I'm not sure a video counts as an Instructable...
Is it only me, Or did you wire up the schematic incorrectly? Isn't it supposed to be positive to negative to positive?

If it turns on with fire, Won't it also turn on with sunlight?

:D if you have a little bit experience in physic for sure you know frequency of light , infrared is light too the device only works with high frequency of infrared light

The sun emits IR light too, That's how we feel that sunlight is warm...

An Instructable has to be "Step-By-Step"

You can ask the staff if you need help with that, Or you can also search in the Instructables search bar "How to make an Instructable"
