My moonlight project

I took some scrap acrylic, some 10mm blue LED's, and some chrome plastic holders and came up with 8 of these. I'm going to try to get them mounted & wired if not wed. then this weekend.
 
cool project. You may want to eliminate the screw in a sw tank or they might look rusty pretty quick. I have a extra moon light laying around I might mess some acrylic as I had not even thought of using it but your mount makes it look easy.

Let see what it looks like done :D
 
use stailess steel screws then the wont rust if you can get them. I get mine at work but i'd imbed nylon nuts in my canopy then finish over them with filler. I have a peice of plexiglass in the top of my canopy which is threaded were i put my mounting screws. BTW i think the chrome finish will rust as well and will also flake off.

If you're talking about the holders I don't think it's actual chrome. They're plastic so it's probably more like paint.

Got them mounted to the canopy. Here's a pic.

Well, got them mounted, wired, and canopy back on the tank. Now I need to hunt up a power supply.
I know I need 12 volts. What I don't know for sure is what I need as far as amps. The LED's w/resistor are rated for 20-30 mA. Now, since there are 8 hooked in paralell am I correct in assuming I need 8 x 20-30 mA for a total of 160-240 mA?

Yep! Your math is correct....just make sure you fuse the power supply and I'd suggest 1/2 amp fuse. You could power the whole thing off a 12vdc 1amp wall wart from radio shack, and buy an inline fuse holder for it....

Why not an old computer power supply :wink:

Yep, that would work! Just any 12vdc source will work.

I usually have various wall warts lying around for projects but never have a non-used computer supply...hehe :lol:
 
I've got a ton of both, but a full PC power supply would be a wee bit of overkill to power 8 LED's in my humble opinion...
 
Main reason for the wall wart is to be small & fit my DC-8 without crowding out another plug. I do have an old PC power supply but I already went and got a wall wart from Radio Shack. Didn't have a 12v wart laying around. Everything but 12v but no 12v.
 
Well, 10:30pm lights went off, moons came on. WOOHOO, they work!
Now just need to figure out how to make my camera take a pic.
