  1. Can we interface a pi with a DMD or any other processor manually ? Sorry for the n00b question .

  2. could you try to use this as a low cost adaptive optics to cancel out atmospheric distortion?

  3. Twilight Sparkle always has been big on education…

  4. Wow, thank you! I love your little gadget there. I am a laser optical engineer where did you acquire that DLP chip and driver board I have been looking for such a streamline style for prototyping.

  5. Brony detected. Cutie mark at 3:18.

  6. So how much would a single unit like you have cost?

  7. Sarah Cartwright says:

    Could we have a video where the image on the chip changes throughout?

  8. Lol. Oh. Nevermind. I see

  9. I'm struggling to find information on running one of these as a spectrometer. Any idead?

  10. hi 😀 where did you got this development kit from :D?

  11. Originally all DMD mirrors were developed and patented by Texas Instruments. This was actually classified technology and only available to the US military. TI is still the only manufacturer of these devices which are fabricated using MEMS technology. Every DMD projector manufacturer in the world licenses this technology from TI, buys the DMD device and chip set from TI. Chip requires a 6Gb/second data stream to project a full color moving image with the DMD. Filter wheels in projectors typically spin at 6,000 RPM and are made of 4 glass segments.

  12. DMD device leaks very, very little light and has a better contrast ratio and brightness levels than LCD projectors have. When any of the micro-mirrors are in the off state, the light from these mirrors hits the wall of the optics. White segment is a very small piece of filter wheel. I know something about these projectors, as I have modified them extensively for vision research. Projector light source passes through the spinning color wheel, then on through optics and a small homogenizer which creates a highly uniform light source. A polished glass block with an angled side creates a beam splitter. Design of the beam splitter is different for each manufacturer, and is designed for a particular angle defined by each manufacturer. This is how all DMD projectors are illuminated.
