We shouldn't be denied some custom Big Clive handbag graphics and a nice random walkabout with this nice handbag. Hear us Clive! Program the handbag, if only for shits & giggles!
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.
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
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.
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.
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.
@@mrb692 Yes they can be. You'll just need to put on a 16 Pin surface mount boxed header on the output side that will connect to the input side on the other matrix board. www.digikey.com/product-detail/en/sullins-connector-solutions/SBH11-NBPC-D08-SM-BK/S9187-ND/1990080

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.
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?
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..
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.
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.
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!
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.@@bigclivedotcom
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.
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 :)
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.
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.)
@@pauljs75 Perhaps something audio that drives an RS-232 port on the micro would be how it is done. Waaaaaaaaaaaaay back when folks stored data on audio cassette tape, a trick was to just band pass filter some RS232 and record it. Recovering the data involved an amplifier/comparitor and little else.@@pauljs75
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.
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.
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
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.
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
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: ua-cam.com/video/qP1G6RUYejY/v-deo.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?
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.
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.
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.
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
@@RocketboyX As a self-reference, she should do a project that involves protecting what's left of her modesty with a LED panel scrolling the source code to a Swagbucks mining script, or at least a link to that code. (For the record, I released the code to help other makers. If she ends up oversharing it so the difficulty rises so as to make the script useless, she would also be losing out.)
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.
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!
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.
Totally not the cheapest way to get LED wall panels, also you can get Linsn or Artfox LED send/receive cards online to drive them with dmx/artnet or even run video though a decoder. The parts themselves are pretty cheap for video wells. At least in contrast to lasers lol.
Very much up my street, nod to your friend who pointed it out. Anyone found a supplier in the UK? PS, Clive, have you looked at "smart LEDs" (neopixels)? Fully programmable led strips that cost not much more than the usual four pin strips
2 days later and the price has skyrocketed, they were as low as $8 and now they're hovering around $15 or $16, still better than $25 + shipping from adafruit though.
The dongle that apple provides with their jackless phones do not support a microphone (input) if I recall correctly. This won't work with apple products will it? At some point in the future, video walls will be 8K disposable OLED flexible panels on cereal boxes powered by a coin cell. Watch your 1 time viewable Spongebob episode while eating Capt'n Crunch.
$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.

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).

A Pi + the LED display will take up to a whee over 2amps of power when all 512 LEDs are white and 100% brightness.
Do you know if these panels are able to be “seriesed up” to make a higher resolution panel, or would you need a bunch of independent subpanels?

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.)
Anyone want to download the app and make a few test pattern and convert the audio to mp3? Shouldn't be hard to reverse it

Perhaps something audio that drives an RS-232 port on the micro would be how it is done.
Waaaaaaaaaaaaay back when folks stored data on audio cassette tape, a trick was to just band pass filter some RS232 and record it. Recovering the data involved an amplifier/comparitor and little else.@@pauljs75
wondering if Clive has a hidden, pink switch. . .and what happens when you switch it over to "Try Me" .
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.
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.
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
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.
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.
Someone NEEDS to mod it to play doom.
The hero we didn't know we needed 👍 ✋
YES!
Clive, at CES this year there was a purse that had a bendable oled panel built in.
Hmm... wonder what you could do with some reprogramming, a Hippotizer and a Road Hog 4 console??
Something to be seen with in the Glasgow clubs perchance? I'm off to buy some handbags tomorrow!
Where can I get one? :D
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.
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
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: ua-cam.com/video/qP1G6RUYejY/v-deo.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?
Is there a way to use a USB power bank to power the bag in place of the batteries?
Thanks, Clive! I just ordered one from US Ebay for $9.40 and free shipping. :)
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.
Could you try playing a normal audio file on it?
It's cool and it's pink. My prayers have been answered.
I just looked it up, the led matrix is cheaper than the handbag (at the moment)
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.
Where to get one?
That's a very nice Led Board Big Clive
Great video big clive
hey where to get that magnifying glass
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.
I'd strip it back and have the panel on a display stand and have NYAN CAT on constantly...
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
Just bought 2 of these things on amazon for $7, and arrived next day! :D
i hate that i know this but its mc (squared)
I could see Naomi Wu prancing around with one of these....
She can get the panels for way cheaper than we can - remember that she lives at most a few miles from the warehouse.
Dubious Engineering But she already did high resolution video boots.
I could see Naomi Wu doxxing someone with one of these.
@@RocketboyX As a self-reference, she should do a project that involves protecting what's left of her modesty with a LED panel scrolling the source code to a Swagbucks mining script, or at least a link to that code. (For the record, I released the code to help other makers. If she ends up oversharing it so the difficulty rises so as to make the script useless, she would also be losing out.)
or Mr. Humphries on "Are you being Served?"
I just love your new handbag.
Interesting that they left out one of the serial connectors but they left on the power connector even though they aren't using it.
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.
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”
What? No link in the video description?!
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!
interesting no idea what its all about is there an orange one ?
What!? Im a guy and i want that light panel!
would make an awesome mod for a pc case - where to buy?
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.
Great .... now I have to build a video wall device :)
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
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.
Multiplayer Tetris with arduino?
Would love to see you use this in some kind of 1-off project.
I wrote some test software last night.
The headphone jack I wonder if it is a way to turn it into a color organ perhaps.
Totally not the cheapest way to get LED wall panels, also you can get Linsn or Artfox LED send/receive cards online to drive them with dmx/artnet or even run video though a decoder. The parts themselves are pretty cheap for video wells. At least in contrast to lasers lol.
Nice strain relief on the programming cable! 8-)
0:37 My favorite song by far!
Are you left side of the slash, Clive? Your tone sometimes makes me wonder.
11:33 _...Just suppose I do want to blind people with my pink videowall handbag?_
How accurate can its color reproduction potentially become?
Close to 100cri
Aliexpress has LED video wall drivers that can be easily driven over LAN.
Shot in the dark here, but would anyone else like to arrange a group buy of these LED panels to get the purchase/import price down?
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?
Feels so retro.
Compared to addressable LEDs it is. But most video walls still seem to be based on discrete circuitry.
Very much up my street, nod to your friend who pointed it out. Anyone found a supplier in the UK?
PS, Clive, have you looked at "smart LEDs" (neopixels)? Fully programmable led strips that cost not much more than the usual four pin strips
Smyths toy stores had them for £15 a month or so ago
The video wall panel can also be purchased separately online
2 days later and the price has skyrocketed, they were as low as $8 and now they're hovering around $15 or $16, still better than $25 + shipping from adafruit though.
04:05
- _A lot of thought has gone into this!_
*The ziplock immediately falls off…*
The dongle that apple provides with their jackless phones do not support a microphone (input) if I recall correctly. This won't work with apple products will it?
At some point in the future, video walls will be 8K disposable OLED flexible panels on cereal boxes powered by a coin cell. Watch your 1 time viewable Spongebob episode while eating Capt'n Crunch.
I had to buy 3 of these after watching :)
This will be a embarrassing day at the
Post office 😅
It would be nice to put powerbank module instead of the AA's to feed cell phone and LED "Tube"
so clive, is this your first purse?
I plan to get one of these and retrofit it into my wife's Louis Vuitton as a birthday suprise.
can you daisy chain multiple panels together to make larger displays? Looks like maybe you can with those headers on the black board.
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.
$50 plus shipping on Amazon.ca...
and that or more from any other seller in Canada.
Just buying the panel from Adafruit is cheaper.
I'll have to keep an eye out at the charity shops...
@@pileofstuffwww.amazon.com/dp/B071LQR2QG/ Total of 3 costs me about 27$
@@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.
