EXAMPLE

Make Scoreboard OCR send data to Overlays.UNO

Scoreboard OCR will work with most overlays that I've tried, the ones that have "OCR INPUT" are a bit cleaner, but all seem to work that I tested. 

Some clocks you have to send the MINS and SECS separately. 

If the values are changing in the GUI but not on the scoreboard itself, sometimes pressing the "restart"

 button on the GUI will help.

1. This example uses the "Football Scoreboard" in overlays. 
   
     
   
   
2. Open up your overlay,
   click on "Copy Uno Token"
   
   
   
   
3. Open up ScoreboardOCR
   Select your capture method.  There is a demo that coms with ScoreboardOCR
   Select "Choose Output"
   
   
4. Select "overlays.uno" from the drop down menu box
   
   IMPORTANT!!! 
   The token you copied in step 2 can sometimes contain a URL. 
   You only want the token value at the end. 
   Suggestion is to paste it into notepad or similar to modify there to look like the example below, then paste that into ScoreboardOCR.
   
   https://app.singular.live/apiv2/controlapps/YOUR_TOKEN
   
   Example:
   https://app.singular.live/apiv2/controlapps/6bKOvgHGqouD50d6
   
   
5. Paste your URL into the box
   (make sure the box is empty as it is easy to have values hidden to the left of the entry box) 
   
   
6. Click on 'ADD'
   You should see something similar to the screen shot below
   
   
   
   
7. If you see a red box like this example, your syntax or token is wrong.
   
   
   
   
8. Click on "Add Digits"
   
   
   
   
9. Now click on 'ADD"
   
   
   
   
10. Click on the down arrow in the upper right corner
    
    
    
    
11. If you see data like this, showing a bunch of different values, then your scoreboardOCR is talking to Overlays.UNO.  These values are the ones available to you in Scoreboard OCR
    
    
12. Select "ocrClock" and click "OK"
    
    
    
    
13. Select "Time (mm:ss)"  
    
    
14. Click "OK"
    
    
    
    
15. Select "ocrClock" then click "Automatic"
    
    
    
    
16. Highlight the clock in your scoreboard.
    Make sure that the highlighted value is the same as the data on the left (and changing appropriately)
    
    
    
    
17. Goto your Overlays.UNO scoreboard and you should see the clock changing
    
    

If you don't see data, couple of things to check.  First, bounce the CLOCK input. 
Set it to a different value, then set it to OCR INPUT  

You can go back to "Choose Output" on the Scoreboard OCR screen, see if the box is "Green", indicating its sending data successfully to Overlays.UNO

Now you can adjust items like the scores, by repeating the steps above

The example below we've added "Team 1 Score" and "Team 2 Score"

Once your data is connected between the two systems, going back to "Choose Output" in Scoreboard OCR and hovering over the Overlays.UNO entry, you'll see more code that its sending. 

Might be handy for troubleshooting

Upgrade Catalyst 3560-cx series pd firmware

This will explain high-level of how to do it by TFTP

Make sure your switch is on the same vlan network (or accessible) to your TFTP server.

Install a TFTP service.  This document uses TFTPD64 for Windows.

I feel there are lots of docs that describe how to install and configure.  

Point the "BASE DIRECTORY" to that folder.  I bound the TFTP to an ip of 192.168.0.50 because I have several NICs in my machine.

In the switch, go into ENABLE mode and issue the command

copy tftp: flash:

It prompts you to Provide the IP of your TFTP box, the source file BIN name and the destination file name (same name).  These files are generally available from cisco, but you will need to create an account.

If all goes as planned, you'll see something like this in your console

If you want you can verify the MD5 has of the file

Set the new image to boot (example below using the latest firmware as of writing)

Config t

DeskSW(config)#boot system flash:c3560cx-universalk9-mz.152-7.E13.bin

Then exit from config mode

exit

Then copy the run

copy run start

Then reload the new update

reload

Give it about 5 minutes to go through the boot process for the update firmware

Change the Windows 11 Boot Screen

You can use a program called HackBGRT on GIThub to modify the Windows 11 boot screen

The standard warnings are that you can potentially mess up a system using this, so you should tread with caution.  

This video by Techy Druid really helps to explain it!

Basically, you create a BMP and in the folder that you download there is a file called SPLASH.BMP

Save the file there (as a bmp)

Run the tool (AS ADMINISTRATOR)

The first option will be to "INSTALL" or "i"

Press that.  You will be shows the SPLASH.BMP page in PAINT.  You can make additional adjustments if you want, then close the file.

The rest will happen automatically. 

If successful, you can reboot and it will show the boot screen you created.

NOTE:

Chances are on a reboot you'll get a verification error message similar to the one below.

CLICK "OK"

Perform a Key management

Select Enroll has from disk

If asked, select the drive containing your boot drive

Select "EFI/"

Select HackBGRT

Select Grub64.efi

Select 

CONTINUE

Select YES

Select REBOOT

You should see the image appear as your systems starts.

Run Multiple instances of OBS

In windows for awhile, you could just double click the icon a few times for OBS and just launch additional instances on the same machine.  That changed during some recent updates in 2025, so this is how you do it now.

1. Download OBS, but download the ZIP file
   
   
   
2. Unzip it
   
   
   
   
3. Go into the unzipped folder and into BIN->64BIT 
4. right click on the file called " OBS64 " 
5. select "SEND TO -> Desktop (create shortcut)"
   
   
   
   
6. Rename that shortcut to identify it.  I renamed mine to end in " 1 "
   
   
   
   
7. Right click that short cut and select "PROPERTIES"
   
   
   
8. In the "TARGET" box you will see something like " 4-Windows-x64\bin\64bit\obs64.exe "
9. add " --portable " to the end.  It will look like this.
   
   
   
10. Apply those changes.
    
    
11. Repeat the unzip steps for the number of instances you need. 
    Unzip the same download, but to a separate folder
    
    In the example below I'm unzipping the file again, but this time to a folder that ends in -2
    
    
    
12. Repeat the same step with creating a short cut, renaming it to identify it (in my example I added a "2" to it as well.
    
    
    
    
13. Here I have two instances running.
    
    

Scraping music or VLC video source data in OBS using TUNA

This will show how you can parse some data out of an OBS VLC Playlist.

First create scene with a VLC Playlist with some content.  

In this example there are two MP4 files with color bars.  ColorBars#1 and Colorbars#2

Install TUNA

https://obsproject.com/forum/resources/tuna.843/

Open OBS and go to TOOLS - TUNA SETTINGS

Select "ADD NEW" 

In the "OUTPUT EDITOR" window

Click on the "..." in the "Song info Path"

This will be the TXT file that TUNA will store the info it collects (to be read by OBS later)

Create a file name and click "SAVE"

In this example we are creating a file called "TunaTest"

You'll be taken back to the "OUTPUT EDITOR" window, at the bottom under the variable list, there is a blank bar. 

Enter in the value: {title}

Click on "OK

You'll be taken back to the "TUNA SETTINGS" box.

You should see something similar to below, showing the "title" in the song format, and the path to your text file.

At the bottom of the window 

Select "SONG SOURCE" as "VLC"

Make sure that "Tuna is Running" (press start button if not)

Click on the VLC tab at the top

Beside scene, you will see a drop box containing the different scenes in your OBS, make sure it matches the one that contains your VLC play list.

Beside "SOURCE" you should see your VLC play list, click on "ADD"

You'll see it appear at the bottom

Click on "OK"

Go to your SCENE that contains your VLC Play list and create a "TEXT (GDI+)" source

Select "READ FROM FILE"

Click on "BROWSE" and select your TunaTest file

Click on "SELECT FONT"

Give it a suitable size for your test

Align your test

Assuming your VLC play list is playing, you should see this value changing between the different file names
