Title: FIRST TIME ADVICE FOR FALCON PICAP SET UP HERE IN THE UK
Post by: Discoeye on January 11, 2019, 09:23:05 AM
Hi to all on the forum. I am a uk resident setting out on my first adventure to controlling pixel lights via a pi 3b+ and a falcon picap
for christmas of 2019.


I am a complete novice of all devices but consider myself very competent if given the right guidance , i have read the best approach is to work backwards from the amount of pixels i will be using to determining the power required.


I value any help possible please from the forum to help me in my quest.


regards discoeye

So what specifically are you stuck on?  Installing FPP, wiring, configuring?

Hi,
thanks for looking at my post. I am awaiting my falcon picap and im confident with the software side of things with my pi 3b+ its just the wiring side of things.


My project is to make 4 chasing arches/arcs over a distance of 8 meters so 2 meters per arch/arc and i have no problems making these i thought strip pixels and tubing but im unsure on 5v or 12v lights and the whole wiring process.


Thank you and kind regards Discoeye

I think you'll be in pretty good shape.


Have you selected what type of LEDs you're going with?  Bullets/nodes or strips?  Are the LEDs inside some tube (i.e., weatherproof), or are the LEDs going to be exposed?


Basically, you want WS2811/WS2812 (WS281x) type of LEDs.  They have a wire/connector for VOLTAGE (5v or 12v, your choice), GROUND and DATA-IN (connected to DATA-OUT of your PiCap).

Here is a video on power calculation   https://www.youtube.com/watch?v=XxOdUJweQbA

Thank you ever so much.  So Picap on top of rpi 3b+ power supply to cap which would power rpi ????? lights from cap
would that be correct.


I have the link with regards to calculating how much power which will determine what psu to get, any additional wiring i need to know of or would be wise to have .


Forgive me for all the questions but i don't want to go out in a puff of smoke.


Thank you and kind regards Discoeye

Many people supply power through the PiCap--and this powers both the Pi as well as the LEDs that are attached (makes the overall wiring much simpler).


However, there has been some reports that the Pi 3B+ draws more power than the PiCap's on-board buck-converter can provide.  In this instance, you might need to power your Pi3B+ separately from the LEDs.

Ok thanks for the heads up. Any recommendations for a good power supply i think i will be going with 12v pixel strip lights.


Thanks and kind regards Discoeye
