My dealextreme $17.24 red laser module has died...

Razako · Mar 4, 2008

Turned it on today and it put out around .3mw of red light and the heatsink gets really hot. The last time I used it was when I made this video. I had it running off 5v DC and the pot was maxed out. W/e it was fun while it lasted and $17 isn't much of a loss.

On the bright side now you have a nice heatsink to do whatever you wish with!

yeah you can always pop an open can in there

just after i read this thread i turned on my dx70 and it was dead just like yours (**cursed**)

I guess maxing out the pot isn't very good for it... probably what you would expect as it is set to a lower level from the factory

How long did it last in terms of total runtime?

At least 20 hours. In a test I left it running for 15+ hours with no problems and the day after that it still worked fine.

20 hours.. not great, but not crazy bad either considering you maxed it out. Good to know though, putting the power up a bit seems fine for playing around a bit but not for any permanent application.

Did you have a chance to take the module apart yet? I'm wondering how hard it is to replace the diode in these.

Damn I just tested mine and thought it had died as well but it was just dead batts

I did take it apart and it looks like you could easily replace the old diode with an open can assuming it fits.
I can post a picture of the completely disassembled unit if anyone cares.

Please post some pictures, always nice to have!

I reckon it will fit, common sizes are only 5.6 or 9mm for this type of laser diode, and the difference is easy enough to see.

I'm pretty sure you could throw another diode in there, for something that cheap the parts would have to be pretty standard. I wouldnt be suprised if it was just a form of aixiz module.

Mine died with a small pot mod not completely with 5 min of run.Then i bought a second one and did no pot mod and it broke after 5 minutes.I used 4 aa.

I use these ones for their parts, and have noticed that there is an issue with the driver board. I havent tested them, but avoid using the boards all together.

Re: My dealextreme $17.24 red laser module has die

I have three dx 70 units and I immediately maxed the pots on all of them. Soldered the driver leads to old usb connectors and plugged them into the computer. After about 5 hours of use each, they are still working fine. What exactly is the problem with the driver board? I haven't noticed anything.

i've heard of touchy pots when adjusting can send full power to the LD and kill it

I replaced my blown one with a SenKat red, no problem.....

i've heard of touchy pots when adjusting can send full power to the LD and kill it

That is what killed the original....and the SenKat the pots are crap, IMO
