The FDL-2 is the successor to the FDL-1 Robotic Foam Dart Lancher. It is similar in function but instead of “Mega” sized darts firing from a revolver, it is designed to accept Nerf brand magazines and Nerf “Elite” size darts. It is fully automatic with an adjustable rate of fire up to about 8 darts per second. It also has select fire allowing you to fire in bursts of 1, 2, or 3 shots in addition to full auto. The entire FDL-2 is controlled by a Particle Photon microcontroller. The Photon is very similar to an Arduino except it has built in wifi allowing you to flash new code to it without plugging a USB cable into it. Darts are propelled by brushless outrunner motors which are powered by electronic speed controllers (ESC’s). The FDL-2 uses a stepper motor based pusher mechanism to push darts between the flywheels. Between the microcontroller, stepper motor, and speed controllers the FDL-2 has a limitless set of tuning options. The entire blaster can be reprogrammed to operate in any way. Having wifi also opens up the possibility of using a phone app or web page to fine tune the function of the blaster on the fly.

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!
