Led curtain

[daztats]

Hi Folks

Planing no making one of them LED curtains (example http://www.djmusiconthemove.com/db5/00481/djmusiconthemove.com/_uimages/ledcurtain001.jpg)

This is my first real project and need abit of help

Firstly how many white leds could i run from a 12v adapter (was hoping for around 45-50 but think i might be dreaming on 12v), I not confident to try out full mains just yet

Thought about using fairly lights but bulbs are to weak and only last 5mins

Also would i need any Resistors Diode's etc etc,

Anyhelp would be gr8 ^^

When thinking about how many LEDs you can run off a power supply, you need to take into consideration the voltage out of the supply and how much current it can handle (usually in mA).

This is what I would do:

If you're using a 1000mA 12V walwart, you can get well over your 50 LEDs. White LEDs pull about 20mA to work well, red and blue need less current. That would be about 3 in series plus about 60 ohm resister. The 3 in series pulls 20mA so you can put 50 string of the 3 in series in parallel with one another, That's 150 total.
