DIY leds...now with arduino Controlled lights...
first from the beginning...
I was of course endoctrinated by this 2 guys... Soundwave and Santoki... So I gain courage and bought: 2 large aluminum heatsinks several pc heat fun 36 XR-e Cree royal blue 42 XP-g Cree white 12x 700 mA bucks with pwm control (more on that later) the bucks have 7 leds in serie in case of xp-g and 6 in the case of theh XR-e power supply of 24 Volts with 10 Amps... An Arduino clone diecemilia, with 1 lcd shield for that. (used for "robotic" projects.... with some pins capable of pwm control) lenses only for the larger aperture XP-g, of 45ş. artic silver glue compound (I attached the pcb of the leds with that glue) I even soldered the XR-e emitter with some star pcb I got, very nasty job, but better than in the factory, I can manage less distance between the leds and the pcb, for the xp-g I think because of the size, I couldn't do it... at full strengh I got something in the vicinity of 175 watts. for my tank 120x60x60 cms The arduino code is still improving, but some of the features I want, I already was able to do...when I press the on button the light went to a increase status, only after 15 minutes I get the full power... moonlight (with only the XR-e royal blue) my camera cannot save the fluorescences... No more talk here is the image and the videos Sorry about my lausy english... playing with pwm and thte arduino: http://waterinspiration.blogspot.com...m-e-com-o.html one image with the tank lightened with the leds... http://4.bp.blogspot.com/_aZd4u6ysNS...0/100_1021.JPG See the arduino at working... the fluorescence is magnific, I wonder why my camera cannot see that... maybe too much blue. http://www.youtube.com/watch?v=G3hvG...layer_embedded some of the work: http://2.bp.blogspot.com/_aZd4u6ysNS...0/100_1011.JPG Regards from Portugal... |

I didn't documented the work in progress, sorry... but it was like Santoki project:
http://www.reefcentral.com/forums/sh...readid=1587273 the biggest difference, was using XP-g for the whites instead, and XR-E for the royal blues, both with 700 mA bucks... another big difference, was the type of the bucks, I used this ones instead: http://www.led-tech.de/en/LED-Contro...2_118_119.html it has the pwm capability that i wanted, it operates reversed, so they don't claim compatibility, but it does work. at 0 it does max light, with 255 no light at all... (with the arduino) http://www.arduino.cc/ it as some pins that are capable of pwm, not all... but programming this is simple... If you want I even could put my code in here... but it's kind of big. I can send to anyone the code... I connected the grounds of the arduino and the power supply, the pwm capable pin to the + pwm in the bucket... and that is it... |
