  • Practical Guide to LEDs 3 - Switching & Dimming

    When you get to chapter 5, would you be able to do as an example, the power requirements to run the 5050 LED strip if we wanted to light the eves of say a 2000 square foot house, which would be 61 meters? In this scenario I think we would need to take into consideration the maximum current the base material the led's are mounted on can carry, and voltage drop on the length of the strip. To compensate one would either need to run heavy bus wire parallel to the strip, or use multiple power supplies connected to the house mains wiring. Multiple power supplies are probably cheaper than the copper to carry the DC voltage, so one would likely run a lighter gauge of copper to carry the AC to the various power supplies.This is also of great interest as I am going to be using led grow lights i...see more »When you get to chapter 5, would you be able to do as an example, the power requirements to run the 5050 LED strip if we wanted to light the eves of say a 2000 square foot house, which would be 61 meters?

My plan for the moment is to use an ATX power supply to drive them, but I haven't even gotten that far yet.

    The Herb Hive

    Rather than cutting the half-circle out for the bottoms, put in a solid piece to hold up the pots, and drill a largish hole in the front piece of each module that would let the excess water drain into the next pot down. Depending on potting soil composition it might even be possible to automate watering from the top tiers, with trickle down flow keeping them all happy.Awesome build! If I had the mats laying about, I'd be building one already!
