jnam Posted February 18, 2011 Share Posted February 18, 2011 I bought me some steves leds and his single driver to give it a go. This is a single string of 4 LEDS @ 700mA and dimmable. The control box has the driver and fan and ATO built into it. LED Light 4 x 3W emmitors from StevesLeds 1 x 700 mA dimmable driver from StevesLeds w/ pot for dimming 19V laptop power supply @ 3.2A heatsink and Fan combo for a processor Some wire and switches and some stanard LEDs the base and legs off of a picotope light 9V @ 500mA wallwart for fans and ATO the fan off of an old video card I tried to gut the pictotope light and find a heatsink for it but with a fan it just looked hokey and i didnt like the look at all. ATO White outlet square 9V relay NPN power transistor (i can read the package lol build it out of the junk box) project box. NOW FOR PICTURES The pile of things i started with The modified picotope light The begining of the soldering for the main board All the insides where they go 90% finished control box Assembled ITS ALIVE!!!! Completed control box (the knob on the pot was extra long) The finished light It has an audio jack where the ATO float plugs in that sthe whate cable. Masterfull soldering About 50% bright on tank at full brightness thats it folks Link to comment
Flicker Posted February 18, 2011 Share Posted February 18, 2011 Applause!! What is the estimated cost for this project? Link to comment
herranton Posted February 18, 2011 Share Posted February 18, 2011 Looks Good. A couple of questions, How does/will the ATO work? Do you have a picture of it on the tank but with the LEDs off? Link to comment
jnam Posted February 19, 2011 Author Share Posted February 19, 2011 The ATO is just a relay controlled by the float switch. The relay switches the 110 for an air pump the air pump force the water into the tank. Lights of pic comming right up. LEDS and Driver 30$ fans heatsink and walwart 15$ Laptop power supply 10$ Random radioshack crap 25$ 80$ total probably more because it wasnt about cost rather just for the fun of the DIY Link to comment
andru24 Posted February 19, 2011 Share Posted February 19, 2011 Cool. What color are the LEDs and are they all the same? Link to comment
jnam Posted February 19, 2011 Author Share Posted February 19, 2011 the are actually 8500K I am doing a planted freshwater tank but because the picotope is a common pico reef (it was one for me up until we moved) I thought an LED build for the stock light would be suited here. I did originaly plan to do it as a reef but the boss said no... ON that note The original set up called for two driver for seperate channel dimming and 5 not 4 LEDs for blending Link to comment
