Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
A 16 USD car dvr is very suitable has a in built battery and USB charging
Hack remove the two items the LCD screen and the battery .
*preferably remove full LCD screen frame and buttons
* stick to just a Acrylic piece with smd LEDs to light it
get longer cables to attach it (tricky)
Take a helmet and try to attach the DVD main unit
* LCD goes into a slide viewer toy
Step 2: The Slide Viewer Screen Unit
The toy has to be trimmed(cut lower plastic) or lenses taken out and fitted in a lightweight plastic box.
Focus the lcd to have a comfortable view an fit in the other side where Slides used to come. Wire the lcd from main unit via some flex wire set
Step 3: Modify the Camera to Get IR and Others
Now remove the IR filter , there are many videos how to do that
Remove the battery and put in a diy battery pack
may be 1200mAH X3 pack via volt dropper circuit to pump 3.6V
or use a diode dropper in series 1n4007 X2 in series this will drop approx 1.2V from 4.5V
As the DVR current is low diodes wont heat up .
Step 4: Add a Cree IR Torch Solder Mountable
IR illuminator Clip glued to it will serve as good invisible light
Needs a 12V supply .
9V rechargeable with booster can be used
Thats it now start your hunting/spying missions
