Put this together today, looking snazzy.

This is an old rv remote that i broke by stepping on it. I had to do something so i could watch tv. As you can see it cracked clean from the tip. At least the ir led was ok. I saw that it was only one layer. I always wanted to repair electronics so i always watch repair videos. With a big ass tweezers i scratched the mask and got to the lines. There was 6 line i had to connect. As you can see the joints are scary. Because i live in a 3rd world country and a student i had to the repair with a oxidated tip and a 40w soldering iron. No flux, just low quality fluxed solder. But the important thing is it workss. Yes its ugly bot nobody sees it and i know i did it. I gotta get me some good equipment fr. I just wanted to share my joy. Dont hold back anything say what you want.

Looks like the fuse burnt and spit out the board's protective epoxy or flux near the AC voltage terminals.

To all the fellow software engineers - I see your off-by-one error, and raise to off-by-two!
Can you spot a problem faster than me?

This chip failed to flash, but was erratically responding to some commands, took me hours to find the issue.

Well it is something simple, I even took it apart fro the support to see what was going under it. But I didn't was able to wath to much as, it was glued. So the rainbow cable was blocking the main ic.

Also, I watched a little drop of resin wich makes me think, that, or it was the main controller (not really sure, as the visible chips aside were plenty big), or it was just the e-paper driver. Maybe the second.

Anyways. Even being a simple thing, it looked awesome. I thought this e-paper screen were more slow to refresh their frames, but this seemed to work faster than I thought.

So this is my story of today and why now I want to buy an e-paper screen to test it with my raspberry zero 2w.

Also, I can't imagine how expensive that screen is. And maybe will just end up in the trash once the decide is not necessary anymore, or just if the batteries die 😓

Hope it ends on good hands in the future (mine if possible, maybe leaving a note like a post it, behind. I will do it xd).
