Parking Sensor

In Action

Back Story

The overall point of this project was not to make litho boxes but that is what ended up happening. I wanted to make lights that would alert my wife andI to how close our truck was to the wall when parking in the garage. I modified the sensor code off the Arduino website and made some litho boxes to be illuminated by the LEDs.

The Boxes: The boxes turned out to be quite awesome. I realized when I was making them that these could also be used as a decoration to spell out someone's name or to make a cool custom lamp.Each box contains a LED and a wire that runs to the board. The boxes have a passthrough channel so the wires are hidden. Each litho pane slides in so you can change them without removing the boxes. Be careful when printing as there is a left, right and middle box. Make sure that when connecting your LED that you use a resistor that is suited to your LED.

Litho panes: I used paulbovbel litho pane customizer and in my slicer. I made them .75 of the original. The panes, as I said above, are able to slide into the the boxes without removing the boxes themselves, enabeling you to change what appears easlly.

Thank you paulbovbl! LINK----> http://bit.ly/SWEETLITHO to his page.

Not included: I did print a case for the arduino and the ultrasonic sensors; however, since I did not make these I will not include the files. A quick search and you will find many suited to your needs.
