I have finally finished my500mw green portable projector.
Internal LifePO4 batteries power this projector for about 1 1/2 hours.
506 scanners, Modified red boards 1 lens, & 1 mirror gives it a very fine well controlled beam.
I optimized this laser for the best possible efficiency of DC power using a variety of dc/dc converters
adjusted to the needs of each system.
The total power consumption running an animation at 500mw out the window and 8*+ scan width is 60 Watts.
Besides the normal safety systems, this projector senses motion and will shut down rapidly if it is moved beyond a
very limited range. It s therefore functionally inoperable as any kind of "Pointing Device".. This same system locks
the projector in shutdown condition and only a certain sequence of tilts and rotations will unlock it.
A few pictures. I will provide more details in time.
