But I have a major problem now… The ribbon that connects to the display has a tear in it. I assume it got twisted the wrong way. This really puts a major halt to my project unless I can somehow repair it.
-
ouch…doesn’t look good…I have a 2 way mirror…but may look into this touchscreen option with mirror film
-
@cyberphox Yeah this is a major snag for me. I’ve read up on some conductive ink pins that might do the trick repairing this. If it turns out that it doesn’t though… looks like I’ll be ordering a new panel :/
However, when the touch screen was working, it was working pretty good! Even better than on the demo video in my original post (which was on a windows machine).
There is some tricky calibration stuff you have to do to get it to play nice with the pi though.
-
You’re better off replacing the ribbon cable, if you can find a replacement. You’ll likely have to desolder it on the other end, then resolder the new one on.
Or, alternatively, take the ribbon cable off and solder your own wires and connector on.

@KirAsh4 Hi! I was actually able to get this working again (with some help). I tried a bunch of different things to avoid soldering because of the plastic on the ribbon, but I got to a point to where I said “whelp, it’s already broken so might as well just go for it” and believe it or not, it works now! I had to remove some of the plastic to expose the copper wire on both sides of the split, but then after that the solder completed the circuit and it’s working fine again.
I also went ahead and electric taped the hell out of the connector where the split was before so that this doesn’t happen again. Some heat shrink wrap was also applied for an extra layer of security :p
-
Basically the pulled a MacGyver then … :)
-
@KirAsh4 Haha basically. It works in my case though, as long as the connection stays secure, since this will be inside my enclosure anyways (once I get around to making one ;)).
-
So a bit of advice: when you have an enclosure (which I hope is sooner rather than later), affix the ribbon cable to something permanent. Even if you want to put hot snot on it (hot glue), just something to immobilize it so it can’t accidentally get snagged on something and get ripped, or that you accidentally pull on it …
-
@KirAsh4 Solid advice! I’m not sure how I would actually go about doing that for this particular cable though… let me show you what I’m working with here lol.
It’s a pretty short cable haha. Of course, it does have a USB controller and other cables that actually run to the pi. I will be sure to secure those as well though.
-
Hrm, yeah that’s short. Though honestly, I would wrap it behind the panel and tape it there. However, it also depends on where the rPi actually sits in relation to where this cable is.
