Snowflake Gear Wreath




About: I am an author and a maker. My current project is Santa's Shop. I'm working on a science fiction type book--more later. @EngineerRigsby

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

Blue led strip lights

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



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!
