The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. In this kit, you will be able to demonstrate and visualize how the earth orbits the sun and how the moon orbits the earth. While you're at it, let your children build it themselves while learning how to hook up some gears and DC motors.
Note: Download the softcopy instruction manual (English) here. 
The kit is also paintable which makes it exciting! Let your children paint the planets after assembling the wooden structure.
Features:
- Do It Yourself Wooden Sun Earth-Moon Orbit

The VL53L0X V2 time-of-flight range-finding sensor is a new generation of laser ranging modules. The VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source and a matching sensor. The VL53L0X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining the distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53L0x is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.
The VL53L0X can handle about 50mm to 1200mm of range distance, yes, that is 1.2 meters :)
The sensor is small and easy to use in any robotics or interactive project. Since it needs 2.8V power and logic we put the little fellow on a breakout board with a regulator and level shifting. You can use it with any 3-5V power or logic microcontroller with no worries. Each order comes with a small piece of header pin. Solder the header onto your breakout board with your iron and some solder and wire it up for instant distance-sensing success!
Communicating to the sensor is done over I2C with an API written by ST, so it's not too hard to port it to your favorite microcontroller. We've written a wrapper library for Arduino so you can use it with any of your Arduino-compatible boards.
