2015-06-10 (W) Vibrating Distance Sensor

After plunging into the first prototype so quickly some documentation had to be done including electrical schematics which were hand drawn on graph paper during a work break. Working without keeping careful documentation is faster but makes reproduction more difficult. By carefully documenting each step of the process someone could recreate this project with little difficulty so a second prototype will be built for two reasons. The second prototype will have less "rework scars" and be slightly smaller since it will not have a small piece of stripboard like the first prototype. The enclosure, shown below, has been designed around a more compact version.

Electrical schematic

The dimensions of the electronics were measured and an enclosure was designed using existing models. Instead of making the box dimension to match the distance sensor, which was the largest component, this enclosure matches the 9V battery holder. By matching the 9V battery enclosure the components inside can be assembled, inserted and glued in place, also called "potting." This should ensure that the components are held in place even if they are dropped or mishandled. On a short side of the enclosure a part of the wall has been removed to allow access to the USB port. Access to the USB port allows for reprogramming later and the device can be powered by a portable phone charger like the Self Contained Haptic Distance Sensor.
