Are you interested in a new Pandora LCD cable?

Would you want to order a new LCD cable for your Pandora for 30$

Good news: I found time to look into improving the production process for the cable samples and it is almost ok now:

These cables will go for testing now :) If they work inside a Pandora and do not break within some days, the project is ready to order the flex PCBs for the cables and then production can be done.
There is only one remaining problem with soldering the connector for the Pandora display panel. For these 5 cables, I had to check each connection pin under the microscope and repair some with a fine soldering iron. Since I do not want to do that for more than these 5, I have to think how to improve soldering the connector and find out where the problem comes from (e.g. warpage when heating of the flex PCB or the connector).
A final calculation shows that they can be offered at 34€ (incl. German sales tax), if I can produce (and sell) 100 units.

I mean is there special coating on it preventing teardown ?
No. I have no information how to make this and where to get it from and how to test if it is worth to be applied. But when being able to make these cables in small quantities it may be easier and cheaper to replace one again after let's say 3 years than trying to add coating and have 6 years.

Yes, but only a few people is able to actually change cables on the Pandora, so that also means more back and forth.
Anyway, this is better than no cable at all :^) .

@hns Ok, so do we have to buy at least 2 to get to 100 and keep the price low? Because I count around 50 people interested... and at double the price, I guess many will say now.
Maybe E.D. could want a few for his shop too, or was that already calculated into your calculations?

@hns Hi HNS, were you able to work on this project? Any progress on the testing of the prototype cables you made and were they durable?

I meanwhile started looking on how to remove the screen... I think I tried three times over the last months. Each time I'm close, but unable to loosen the top (without resorting to damaging my screen even more). So I'll enjoy my purple screen a little more (instead of breaking the ribbon by opening it.

Thanks for asking! We were not yet able to test durability... But I had an idea. This needs a hell-machine... It is not yet completely finished, but already looks like this:

It will wobble the display lid of a Pandora. It should be able to handle roughly 80000 open-close-cycles per day so in 12 days it is a million... So we can expect real stress :) And ED can make a video. Who knows, maybe he can do a setup with a webcam showing the scene, the pandora display (initially working an broken at some point) and the counter?

When will it be finished? Well, in 2 months...

Regarding the question how to open the display assembly, others can likely answer better than me...

You monster! You will subject your poor Pandora to torture? The heavens weep!
The contraption looks impressive. Be careful with the lcd screen, put something cushioning, or better, build a cage around the display. And remove the pin hinge, without it, the display goes floppy, but replace it with something that holds it in place.


Yes, a video! Like those Life stream videos on youtube? I think a few people, me included would watch that.


Thank you for the update. I'll ask again in 2 months....
