A.R.M.S - A Reconfigurable Maker's Shooter - Mark 1 Pistol This marks a major milestone in my Arduino-based laser tagger system, where simplicity meets precision. The goal of this cutting-edge system was straightforward: it had to be remarkably inexpensive, yet functionally superior, and boast exceptional scalability. To help you delve deeper into the intricate design of the system, I've made detailed posts on the construction, electronic circuitry, and programming for the Arduino board that regulates the tagger. Please visit my blog to access these invaluable resources: http://teslaandi.wordpress.com/2014/09/29/databullets-2-laser-tagger-handgun-mark-1/ Total Cost: Constructing this revolutionary tagger is feasible without denting your wallet; you'll spend less than $20 AUD in total. Building Instructions These precision-printed components are specifically designed to be print-ready without supports. The tolerances aren't extremely critical, allowing for a hassle-free assembly process (only minor adjustments may be required). The post-processing primarily involves drilling screw holes that suit your specific screws. Design Assets: Attached are the schematics and Arduino .ino file that make up the core of the tagger's functionality. Getting Started Gather these key components: Arduino Board: Ensure it has sufficient inputs and outputs (A minimum Arduino Uno is required) Laser Component: Obtain a 40mm lens with a focal length of approximately 130mm. This could be sourced from a similar, more readily available component. Electronic Components: • Full Set of Printed Parts (.STL files are provided) • Arduino Uno Board • Prototyping Breadboard (soldered type for improved performance) • Rotary Encoder (Optional: may be substituted with pushbuttons with minor coding adjustments) • Header Strips • Microswitch (trigger component) • 16x4 LCD Screen (Compatible with the Hitachi HD44780 controller) • 2 x BC337 Transistors • Resistors: • Five resistors of 10k Ohm rating each. • Two resistors rated at 270 Ohms each. • One resistor with a resistance value of 72 Ohm. • A single resistor worth 56 Ohms. • Miniature Potentiometer - with a capacity of 1 kOhm • LEDs: Red and yellow types for varying alerts and feedback • IR LED (940nm, outputting 100mA power in a beam angle of 10 degrees) • Cheap laser diode from eBay • 9V battery pack • Various tiny screws for assemblage
