You can use a X Server on your Rasperry, and X Client on your laptop. This way you can use your laptop screen. no additional screen needed

[@mnelson10000]

Maybe VNC or something like that to connect remotely to the console instead of leaving a screen there at all...?

[@wickett7078]

mnelson10000 The screen I do beleive is just something he used to setup the first time, I am not sure though

[@turtleb01]

Vnc is too laggy if you don't have a true gigabit ethernet. By true, i mean those usb 2.0 to ethernet adapters that many single board computers have

[@snowmarkinhoskp]

Hi Scott. We need your help, as the glediator software does no longer exists!!

[@technologyunloaded]

You could use one of those small 7-10 inch monitors (touch one) and have it mounted to the top board and fold out when required?

[@SouthSideChiTown]

I am relatively new electronics hobbyist, I've been watching your videos for a long time and I'm very impressed by your level of knowledge and the way you explain things. I'm going to attempt to build this 15x10 Led Matrix , using your videos. How is it you know so much about Electronics? Is it your profession, or just an interest of yours? Thanks for all the information you post!

[@SkywardPvP]

FEMA Region 9 its both

[@Maisonier]

This is amazing! I'm searching for a way to replace my broken backlight of my old LCD with an array of LEDs. Will I note any improvement if I use COLOR LEDs or it will be worse?

[@KikkawaRyu]

Instead of using a physical screen connected to the Pi have you tried a remote software application to run on the run that you could then use to connect to a windows or mac machine? I've had remote software running before on pi one model so it should work find with the pi two. You could have the remote software open up upon boot so you're able to access it straight away providing the PI has a static ip to connect to all the time. Only an idea rather than having to use a phyical screen and such :) Awesome video tho!

[@wickett7078]

Kikkawa Ryu Thats the way I ran my Pi for the longest time, because I was too lazy to work in the corner that my networking was done(it was kind of crowded too) So i just remotely accessed it from my laptop or desktop and I found a software for phones but it wasn't too functional

[@AnnaVannieuwenhuyse]

+Kikkawa Ryu (Luke) And It'd also stress the Pi too much which could possibly lag the code :P

[@benhill391]

Thank You very much took 3 weeks. Raspberry Pi was a real pain --- but it all works graet.

[@austinkimbrough2660]

+Ben Hill HELP!! How did you get it working?

[@ConnorN97]

Should make a video of the black led reel configured to flash inside a computer, would love to know how to do that.

[@rebelstudios9640]

One great show indeed.. i ordered the Orange PI PC and recreate it (Small version see photos in your facebook). Last step... Trouble in he RXTX part, especialy the part where you have to set the path for java of the PI. It worked in my laptop but can't find the preinstalled java in he PI... Great job again and nicley explained video!!

[@benjipestell3677]

For the banana and orange why not use a lcd header conversation to hdmi of vga that way you could use a much later screen

[@rottenluck]

Excellent project, I always look forward to your videos.

[@ivanhuzjak9644]

Maybe you can make like pull out screen and make that rasberry pie form some command center of house or the room.

[@wishmaster-productions]

an idea for your screen problem with gladiator. u could try to use vnc to remotedesktop into the pi.

[@Tobi-xj8xw]

GreatScott! Can you make an tutorial for glediator

[@officialgood-boy8946]

I think it would be fun to attempt to build a screen with more leds (a lot more) like this that will show a signal from a computer or DVD player or something. Obviously wouldn't be the best quality but it still sounds fun.

[@rpdigital17]

Great video, inspires me for making similar project! Why don't you use 24-inch monitor or Full HD TV for your HDMI-output? Would that solve the problem?

[@wickett7078]

RPdigital I'd say he just find a dead laptop with a high res screen pull the LCD out of it and hook it up to the Pi

[@bartvanderhaagen986]

nice to explain it so well... do you think there is a possibility to control glediator with your android?

[@audibosoundandlight]

hey, i have an idea for your screen problem. You could use SSH to log in from an external computer and control gladiater from there.

[@christiankunner6895]

There is a question in your newer led matrix you are able to show images without a Computer. Am i right if i think you could also use this matrix without an raspberry pi and connect it directly to an computer which has the Gladiator software on it? If yes is there a way to get an Equalizer on it? Or maybe just some animations without a Computer like the new small one? It would be great if you are able to answer. Sorry my englisch is horrible.

[@chain3519]

I love the way you say banana!

[@TheFidelio2]

Hallo, hast du vielleicht mal darüber nachgedacht, die Farben über ein Smartphone anzusteuern?

[@Yevhen123]

Why do you use the arduino as a LED controller? I think the PI has all the data ports to do the same thing as the arduino but you may need a suitable software to run the LED controlling.

[@aidan3734]

Wow great project! FIrst question is are you able to use an arduino uno? I really want to make this but i saw a question on inscrutable that you said the schematic you made does not work, are you currently fixing it or have you just left it because i want to make one but I cant make it without a schematic?And can you use a regular windows laptop to run that porgram instaed of a rasberry pi?

[@deangreenhough3479]

Great project. You have inspired me. Keep up the great work, please post more videos and more frequently

[@FreshCraft242]

Place the LCD under the Acrylic Glass!

[@MarcoThomasSch]

I know, this Video is a bit older, but: Did you try to control Glediator via SSH and a X-Server for your PC? You'll have to have either a network cable or a wlan device attached to the Raspberry, but there is no use for the screen anymore.

[@sietse5902]

Hi at 2:32 you're adding the export commands to the bash.bashrc file. I'm trying to do the same but I'm not able to save the file. 'Can't open file to write' appears. How can I solve this?

[@3D-Amir]

I've tried to add those export lines but there doesn't seem to be any bash folder under ./etc ! Can you please tell me how and where to add those two lines if the folder/file doesn't exist in /etc?

[@rd12346789]

So I built one of these and I'm have a bit of trouble makeing the LEDs transition smoothly. The entire matrix flickers from a high brightness to a low brightness very quickly. When I run the gleditor program on the matrix it's like the colors lag behind one square. Please help right now it's 6x10 but the final board will be 9x10. If you can help please do! Thanks!

[@cicciothelynx]

Incredibile ! I wish i can become skilled as you in electronic :D

[@zulkarnainkarim]

i do not have the raspberry pi can i accomplish this method with just using nano and windows? can u make video about it?

[@mikegleasonjr]

So the pi and the arduino communicate together in serial through a usb cable ?

[@mcbain2k]

Nice project. Just use a wifi ,bluetooth or xbee zigbee connection from your rasperry with "big" screen to the pro mini, can be the solution for your problem.

[@diegito2468]

Wow!...it´s fucking awesome !!! .... I like this project. Greetings from Colombia

[@kulgan96]

have the lcd hidden inside and make it slide out with motors or embed it in the bar surface

[@elliotth30]

for a screen you could use your phone,laptop or computer by using ssh to have a remote desktop connection to your pi but this may be impractical depending on your Internet speed unless you use Ethernet cable to connect directly to the router? hope thats some help. Elliott

[@wickett7078]

***** Doesn't matter about the internet speed, it is the quality of the dongle's wireless protocal/speed and his router's wireless speed AC Wireless is the must up to date and fastest protocal I do beleive

[@Seppel00796]

Is there a way for Gladiator to automatically start up and open the serial port and start the animation playlist when you boot the Raspberry Pi?

[@officialgood-boy8946]

I wonder what the upper limit for something like this is.

[@alm9373]

How much PL9823 LED that can hookup for led matrix? I'm planning to go big; 2 sets of 20x25 led matrix...which is 1000 PL9823 LEDs.....

[@jbsthegamer]

I built all of this it works very good and i like it.

[@87TechReviews]

my brain hurts

[@ahmadhorik]

Same

[@kmcat]

Could you use a Raspbey pi as a Google calendar- wall calendar. I have an old LCD monitor lay around.

[@wickett7078]

C00m7ee Definately, wanna know what would make it even cooler? TouchScreen

[@TheGamingMaik]

you could try to display the pi porgramms via SSH on your PC oder Smartphone :)

[@toxm5]

You can use VNC to display the screen on your computer over the lan/wifi. Just search for "VNC Raspberry" in Google. After this is configured a physical display is no longer required.

[@franciscotiburehak488]

Great project! Greetings from Mexico

[@blackbackLP]

Benutze doch den 9" touchscreen von adafruit. Sollte groß genug sein. Freue mich schon auf Teil 4 ;)

[@GodxPoseidon]

Hey!!, I have a question. I have installed an RXTX library and the Glediator is not detecting my COM ports. Do you have an idea why this is happening? We are using RPi3 and an Arduino UNO Rev3.

[@mariusmatei258]

Hi!I would love to do this project as well and I would like to ask you something. I didn't find the PL9823 RGB LED but I found RGB PTH LED. Will they work like the PL9823? Another question is if there is a way to replace each led with another matrix but control it as one led. I want to replace each led in each box with another led matrix but control that entire matrix as one led. Is it possible? Thank you very much!

[@christianelzey9703]

What is the maximum number of LEDs that would be supported by this setup? I am planning on attempting a 16 by 16 matrix, with the possibility of scaling it up to 16 by 32 for a total of 512 LEDs.

[@Ringmaster860]

is it possible to use a HC-05 Bluetooth Module for going Wireless?

[@reypatey]

Der Link zu Part 3, am Ende von Part 2, fehlt. Tolle Videoreihe, ich versteh zwar meistens nur die Hälfte, aber es ist trotzdem interessant!

[@greatscottlab]

Rey Patey Jetzt sollte alles gehen. Danke für den Tip.

[@ElectronFunCom]

Nice project, it must have cost you a lot of effort. How much time did you spend building it?

[@greatscottlab]

ElectronFun.com Around 50-70 hours.

[@zawzero]

***** Glediator and Jinx! are both capable of Video capture. So you could use any tetris applet and send that to the matrix.

[@michal4561]

Maby a MHL v2 cable (hdmi+elec) to the secondary port on your tv/computer monitor or POE instead of a PSU?

[@BBL232]

You could use VNC and an iPad (or similar) to control it

[@Julian-vy3oo]

Bill Vandenberk Yes, with an iPad it would be very nice ;)

[@mimix1004]

it should be marvelous with an autologin and an auto start of glediator and a sound recording for moving leds according to the music ! do you know how to make that ? i have made an auto login for root user, auto "startx" in the batch file, but i have also added the command for starting glediator but that doesn't work if "startx" command is present, and without her, he works only if i launch th LXTerminal. and finally, the com communication in glediator don't start at the starting of glediator.

[@carloslabonde4315]

hi scott wie hast du das mit dem audio input für das sspectrum zum laufen gebracht. ich bekomme da immer die fehlermeldung dass das signal mit 44100 un pcm_signed sein muss

[@simonlachsl]

Hey Scott, I'm almost done with my 16 * 11 Matrix and now I'm confused by the software side of the project. You didn't upload the specific code that you used for the arduino, did you? It would be great if you could do this. The two codes that are on your site don't look like the one that you used in your video. Thank you for your Great(Scott!) videos xD. It's really fun to create something of that dimension.

[@simonlachsl]

+Simon Lacht OK i think i found it, it was in the next step of your Website

[@artarenliu5579]

I'm new to this can I do it without an arduino because I just bought an easy raspberry pi

[@diao77723]

can someone tell me how the LED's work, how do the data In/Out pins work and i get how a current can turn them on and off in an order but how do they change color and why do they go blue with no data input

[@foxelectronics4889]

Your Martix project is awesome! But i have one question I want to make LED Display using led strip WS2812b,so can i control the display using same proces like you did raspbèrry,arduino nano and gladiator software ? Please Help! #GreatScott!

[@foxelectronics4889]

+GreatScott!

[@SecretSchadow]

Hallo, Ich habe ein Problem die Signale der LEDs vom Raspberry Pi kommen bei meinem Arduino Nano an (denke ich, weil die RX-LED vom Arduino schnell blinkt und die L-LED leuchtet) aber dieser gibt keine weiter an die LEDs. Kannst du mir da helfen?

[@carlorocksss]

Hi Scott i have one question , what if i want to load a few animation created in gladiator to an sd card and make it Rhythmic?? thnks

[@Tobiaslg]

GreatScott! , first of all, i want too say that i love your channel. I resently found it when i got my rasbien, and I loved it from the beginning! This is just an idea, but I think it would be great if instead of making a wave when you clapped, it would turn of and on. Its just an idea, but i think that would be a great toturial/video! Greetings from me! (And have a nice day!)

[@greatscottlab]

Tobias L G I will think about it.

[@kdotdevelopment6398]

Now how do I make a game on this? And a controller + mouse?

[@eduardcueloakimista4383]

can i do this in my raspberry case? i want to mod the case because i don't like a normale black case

[@thilacsanthiya6256]

It’s only working with Arduino nano. Any know how to make it work with teensy 3.5 and other Arduinos. When I connect other Arduinos serial port is not showing in the gladiator. Pls help me

[@0o0ization]

This was mesmerising! Thank you :)

[@tonyk.8580]

I've got glediator driving my 9 x 47 grid and it works great with the premade animations. I'm finding the program a bit clunky though and was wondering if there are any other resources to learn how to better operate the software. Their website seemed rather limited imo.

[@SISKworks]

Any tips on how you got it to work? I cant seem to get the RXTX to work on the raspberry Pi. I've used the software a fair amount (on laptop) and I might be able to explain how to do something if you want.

[@nilsgoeke7494]

Why not hook up the cables directly to the raspberry pi instead of the arduino

[@megovatmegawat3162]

How to setup for computer !!!! please help me !!!!

[@svinternational6116]

Yes same problem ! I cant setup glediator for my PC !!!

[@nataliyazubreeva930]

Ye I would like to know to ! Thank you =)

[@greatscottlab]

MegoVaT MegaWat Follow the descriptions on solderlab.de

[@hamburgtech]

+MegoVaT MegaWat Maybe this video could help you, english subtitles.

[@megovatmegawat3162]

hamburgtech wtf man . how is has to do with a program setup for pc ?

[@matthiaslul]

+GreatScott! Could you control two or more Matrix with one Arduino Nano or would you need a seperate Nano for each Matrix although each matrix shall display the same? Thank you for helping so far!

[@NoeNoe-fe3qo]

So you need an arduino AND a raspberry pi??

[@TheS1l3ntOne]

Use a LCD from your old monitor and use the same driver

[@Rastafa469]

QUESTION: I want to build an LED display with WS2812B LED strips. There will be 225 leds in total. Should this work with the anrduino nano too or do I need a better microcontroller for such an amount of LEDs?

[@DoctorWhom]

The Glediator website mentions up to 512 pixels so you're fine.

[@BigManko]

Does the Pi need access to the network at every time? Could i set it up once, close the enclosure and it will start the display whenever i power the matrix?

[@ragon000]

I think Network was only for downloading the things, it should work Fine when you have seit everything up

[@ragon000]

*set

[@joachimpri]

@GreatScott! I really love this. I love all your videos. I wand to use this in a project that I am busy with, however, I want to use it in a more of an automated way. What I want to find out is do you have to start the animations from Glediator every time you start reboot the pi or will it start automatically on boot? also, do you have to use the Glediator application every time or is it possible to save the animation (like in a config file for instance) and recall it from python or the terminal on the RPi automatically based on certain conditions? You see, my led matrix will be unattended and based on certain conditions, I want it to display a Glediator animation or text automatically and I need to switch between these programatically. Does this sound possible? Keep up the great videos. Really love them. Thanks J

[@lucassheridon9809]

can I control this using dmx and a mydmx 2.0 from american dj

[@rOflkopter021998]

does glediator in combination with arduino work for windows too?

[@mixxx2005]

Hello, first of all - I like your channel, great content. My question is - is there a way to control "smart LED's" with just PC and arduino? Maybe you can provide any DIY or tutorial how these LEDs are controlled? I can not find anything useful for my basic knowledge. Greetings from Latvia ;)

[@greatscottlab]

mixxx2005 Maybe it will happen someday.

[@fi89298]

Wow great project !

[@pieceofcake9305]

Hi Iam trying to build a small led matrix with glediator but it's not working I have the rxtx library installed and it works the Rox light on the arduino mega flashes like you said it should but nothing lights up Iam using the lm9832 led and the LEDs work because I tested it with sketch2 and 3 on inscrutables but the code you supplied in part 3 didn't work could it be the arduino mega or is it a software issue I have tried other codes on the internet it would be great if someone or you could help because I am starting to get very angry

[@Noksus]

Awesome. I wish you'd make thse videos more often but you must be busy!

[@greatscottlab]

NikoliZZer This is still just a hobby and when you consider that it takes me 10-25 hours to make one video then you might understand why I can not post one of those every week.

[@Noksus]

GreatScott! Yes I definitely understand since your videos are superb detailed and fun to watch. All your videos are greatly appreciated! Thanks for replying.

[@greatscottlab]

You're welcome ;-)

[@SISKworks]

Is it possible to run Glediator from the Pi user? Everyone is telling me that it is not a good idea to always run as root user due to security issues. Since Glediator is all i will be using this for do I need to worry about that? IF not how can I make my RP3 startup in root user and auto run the Glediator? Is that possible? I already got it working if I manually login to root user but I really want to make auto happen after a reboot. Please help!

[@Amy-ft5mt]

hey greatscott can you make an LED text display?

[@Gnenguin]

Thanks for the videos! Will this work with the Raspberry Pi 1?

[@greatscottlab]

Yes, but the framerate is not pleasant.

[@Gnenguin]

Ah okay; thanks for answering :)

[@lucassheridon9809]

PLLLLLLLLEEEEEEAAAAAAAAASSSSSSSSSEEEE DO A VIDEO ON USING Jinx! software to control the matrix (Jinx is the animation software) wirelessly when connected to a raspberry pi! please

[@DanielMelendrezPhD]

Amazing job! Congrats

[@SecretSchadow]

Hello, I have a problem, the signals of the LEDs from the Raspberry Pi come with my Arduino Nano to (I think because the RX LED flashes quickly from Arduino and the L LED is lit) but this is no more to the LEDs. Can you help me?

[@greatscottlab]

SecretSchadow Seems like you made a mistake with the code for the arduino.

[@jake.jackson]

I have installed the rtxt and I get the same outcome as the video but it comes up with 0 COM ports when my arduino is on. Do you have any ideas?

[@jake.jackson]

I have found that even a broken arduino mega COM is found but not the UNO

[@Schmirgus]

+Jake Jackson got the same problem with my arduino uno.. found a solution? I think we have to install librxtx 2.2pre2-3, but didnt find a way to install it

[@stevemanley3685]

Very nice video, much appreciated. I just got my rpi 2 today and have been following the example but with an Arduino Mega. Trouble is the Pi still isn't seeing the Arduino as a com port. I have successfully installed Gladiator and it runs. Also successfully installed RXTX, but reports Number of com ports found: 0 I tried a couple of USB cables and an Arduino uno with the same results, any thoughts as to whats wrong?

[@greatscottlab]

***** I guess the problem is that you do not use a FTDI/CH340 IC. Try something like this: blog.oscarliang.net/connect-raspberry-pi-and-arduino-usb-cable/

[@stevemanley3685]

GreatScott! I loaded the Arduino IDE into the PI and can download sketches without issue so I guess this is just to do with compatability of my Mega and the RXTX library. I don't have one yet but what if I try a USB to FTDI cable?

[@Schmirgus]

+Steve Manley did you found a solution? my uno isnt working too

[@stevemanley3685]

+Schmirgus Hi, I bought myself a cheap Arduino Nana from China. It uses a knock off FTDI chip but works a treat.

[@Schmirgus]

thx for your answer :) yea i thought about the same, but i want to use the uno as a spectrum analyzer and sparkfun got a plug and play board for the uno. i found out, that on my pc with an dekstop linux build everything is working.

[@FennecTECH]

great scott i recomend not using an LCD on your pi at all instaid use remote desktop softare so you can control the software from a laptop :D

[@FennecTECH]

+Fennec Fox (FennecTECH) and put a folding@home or seti@home project on it so you can donate your unused cpu cycles to science C:

Why not run it all via a VNC server? Then just change it when you need too from your actual computer

[@thepotato9331]

looks awesome

[@anabecerril4531]

I am not sure why the Raspberry Pi is needed. Can't I just download Glediator to my computer and upload the code to the arduino from there? thanks!

[@tonyk.8580]

Yes you can, you will just need to manually ad the RXTX library to your java lib. Just google RXTX lib + your operating system and follow instructions.
