DIY LED lighting + DIY LED driver + DIY LED Controller

[Jimmy54]

If I had those skills, I would try to make a few extra buck's out of it.
Heeps of people on this part of the globe looking for an affordable LED unit above their tank.
Great DIY project

FWIW.. I just purchased a bunch of 3w 18000K 220lm 3.3 to 3.6v LEDs from a company for a $1.29 which more closely match the performance of the XR-E.

My too, 300 of them.
You probably don't know whether those 60 or 80° lenses from Satistronics will fit on them ?

Thanks in advance.

Well, unfortunately I'm located in another part of world (in Russia) :spin1:

Great DIY project

Thanks. Actually, although the schematic of my controller and drivers may look somewhat complicated, if you have very basic skills and can solder such small parts (it is not very easy but quite possible to do at home with some experience) it should not be too hard to repeat all these devices.

You probably don't know whether those 60 or 80° lenses from Satistronics will fit on them ?

Have no idea, sorry. Lenses from Satistronics are for XRE leds, and to attach them to my XPG and XPE (which are smaller) I glued lenses to led stars with silicone.

From www.ledfedy.com. Email sales@ledfedy.com and ask Ava for the 18000K 3W LEDs.

How do you understand that site?

ANY data sheets on those LED's I know more than a few people who would be interested in seeing them.

Thanks!

Privet, kak dela? Vi gde zivete v Rocie?

 

[skanderson]

very impressive thanks for sharing. still trying to get over the disappointment that you wont be able to make a few of these up for me for the right price.

Try this one

On page 8 you will find the 10.000 - 20.000K leds - have a ball :spin1:
At the bottem of te page you can contact Ava.

Those LEDs look horribly inefficient by today's standards. You would need twice as many to match Cree XR-Es 228lm.

FWIW.. I just purchased a bunch of 3w 18000K 220lm 3.3 to 3.6v LEDs from a company for a $1.29 which more closely match the performance of the XR-E.

Did you also purchase any optics or drivers from that site? If so what was the quality?

I'm using Sprint-Layout 5.0 software to draw PCB, it has export to Gerber feature, but I'm not sure if it works correctly (have no idea how to check generated gerber files...). So, here is zip with PCB in original Sprint-Layout format (*.lay file), two gerber files, and in another zip - some screenshots

Impresiv:beer:! Can you share with us controler PCB layout?

And now the most interesting DIY part – The Led Controller.

2. It is fully programmable via BlueTooth. Sunrise, sunset, changing color temperature and intensity of light during the day and so on – all these things could be programmed via graphic interface – a special software running on PC. Of course the controller operates independently, PC software is used only to change settings and it is not necessary to keep PC turned on whole day

Can yuo share the link to PC software to program controler ???

is their any updates on your awesome rig

Hi there True believer71
I was looking at the whites as well
do you have tried any of them?
do the ones you bought..do they look too blue?
do you suggest to buy the whites?
thanks

Very nice sanamyan! I like the chip for the driver. Will definitely take a look, as I also don't like the PWM from the CATs and the fact that I have to adjust the PSU (though they do work pretty well).

Why didn't you just order a bunch of PCBs from a fab house like seeedstudio and/or iteadstudio? Their prices are so dirt chip at this point, that it doesn't make sense to spend the time to etch your own boards.

Anyway, great job.

Браво!

Is this driver sufficient enough to handle 120AC? Just curious if Russian household outlets are the same output as American.

 

[sanamyan]

We here have 220AC, but it is not matter because the driver is connected to DC power supply (48 Volt DC), so the only difference will be the type of power supply.

 

[slobodan]

sanamyan,

I know this will sound silly but I like those white wires and connectors that you are using in your design and for hell of me I can't find them anywhere.
Can you tell me where you've got them and part # if you have..

 

[sanamyan]

These white wires and connectors are from ebay, for example here: http://www.ebay.com/itm/50-pcs-3-Pi...61?pt=LH_DefaultDomain_15&hash=item43a6d8bf01

 

[slobodan]

Thanks sanamyan.. What is the awg of that wire?? 22awg?
Now if someone can point me where can I find those on sites like www.mouser.com or future or digikey or any other similar site I would pay for it. I spent 2 days trying to find something comparable and that I don't have to buy 100' of it.

Appreciate your help..

 

[slobodan]

Sanamyan, I'm looking at your schematic for driver and you are applying 0-10V PWM signal to Iadj??
As per datasheet Iadj pin takes 0-1.24V to do analog current dimming. Am I missing something?
I'm going to do external shunt dimming but just curious about your approach.

The Led Controller

The Led Controller

Dear Sanamyan,

I saw your DIY Led lighting of your reef tank and it is very cool. Now I am thinking that to build a same one like yours. The technical datasheets are very detailed and good explaining how to build the hardware of the lighting, but not much information about the software. Could you please share with me (or with Us) the computer software and the controller code also.

Thank you for your help.

Regards hollo80

Dear Sanamyan,

It is very interested project and smart idea. I am considering to have the same like yours.
Could you please share source code and HEX file too?

Best Regards,
Hams

Old diy build Bluetooth module

These white wires and connectors are from ebay, for example here: http://www.ebay.com/itm/50-pcs-3-Pi...61?pt=LH_DefaultDomain_15&hash=item43a6d8bf01

Sorry if broke a rule orsomething because this is an old diy led build but i woud like to make the Bluetooth module for my tank and because im only a hardware kind of guy i dont know how to build the software necesary. If you could share how or your files i could probably figure out myselft i just dont know how to start from scratch. Im sure other people will apreciate it as well

Thanks
