    Default finally testing out my DIY led system

    well its not going to be installed in a tank for a while, im thinking of using them on my 5.5g betta tank when i do it.

    any ways, im using up the 8 spare 1w 6500K leds, just ordered all the parts for the light, might need a extra heatsink material for the leds themselfs but im just testing if my CCC circtuit is working.

    basically im using a mosfet and npn transistor to run the whole thing, a 9v 2a (18W) wall wort for power (reason on that later).

    but the coolest thing i can do with this circuit is dimm it using an arduino, thats why im trying to limit it to 9v. i remember the days of "i wont how we could simulate sun rise/set" well here it is. i wont be able to afford the arduino for some time (specially thanks to me wanted to do CO2 in my 55g) but if the circuit works the way multisim claims it can, i will be able to run all 8 leds without the worry of resistor blow out failures. for some reason this seams a bit less efficient for this project but i guess the closer you come to the voltage drop the more efficient it becomes. 95% would be max for this i think. thats fairly good IMO.

    BTW the leds im using are infact the cheapy fleabay ones, but should do their job for the cost... i might be kicking myself in the rear later but W/E lol
    I wonder if i plant one of my tiger barbs would the demon seed grow to a full tree?
    gotta love them bunnies!
    I.R.S.: We've got what it takes to take what you've got!

    Dimmable LEDs sound pretty cool and the fact that it is a DIY is even cooler. The extent of my knowledge is that when I touch electricity it hurts! I'm still trying to figure out the capacitors on my tattoo machines, lol. With the way you wrote this out, I'm guessing it oughta work like a champ, best wishes!
    When in d0ubt read it until it makes sense, then read it again!
