Diy laser pointer driver

 · Laser Diode Driver Circuit Normally, laser pointers are operated with 3V or V V DC supply. You can adjust the output of the circuit to precisely V. Since it is 5 watt, so the current for the laser will be 5 / = amps As per this current, you will have to use a R3 resistor with a value = / = ohms, 1 wattReviews:  · Welcome to Laser Pointer Forums - discuss green laser pointers, blue laser pointers, and all types of lasers Home. DIY Homemade laser diode driver. Thread starter Daedal; Start date Jul 29, @oldscooliron, LDs (or LEDs in general) are current-driven, not voltage-driven - you set a certain current on the driver and don't worry about the User Interaction Count: K.  · How to make a laser pointer for less than $2. The only things I had to buy were some button cell batteries, and the laser diode. I got them both off eBay for Author: How-to Honcho.
