Astronaut LED/laser projector
Cheap toy projecting on the wall or ceiling colorful nebula-like pattern with stars.
Nebula pattern is changing in a seamingly random way and changing color between red, green and blue. Star pattern (generated by laser) is stationary and just pulsating.
Just mechanical damage: torn out laser wire, broken plastic latch holding LED unit.
LED unit generating nebula pattern. It uses RGB LED and small DC motor identical to used in CD-ROMs as a tray drive.
Nebula effect details from similar projector. Glass disc textured on both sides is placed in front of RGB LED and rotated by motor with gear system.
Since LED structure for each base color is placed in slightly different position, it directs light in slightly different angle, generating different semi-unique
patterns.
Star effect: laser + diffractor.
Controller PCB.
I'm not sure if this IR receiver works at all - there no window in front of it and this plastic does not seem to IR-transparent. Overall it seems like PCB is not matching
the shell.
DC jack quality is poor. There is a lot of empty space inside shell, I'll think of adding panel-mounted USB socket in parallel later.
In default mode it consumed about 350mA from 5V power supply.
