Fuck all those shitdesigns that interface with their LCD using flat graphite cables!
USE FUCKING COPPER WIRES ALREADY!!! At least those things can take a small fucking tug of gravity during disassembly, unlike that micron-thick graphite junk which fractures even more easily than my goddamn toe did!!!

And as mentioned on Hackaday (https://hackaday.com/2012/09/...), repairing it is hell. How much does it cost to make a decent copper wire.. I can buy those things for like 20 cents from AliExpress, so don't tell me motherfuckturer that you can't. And these copper ribbon wires last on ya, AND can be repaired with a simple soldering job. Unlike this FUCKING GARBAGE!!!

    @fuck2code a fish can't live without water for long.. neither can I live without devRant for long :3

    Wait, what are graphite cables? I thought all cables were copper. How do you recognize that shit?

    @Fradow well, it's indeed shit when used in circuits, but because graphite is a good conductor, it can be used to form conductive traces. In theory you could actually draw your own circuits using just a pencil. But its susceptibility to fractures would be extremely high, just like the ribbon cables. I've just taken a picture of the one that caused this rant as well ๐Ÿ™‚ they're black, very thin and are garbage in terms of stability and an absolute pain in the ass to service. Many LCD's use them to cheap out on what should really be copper ribbon wires with a mechanical connector.

    @Condor Thanks for the explanation and the picture! I can't remember seeing those yet, but maybe I just didn't pay enough attention.

    @Condor looks like this whole device costs about 20cent๐Ÿ˜… so yeah would be an expensive addition

    @stecchino could be yes.. there's some more components underneath to sense temperature (it's essentially a cheapo thermometer) but I've honestly got no idea at what price it's been bought. Some acquaintance of mine donated it to me.. I think he had water damage on it. Still worked perfectly when I fed it 3V while it was in its enclosure though.

    Probably it's €1 or €2 at most, for components, molding, designing and assembling the circuit and so on. But yeah adding 10-20% cost could be a lot at large scale... But still. At this point, all that's left for this device is disposal, because the ribbon cables couldn't last during the disassembly. Some people would call that planned obsolescence, enganeer'd to fail!

    @Condor haha yes, very typical for disassembling this type of cheap devices. Usually I just keep the print and cable together with my fingers and hotglue it, works most of the time of there is some contact. Ofcourse soldering is the better option but maybe not worth the time investment
