Published on April 23, 2014

Build an intelligent vehicle with multiple functions. This honking tricycle beeps until you make noise. When you make a noise the beeping stops and the wheels are set into motion.

How To Make It

STEP 1

Start with this circuit: power + sound trigger + RGB LED + latch + wire + DC motor + wire + inverter + pulse + buzzer

STEP 2

Cut foam core base using box cutter and ruler. We cut a piece 4 inches by 7 inches.

STEP 3

Cut slot down center that is wide enough for a piece of foam core to slide in. Make sure to leave space that can be the back of the bike.

STEP 4

Make axle holder with foam core and glue to the back of the base.

STEP 5

Punch holes in the side and attach to the base.

STEP 6

Make back wheels. Trace a cup and cut out 2 circles. Try different sized circles for your wheels.

STEP 7

Make the back axle. Poke skewer through circle and put a dab of glue to hold in place.

STEP 8

Carefully cut the point off.

STEP 9

Thread axle through axle holder and then add the other wheel.

STEP 10

Make and mount the front wheel. Cut out a larger wheel and stick the popsicle stick through the center. Glue the stick to the wheel.

STEP 11

Cut off end of popsicle stick then attach wheel to motormate.

STEP 12

Place littleBits on top of base. Tape modules down to the top and tape the battery to the bottom.

STEP 13

Decorate and ride on! Make a loud noise to ride on, make another loud noise to stop and honk.
