Introduction: Snowflake Gear Wreath
This "back lit moving gear" wreath was created to replace a dull wall hanging in Santa's Shop. Santa's Shop is an animated, story telling art installation available for public viewing in the window of Brightway Insurance Agency from 5:30 P.M. to 9 P.M. daily during December of 2018 at 9127 SW 52nd Ave, Gainesville, FL 32608.
Step 1: Materials
Quimat metal gear servo motor (this has no end stops and is easy to convert to continuous rotation)
(7) 6mm x 19mm x 6mm bearings
12" x 10.5" plywood (1/2 inch thick)
(4) M3 x 8mm screws
12 volt dc power supply (for led lights)
3 volt power supply (for gear motor)
(24) 3/4 inch wood screws
Paint
Glitter
Fake jewels
3d Printed Parts
(7) bearing mounts
(4) corner bkta
(1) drivegear short
(1) servo gear motor
(7) nut105 (print at 105% size)
(1) servo horn short
(7) snowflake gear
Step 2:
Remove four screws from the servo motor (this metal geared servo motor has no end stops--it is ideal for converting to a powerful geared dc motor).
Step 3:
On the circuit board, cut the two wires from the motor and the three wires from the pot. Remove the circuit board.
Step 4:
Solder wires to the motor wires.
Step 5:
Replace the four screws and you now have a powerful metal gear motor with servo horns for attaching to things.
Step 6:
Press fit the bearings into the bearing holders.
Step 7:
One at a time, mount the gears. Make sure that the gears mesh and turn freely. Secure each gear with a printed nut.
Step 8:
The drive motor and seven driven gears make up my wreath. You must have an even number of gears for a closed gear system.
Step 9:
Fasten the corner standoffs to the plywood using wood screws.
Step 10:
Test the operation, then remove the gears and paint the wood. For anyone interested, the blue scrap plywood I am using was part of the "swamp" in Froggy World.
Step 11:
Attach the lights to the rear (peel the tape and stick them on). Add paint, glitter and "jewels" to suit your taste!
