Introduction: Infrared Night Vision Camera for $15
This is my first instructable and I'm 13 so be kind! Ok, so i wanted to make a cheap DIY night vision camera for cheap and I watched a couple of videos on how to do it on a cell phone, then made it with my camera. It uses infrared light from the LEDs which is part of the light spectrum that our eyes can't see, but the camera will pick it up as light and illuminate the camera screen after you take out the IR (infrared) filter. HERE WE GO!
Step 1: Gathering Tools and Materials
Materials: camera (digital, I got mine for $10 at my local pawn shop), infrared LED I used 6(I found mine online at a robotics shop. Your local robotics/ electronics shop will most likely sell them), resistor( my LEDs work best with 390ohm, these will vary), 9 volt or other battery pack, snap clip ( if using 9 volt), switch( optional, I didn't use one). Now the tools: hot glue gun, solder iron and solder, screw drivers, needle nose pliers (optional). That about sums it up!
Step 2: Opening the Camera
Now to remove the filter we need to tear through the camera, taking careful pictures so we can put it back together. When you start, there might be some hidden screws on the camera, so make sure to lift up any stickers and look under rubber protectors for ports.
Step 3: Removing the Mother Board
To remove the mother board so we can reach the IR filter, we need to take out 5 or 6 screws. Be careful because some of the screws in the camera may vary by legnth.
Step 4: Removing the IR Filter
Now is the delicate part. Removing the camera IR filter module and taking the tiny piece of glass out. The glass will be in a gasket on the back of the housing. You can pry it out easily with a flat headTake your time. Don't get dust on the exposed camera exposure chip. The IR filter will be about .5cm in diameter and will be most likely square.
Step 5: Putting the Camera Back Together
Just place everything back the way you took it out. Then we can move on. Once you put it back together and turn it on, it should see in a odd black and white ish color
Step 6: Assembling the IR LEDs
I assembled mine in series circuit, but you can do parallel. I used series so it can fit around the round lens nicely. I assembled them twisting the legs, then soldered.
Step 7: Using the Camera
Here I am in my bathroom (darkest room in my house) using my camera with 11 LEDs (improved version) in the dark. The first picture is in the mirror to show the illumination of the LEDs. These aren't the best pictures, but they work!
Step 8: Final Product
This is what my final product it can see about 1 foot in front, but I added 5 more LEDs and it sees 3 feet in front of it, the second photo is the improved version with 11 LEDs. Now it's your turn! Good luck!
