Automatic, Biorhythm LED Aquarium Light

Step 3 Installing the main wiring

So the main idea here is to mount two lengths of the braided stainless steel picture hanging wire parallel to each other. One will be positive, one negative. The LEDs will be strung between, allowing you to add more LEDs if you want more light.

I got four threaded aluminum posts with matching screws from Lowes for under a dollar each. Your mileage may vary, but they shouldn't be expensive at all. Mine are 3/8" long to allow for some space when installed.

That space comes into play when preparing the cable. You'll want to wrap it around the post for about 2 wraps, then pull out the post, keeping the loop in the cable. You can see it below in one of the clips of my helping hands. I soldered the wire to keep it solid. Since there will be tension applied to it, make sure your method is just as stable.

Getting one end done is a cinch, but the other side takes a bit of skill. You want to install the cable on one end, and then the remaining post on the other side. Now, wrap the loose cable end around the empty post, trying to keep enough tension. You want each cable to be fairly tight between each end.
