After a late night an Instructable was written from beginning to end. Over 1,200 words were written which does not include text copied from this blog. There was an attempt with this project to draw people in with a short scenario which quickly showed the function and benefit of a handheld distance sensor. In the scenario the reader is trying to keep from disturbing a light sleeper in an unfamiliar room and must navigate without lights. Sonar, bats, and caves are also mentioned to help imaginations run. There was no mention of vision-impaired people benefiting from this device in the Instructable.
Completion of the Instructable closes this project and it can be considered a success. In the future this could spawn another distance sensing assistive device. Improvements to the ultrasonic distance sensor would help since the current sensor can fail if the surface being inspected is at an oblique angle. A higher speed reader and a more responsive feedback device would also be helpful but more expensive.
