My Lightberry setup finally died and I've taken this as an opportunity to refresh my project. I'm upgrading to an RPi 4 and ezcap269, and rebuilding the LED portion as well. All the questions here are related to the setup and control of the LED's. I've purchased a roll of SK9822 LED's, 4 pin wires, and connectors. I've broken the build into 2 components: control and power. Taking on the control portion first. To control the lights from the RPi using a direct connection I'm under the impression that I would have to install pi-blaster. Then connect RPi's GPIO Pin 19 to the LED data and GPIO Pin 23 to the LED clock. What configuring is needed for pi-blaster and Hyperion to work together? Power. I realized today that my old PSU is inadequate for the new LED's, I have just under 4 meters of LED's at 18W/m so I'm looking for a +75W PSU. As for connecting, my plan is to connect the PSU to the +5V and ground. The RPi to just the ground (GPIO). Are there any egregious flaws in my setup or significant improvements that could be made?
