Star Trek Phaser

thingiverse

As a small project, we decided to design a Star Trek-style phaser inspired by the styling of Star Trek: TNG. This project includes space for working laser modules that resemble the ones used in the popular science fiction series. **WARNING:** LASERS ARE EXTREMELY DANGEROUS AND CAN CAUSE SERIOUS DAMAGE TO VISION, EVEN LEADING TO BLINDNESS. ALWAYS WEAR LASER SAFETY GOGGLES WHEN WORKING WITH LASERS. DO NOT FIRE LASERS AT PEOPLE OR ANIMALS. 250mW LASERS ARE POWERFUL ENOUGH TO BURN PAPER AND WOOD. **PARTS REQUIRED:** * 250mW Laser Module (12mm dia.) * Generic momentary push-to-make switch * 18650 Battery * Charging Board for 18650 battery * Wiring The laser module fits inside the grip, while the switch locates between the fire button and the cover part. A small slot is provided at the base for the micro USB connection. **ASSEMBLY:** 1. Fit together handle parts. 2. Guide wires through handle parts into switch compartment. 3. Secure charging board to base of handle parts. 4. Connect 18650 to charge board and switch wiring. **Be extremely careful not to short out the cell at any point, as this can lead to a fire hazard.** 5. Fit laser diode into nose part & attach to handle. **Leave enough wire to connect laser diode to switch.** 6. Connect switch in series with the positive terminal from the battery and the input of the laser diode. **The switch's connections should feed through the small hole in the base of the cover part.** 7. Attach fire button part to top of switch. *The switch should friction fit between the cover and the fire button, but in case of a loose connection, a small amount of adhesive works just fine.* Side note: the fire button will only locate into the cover in one orientation. 8. Connect output of laser diode directly to negative terminal of the battery 9. Coil up excess wire and insert cover section through the underside of the handle. *This is a snug fit, sanding may be required* 10. Fit grip piece over 18650 battery. *The battery doesn't have much room to move, but we'd suggest securing it to the handle with a small dab of adhesive* 11. Glue buttons into panel 12. (Optional) Boldly go where no one has gone before!
