Are there resources to help individuals who are blind build hardware devices?

Yes. For example, there is a community of individuals who are blind and use the Arduino platform to build hardware devices.  Arduino allows users to build digital devices that can sense and control objects in the physical world. Arduinos can utilize sensors, motors, displays, wireless communications, and a host of other tools to build things like alarm clocks, robots, night lights, and limitless other projects. The Blind Arduino blog has resources and advice for getting started.
