Hey two queries:

1. if in a kit being built the operation requires 12v to power and run - i know i can use a 12v battery or a combination of other voltages, but would the battery be drained too quickly (assuming a good long life battery). I have been told when you use batteries to power circuits, like for instance a motion activated light or something, the battery will be drained very quick.

2. i have googled and looked in a lot of places and cant seem to find any reasonable instructions on how to build anything associated with night vision, particulalry a night vision camera to record a night's activity, or just simple night vision goggles or something like that.... any idea?

thanks

A battery is drained by the amount of current used by the load. Anything that gets hot uses a high current.
A heater or electric motor uses a high current. An incandescent light bulb is also a heater.

The IR LEDs on a night camera also use a fairly high current.
