CUBESCUBES

Bring your toys to life with Circuit Cubes, the electronic

building blocks that add power, motion, and light to your

creations. Designed by STEM teachers, Circuit Cubes can

turn a light on, power a motor, or make wheels spin — plus,

they work with your LEGO® bricks.

The standard battery Cube is the power for your circuit.

It has a positive and negative terminal. Just turn on the

switch to power your creation and it's rechargeable

too. If the LED on the top of your cube is flashing red

then you have caused a short circuit and power output

is disabled to allow you to troubleshoot the circuit.

The Red-Green-Blue (RGB) LED has three different

LEDs in one bulb. Use the small switches to turn

on each of the different LEDs, and control the red,

green, and blue lights. Try mixing the colors together

to get different combinations for purple, teal, and

yellow lights.

A perfect fit for your LEGO® gears and wheels, this

mighty little motor actually rotates at more than 1,000

RPM (rotations per minute), but the tiny gears attached

to the motor shaft reduce the rotations to about 100

RPM. This ensures maximum torque to turn the wheels

or gears of your projects.

You won’t find +/- signs on the motor cube because direct

current (DC) motors, like this one, can accept current in

both directions. If you wire it up one way, it will rotate

in one direction. Flip your wires and it will spin in the

opposite direction.

A single Motor spins all four of Dune's wheels. It accomplishes this using idler gears between the driving gear & two driven gears.

Dune's drive train uses two sizes of gears: 8-tooth & 24-tooth gear.

We can compute Dune's gear ratio by focusing on the three gears in the highlighted blue box that drives the front axle.

A 1:1 gear ratio means that the Motor & the wheel axles spin at the same speed.

WORMWORMGEARGEAR

Worm gears can easily turn other gears, but other gears cannot turn worm gears.

Worm gears drive axlesand are perpendicular to the input axle.

The worm gear is effectively a 1-tooth gear, used to increase torque.

Gator may not be the fastest, unless in an uphill race.

Blur uses two stages to get two speed increases. Each stage has a 24-tooth driving gear and an 8-tooth driven gear.

86

For each stage, the 8-tooth axle is spinning 3 times faster than the 24-tooth axle. The axle from the first stage, now 3 times faster, is the input to the second stage. Again, the speed is increased 3 times, for a total gear ratio of 9:1.

The wheels are spinning 9 times faster than the motor!

BATTERIES The battery is non-replaceable. Do not attempt to

replace the batteries yourself. You may damage the batteries,

which can overheat and cause injury. Do not expose battery to

water or allow the battery to get wet. Circuit Cubes are only

intended to work with one Battery Cube in a circuit — parts may

fail if you add multiple Battery Cubes in a circuit.

DISPOSAL The lithium-ion polymer in your Battery Cube

should be recycled by Tenka Inc. or an authorized service

provider. For more information about Tenka Inc. lithium-ion
