FDL-2 Blaster

thingiverse

The FDL-2 is the cutting-edge successor to the FDL-1 Robotic Foam Dart Launcher, boasting improved functionality over its predecessor. It's designed to accept Nerf brand magazines and Elite size darts, firing them at a rapid pace of up to 8 darts per second, thanks to its fully automatic mechanism with adjustable rate of fire. The FDL-2 also features select fire capabilities, allowing you to choose from bursts of 1, 2, or 3 shots in addition to full auto mode. At the heart of this advanced blaster is a Particle Photon microcontroller, which is similar to an Arduino but boasts built-in Wi-Fi for seamless code flashing without the need for a USB cable. This allows users to fine-tune their FDL-2 on the fly using a phone app or web page. Brushless outrunner motors propel the darts with precision, powered by electronic speed controllers (ESCs). The blaster's pusher mechanism relies on a stepper motor, enabling limitless tuning options and complete reprogrammability of the entire system. With Wi-Fi connectivity, users can access a wide range of functions and settings remotely. For those who want to build their own FDL-2 without worrying about soldering or sourcing parts, there are various kits and electronics bundles available on projectfdl.com. These bundles include pre-assembled electronics, tested and pre-flashed with the latest code, ensuring a hassle-free experience for users. The FDL-2 has three distinct versions: the original stepper motor model, the 2+, and the 2X. To build an FDL-2+, print all files from this thing and the 2+ remix. For an FDL-2X, print all files from this thing and the 2X remix. If building an original stepper motor FDL-2, use the versions in the stepper motor remix instead. The blaster requires a 3S LiPo battery with an XT60 connector capable of delivering at least 25 amps for sustained periods. An example is a 1000mAh battery with a 25C constant discharge rate. The battery must fit inside the grip cavity measuring 24mm x 36mm x 94mm. Print settings for optimal results include: * Printer brand: Printrbot * Printer model: Simple Black * Rafts: No * Supports: No * Resolution: 0.254mm * Infill: 20% * Notes: Print at a layer height of 0.2mm with 20% infill. A wide brim is recommended for tall parts or those without adequate surface area. Minor cleanup may be required after printing, including drilling out holes and tapping screw threads.
