I don't feel like tearing apart an other DVD drive.


I have been playing around recently with the idea of creating a handheld laser that can actually do damage. Ex. popping balloons, igniting things, etc. basic schematics for wiring. In fact, the majority of this project was derived from the linked-to website. What remain to be purchased are the project box and switch and possibly a diode to help regulate power.


  • needed: new laser diode
  • a laser diode housing
  • a threaded collimating lens
  • the associated heatsink for the diode
  • the 10-15mW laser diode that came with the assembly
  • a battery housing for the completed construction
