+LED lights for bicycle wheels.
16 multi color LEDs on each side (PCB top- and bottom side).
There are two windows (upper and lower) on each side for display 
dynamic information like speed, trip time, trip distance, etc. or
static information like strings and images.

+It is possible to mount the PCB direct onto the wheel spokes but it is 
better to use a mounting frame. This frame can be ordered from
http://shapeways.com or you can print it by yourself on 3D printer. 

The Printed Circuit Board (PCB) is free hardware. The PCB is a multi-layer (4 layer) 160 x 30.5 x 1.6 mm FR4 board. The firmware for the MK22DX256VLF5 MCU is also on GitHub.

There is also an optional Bluetooth Low Energy (Smart) subsystem on board. 
It is a LAIRD BL600-SA module. The Bluetooth application software is on 
GitHub too.

 CAD Tool 

EAGLE from CadSoft is not free software. But there is Light Edition. With this edition you can at least view and print the drawings. The Design exceeds the limits (100 x 80 mm board size) for the Light Edition, therefore you can not edit/change the design. There is also EAGLE Make Personal edition, with this edition you can edit the design for about 140 € (only for non commercial use). See EAGLE Pricing Table for other licenses.

Maybe the free KiCad can be used to import the design.


 How To Build or Order Frames 

I ordered my frames from PCB-POOL, they accept the EAGLE design files (e.g. ewheel32.brd) and you do not have to generate you own Gerber and Excellon drill files. 

Some ordering information: 

 Length in mm: 160
  Width in mm: 30
  File format: EAGLE
  Base material: FR4, 35 µm Cu, 1,6 mm
  Soldermask: inclusive
  Position print / Silkscreen: yes, TOP and BOTTOM
  The price includes silkscreen for 36.65 EUR
  Surface: ENIG (Electroless Nickel Gold) for ultra-flat pads
  Min. track / gap size: >= 0.150 mm (6 mil)
  Min. drill-end diameter: >= 0.3 mm (12 mil)
  E Test inclusive
  Free Stencil: yes
