You think I have time to be your link slave???

Just kidding, here are all the links from under the youtube video. Also will be useful for the future if this video ever goes down:

(FWIW I didn't manually place the > in each row, I did a regex replace in TextMate for: replace ^ (start of line) with >.)

I originally bought the 3A power supply mentioned below by docwhiz, but my atomic pi would boot, run for a while, and then reboot once anything attempted to use the GPU.

In this document they say that you want to have at least 3.5A if you're using any USB peripherals. I was using a USB wireless keyboard dongle when I had these problems, but I was planning to hook up an external USB drive too.

So, I wound up buying this 8A power supply for $16. My api is now happily running even with a 2TB external drive powered from the USB port. This power supply also comes with a barrel connector, which is handy if you're planning to make your own power connector rather than buying the mini breakout board (or the breakout board isn't available, as was the case when I purchased my api).

Why doesn’t anyone use breadboard (Arduino) wires, 3 red and 3 black and put them in a barrel jack that has screw headers? It should be easy to find a high current 5v power supply with a barrel jack.

power supply for reference

Or you could power the strips isolated from each other with smaller supplies like this. (You could still control them with the same data wire)

I would say just buy a switching power supply off the internet for around $15 or less. They usually have all the protection built in and are easy to use.

Here’s a 5V 8A one but you could easily do with 6A.

This. I figured if each servo is drawing a max of 1A, then 8A should be enough

I use a 5V 8A brick with a USB adapter.

How would this work out?
