Although I have some fair experience with electronics, it has all been battery-powered. I know that a transformer can step wall voltage down, but in doing so raises the amperage, correct? I know that the forward current limit on a 555 timer is lower than most wall-wart tranformers supply, and therefore lower than what a power supply can supply? Thanks!

On the front page there is a list with featured Instructables, one with "Zeitgeist", whatever type of German Wurst that may be, and one with Popular. But where is the simple "Most Recent" list. It should be somewhere!

how can i make a nightvision circuit with only an tiny screen and a tiny lens (from an old mobile phone)?
Recently I bought a new cellphone because my old one was wrecked, and old and so on and so on. so I took it apart, and finished with the parts I wanted, a tiny color screen and an tiny lens, with leads to an tiny red thingy where underneath a sort of connection circuit. can anyone give me a schematic where I can see how many power, how to connect, and how to turn on and off the camera. because I want to make a night vision set, which you can make with for example a webcam or that one on your mobile. but I want someone, without any cords, one you can build in an a modified pair of glasses. thanx in advance!

Why does there appear to be banding when I look at pictures of the visual spectrum or light through a prism? Answered
It seems like when I look at one unit of the spectrum the color looks pretty much the same at opposite ends of the unit, but when I look at another unit of the same size at a different place in the spectrum, the color seems to change drastically from one side to the other.
