Nano Smart Aquarium

 
#1

Ok this is the second project where EZB will be used to control lighting , current flow , temp , salinity ect. This thread will show just about every step ot the build , electronics , wiring and eventually the scripts to make it work. Winky - Josh Starnes

A nano aquarium is 30 gallons or smaller , in my case its a 10 gallon. These are considered very difficult to manage because due to the size they are more sensitive.

So the pump is in and functional , biopellets and carbon reactors are running now

So I added about 10 pounds of live sand which causes a large murky cloud. The ezb is already ordered for this one so I will start making everything. Next step is excellent lighting in both actinic and warm daylight.

Here are the leds I planned on using , both a bright and warm 10 watt led and a blue actinic 10 watt.

Because these are very high power they need a heatsink and maybe a fan. I believe they run on 11 volts. Here is the case that is a old cable modem which could look good as a project box either for ezb or the lights themselves.

Ok so the three 10 watt leds produce tons of heat and a heatsink is a must , I tore apart an old power supply for the large aluminum heat sink plates. After cleaning off any corrosion and thermal paste I used ca glue on th edges of each led. I used brass standoffs and drilled mounting holes so it can be taken apart at any time. The cable modem case I gutted has a nice pattern of small holes as seenn n previous pictures. I picked out a drill bit double the size and widened every hole in the case and also added 4 more rows by hand in the same pattern. It turned out great like it was suposed to look that way. I also used a 5mm bit to drill out holes in the bottom to mount leds. Both blue leds for night light and uv/purple for dusk and dawn. I cut a window off the bottom and added in a 40mm slim vga 12v fan to help keep air moving past the large heatsink. Because we didn't have a good 12v 5amp or higher regulated supply we hsd to stop the project for tonight. I was really hoping to have a light on tonight :/ its ok though they ae by a window. So they will have some light anyways. The case I gutted for the. Heatsink is going to house the ezb and the switching transistors to turn each led on and off , the actinic 10w , bright white 10w , warm daylight 10w , 5mm led blue , and 5mm uv/purple. So I sm repurposing the case. The 60mm fan will cool everything and I will probably paint it black as well.

Im trying to hunt down a used pc power supply I can use to power ezb and these monster leds. The two extras i had were both cooked. I need at least 50 watts RMS for the leds and ezb. I emailed some one on craigslist , im crossing my fingers that he hooks me up. Otherwise I will either need to buy a 5 amp power supply or buy a pc power supply for like 40 dollars just to modify for power. Hmmm

I am not fond of failures but sometimes they happen. I wired the high power leds and they looked great.

You can see the 40mm fan in the top of the case. In testing it worked but failed a few minutes after powering the lights o . After a while I noticed the color started rapidly changing and poof of magic smoke started escaping , I took. A deep breath and looked inside. The first thing I noticed was the fan was not spinning. Without airflow in the case the leds eventually overheated. While the fan was working I did take some pictures though

Without light most the fish just huddled behind the pump. They were not brave enough to explore the rocks in the dark. So anyways I was bummed out but it happens , cant get everything right! Lol - Josh Starnes

#9

where did you get the leds from

#10

I purchased them on ebay , search 10w led. When I do this again I will use a much larger heat sink.
