Hello everyone! My name is Reinout and I'm an art student from the Netherlands. I've always been inspired by all the amazing Christmas displays I've seen online and on this website. For my graduation project I'm planning to build an 6000 RGB pixel tunnel that reflects the beauty of light. I have only 3 months to build and program this 60 square meter display and I really need some help. So, I'm not from Australia and I'm not working on something direct Christmas related... why am I here? Well; I figured that all the professionals on Christmas lighting are right here! Most of the information and tips I collected came from this forum so it was a logical step to me to ask you for help. I will be building a modular system made from custom plastic sheets (I worked for a plastic extrusion company a couple of years ago). These sheets will be lasercut into nets that kinda look like HolidayCoro's Pixnode nets. Every net is 1 square meter and will contain 100 LEDs, that's a pitch of 10cm. I will use 5V pixel nodes and will run it at about 60%, so power injection every 100 LEDs should work out. I'm not entirely sure if my wiring is correct, this is a rough drawing I made to show you my plans. (12v PSU should be 5V PSU) I will use the T-500K controller, it has 8 channels each controlling 700 pixels. Every net of 100 pixels will have 2 input cables with 2 pins. 1 cable with negative and data from the previous net and 1 cable with positive and negative from the power supply. These are the questions that I'm struggling right now: 1. Is my wiring correct or do I need to connect the negatives of the power supplies together? 2. Can I power 700 5V led's from 1 big power supply (with power injection every 100 pixels) and do I need a power distributor? I'm hoping you want to help me out, even though this isn't 100% a Christmas project. And if people are interested in how this project turns out I'm more than happy to keep you updated. Cheerio!
