Amazing, isn't it.. using white paint to cover up your shitty design. Time to introduce the white spirit I guess... And if I find the motherfucker that's responsible for this shit, pour some in their fucking face too 😠

    Can confirm, Design is shitty

    What is it? πŸ€”

    @kaae a wall outlet with some USB sockets in it (that I bought today and immediately destroyed all warranties for). Opened it up to see how it converts the 230V AC into 5V DC, and whether it's anything decent. Doesn't seem to look good so far though...

    @condor thanks for the explanation ☺️

    Finally.. it's cleaned up πŸ™„
    Single diode rectification instead of a full bridge, a 1A fuse for the USB that's only rated for 5V 2.1A (aka 10W) and should draw no more than 0.1A from the wall, i.e. this fuse ain't protecting shit. The fuse should've been of a much lower value, because this won't blow even when 20 amps are being drawn from the USB ports.

    @Condor wow..! Pretty impressive work there captain. Looks slick and fresh new 😎

    @bioDan at the end I destroyed it though πŸ˜… I disassembled all the THT parts but since there was also paint underneath (because why the fuck not), it made desoldering very difficult as the paint made it remain stuck to the board. And when desoldering the transformer I didn't know that it connected 2 output stages instead of one. Basically I disengaged one of those pin pairs from the wires in the transformer, and am unable to recover from that. This project is dead πŸ˜” it's a win for the certified motherfucker that made this pile of shit.

    When i disassembled a real 5v usb charger for my phone it wasnt much different from that...

    Unfourtanetly even good companies want to minimalise expences where they shouldnt. If its good enough -> send it.

    True, even the big brands that you pay good money for are often like that. Except that instead of paint, they use glue or they seal the enclosure with heat (so it can't be easily opened) or something like that... Planned obsolescence is a real problem nowadays.

    Ehhh. Planned obsolecence is realy visible sometimes -> led lightbulbs on example, two of them just mailfunctioned because they use crappy self-oscilating power supply with overheating caps. No regulation IC, low quality caps and leds might last for years but the power supply wont. I wish we would still be living in old days whe everything was fixable. (as uncle told me about it)

    @Gregozor2121 me too. But even more so than crappy (often proprietary) shitcode and planned obsolescence, there's also a boatload of shitty electronics designs out there. It makes me wonder how the fuck those "engineers" and "designers" can sleep at night, especially if it's supposed to be used with mains electricity, meaning that their crap could potentially burn down a house.
    Actually, I've just had yet another of those craptacular shitdesigns. A heat gun where the "certified designer" designed it as such that the plastic fucking melts during normal use. Glass fiber reinforcement? Something better than sewer pipe ABS? Nope.

    To make matters even worse, this heatgun was manufactured in Germany, a place that - to me at least - is known for good engineering...
