Re: DTR's Laser Shop
I was hoping to copy your 32650 eghemus build. If its ok with you, I'd like to use the same rectangular heatsinks as you did in your build. I was thinking you could solder the wires and set the current for me and I'll just attach the heatsinks later once I buy the host from...
Hey SHIN, do you happen to have a circuit diagram for the test load you constructed? I know that you used these parts:
7 of 1N5404 (3A, 0.7V voltage drop)
4 of 2W 1ohm resister(=1 of 4W 1ohm resister)
1 of 2W 2.7Kohm resister
but I just wanted to make sure how to connect them. Is everything in...
Hi, I wanted to ask someone for help on how to build a high current test load. It seems like many of the test loads we have for red and bluray tend to get hot when running above 1 amp. Is it possible to build a test load capable of handling up to a couple amps continuously without overheating...
It is certainly possible to light the paper to open flames.
My 1.6 watt build has no problem igniting thick paper. My 1.2 watt build was only barely powerful enough to ignite magazine paper. In my experience, magazine paper ignites more easily than plain printer paper. Although, with enough...
I agree, he banning him was the right decision. It's obvious that the laser did not meet the advertised specifications. On top of the customer service issues, I see no reason to purchase from him unless the quality could be guaranteed. So far, they've missed the mark.
Also, he shouldn't assume...
@Spartan X
If you are using a flexdrive, you can just turn the pentiometer to its maximum setting. Just make sure you have adequate heatsinking on the diode and driver.
If I were you, I would not point a laser of any power directly into my eyes. The truth is that even if the laser is advertised as 5mw, there's really no way to be sure. Especially since it's 980nm, it probably won't be that visible. If I were you, I'd point the laser at a sheet of paper and see...
In general, as long as the laser is well below 500mw, it is safe to look at the diffuse reflection. However, the goggles are there in case you accidentally hit a reflective surface. If you're using it without goggles, don't point it at glass, metal, or shiny plastic objects.
In addition, if...
Re: FS: Optotronics 150mw Pen
Thanks for the encouragement, Moebius. This is a great laser and can't be compared to the cheap stuff on less reputable laser sites. If you guys have any questions about my rep as a seller, PM drummerdimitri. He bought my jayrob 445nm laser and payed through...
