Ghost Light Insert

thingiverse

A friend wanted me to print out this ghost ( http://www.thingiverse.com/thing:426237 ) and asked that it be lit up as well. So with some spare time in Tinkercad, I managed to design a LED holder from an old computer fan LED housing that I had been holding onto. If you've got one lying around and are looking for a fun crafting project, this is a great place to start. \n Instructions First: Locate a discarded computer fan with four working LEDs and take it apart. Set aside the circuit board and LEDs. Remove the motor windings from the board using a soldering iron, revealing four posts that hold the motor in place. Second: Print out the LED holder and attach the battery tray to the flat side of the ring circuit board holder. Place the circuit board on top and secure the Leds within their new housing using glue. Third: Bend a paperclip into a circular shape that fits through the bottom of the battery compartment and out the other side, making contact with the watch batteries that will be powering the LED lights. Additionally, glue a straight section of paperclip to serve as an alternate contact on the opposite side of the batteries. Fourth: Assemble the circuit by soldering a slide switch into the back of your Ghost's eye socket. Remove part of the rear cap to create room for the switch and then make all necessary connections to complete the circuit. I have also provided a defuser to soften the intensity of the LED lights, which will prevent direct glares and harsh shadows on the surrounding environment.
