Help required for Candy Canes.

[mccar]

I have built 8 candy canes as my first project. I have now got them all working but when I have all 8 running in a row, every so often they flash a different colour. Can anyone give me any ideas on why this is happening.
I have added a link to u-tube to show what they are doing. https://youtu.be/YsEWO4uxXwk


My setup is 8 candy canes each with 15 pixels (each pixel has 3 led's) I have power injections at the start in between cane 4 & 5 and then right at the end.


Thanks

I'm guessing its something in the sequencing. What sequencer are you using? Do you see it flash green in your sequencing program?

Pretty awesome candy canes. How did you make them?

I would also guess that the issue is in the sequencing. Try building a whole new sequence just for the canes from scratch.

Can you put them in test mode either via the controller, sequencer (assuming xlights) or da_e1.31?
If they still randomly flash using all white it could be a power issue, but if its during different colours, might be a bad data connection somewhere in the line.
If it doesn't flash during these tests, then it could point to the actual sequence/effect you are using in the video. As suggested above, try a new sequence.
Hope this helps

Looks to me like a data issue for the six pixels in each band that change.
Doing a freeze frame you see:
Yellow-Green-Green-Green-Green-Aqua
[attachimg=1]
The signal should go
White-Red-Red-Red-Red-Red-White
or FFFFFF-FF0000-FF0000-FF0000-FF0000-FF0000-FFFFFF

Everything seems to shift by one byte
FFFFFF-FFFF00-00FF00-00FF00-00FF00-00FF00-00FFFF which give the colours
White(from previous pixel) Yellow-Green-Green-Green-Green-Aqua

This to me indicates either:
- corrupted data in the sequence - so rerender and export
- bad data connection at the start, since the effect is same throughout all canes - Re check all data connections

Anyone else want to chime in on my theory?

Hope it helps

How about sending it data using my da_E131 software? If it's stable with that, the issue will likely be in the sequencing. Make sure you close your sequencing software while da_E131 is running.

Hi mccar,


Very effective, could I also trouble you on how you made them.


The angle of each segment, increases the effect.


Are they segments with 4 sides each.


What pixel type did you use.


Thanks in advance.

Here is a link to a cheap and easy way to make coro canes that I made a few years back

Any luck with this issue Mccar?

Finished these the other day. I'm not 100% happy. After finishing them I could see many way to improve them.

The maker should post his recipe but they appear to be holiday coro like...

See the assembly video how it comes together.

Hi Mike,


Thanks for the link, like you mention, it seems to be done the same way.

Tell us about some of the improvements you see?

Mike, I'm finding that I get lots of light leaking out of the sides. This has been created due to the size of the fronts. This is my fault due to The cutting them out process. Also, the hight of the sides is a little on the large size. I think I could of gone lower to bring the brighterness out in them.

Maybe it's me been to critical of my work.
