!!!! My uber-laser just decided to turn itself into a regular laser pointer... I guess that's it for me and lasers :\ It was fun while it las[t]ed though Lesson learned: never run high-powered lasers without proper heatsinking

The laser module is from DX, and based on what I've seen and read, I'd say it's the same as the Aixiz (which I have no experience with). Currently, the laser module, or actually the metal focusing ring, extends 2-3mm from the front of the flashlight. The measurements of the flashlight as taken...

Laser diode arrived today! I tried my circuit and measured around 125mA going to the diode at almost exactly 2.5v. That measurement was probably not accurate because I put my meter on the 500mA range, and it's analog. I'm not sure what output wattage this is, but it burned the black lid of my...

Re: Will this work for powering a laser diode? another picture and uh.. there's no real heat sink. it's just a washer badly soldered (it's my first time doing something like this) to the module :]

Re: Will this work for powering a laser diode? I got my 5mw laser module and flashlight today! So far, I have gotten the circuit up, but I'm still experimenting with the placement of the module in the flashlight. For the circuit, I'm hoping that the laser won't eat more than it can chew with my...

Re: Will this work for powering a laser diode? Yay, I received my chip samples today! - LP38690DT LDO Voltage Regulator (2.5v, ~1A?) - LP3878MR Adjustable Voltage Regulator (1.0-5.5v, 800mA) I tried out the 2-pin 2.5v regulator on a regular red led (heh, Overdrive!) and measured around 45mA...

Hey, I have a big soldering iron too, and it has a fat chisel tip! I could still solder wires to a surface-mount 7404 chip (14 pin) even though the tip was as wide as the chip itself! However, the chip refused to work anymore after I soldered it   ::)

Re: Will this work for powering a laser diode? The light I'm using is DX's famous MTE SSC P4 light, loved by many. However, I think its output sucks, so I'm going to shove a high-powered laser into it  ;D And uh... my measurements were made by shorting the multimeter on the output with no LED...

Re: Will this work for powering a laser diode? If I'm going to be using only 1AA, then of course I'm gonna keep the boost circuit that's already in the flashlight. The problem that I have now is limiting the current to the laser diode. I don't think I can use the LM317 because the voltage...

Hi! I've been reading a few threads here and finally decided to register. I paid for the 16x DVD laser diode, and I'm just trying to find some suitable way to power it. I plan on putting the whole thing in a 1AA flashlight, so my choices of batteries are either AA or 14500 Li-Ions...
