Title: P10 1/8scan 16x32 panels - current low price $11/ea + ship by Ray Wu
Post by: gadgetsmith on March 24, 2015, 07:42:17 AM
Just thought i'd post this in case someone was interested.

http://www.aliexpress.com/item/P10-Indoor-SMD-3in1-Full-Color-Led-Display-Module-1-8scan-320-160mm-high-quality/1599051786.html

I've purchased panels from these guys before (and PatDelaney too) from another listing they have for $18.80/ea shipping included.

These panels are currently on sale for $11.47/ea + shipping, so you don't really get below $18.80/ea until you hit 7 or more panels.  Over 10 panels, price drops to $10.89/ea + shipping.  Those buying 12 panels for a 3x4 matrix would pay $201.32, which works out to $16.78/ea.  That's a pretty good deal considering DHL shipping.  Buying more panels drops price even further, like 30 panels would be $15.36/ea

HTH someone.

UPDATE

As Reported by CaptainMurdoch:

Ray Wu has lowered his prices, so he is an even better deal right now.  12 panel matrix would be $15.94/ea (shipped).  20 panels drops price to $14.99/ea (shipped). 30 panels drops price to $14.49/ea (shipped)

Just for reference, the current code in FPP only supports the 1/8 scan panels which are normally 32x16.  I will be ordering a 64x32 or 32x32 to test with but I haven't yet looked at the changes required to support those if any are even necessary.  I would hold off on buying any 1/16 panels until someone tests or support is confirmed.

Oops. I put the title as 32x64, that is not correct, it is 16x32, which is the actual product in the link I provided. I'll try to correct that when I get home unless someone can do it as an admin. Sorry about the confusion.

That's a great price, especially in bulk. Looking at the specs, they list brightness at >1200cd/m2, and the boards on Ray Wu's store list brightness at > 2000cd/m2. That's quite a difference!  In large quantities, his price is $13.63/ea. Here is the link to his: http://www.aliexpress.com/store/product/P10-rgb-SMD-3in1-full-color-indoor-LED-Display-screen-unit-board-32-16pixels-320mm-160mm/701799_866772137.html
Am I missing something?

I bought a dozen P10 LED panels from Shenzhen Evershine Opto-Technology Co., Limited (12.67 each + shipping).  Had no way to check them out for a week so I accepted the shipment through AliExpress.  Turns out that all but one panel worked fine. I then E-mailed the vendor and they stated they would be happy to send me a new panel when I shipped back the bad one. I have to admit that their add said that the buyer pays return shipping but on a defective product that they will throw out!  So after checking shipping cost (even the cheapest way was greater than the cost of the panel) I E-mailed them that I would not be shipping the panel back, all my future orders will be with other vendors and I would leave poor feedback. And now this is part of the bad feedback.
I think I'll give Ray a try with my next order, his price looks good, I've never had any problems with my previous orders and he takes Paypal when you contact him directly.

Wow, did Ray drop the price of his P10 panels ($11/panel)?? 12 panels with shipping $191.27....what am I missing? Excellent price plus dealing with Ray is a definite plus!

Yeah, I think he dropped his price.  Someone must have emailed him.  :)  I think he was over $20 per panel before shipping last time I checked, that's why I was considering looking elsewhere.  I am now looking at getting some panels from him instead of the ones I was looking at getting.  I still have to place an order with him for some other stuff, so shipping may come out a little cheaper even.

Anyone know if Ray provides the short cables and magnetic mounting post with the panels?

Post by: JonB256 on March 26, 2015, 05:46:13 AM
He did with mine. (but I did specifically ask for them).  I got 4 magnets per panel, one HUB cable per panel and a bunch of "dual ended" power cables.

Just thought i'd update with a link to Ray's site as he looks to have a good price on these as Capt has mentioned above.

For the sake of full disclosure I am listing the entire E-mail that I just received from Sarah at Shenzhen Evershine Opto-Technology Co., Limited.

Dear Maffei,
At first, please accept me apologized because Sarah is out of office this week,
Just come back and get your email and your feedback from Aliexpress.

I think there are some misunderstand between us, because our company have a rule: if our product have problem, customer send it back,(Some control card price is far higher than shipping value ) we will send new one to customer, but we will return the shipping cost to you, my dear.

Here i talked with our boss and agree to send new module to you soon, don't need to send that broken one back, ok?

we don't want to lose any good customer, sincerely wish to become long-term and friendly. partner with you

Hope to get your forgive and revise the feedback in Aliexpress, we will appreciate you so much!
And we will send new module to you soon

best regards
Sarah

Chris,

I enjoyed speaking with you at the Expo.  I was the person who brought in a Pi-2 for the image set-up on Thursday and you said you were a few weeks away from having the image ready for the Pi-2.

After several sessions inside the little room and in your class, I know what I want to do this year and it is this:

I want to make one single row of 24 panels to hang from my lower eve so my question is this:

Will this be possible to do with my Pi-2 connected to the FPP, then circuiting out to the BBB/octoscroller set-up?  Will this set up support 24 panels or will I need to do two BBB/octoscroller combos?

And, is there anything else I need to address?

Thanks for all of the information at the Expo.  Pretty exciting stuff!

Charles, while the Octoscroller / BBB  can support 64 panels, because of ribbon cabling, I think you'll need 2 BBBs.  First one in the middle of 6 and 6. Second between the next 6 and 6.

If you only needed 16, then you could do 8 and 8.

The gents in Australia say they've been successful with 5Meter cables from the BBB to the first panel with ferrite cores at each end.  I ordered a few cores from my supplier to test, and will report back here.  Here is their post:

Jon,

That is what I thought would be the case.  You actually showed me the matrix outside the little room on Thursday but that was my first look.  Glad to see you are nearby Rowlett (Dallas suburb).  I am certain that I will need help when the time comes.

Is this because of the overall combined length of the ribbon cable going out 12 panels in each direction from center or because the outputs on the octoscroller will only do 8 per?

Post by: JonB256 on July 19, 2015, 08:48:31 PM
I'm certain that ribbon cable length, just like pixel wire length, is a "distance to first device" problem.

If, as BradsXmasLights says, the 5M length has no problems, then you should be able to get the job done with a single BBB and Octoscroller.

Since you want to do 24, my suggestion would be:

From left to right:  8 panels on an output, then 4 panels. Then the BBB in the middle. Then 4 panels, then the last 8 panels. That would mean even your longest run is well under 5M

I think there is a limit of 256 pixels (8 of the 32x16 panels) on each of the 8 octoscroller outputs.

I have a 2 meter ribbon cable, I can test that later today. I need to put ends on it.

I tested a 2 meter cable and that looked just fine. I don't have anything longer at this point to test with.
FYI My test was just with a single panel.

A better test, that I can do later is to use it in on my 24 panel matrix. That way I will be able to see if the intensity of the colors changes on the section of the display that has the longer cable.

Pat, thanks for testing. 2 Meter cables will make some pretty big displays possible. 5 Meter is even crazier!

Now we need someone to test the max distance between panels. :)

Theoretically, if you can go 4 feet between panels, then you could span a 64-foot width with a single BBB/Octoscroller by interleaving the panels and chains.

I need a longer cable to test, but I also want to put a really long cable in my current matrix and see if there is any "Loss".
I'm not sure exactly what is going on under the covers, but my thought is that my current "Jumbotron" is 24 panels. That is eight panels per output.
The configuration is 8 panels wide by 3 panels high, all mounted vertically.
Row 1 is on output 1, row 2 is on output 2,... and so on.

I want toe test a really long cable on row 2. If there is any loss, I should be able to see it.

Hey Captain, didn't think of interleaving the panels and yes that can make mega arrays possible, easy to test as well
