When I mean cheap, these laser projectors are cheap. I bought 4 because the reviews say you'll need spare parts. I got 2 duds. The green laser doesn't work on one and the other's motor already went. Not a big deal considering people are spending considerably more and having the same issue of one of the lasers not working.
Step 1: What You Need
Dowels. I had some scrap square dowels laying around.
Plastic container big enough for power strip.
Step 2: Remove Top Adjustable Mount
Remove the top adjustable mount. Cut the dowel to fit in the mount. Screw it to the mount.
Step 3: Cut Mount for Laser Projector
Cut a piece that fits in the container to mount the projector to. Drill holes for zip ties. Screw it to the the top mount as shown.
Step 4: Mount Laser Projector
Mount the laser project with zip ties. Laser should be flush to inside wall.
Step 5: Vent Holes
Drill holes in the bottom for venting and power adapter. I did them at the back because these things will be tilted up. If water does happen to get inside, it should drain.
Step 6: Add Stake
Cut stake. Screw to mount as shown.
Step 7: Powering It
I had an outdoor power strip with a stake. I cut a hole in a plastic container for the plugs and stake.
Step 8: Adjust Motor Speed Done
I made three. I ran out of wood so I attached a plastic rod that I found. Set the motor speed to your liking. Zip tie shut, nice and tight. Done!
Step 9: ***Bonus - Camera Tripod
Comes with a little bendable tripod that fits cameras. Not bendy enough to attach to things like what a gorillapod does, but it is useful.
