    New Laser Build for Night Vision

    You are right. With a $20 USB video cable device one can run the IR camera feed directly into a laptop instead of the monitor. Sabrent USB 2.0 Video/Audio Capture DVD Maker Adapter - USB 2.0, MPEG Encoder, Plug-n-Play at TigerDirect.com Good idea!

    New Laser Build for Night Vision

    Good points, you know what you are talking about. Let me respond, as I have thought about this too: -Scope light transferance loss: You have a point as there will be light loss. Though my scope is excellent, a Nikon Monarch 4x16-50mm. I can see better in the dusk thru it than with my natural...

    New Laser Build for Night Vision

    Yes I plan to mount the camera behind my 50mm scope on a Rem700 .243. What drawbacks do you see? There is a necessary trade off for the economy of the build!

    12V Buck Driver question

    I think I figured out a cheap solution. I will cannibalize a simple 12vDC car charger device outputting 5V at 320mA and run it in line from my power source. $6 Amazon.

    New Laser Build for Night Vision

    Jaybeez Roland of "Rolaid's Bench" the author of the youtube video you linked actually answered that question for me on his youtube channel. He said, I have used it with 808/850/915/940 and the camera does well with all. That being said as you move up the 'scale' the sensitivity of the Sony...

    12V Buck Driver question

    I have a 12V power source and want to run a simple 808nm 300mW laser module at its driver's operating voltage of 3-5V and 320mA of current. I want to run my laser in the field off of the same power source that I will be running my other electronic equipment, which is a 12 volt 7Ah lead acid...

    Effect of Plano-Concave lens in standard focusable dot laser

    Steve, Thanks for posting. I need to clarify for you that I am considering two (2) options. The first is leaving the original lens in (collimating lens), which I am now guessing will crossover at a meter or two and then began expanding at the original lens divergence of .5mRad. And this answers...

    Effect of Plano-Concave lens in standard focusable dot laser

    My goal is to expand the beam to illuminate objects in the night. A "laser pointer" will not serve my needs at all. I am inquiring as to what the beam will do with this plano-concave lens of -8.111 focal length. As I have thought more about what the original lens will do to the beam after...

    Effect of Plano-Concave lens in standard focusable dot laser

    Question from a newbie. Anyone have an educated guess what kind of beam divergence I might get by replacing a standard collimating lens (~.5mRad) in a common dot focusable laser module (808nm 500mW) with a 6mm plano-concave lens (-8.111mm focal length) with the module having an original beam...

    New Laser Build for Night Vision

    I'm a newb and glad to be on the forum. Am trying to put together a relatively high powered focusable Laser illuminator good to 300+yds for the economy and fun of it all. I just bought and am waiting to receive an infrared EJ230 bullet camera from Kt&C and the specs indicate that its SONY 960H...

    Hello from South Texas

    I got interested in joining while researching for a laser illuminator build I am doing for night vision hunting over hogs here in South Texas. Pleased to be here.
