Jeffrey Blizzard shares on Thingiverse:
I modeled this COD Ray Gun to be lit. I made the internal hollow to allow the passage of wires.
I used an over-head transparency painted clear blue for the visible part of the plasma chamber. The side gauge translucent parts were cut from a 1gal milk jug. The sound effects and some lights were from a $3 fake light saber I found at Target. I used two separate circuits for the lighting and sound. The switch on the side turns on the main lighting (blue, red, green and yellow). the trigger is a momentary switch which is linked to 2 AA batteries housed in the side gauge parts. This area also has the speaker and the sound board from the fake light saber. I also had to file down the hinge so that it would properly open and close.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
