LED Color Sensor is a do it yourself designed to assist users who are blind or have low vision identify colors in their environment. It is made by adding a fiber optic cable to a smartphone case, allowing the phone's camera to act as the color sensor. Modern smartphones have lots of good accessibility features that can read out what's on the screen. 

  • The fiber optic is an inexpensive TOSLINK audio optical cable.
  • The author used polymorph (plastic that can be molded at low temperature) to stick the fiber to the phone.
  • To get the polymorph to firmly adhere to the surface, the author added a few holes in the case to create a rivet-like joint.

Author notes: 

  • Avoid damaging the cable by over bending it.
  • The author was able to use some of the spare able covering to fit over the cable tip to make it softer and seal better against a surface. 
  • Carefully line the fiber up with the camera but, be careful not to scratch it.
  • Create a good seal around the camera to prevent other light from getting into it.
  • Try to make sure the phone will still lie on a table nicely.
