High light

Image playing tennis, wearing a special bracelet: when you swing fast, your bracelet lights up. And the stronger you swing, the brighter the bracelet will light up. 

Step 1: Materials

• Xadow M0                  
  
• Xadow Breakout
  
• Lithium Ion polymer battery
  
• Digital RGB LED Flexi-Strip（here we only use six LED）
  
• Elastic 
  
• EPE
  

Connecting hardwares

Connect the Xadow breakout and Digital RGB LED Flexi-Strip: you will need three wires.The LED strip has two ends: weld so that the arrows point in opposite directions.

After welding the three wires to the end of LED strip, weld the other end of the three wires to theXadow breakout:

• GND to GND
  
• 5V to 3v
  
• DO to MISO

Connect the Xadow breakout and Xadow M0. These two modules are connected by FFC, pay attention to the connection direction: the unfilled corner of one Xadow module need to connect to the right angle of another module.

Finally, insert the plug of the battery in the socket on Xadow M0.

• Quick press the button, the program will be running
  

Shell Design & Assembly

Download the Shell file here.

Enclosure model file（stl）：MISSING LINK?

Enclosure 3D printing file(3xg）： MISSING LINK?

Download the Enclosure 3D printing file and import it to the SD card, then you can printing the Enclosure with the SD card.

After 3D-printing is complete, assemble the shell parts with rivets and an axle.

Assemble the hardware into the shell.

There is gum on the back of the led light bar: stick it on the upper surface of the shell.

In order to facilitate wear, the elastic band should be installed on the shell. Then add a layer of EPE in LED light bar as a soft shade, increased halo effect.
