what you need
1. an ebay account
2. soldering stuff(soldering iron, solder[just about any works], and a wet sponge[one made for soldering(regular ones melt and stink up the place)])
3. Patience
4. a hacksaw(preferably one with a hanging blade[kobalt mabe])
5. a prototype PCB board(i'll show you what it is in update)
6. power supply
7. acrylic resin (you don't need it but it comes in handy) (you can buy it at walmart in the floral section where it's called acrylic water)
8. aluminum foil or a small plastic container heavily lubricated with petroleum jelly
9. a power supply(and all that it needs)
10. other stuff...
step 1
get a power supply

pretty simple if you know electronics

you can use batteries of you want, LEDs consume so little power 20 of them will last months on 2 D cells

pics of mine are coming soon

you can make your own using an old computer's http://www.wikihow.com/Convert-a-Computer-ATX-Power-Supply-to-a-Lab-Power-Supply
connect it to the orange wire

step 2
get some LEDs

this is the easiest part

you get some LEDs

to get cheaper ones go onto ebay I prefer sureelectronics
thats who I got my LEDs from....:devil:

LOL i still don't know wy I do that...

STEP 3 (sorry caps was on but I'm keeping it)
making the LED element:grinyes:

this is hard, it took me 5 hours(less than that I'm exaggerating)

get the prototype PCB & solder the LEDs to it in a parallel way (isn't this standard california curriculum?)

mix some of the acrylic water in a disposable cup

(the pics should explain all the rest[they come tomorrow])


step 4
mounting the LED thingy

I haven't done this yet so...

I'll do it on Friday

What is the color spectrum and light output of the LEDs? This sounds like a fun project if all you want is cool lighting over a non-planted tank but I have yet to see affordable LED lighting that will support plant growth.

Q
That's because LEDs emit on one wavelength (for the most part) so you have the peak wavelength and very little other wavelengths contributing. Which for plant growth are very important.

Q
Yeah good for adding moonlights. And yeah the closest thing to affordable LED lighting is the solaris systems, and a typical 48" fixture is $2800.

LED lighting is very tough to get right.



First thing i've found: DO NOT shop on ebay.

"ebay" LEDs are very shoddy quality and rarely match the wavelength and/or intensity specified in the advertisements.


I'd only buy high-quality LEDs and high-quality constant amperage and voltage transformers.

here are the pics

heres the power supply...



here's soldering station



I'm sorry I couldn't get the LEDs themselves... but I'll get em...

here it is, and with a lil comparison and yes the spectrum is a lil cruddy... and the glad thing is so it wouldn't spill... and stuff...
