    If you chose to buy the flashlight instead of make it, what would you do with it, would you just glue it on somewhere?

    Hello Tony,
    I was wondering if you could make a video of you making these DIY night vision goggles, it would be really helpful in helping me create it.

    Hello Tony.
    Great Project! I would like to ask if it’s okay to use an IR filter instead of welding glasses? Will the IR filter give better results? If the answer is yes, which IR filter would you recommend? ( I mean in nm. )
    Thank you.

      Hi Mark. Thanks for contacting me.

      It is a good question.
      But let’s be very clear here…when we talk about infrared filters, we mean PASS-filters. That is to say the filter passes IR, and blocks everything else.
      Now, our eyes cannot see IR. That’s why we use a board-camera in the more advanced project above…to actually see the light after it has been filtered.

      So unfortunately using an IR filter alone will not work.

      More info: Human eyes can only see light in the spectrum, starting around 400 nm to about 750 nm. When we talk about infrared here, we are referring to the light that is “near to our range of vision” and moving higher in the spectrum…specifically 750 nm to 3,000 nm. (aka: near infrared.)

    Great Project.
    But I would like to know, if I buy an infrared flashlight and I make the glasses as the steps you provided in the project with 2 layers of each colored gel…will I be able to see even in total darkness?

      Hi David. Thanks for contacting me.

      If you are going to the expense of purchasing an infrared flashlight…I strongly suggest you consider utilizing the board camera for your homemade night vision device. The overall expense is not much more…and the results will be far more rewarding.

      The project involving the colored gels is really intended to be rudimentary. Results are at best, a simulation of night vision.

    Hello Tony
    Great Project! I want to ask if you have ever tried gluing theatrical gels to a telescopes lenses? What do you think will they work and produce night vision with the help of an IR source?

      Hi Ajmal. Thanks for contacting me.

      Honestly, I have not even thought of that…but I do like the idea. Have you tried it yourself? Please let us know your results.

    What gauge electrical wire did you use on the first one?

      Hi Nate.

      I had some old 14 gauge wire sitting around that I used. Since it is very low powered, you could even use 16 gauge.

    I really loved your article on Make Your Own Night Vision Goggles. I was wondering if you could help me with a project I set up based on your mini spy-cam version. It consists of using a 12 volt spy cam, http://www.esentia.com/product-p/aceex360ehp4.htm and connecting it to a 5 volt LCD mini screen. https://www.sparkfun.com/products/11377
    I need to know how exactly to do this because the screen itself has 9 prongs and will probably need resistors between the connections. If you have any input on how I should go about connecting this spy cam model to this mini Screen, it would be greatly appreciated. Thank you very much. Dan.

      Ive actually switched which model of mini-cam ill be using, though I doubt it will make a difference. Product code ACES360EHP1.

        Hi Dan. Thanks for contacting me.

        My best advice would be to contact the LCD manufacturer http://www.4dsystems.com.au/support/
        Make sure to include info on the board camera.
        BTW: nice LCD.

    Can you please tell me if using welding glass lenses is essential? Will an ordinary glass lens work just as good?

      Hi Soham…and thanks for contacting me.

      Welding glasses are best as they inherently have light filters incorporated into the glass. I haven’t tried for myself, but I suspect ordinary glass lenses would work but you would need much more colored gel.
      Please let us know how your project works for you.

    Hello sir. I can’t find theatrical gel. Can I use blue and red plastic for this propose? And have you other interesting projects? Send it to me with detail. Please reply quickly as possible. THANK YOU.

      Hi Jitendra…and thanks for contacting me.

      Theatrical gel is made of poly-carbonate or polyester plastic…so look for those types of plastic. Let us know how it works out for you.
      Let me mention that the project involving a “board camera” gives very impressive results.
      I’m working on more projects to post.
