    6x 405nm diodes FS

    Sorry, I meant just for the three SF-AW210, can't use the 3.6mm's:) If you're interested, please PM me and we'll talk details and price.

    Cheap LOC build

    Very lucky, considering how good the fit is. OD=1", I bought 5 of these from Mohrenberg, then it was a matter of checking every flashlight everywhere I went - spent a lot of time at Target, for example...:)

    Another Breakthrough at CERN

    Someone smart please comment on the following statement: there is no such thing as an anti-photon. My reasoning is that anti-matter produces light that is indistinguishable from light produced by regular matter. Here is another way of saying this: if some very far away star made out of...

    Cheap LOC build

    Thanx Jander! I liked your PHR build you did in this host. The ring doesn't stay on anymore. I had to use a button from a diff red flashlight, and it's a little smaller diameter, so the ring falls off:)

    Cheap LOC build

    I took pictures side-by-side with my 1st LOC build, also using a glass Aixiz 650 lens. I bought 2 more, and the new ones seem to have more spill. I can make out the shape of the inside of the diode with the 2 pins and the hump in between. Does this mean the back of the new lens is not coated...

    The Scale of the Universe

    Possibly...:whistle: WRT String Theory: isn't it a great satisfaction to think that the basic building block of the Universe is a vibration of a string? Like a song. Sounds very similar The Silmarillion's creation story.

    The Scale of the Universe

    That is because the Universe is the brain of a creature, we might as well call it "God".

    Spectrometer readings of some common diode lasers

    Excellent thread, Sir! Do you have a LOC to try?
  17. comradmax

    if you offer "laser safety" advice please read

    I can only look at my DIY LOC dot from the incident side. I noticed quickly that on the reflected side there is an extremely bright speckle pattern, even from matte surfaces. I would never point a laser in a manner that would get it reflected toward anyone, or any-cat. There is also speckle...

    DIY PHR tripod labby build

    Thanx everyone for their positive comments! I'm glad you liked this little build:) spokanedavid, I'm new to many laser things... By scanner are you talking about a 3D laser scanner for making models? I should look into that, sounds like an actual useful thing to do with these lasers:) Oh...

    DIY Arduino LPM

    I can still solder the OP-amp by hand. That ADC chip would require me to learn a new way of soldering:) P.S. Is thta Half Dome in your avatar? Seeing must have been great at Yosemite. BTW, what is the 3181253 number for your Solar system location?:thinking:
