What do RGB LED Signal Amps consist of? Answered

Im sure this is a little bit of a noob question, but i was wondering what rgb amps are made of, and if it were possible to make one for cheaper than the ones that you can buy? the amps that i am speaking of are like this i dont really know what kind of response ill get from this, but any information on any thing or any better amps would be wonderful!

the amps like that are made up of the following

the input leads are connected to a diode and resistor then an opto-coupler on the output side of the opto-coupler there is a transistor that feeds a mofset the input and output are isolated by the opto-coupler. the new power is fed into the output side and goes threw the mofsets to the output pins
the above circuits are repeated 3 times (one for each RGB channel)

you cold build one less complicated but the parts could cost about $15 and you can buy them pre made and packaged for $25 so i don't know that it would be worth it

I believe they're devices which can be plugged into the output of an RGB LED controller in order to power another string of lights. Theoretically, that's just a set of unity amplifiers with high input impedence and output drivers which can provide enough current to run a sufficient number of LEDs to be interesting.

I'm presuming you've already looked at the Instructables in the "Related" column at right; there are several RGB LED projects listed there.
