This also covers three-tube home models which, while bulky, can be moved (but then usually require complex picture adjustments to get the three images to line up correctly). LCD projector using LCD light gates. Microvision laser projectors use Microvision’s patented laser beam-steering technology, whereas Aaxa Technologies uses laser diodes + LCoS. Obsolete technologies Do-it-yourself video projectors Some hobbyists build a do-it-yourself (DIY) projector for low cost. This is the oldest system still in regular use, but falling out of favor largely because of the bulky cabinet.
