DoubleU-Foam-Dart-Launcher

thingiverse

I'm planning some new features with an estimated release date of autumn 2017. These features include modified housing, which incorporates the dart chamber part into the main body, and dart sensors using IR technology for more precise movement. The current software has hardcoded this feature. To enhance user experience, I'll add an additional pre-trigger button to spin up the wheels before firing or keep them spinning. This will make it easier to launch darts accurately. I'm also planning to create a body version compatible with other motor sizes, such as 1106. Progress update: on December 16, 2016, I published my firmware on GitHub due to the community's request. Please go easy on me since I'm not a professional programmer. You can find the source code here: https://github.com/willumpie82/DUFDL Another progress update: on December 15, 2016, I migrated from ESP8266 to Teensy3.2 (Cortex M4) due to its improved performance. The firmware is now functional, but it needs some polishing. I'll create a GitHub repository for all the source files soon. Meanwhile, the 208-GT2 belt is still in development because the current 200-GT2 belt is too short. I'll release the accessory top mount soon. My design was inspired by JesseKovarovics' FDL-1 and FDL-2 dart launchers. I've added some unique features to make it my own. Although the firmware is not yet finished, it will receive some small modifications. Currently, I'm writing the firmware for an ESP8266, but I'm waiting for an i2C IO extender since the ESP is short on IO. The device can run on an Arduino, but due to PWM signals, it runs out of clock ticks (16Mhz). Here's my shopping list: https://github.com/willumpie82/DUFDL/blob/master/BOM.xlsx Controlling Settings include: * Launch mode: Single, Double, Triple, Full Auto * Launch speed: 0-100% * Clip size: Countdown This design is a work in progress, but most parts already function. Soon, I'll make the source code and design files available (Solidworks). Print Settings: * Printer Brand: Ultimaker * Printer: Ultimaker 2 * Rafts: No * Supports: Yes * Resolution: 0.2 Notes: Most body parts are printed in PLA with 10-30% infill, while flywheels are made of ABS with high infill for better balance. Although the designs are made with 3D printers in mind, I'm having trouble getting the orientation correct on Thingiverse. To assemble the design correctly, place all parts with their flat sides facing down. Support: * The body, grip, rear side panels, and barrel connector require support. * It's best to print the clip holder without support since the internal cavity (for locks etc) are small enough to bridge. Any support here is impossible to remove (resolvable support will work). Post-Printing: I designed this dart launcher with a unique combination of features that make it easy to use and customize. The design process was challenging, but I'm excited to share my creation with the community.
