Kevin's Jarduino Build
« on: January 18, 2013, 12:43:17 AM »
Well......  I've been lurking here long enough so here is my first post. 

First of all a huge thank you to Jamie for all of the work he has put into the Jarduino code and for making it available to us all.

I have had great fun getting my project to the stage it's at now and I'm sure all of you fellow Jarduino'ers will agree that your project can become rather time consuming!!!!  Researching and locating parts.....trawling ebay........waiting for the postie.......bumping off work early to do some more soldering......kidding yourself you can do it cheaply.....anyway.....  here's what I've got.

The box with the arduino, PSU, alarm, DC–DC converters, Relays, drivers and fuses is finished.  I wanted to make mine modular, so that if I ever change my 90litre nano tank all I need to do is change the hood i.e. the LEDs and fans.

Great build, how do you find the fan noise from the psu, i modded mine with a simple temp sensor running the cooling fans, thought it was better off been on around 25% and ramp up with the heat then on 100% only when hot lol

Great work, nice and clean. You are right about time consuming , but I think is all the expectation that hook us when we build it. And we all know is no good to do the math, 5 bucks here, few more there, but no good to sum all. It's the fun and pride to build it, my wife calls it "big boys toy" :)
 How many LEDs / channel do you use with ledsee driver.? I need to drive 8/channel for my next build but didn't have time to test it yet.

Total number of LEDs:

14 x White
14 x Royal Blue
3 x 1 watt Blue for Moonlights
3 x UV (Mainly for an experiment)
I bought red but decided against fitting after reading about algae growth.

I'm going to double up the PWM for both Royal Blue and Whites running 7 x Cree Xp-g per channel running through a 1 ohm ballast resistor and an 800mA fuse on the ledsee.  This leaves 2 channels unused, my PSU is set to 25.2 volts.

The smaller drivers are for the 2 strings of Blue and UV.  These are run through a dc-dc dropper to be fed with a voltage of 10.2 volts.

Great build, how do you find the fan noise from the psu, i modded mine with a simple temp sensor running the cooling fans, thought it was better off been on around 25% and ramp up with the heat then on 100% only when hot lol

Fan noise not too bad from PSU.  If it starts to annoy me I'm going to change the fan inside the PSU for a PWM controlled one and use the unused sump temp probe to control it.

Your dc-dc converters do they go direct to the leds or via led driver ?

Nearly all parts came from various ebay vendors with the LEDs coming from an contact in Hong Kong.  Pics of hood and LEDs to follow once complete!

Via a driver otherwise there would be no current regulation.

Thats what i was thinking you did, dont need the dc-dc converters as long as the leds max amperage doesn't exceed the voltage will fall in line, i have 35v going in to the sure electronic drivers, the 3w one is rated around 800ma got 4 x 3w red leds on it rated at 850ma and around 2.2-2.5v each so max voltage will be 10v at 850ma, as the driver will not let the led go past 800ma its fine, ohms law as the amperage is taken care of as well as the leds fixed resistance then the voltage will just fall in line

Ahh.  I'd read about connecting the smaller strings of LEDs up to the full voltage but wasn't brave enough to do it.  I understand how it works, but it doesn't seem right connecting 3 LEDs in series up to 25 volts - even when they're through the driver.  I had the small drivers and a spare dc-dc dropper "in stock" anyway so nothing lost.  I suppose I have 2 spare channels if I choose to add more LEDs at a later date.

Dont blame you, got 3 x 5w uv leds £7 each but there around 5v each got them on a 3w driver and 35v in, will check the voltage one day lol

Update.  I think(!) I'm finished.  The LED's have been in use for a week now with everything in the tank enjoying the extra light.  I have halved Jamies stock LED settings as a starting point and may build them up slightly week on week. 

My Zoas and Mushrooms are larger than ever, and a visit to my LFS yesterday added a Trumpet Coral and a small Yellow Torch Coral.  I only have one fish - my 16 year old clown fish.  I've had him since he was a tiddler, he used to stay at my folks in my three foot tank until I got organised enough break that set-up and move him to my place.

My existing tank is a second-hand Betta Lifespace 90 litre.  When I bought it it came with a spare hood - I think the previous owner had had a replacement under warranty for some reason.  Anyway the physical parts of the spare hood were perfect which gave me plenty of time to mod it before doing a straight swap with the fitted stock hood with the two small fluorescents and 3 moonlights.

Only one item is puzzling me just now.  The temp sensors periodically flash error which stops and then starts the fans for a second or two.  All three of the sensors do it and in no specific order.  This is a new fault it didn't do it until I put the hood on the tank!  I've checked all of the connections on my D-sub connectors and they seem to be fine.  It may be salt ingress into the water temp sensor or possibly a bad joint to the probes.  I'll check tonight.

As the heatsink is enclosed using the stock fans on the hood resulted in very high heat sink temps.  I remedied this by buying a 50mm blower fan and making a duct to underneath the heatsink.  I duct taped any small holes around the heatsink base making a complete seal which in turn pressurised the whole back side of the heatsink.  I put a super quiet computer fan on the other side as an exhaust.  The heatsink now stays at around 29 celsius which I think is pretty reasonable - with a cushion for a bit more heat when I ramp up the LEDs.

nice one braecottage looks very good what LEds did you use and how many of each
You have to be pleased with that looks very good
I have a boyu tl450 plan to use as a frag tank / quarantine once i empty it simlure sort of thing
Looks Good
