Inspired by the featured flashlight projector, I scaled this up and added a mount for a motion detector LED array.
1lb of ABS and 12hrs printing later, I had a working model.
However, had to put aluminum foil over all but one LED to make it visible and focused.
Would not hurt to have another 5 or 6 inches of focal length.
The motion detector is a Harbor Freight item with solar panel to keep batteries charged.
