WHEN THE LIGHTS GO AWAY, THE WALL CREATURES COME OUT TO PLAY! Create your own light patterns that dance in the dark with this rotating light projector. How creative can you get? Can you build a constellation that rotates as though it were above you in the sky? Personalize your creation and control its speed and direction wirelessly.

These instructions correspond to the first edition of the Gizmos & Gadgets Kit. If you have the Gizmos & Gadgets Kit: 2nd Edition, please refer to those instructions. They can be found here.

How To Make It

1

You’re going to build two circuits that communicate with each other wirelessly. First build the ROTOLAMP CIRCUIT. Set the DC motors to VAR (variable) mode.

Now, PRESS THE CIRCUIT ONTO THE MOUNTING BOARD. Make sure the mounted circuit looks just like the image below so everything fits nicely for the final build.

Start building the TRANSMITTER CIRCUIT.

Finish the TRANSMITTER CIRCUIT by adding a POWERSNAP to the middle bitSnap on the transmitter circuit. Then, press onto a mounting board.

TURN OFF THE PROJECTOR CIRCUIT AND ADD WHEELS TO THE DC MOTORS. The wheels will help you spin your projector and provide the structure for the projector to stand on.

6

Stand the Rotolamp up with one wheel as the base and TEST OUT YOUR CIRCUIT. Make sure the wireless receiver is on the SAME CHANNEL (a,b,c,d, or e) as your transmitter. Use the transmitter circuit to spin the projector!

Build the ROTOLAMP SLEEVE from templates E1 and E2 and place it on top of the Rotolamp circuit. Make sure to turn off your Rotolamp circuit while building the sleeve.

PLACE YOUR ROTOLAMP IN A DARK ROOM near a wall. On both circuits, turn power on and watch your invention illuminate the walls.
