HUB 75 LED sign tutorial | LED Art App

In this video I show how to set up a HUB75 video wall panel and driver as a LED sign. These panels and driver boards are widely available on the likes of AliExpress and relatively inexpensive, my driver cost just over £4 and the panel cost about £12. The panel I got came with the data and power cables, but its worth checking this before ordering. HUB75 is the name for the connector, and data standard that the drivers and panels use to communicate. It is designed for video walls, which are basically massive TV screens often seen on the likes of concert stages or as electronic billboards for advertising. These video walls are made up of lots of smaller panels to make maintenance, and installation / moving them easier particularly in applications for the entertainment industry where they need to quickly move from show to show. This means that we can chain together multiple panels to make as big of a sign as you want. You can do this by taking another data cable, plugging one end into the data port marked OUT on the 1st panel and plugging it into the one marked IN on the next, repeat this as many times as you like (but do check your driver board can support that size of screen). You might need to adjust the screen size when connecting the driver board to the app, do this by deselecting “Use hard wear settings” and set the size according to the dimension of your full array. (also bear in mind that these panels can be power hungry, if you have more than 2 or 3 you will probably want to use multiple power supplies, each feeding a few panels. The 0v reference should be shared via the data cable, but if it isn't, or you aren’t sure connect a wire between the 0v (GND / negative / black wire) of each supply DO NOT PARALLEL THE SUPPLIES! This mean ONLY connect the negatives, do not connect the VCC (5v / positive / red wire) wires from multiple power supplies together, this is extremely bad practice and risk damage, or worst case fire if the supplies start fighting each other causing massive current flows in wires not designed for it. Install the LED art app, and power the panels and driver. Once the driver board is powered on, (I think you can do this via the micro USB port, but I don’t recommend this, as you risk overloading the port, I recommend using the screw terminals to power it) it will start outputting a Wi-Fi network. The default password for this is 88888888 which you absolutely should change in the app immediately. You will then have to forget the Wi-Fi network from the board and re-connect using your new password. You can now programme your sign however you’re like. As I mentioned in the video its worth thinking twice before installing the app on your daily driver phone, given the warnings on Google Play Store surrounding privacy protection. Especially as the app requires location privileges to access the driver via Wi-Fi. This is because by using information about which Wi-Fi networks you can see, it is possible to triangulate the physical location of the device to within a few hundred meters. I don’t think this app is malicious, and my antivirus didn't flag it, but it did make me pause when I saw it. Thank-you very much for watching, and as usual drop any comments, questions or suggestions below, and I will do my best to help.
