I'm planning to control about 150 WS2812b LEDs with my Pi Zero and a 5v 11a power source (PC molex connector). Following this guide: https://www.thegeekpub.com/15990/wiring-ws2812b-addressable-leds-to-the-raspbery-pi/ I want to use a logic level shifter (SN74AHCT125N). There's a 400 pin breadboard used in the guide, but I need to use a 170 pin breadboard because of the limited space the controller will be in. Here's a picture of what I'm planning to do, can anyone verify that it will not go up in fire and destroy all my LEDs?
I'm really for the messy sketch, it's my first time using fritzing, I hope everything is clear to understand.
