The TARO is a select-fire, Arduino controlled, solenoid-fed, flywheel-powered foam dart blaster. It was designed to provide full-size performance in the smallest package possible and unapologetically present as a flywheel blaster.

Aside from hardware, motors, actuators, wires, and the Arduino, the blaster is 100% 3d printed. Due to relatively compact package and tight tolerances, a well-calibrated 3d printer is recommended. We are working on sourcing hardware packages to simplify the assembly process. Tested in PLA and PLA plus. Other materials may work fine.

Please refer to the assembly guide for the full BOM, electrical schematics, print orientation and settings, and assembly instructions.

SPECIALTY PARTS REQUIRED (not including hardware):

  1. Worker Angled Talon half-dart magazine (short and extended lengths work fine. Included baseplate works intended for use with short magazine)
  2. 4x RapidStrike/Stryfe flywheels
  3. 4x OutOfDarts Kraken motors (other motors have had electrical issues)
  4. Graphene 0.95 Ah 3s LiPo battery (designed around this battery, which is apparently out of production. Any 3s LiPo smaller than 78x26x22mm will work, like this one)

Here is a cross-section of the battery compartment:

TOOLS REQUIRED:

  1. 3D Printer
  2. Soldering iron  + solder
    1. M3 and M4 heat set insertion tips (recommended)
  3. Wire cutter and stripper
  4. 2mm and 2.5mm hex keys
  5. #0 and #1 Phillips screw driver

Arduino code is available on GitHub
