Just a heads up I got for 10$ off amazon and it worked.

So if I'm reading the Wiki right, I should raise the blue gamma if I'm getting blue for 'gray' clouds? I did the white balance a bit and that helped

What is the windows grabber that does wireless to hyperion?

Edit: Found it here for anyone searching: https://hyperion-project.org/wiki/Windows-Grabber

Yeah, basically that, I don't want to wait because I have time now, I will not have time later. So the current PSU will work just not 100% brightness. It will allow me to configure everything. The power test was a random thought to get a baseline, not a huge deal just was curious if it would work(tried, didn't work) so I'll just account for that change later. It will still let me get most of the work done now while I have time.

It's a 240 LED strip. I know I can't do full on 10A but wanted to get everything setup while I was waiting for the final PSU to come in.

Sorry I have a 10A PSU currently but a 15A on the way, I just wanted to see if I could test brightness before wiring everything up to kinda have a base to go for.(that way I'm not overtinkering settings for brightness and such)

Also I can just power the LED without connecting the Data/Clock right? To test my power.

Just for clarity (apologies for the shouting .. It's important)

DO NOT RUN YOUR LED POWER VIA THE PI IN ANY WAY.

Don't rely on the Pi's USB input to get 5v on the gpio header.

don't loop power via the gpio pins that are connected together.

Don't try to power the pi via the gpio headers.

There's lots of different reasons why each is bad, but in summary -

DO NOT RUN YOUR LED POWER VIA THE PI IN ANY WAY.

Yeah I did some research and found that the 5v line is more for output than input and thus is not fused so if you don't have a consistent 5v or bad wiring you could easily destroy the pi.

So ideal then to just use a USB and terminate the extra power line(my strip came with a 4 wire connector and also a power barrel)

In order to power the whole strip at full brightness I went with 5v 15A PSU

Just to clarify, I can do pins to the clock, data, power, and ground on the RPi and I would eliminate need for the USB power right?

Bummer, just noticed my PSU isn't getting here for several days. Guess I can't set it up for a bit! I can get everything wired till then, or maybe use a 12V with regulator.

Well my plan was to use USB for Power so I guess I'll just do the ground, that makes sense though.

Okay so for the pi, why does the grnd have to go to the pi if it's connected to the strip?

So I suppose I'll do the rpi3 behind monitor. And wireless to it from Windows. Swap it out later for something like a zero. Don't have one of those yet.

For monitor it'll be about 6 inches or so from wall, slightly more at the curved edges.

I had a question or two. I made a setup for tv using hdmi split which works great. I used a lightpack though and wanted to go a bit higher def for my PC monitor, as well as go DIY. So I ordered a set of that come with the led connector and separate Power connector and I bought a power supply for them. Anyone have any info on going about connecting that to a PC or rpi for processing? Ideally I'd like to use my PC to process colors directly but if I need to output to RPi I will do that too. Just not sure how to connect to the PC.(USB, etc?)

Also, is there a huge benefit for facing the LED exactly perpendicular to monitor(Outward) vs angle, vs toward the wall? I was hoping to just do outward so I didn't have to cut/rewire the corners but it's no huge issue if it makes a big difference. Another thing is my monitor is curved, so that may change it up a bit.

For power, since mine has a power input on both ends. Do I need to splice a ground out of the beginning or end and connec to the RPi? Even if I want to use USB to power the pi itself and use the external power supply for LED?(if yes what is the point of this?)

Thanks!

PS: Have you seen the RGB headers on ASUS motherboard, curious if they're controllable through an API?https://rog.asus.com/19342015/maxim...-aura-lighting-control-and-rgb-strip-headers/

It was odd - I did a swirly video but the way the lighting was in it made it just look like it was lagging a bit, when in reality a combo of things were messing with it, super coincidental. Made it harder to troubleshoot =)

I'm having a little issue with blackbar detection now but mostly got it going well.

(see pic top bars aren't lighting up for black bar vid)

So I figured these out just through tinkering..

If you want to add a section to troubleshooting on Hyperion in case people run into these in the future:

Only certain parts of screen light up correctly:
Found two reasons for this. my lights were wired in wrong order for one(Lightpack)
Second, Lightpack only has 10 'LED's due to the way they're wired. Not 30.

Using V4L2 grabber if you have an issue with the screen going off the bottom that means you have the size wrong. Start out with -1 for height and width and see if that works.

When colors at at full intensity your lights are white, lower your luminanceGain in your config file.(1.5)

If your lights aren't bright enough, raise your saturationGain(I used 2.5)

So when I am testing external now(got the other working as above) - the bottom is cropped quite a bit even though my command has no crop(basically there's a small line of black at top, and about equal disappeared from bottom, it's like it shifted down. I did an mplayer test and it was showing correctly so it seems to be something with the hyperion v4l2

Think I figured it out, combo of 30 leds vs 10 and rearranging the inputs for Lightpack.

So I was seeing odd behaviour when running test videos so I bought up a 4 colored square and put it on the
screen, and moving it around I noticed if I put it on the left side of the screen the ilghts all stayed same color as the background. If I put it on the right side all the lights turned to the various colors of the square. Using Internal Grabber on Rpi2(Raspbian)

Also for some reason I can start/stop through HyperCon but can't seem to push config update. (I'll try to get logs for this)
