I'm modifying an IKEA Ramvik coffee table by mounting lengths of individually addressable RGB LED strip under the glass controlled by a Raspberry Pi. The LED strip is pretty standard; running at 5v with 32 RGB LEDs per meter, each one has an WS2801 which talk to each other via SPI. It's identical to this one: https://www.sparkfun.com/products/11272
In total there's going to be just under 17m of strip: 16 rows split into 106cm sections. I'm going to be wiring the rows up snake style and dual feeding to keep brightness consistent across the array.
At full brightness, with all LEDs on, each row of strip will draw just under 2 amps, multiplied by my 16 rows, that's 32 amps in total. With this much ampage running I'm concerned I'm going to need some hefty wires to handle the load without dropping voltage. Unfortunately the design of the table means that there's only around 3mm space underneath the glass so the diameter of the wire is important.
The 5v power supply is going to be mounted inside the table, around 0.5m from the start of the LED strips. I've been running some calculations which says even if I use 16awg wire I'm still going to see a drop of ~0.5v.
Is there any way I can negate this or do something to prevent it?
