HowTo: A low cost lighting sequencer (Pt 1)
( Roger Otis)
Step 7 : A Project
|
| | A project is needed to demonstrate the use of the basic circuit. It is the tree shown at the beginning of this How To. The tree appears to have rotating lights.
The main support is a piece of wooden handrail about 8' long purchased from a home improvement store. It is painted black. A star with 35 blue lights is placed at the top of the pole. Holes for the lamps were drilled about ¾ inch in from the perimeter of the star. Slots were cut from the perimeter into each hole for wire clearance. Lamp bases are pressed into the holes for a friction fit. A bolt and nuts were used to stand the star off the pole about 1 inch. A 6 inch disc made of 3/4" plywood was added below the star. Holes were drilled at 18 degree intervals around the perimeter of the disc. Pieces of bare #12 copper wire were used to form a hook for each hole.
