Introduction: Night Vision
In this instructable i will show you how to create night vision goggles using the arduino kit and a few other componets you have laying around the house.
Step 1: Find a Digital Camera
For this step pretty much any digital camera will work. Depending on what kind of camera it is will determine the steps it takes to get to the IR filter. if you use a camera like the one in the picture you will not need to do what i did for a power sluppy. I simply took a headlamp apart and used the dual AA box to power my camera.
Step 2: Remove Contents From Housing.
to make a digital camera able to see infrared you will need to do the following to your device.
1. take housing apart thats surrounding the board and lcd monitor.
2.carefully remove the ribbon bands connecting the lcd screen.
3. under the lcd screen you will find the view finder. There will be some small screws to remove the cap covering the view finder.
4. once its off you will see a small square film. usually red in color. carefully take a knife or tweezers and remove it from the glass. once that is off you can repeat the steps in reverse order and the camera will be able to pick up IR light.
Step 3: Wire Up the IR Leds
1. for this you will need Infrared leds. Depending on how many you use will determine how much you can see in the dark.
2. i am using 6 940nm IR leds
3. first start by connecting a 220 ohm resistor to the positive lead of the LED. do that for all 6 leds.
4. after that connect a ground wire from the negative lead and solder all 6 together in one big wire.
5. connect the the grounds to the ground port on the arduino.
6. With each positive lead connect it to the port 7-12.
Step 4: Wire in the Button
1. for this you will need a intermittent button and 3 wires.
2. first start off by soldering a 220 ohm resistor to one of the 4 prongs on the button. (this will be your positive side)
3. for the remote side solder a yellow wire across from the negative side.
4. solder a ground wire to the ground side.
5. after that hook up all your wires. ground to ground on the arduino. positive to the 5v port and the remote side will go to the port numbered 13.
Step 5: Put It All Together
last step is assembly, i used a vcr tape box to hold the arduino. using alot of electrical tape i was able to put the camera against the box along with the bulbs without any interference on the screen. A project box would have been a better option for this. Each night vision set up will look different because of the cameras shape.
