, as it would focus all of the power on the wavelengths that will pass through the LCD rather than be absorbed by it? You might find a 200w RGB LED doesn't increase the LCD temperature as much as a 100w white LED, though of course you'd need to boost the cooling of the LED. On the LED cooling, generally heat pipes tend to work better with gravity assisting them and the thermal load being at the bottom, so moving to a water cooling system may give big improvements if that's an issue. Awesome work. Love your videos!

  • Maybe water cooling the screen by making the water pass between the screen and a 300W LED with a reflector would make it more silent and brighter..

    • I can't really think of any special way to do it tbh... there are switches that have an RGB LED integrated into them, and you can just plop them into a PCB that is compatible with them and call it a day Most keyboards use the clear/translucent housing switches with SMD LEDs on the boards (usually ws2812b or sk6812)

  • I don't see the point of expending a lot of time and energy building an admittedly impressive, but very cumbersome and large overhead projector from scratch, when the same thing could be made much more easily, cheaply, possibly better, and certainly more convenient by being much smaller, all by simply modifying a cheap old overhead projector with an appropriate LED light source, something I'm currently doing and hoping to do a video on. If anyone can tell me that I've missed something and therefore gotten it all wrong then please do let me know, I'd rather be proven wrong than remain ignorant! :)

    MadScientist512MadScientist5128 أيام قبل
  • I've seen many DIY projector builds where the LCD is in between the two Fresnel lenses, so that the light rays go straight through the panel... This is the first time I've seen it done this way with the LCD after the to Fresnel lenses. Is there any benefit to either way? My thought was that with the LCD in between the Fresnel lenses, the light will pass through the polarizing layer "easier" making the image brighter? Any thoughts on this?

  • Higher wattage LED wouldn't that big of a deal. Either of custom water loop or an AIO water cooler running low RPM high static pressure fans. Might even be good for what you built here. Of course you now have to deal with a radiator at minimum, pump/res/rad at maximum. Crazy build, I LOVE it! I might actually build one of these....and I sent this vid to someone I know that wants a 4k projection SimPit for computer gaming. Not sure the details for translating to a computer output, but this person would be the one to bridge the gaps.
