    Really good video, excellent graphics. I have pulled a number of these projectors apart but didnt realise some of the details you explain. Im amazed at the MEMS mirrors and equally the alignment of all the parts in these projectors and yet they are thrown away with no appreciation of the incredible technologies in these devices.

    I enjoyed this video. I was a bit shocked that you said your projector is LCD as it most definitely is not. You have a DLP Pico projector. No DLP controllers would ever be in a LCD projector. But, your video was great with animations and really spot on in many regards. There are also single chip LCD projectors, which are pretty much garbage. Finally, LCoS projectors own the high end of the consumer market space as used by JVC, Sony, and even one from Epson. The ultra high end, as theaters use, is the three chip DLP.
    I’ve moderated Projector Central’s forums for years, feel free to reach out if you want any follow on work or ideas.
    Keep up the great work.

    There is no mention of rainbow effect (RBE) artifact, which all single-DLP projectors produce. Some people never see them; some people see them but are not bothered; some people instantly get sick when they see RBE.

    You should have mentioned the problem that appears with single DLP systems and color wheel or sequential led, which is the "rainbow" effect that bothers many people. While three LCD, LCos systems have the problem of RGB channel alignment.
    And you could already comment that in systems with DLP the micro-mirrors are not only updated sequentially for each color, they are also modulated in pwm to adjust the saturation of each color.

  • @zackphy
    @zackphy 3 года назад +2

    That last one reminds me of CRT tvs, a light beam drawing lines across the screen, or in this case a laser on a wall. If they could ever improve the tech to make full screen images at 60 or even 120hz it could potentially provide the best looking picture ever. Actual bright vivid lasers making up the picture would look phenomenal.

    • @claws61821
      @claws61821 3 года назад

      CRT used to HAVE 120 hz monitors before LCD took off. Even 240 hz and higher LCD and LED monitors today often compare poorly to 60 hz CRT in terms of reproduction quality and overall brightness despite the advances in detail density and fineness.

    It is unlikely that the speaker module has an amplifier inside as mentioned. Besides not being practical from a design standpoint, your speaker only has two wires which are highly likely the two wires to the voice coil. It's also clear from the picture that the speaker module has an active speaker and a passive radiator to extend the bass.
