so as far as the app you can grab the apk and decompress it and there is a directory that has all the bits to program it... evidently the app sends a heartbeat out so the app knows that the phone is connected??? also it is some kind of FSK using comwirelite library (???) and under the APK in apk file --> sources --> com --> generalplus -->comwirelite2 it breaks down the whole protocol for communicating with the unit as is.... :P
Thanks for the heads up. Amazon in the US has these for around $9 so i scooped up a couple just to tinker... of course only after wearing the flashy accessory a bit around town
I do like Adafruit for their custom made boards, but when it comes to things that they simply imported from China and are reselling (like the video walls), they mark it up a ridiculous amount. I get that they have tested multiple suppliers and have chosen the most reliable one or whatever, but their markup is still just way too high. And anyway, the people I bought from at aliexpress gave me decent support including newer software and profiles for my panels than the Adafruit support gives out.
It basically uses a bunch of shift registers where you can shift in the desired pattern for 1 line (or in this case for 1 line of the top half and another line for the bottom half). You then switch to the next line using the 3 to 8 decoder and shift in the pattern for the next line until you filled the whole display. This must be done fast enough to see a stable and flicker-free image (and to not damage the LEDs). To further control the brightness of the R/G/B channel of each individual LED you don't turn on the channel in every refresh cycle but just an appropriate number of times to achieve the desired channel brightness. (This is actually the naive way of doing it, there are smarter ways to keep processor load low). I played with a 32x32 panel a few years ago - 12bit color and a good refresh rate are relatively easy to achieve with a 8 bit avr running at 16 MHz, with some inline assembly 15bit are probably possible. Those panels are really neat indeed.
I've been doing a fair amount of work in an amusement arcade. Using huidu controllers and the AliExpress panels 5mm, 2.5mm and 2mm spacings. There's soo much you can do, and they're brighter than an LCD screen so great for signage.
Yes, when you think how much displays such as the jumbotron and black diamond must have cost even though the resolution was pretty poor by todays standards. Was watching some late 80's family fortunes the other day and was surprised that they for a while used a proper video wall (rather than the 90/00?'s episodes that used the yellow flip dot display), I'm guessing it was so expensive that it must have gone wrong after a couple of years and the cost of the flip dot display was still significantly cheaper than replacing/repairing it. You do get a nice load of close up shots of the display where each pixel is clearly visible. One interesting note was that when they were showing prizes people had won on the screen the resolution was so poor that they still had to broadcast a picture of the item, i doubt the resolution of the later flip dot display was that much worse.@@BigClive
11:33 - "Also because you don't want to blind people with your video wall handbag." Yes, considering they're probably already getting blinded by the almost fluorescent pink of the "bag" itself. Wow that thing is absolutely lurid...lol
Nobody cares about the purse or its color, rather the useful internals. And yes, it is lurid. We can split the $ and buy one, you get the purse, I'll keep the guts. And I'll generously let you keep the zip too!
@@111chicane Actually I agree that this is a wonderful way to buy a video wall or just a programmable LED panel on the cheap. I wouldn't buy this for the "purse" either, no matter what color it came in. ;)
It reminds me of the anti-paparazzi devices some celebrities carry. Essentially an LED slave photo strobe. So when someone tries taking their picture with a strobe, it flashes in sync pointing at the camera and washes out the image.
I cant believe I never thought to tell Big Clive about these. When I purchased them and left the review on behalf of our Makerspace fizzPOP, they where only £9.99 each in the black Friday sale. They are still a bargain at £15 though. I think in total the fizzPOP members purchased about 30.
I got 9 of them a week ago and now the LED display is being used as an art frame for 32x16 8bit images. It's a cheaper way to get LED displays for cheap vs the adafruit led display. I kept all of the screws and springs for other 3d printed projects. The rest of the plastic I tossed out due to not knowing what type of plastic it is, thus could not use it for 3d printing material. A Pi + the LED display will take up to a whee over 2amps of power when all 512 LEDs are white and 100% brightness.

Niiiice! I bought 2 of these on the clearance aisle at walmart about a year ago, they were $10 each! I've manged to wire it up to an arduino and control it with the adafruit RGBMatrixPanel library. I've been hoping you'd take something like this to bits so I could learn more about it, your knowledge of this stuff far exceeds my own. Ok, I'm unpausing and watching the video now.
I've JUST got into these LED panel setups and bought a 16x16 one and an T1000-S controller after having an addressable LED strip on my wall for gawd knows how long, then Clive uploads a video about one! Thanks man. I learnt a lot from this :) Still fcuking around with it though..
I created a project that drives these types of panels from an ESP32 as a wall clock display using NTP to stay synchronized. Ordering 3 to evaluate but I imagine the inventory is being liquidated.
Mine one is working well but when it fall down it's screen stop working but later it turns free red when press button it becomes of, than again on it but this time the half leds work and when presses half dnt work, I dnt know what happen can you help me and guide me how to fix this up?
The ZX-80 likely had more parts for the job than this board. The Z80 micro wrote to a port that set or cleared a flip-flop. This was the same flip-flop as did the sync pulse for the TV. I don't know if that means we have to count that flip-flop as part of the circuit or not. On this thing, I would bet there is little more than an RC on the way to a pin on the micro. The micro may have a UART in it. The audio would be awful to listen to but who cares.
The screen is smaller than a Windows 3.11 application icon :D However, put some "movie" made of only red pixels, attach some high capacity 6V to it, and fancy bike tail light :)
Finally got off my lazy tail and ordered the last parts I needed for this project (more bread-board F-F wires and a mosfet adaptor/barrel connector pair for the power) and can actually get it up and running! Thanks so much for this awesome idea (and cheap parts-source), Clive! I've been putting off a project for a while, but start on it tonight. The goal: I may be way older than the average rider, and yeah, people laugh, but I have a heavily modified older (1st gen, took a while to find one of those nice heavy-duty frames that wasn't cheap-from-china quality, but manufactured in... I want to say Michigan? Might have been Detroit though... But yeah. USA-made 1st gen model) Razor 300S (minus the seat, because no WAY am I sitting down at those speeds) that I have... adapted. I am a smaller person, in that I fit the "suggested weight range" for that scooter when it's OEM, but what would it be without a nice high-amperage ~600w motor upgrade, running at 36v vs the original 250w/24v one? Top OEM speed: 11-12mph. Range: 4-5 miles. Mine: max speed 42-45mph for 7-8 miles. And takes less time to recharge. My goal is to replace the aluminum deck panel (yeah, they weren't always plastic) with another one of the same, BUT cut a channel down the middle to put 3 of these boards end-to-end on it, then just put a thick layer (few coats) of UV-blocking shellac over them for protection. This would run animations under my feet while riding. Useful? Not really. But then... how many of these projects really ARE? Still worth it for me, as I've now spent a few months learning a HUGE amount about these 75HUB panels and matrix displays - I'd originally been looking at using APA102C panels, and the only thing stopping me was the cost. With these coming for as cheaply as $17? (what I paid, with shipping, on eBay for one) There's no reason left for me not to get on it, so now that my Amazon package has shown up, I should have a working prototype by this weekend. It'll start with basic animation, but I definitely will be wiring this into the lightning setup, which I'm already using a raspberry pi zero for. (Turn signals, brake light, headlights, power-monitoring/current/range logging via a serial bluetooth connection, so I have a constant battery level display etc (all on my phone for now - LCD touch panel comes later, heh. Still working on this thing, always making little changes.) - been using cheap bicycle turn signals etc and just wiring them into the pi for control there.) Thanks so much, Clive, for helping us out with these sorts of projects by tearing stuff down like this to show us how it's made, how it works, and how WE can repurpose the hardware. I love it!
Wouldn't be surprised if it's just passing on the RGB values in sequence. Just have to know how many steps it supports (is it a full 0 - 255?), the 1 and 0 tones, and its baud rate. Might also have something like an end code to page through a multiple image sequence and another one for the full loop. (Just trying to guess, but there's got to be some kind of KISS logic to it.)

Fizzpop person here, which is the Birmingham, UK Makerspace. That comment was from one of our peeps. The diffuser panel on the front was an important part of the cheap value of it. A lot of handbags were ordered and thus price rose from 10 quid to 15 and now 20 it seems. We are quite good at ninjaing on deals. We did a similar neopixel commercial thing for the now dead-ish Maplin As featured here: ruclips.net/video/qP1G6RUYejY/видео.html. Also The Adafruit stuff we used is here: blog.adafruit.com/2016/12/28/create-the-ultimate-holiday-jumper-with-arduino/ We had the honour of being rated as the best Christmas jumper in one article and the worst Christmas jumper in another article. Both articles from the Daily Mail. Reminds me of the stuff makes you healthier, same stuff gives you cancer stuff they do. I did a bunch of the animations and some cool ones were chopped out. A whole bunch of different stuff came out of the present for instance, My favourite anim was my jumper inside the screen which has a screen and so on, as it asks the question are we just complex animations inside a Christmas jumper? Does the regress end in a reality prime? the person modelling our jumper was a hipster someone hired to model it. Any questions?
Hi Clive. Please can you help me, I have a Christmas decoration which was running off a 24v and max 2.4va transformer. The transformer has now failed and I have an old one which I could use instead but it's a 24v and max 20va would it be ok to use this replacement transformer? Thanks, Toby.
It depends on whether the transformer outs out 24V DC or AC. Some of the new LED displays use a DC transformer and may rely on current limiting to avoid overdriving the LEDs. A chunky old AC transformer may also put out a higher voltage when lightly loaded.
i paused at 1:47 .. From the moment I saw this thing it's painfully obvious to me that somebody designed this for candy raver girls.. or like burning man festival girls, or just those girls that go clubbing with stuff like this.. And if it wasnt designed for them on purpose, lol then they inadvertently designed it for them.. I don't see any other targets demographic besides raver girls wearing all kinds of bright lights and glowing bracelets and necklaces and Candy jewelry walking around with this purse displaying things like p.l.u.r. love etc.. and all this other stuff or whatever designs and patterns.. and it also reminds me of Deadmau5 for some reason because of the Matrix display
After reading over the pdf Adafruit provided, this sounds distinctly like my very first addressable RGB circuit I built. It used a line of shift registers to update tri color LEDs. It worked pretty much the same; the signal would turn LEDs on and off, it required a clock signal, and to get faded colors meant a high update frequency (which my board couldn't handle). I then discovered neopixels and never looked back lol.
we use them in animated christmas light displays. Normally refereed to as P10 / P6 LED Panels normally 1/8 scan rates. you can drive them with a raspberry pi running Falcon Pi Player with a Pi Hat.
There is a trick for doing inverse polarity protection with a MOSFET. Basically, a P channel MOSFET is installed in the positive path with its protection diode so that it conducts with normal voltage. The gate of the MOSFET is wired to ground (via a resistor) to turn on the MOSFET. Reverse power switches off the MOSFET.
OK, just received the MC2 Smart Pixel Purse, BUT I can't upload anything from several SAMSUNG phones or tablets (the list of compatible devices lists several Samsung devices...) but I was able to upload my designs from old phone "ALCATEL Onetouch"; that isn't on the list. I think this can be because the input stereo-jack cable has non-standard order (and or reversed stereo contacts....). BUT I am interested to see if you can make the Arduino interface for the display to work. Are you - or anyone out there - able to help or point me to a solution? Does anyone knows if the stereo jack is using both stereo channels when writing to the unit? Or is there a way to make a custom cable to reverse/combine the stereo to a MONO output, so the software works on most phones? Thanks.
as someone else said I fully agree it would be lovely if you make a video where you address this panel with say an Arduino and show some graphics/text on it
There are two kinds of LED panel when it comes to how they plug, some use those same block connectors for power delivery and data and some have that molex style plug on them. this looks like one of the cheaper ones, though this looks like a 6mm pitch as well.

Hi Big Clive, I'm sure I've heard you talk about chokes and ferrite rings in previous videos, but have you considered devoting a video to methods you can employ to reduce video interference on systems like cctv installs. Were you have multiple cables running all over the house, across all manner of "noisey" pipes and wires, coupled with multiple cheap psu's, and ending up with noise bars moving across the monitor. Cheers Ant
$50 plus shipping on Amazon.ca... and that or more from any other seller in Canada. Just buying the panel from Adafruit is cheaper. I'll have to keep an eye out at the charity shops...
@@LiezerZero Plus currency exchange, shipping and import fees to Canada... works out to about $30 Canadian$$. But still a *slightly* better deal than buying it domestically. Thanks
Wow, the pricing on amazon is going up as I watch! I missed out on the $8.00 price, bought at $10.85. And just a few minutes later, price is up a penny. It's like buying on the stock exchange, such pricing elasticity.
Nice video and explanation. Nicely timed as I'm looking into replacing my 2mtr X 1mtr Chatteris Christmas Lights video wall (ws2812a) with these types of panel. Although i'm looking into the p3 (3mm pitch). They are driven through the hub75 interface. Linsden make the sender and receiver cards needed to drive an array of these led panels. Ethernet cables link the 2 cards together. This is my project for our 2019 display.
Life is all about angle of view on things. What is expensive plastic rubbish for one, there is great source of electronic stuff for others. "Really the cheapest way to buy a 16 x 32 LED panel...". This is right way to do: Always look on the bright side of life. Great vidya as usual Clive!
Yes. They are cascadable. It's the exact same panel used in many ghuge video walls. But they are often divided into blocks with a processor for each block.
I immediately want to run a cellular automaton on it. Conway's Game of Life is the most famous, but as there are multiple colours you could use Wireworld - which is a cellular automaton simulating electronics, complete with diodes.

Fizzpop person here, which is the Birmingham, UK Makerspace. That comment was from one of our peeps. The diffuser panel on the front was an important part of the cheap value of it. A lot of handbags were ordered and thus price rose from 10 quid to 15 and now 20 it seems. We are quite good at ninjaing on deals. We did a similar neopixel commercial thing for the now dead-ish Maplin As featured here: ruclips.net/video/qP1G6RUYejY/видео.html. Also The Adafruit stuff we used is here: blog.adafruit.com/2016/12/28/create-the-ultimate-holiday-jumper-with-arduino/
We had the honour of being rated as the best Christmas jumper in one article and the worst Christmas jumper in another article. Both articles from the Daily Mail. Reminds me of the stuff makes you healthier, same stuff gives you cancer stuff they do. I did a bunch of the animations and some cool ones were chopped out. A whole bunch of different stuff came out of the present for instance, My favourite anim was my jumper inside the screen which has a screen and so on, as it asks the question are we just complex animations inside a Christmas jumper? Does the regress end in a reality prime? the person modelling our jumper was a hipster someone hired to model it. Any questions?
I'd strip it back and have the panel on a display stand and have NYAN CAT on constantly...
I assume it would be MC squared as a pun based on E=MC2.
Just a heads up that as of now (mid-March, 2019) these are down to $8.30 in the US. 1/3 the cost of Adafruit, and less than half of Aliexpress.
Hi Clive. Please can you help me, I have a Christmas decoration which was running off a 24v and max 2.4va transformer. The transformer has now failed and I have an old one which I could use instead but it's a 24v and max 20va would it be ok to use this replacement transformer? Thanks, Toby.
It depends on whether the transformer outs out 24V DC or AC. Some of the new LED displays use a DC transformer and may rely on current limiting to avoid overdriving the LEDs. A chunky old AC transformer may also put out a higher voltage when lightly loaded.
Just bought 2 of these things on amazon for $7, and arrived next day! :D
Great .... now I have to build a video wall device :)
That's a very nice Led Board Big Clive
Great video big clive
i paused at 1:47 .. From the moment I saw this thing it's painfully obvious to me that somebody designed this for candy raver girls.. or like burning man festival girls, or just those girls that go clubbing with stuff like this.. And if it wasnt designed for them on purpose, lol then they inadvertently designed it for them.. I don't see any other targets demographic besides raver girls wearing all kinds of bright lights and glowing bracelets and necklaces and Candy jewelry walking around with this purse displaying things like p.l.u.r. love etc.. and all this other stuff or whatever designs and patterns.. and it also reminds me of Deadmau5 for some reason because of the Matrix display
After reading over the pdf Adafruit provided, this sounds distinctly like my very first addressable RGB circuit I built. It used a line of shift registers to update tri color LEDs. It worked pretty much the same; the signal would turn LEDs on and off, it required a clock signal, and to get faded colors meant a high update frequency (which my board couldn't handle). I then discovered neopixels and never looked back lol.
we use them in animated christmas light displays. Normally refereed to as P10 / P6 LED Panels normally 1/8 scan rates.
you can drive them with a raspberry pi running Falcon Pi Player with a Pi Hat.

There is a trick for doing inverse polarity protection with a MOSFET. Basically, a P channel MOSFET is installed in the positive path with its protection diode so that it conducts with normal voltage. The gate of the MOSFET is wired to ground (via a resistor) to turn on the MOSFET. Reverse power switches off the MOSFET.
OK, just received the MC2 Smart Pixel Purse, BUT I can't upload anything from several SAMSUNG phones or tablets (the list of compatible devices lists several Samsung devices...) but I was able to upload my designs from old phone "ALCATEL Onetouch"; that isn't on the list. I think this can be because the input stereo-jack cable has non-standard order (and or reversed stereo contacts....). BUT I am interested to see if you can make the Arduino interface for the display to work. Are you - or anyone out there - able to help or point me to a solution? Does anyone knows if the stereo jack is using both stereo channels when writing to the unit? Or is there a way to make a custom cable to reverse/combine the stereo to a MONO output, so the software works on most phones? Thanks.
I just love your new handbag.
Thanks, Clive! I just ordered one from US Ebay for $9.40 and free shipping. :)
Someone NEEDS to mod it to play doom.
The hero we didn't know we needed 👍 ✋
YES!
I got 2 for my girls for Christmas, now I know I can make them better or repurpose them if they stop playing with them
Aliexpress has LED video wall drivers that can be easily driven over LAN.
Feels so retro.
Compared to addressable LEDs it is. But most video walls still seem to be based on discrete circuitry.
love this one Clive. Fun eccentric object
These are typically 1/4 or 1/8 scan panels so only that many are lit at one time. My 1/4 scan board pulls about 2A when full/white on.
Clive, at CES this year there was a purse that had a bendable oled panel built in.
Would you happen to know the proper part to solder onto the board for the pass through connector?
I'd guess it's a fairly standard surface mount ribbon cable connector.
as someone else said I fully agree it would be lovely if you make a video where you address this panel with say an Arduino and show some graphics/text on it
I had to buy 3 of these after watching :)
This will be a embarrassing day at the
Post office 😅
Is there a way to use a USB power bank to power the bag in place of the batteries?
Hmm... wonder what you could do with some reprogramming, a Hippotizer and a Road Hog 4 console??
i hate that i know this but its mc (squared)
There are two kinds of LED panel when it comes to how they plug, some use those same block connectors for power delivery and data and some have that molex style plug on them. this looks like one of the cheaper ones, though this looks like a 6mm pitch as well.
Where did you say this product can be purchased at? Thanks.... I was able to get it on AMAZON here in the USA. There are several, one cost me only $9.99 including SH!
Where can I get one? :D
I just looked it up, the led matrix is cheaper than the handbag (at the moment)
why does the 3.5mm jack have gnd right left and mic on it? does it interface the microphone from the phone in some way?
You can get headsets with microphones in them.
Does it do any display if you play audio into it?
Great video big Clive
Are you left side of the slash, Clive? Your tone sometimes makes me wonder.

What happens when you plug headphones in while the app is running?
I'd guess you'd get bursts of noise. You could download the app and try it.
Found it on Amazon for < $10 US, prime shipping.

While Adafruit sells just the display for $25 ($35 on Amazon). Dooon't mind if I do.
it's $11.26 on Amazon now .. $12.76 on eBay up from $9.17
Me too. Just bought 2 😁
Could you link more than one of these panels together to make a larger video wall?
Yes. They can be linked in rows.
If you just want to build a massive array, Amazon has some 64x64 panels for $40.
NiHaoMike that’s perfect, I need them square because I want to try and build a cube and then make “digital dice”
Damn You Clive!!! I just ordered one!
Hi Big Clive, I'm sure I've heard you talk about chokes and ferrite rings in previous videos, but have you considered devoting a video to methods you can employ to reduce video interference on systems like cctv installs. Were you have multiple cables running all over the house, across all manner of "noisey" pipes and wires, coupled with multiple cheap psu's, and ending up with noise bars moving across the monitor. Cheers Ant

What!? Im a guy and i want that light panel!
Would love to see you use this in some kind of 1-off project.
I wrote some test software last night.
Where to get one?
"..cannot be used as a bag"
what?
What? No link in the video description?!
11:33 _...Just suppose I do want to blind people with my pink videowall handbag?_
Amazon US has them for $8. :)
Got 9 of them 2 weeks ago. Striped them of the panel and put the panel on a shelf for later use. Amazon has a 3 limit per order on it.
$50 plus shipping on Amazon.ca...
and that or more from any other seller in Canada.
Just buying the panel from Adafruit is cheaper.
I'll have to keep an eye out at the charity shops...
@@pileofstuffwww.amazon.com/dp/B071LQR2QG/ Total of 3 costs me about 27$

But still a *slightly* better deal than buying it domestically. Thanks
Wow, the pricing on amazon is going up as I watch! I missed out on the $8.00 price, bought at $10.85. And just a few minutes later, price is up a penny. It's like buying on the stock exchange, such pricing elasticity.
0:37 My favorite song by far!
interesting no idea what its all about is there an orange one ?
Nice video and explanation. Nicely timed as I'm looking into replacing my 2mtr X 1mtr Chatteris Christmas Lights video wall (ws2812a) with these types of panel. Although i'm looking into the p3 (3mm pitch). They are driven through the hub75 interface. Linsden make the sender and receiver cards needed to drive an array of these led panels. Ethernet cables link the 2 cards together.
This is my project for our 2019 display.
So far I've found free software called Ledstudio, for programming via a PC. Although I wish to drive the show from a Raspberry pi.
Could you try playing a normal audio file on it?
Multiplayer Tetris with arduino?
Nice strain relief on the programming cable! 8-)
Wish I'd seen this 7 days ago, I binned the display and kept the bag...
On things that didn't happen for 100, Alex
I love Pink Bags not shift registers...
hey where to get that magnifying glass
The video wall panel can also be purchased separately online
Life is all about angle of view on things. What is expensive plastic rubbish for one, there is great source of electronic stuff for others.
"Really the cheapest way to buy a 16 x 32 LED panel...". This is right way to do: Always look on the bright side of life.
Great vidya as usual Clive!

- _A lot of thought has gone into this!_
*The ziplock immediately falls off…*
Something to be seen with in the Glasgow clubs perchance? I'm off to buy some handbags tomorrow!
My question is, can you make a bigger version using more of these panels ?
Yes. They are cascadable. It's the exact same panel used in many ghuge video walls. But they are often divided into blocks with a processor for each block.
The headphone jack I wonder if it is a way to turn it into a color organ perhaps.
would make an awesome mod for a pc case - where to buy?
