    BHWOLLEN: Negative transaction

    Sorry about the uppercase, I only copied and pasted the messages I have sent him. He has been avoiding me the past few weeks even though he promised several times to ship the item. He said by Monday 8/8 he was going to send me the tracking number. I have asked him multiple times for the tracking...

    BHWOLLEN: Negative transaction

    I am getting screwed by member BHWOLLEN as well! I was looking for a decent LPM and he offered to sell me his for $120. If I knew if was going to take almost a month to ship I would never have ordered it from him and just spent the extra $20 and got it new. He has also lied to me on several...

    637nm HL63133DG Build

    Thanks DJNY! From the PDF specification I see that at 250mA this diode puts out 170mW (CW) of light output. Fiddy, I see that you are running a microflex drive V5 set at 340mA. About how much light output do you expect to get at that current? You know the maximum amout of current that this laser...

    637nm HL63133DG Build

    I have two 250mW LPC-815 LOC's installed into my laser projector with PBS cube and I am running each with 400mA current (in parallel with 800mW total). I am getting just under half a watt of light output before the dichros and galvos. You think it would it be worth it for me to order two of...

    Laser Shirts For Sale!

    Once you are done with this round of printing/shipping please add my name to a list so you can easily PM me whenever you have a new design. Hopefully this one will by in my possesion by August 19th when I do my next lasershow ;)

    Laser Shirts For Sale!

    I actually wanted one of the XL Tee's and not a Polo. If the GITD is printed in yellow (but also glows in the dark) I will just take that instead. For some reason I though the GITD print could not be seen unless the lights were off... DUH! By the way, I personally think the Tee design looks...

    Laser Shirts For Sale!

    I would like to order one XL of the black shirts with yellow print "remaining eye" t-shirts. I am in Miami Florida, how much and do you accept Google checkout? My damn paypal was frozen so I could just send a money order instead. PS - What does GITD stand for?

    637 nm Red Guidesman - 201mW Build

    Thanks Mr. rhd! Here is the shopping cart link I found: Opnext HL63133DG So they are $176.47 each - I may wait until they drop in price a bit before I order 2 of them ;)

    637 nm Red Guidesman - 201mW Build

    Where did you purchase this ~638nm red diode and for how much? I would like to get a couple to replace the two 660nm red diodes in my RRGB laser projector which use a PBS cube to combine the beams. Thanks in advance!

    Can anyone recommend me a good <1mW red laser?

    LOL - Oops!

    NEVERMIND - WRONG THREAD! Where did you purchase this ~638nm red diode and for how much? I would like to get a couple to replace the two 660nm red diodes in my RRGB laser projector which use a PBS cube to combine the beams.

    Finished my RRGB laser projector - PHOTOS!

    I switched my order from 6 of the 500mW's to instead 2 of the 200mW's and 5 of the 500mW's. I will let you know if the divergence is any different between the two...

    500mW 638nm High Power red laser diode?!?

    Because I am sure there is only one company making 500mW 638's ;)

    Finished my RRGB laser projector - PHOTOS!

    Altogether it cost me about $1000 minus the software/controll which cost $600 from Pangolin. I used decent 30kpps (at 20 degrees) galvos and those alone cost $300. Please let me know if you notice if the divergence is better/worse bettween the 500/200/120 versions. If the 638's don't work out I...

    500mW 638nm High Power red laser diode?!?

    I just ordered SIX of them for $155 with shipping, one of them I plan to test to the maximum using my new LaserBee light power meter :) Here is the datasheet I uploaded to my website for these new "ML520G72" diodes: http://www.zimmtech.com/ML520G72.pdf

    500mW 638nm High Power red laser diode?!?

    Hello, I have been hearing about the new 638nm red laser diodes and I found a seller that has a 500mW version for $25: 638nm laser | eBay NEW 500mW 638nm High Power red laser diode good quality | eBay I plan on using two of them (going to buy six in total) with PBS cubes for use inside two...

    Finished my RRGB laser projector - PHOTOS!

    WOW! Half a watt of red for only $25, I just ordered 6 of them for use in two more laser projectors I am building. I also have a LaserBee USB light power meter on the way so I will make measurements.

    Finished my RRGB laser projector - PHOTOS!

    The camera I used for my other videos did not capture the red all that well. My girlfriend just bought a kick-ass camera so of course I have to test it out. I wish I could get my hands on some 620-640mW laser diodes that put out a decent amount of power. Anyone knows where I might find some...

    Need LPM with USB Computer Connection

    Hello, I am looking for a decent yet reasonably priced LPM (Light Power Meter) with software that is able to connect to my computer. I need a way to professionally document the light output of lasers over time. I was originally thinking about just purchasing a $100 LPM from Radiant Electronics -...
