There are many wonders in electronics land. Even more await an engineer that stocks up at aliexpress to save a bit on his hobbies. Well, I needed a few RTC chips for some prototype hardware, so I picked DS1307. As usual, placed an order at aliexpress. once in a while shit happens .
No, this time they didn’t write ‘sex toy – 3$” on the customs declaration sticker, as they did on a parcel with a dozen of TRIACs a few weeks ago (Or, did I use TRIACs wrong my whole life! Should have asked them for instructions!)
Anyways this time I received some second-hand chips. Packed in a plastic tube, no flux whatsoever, but small solder blobbies are all over the pins. Without unpacking, I’ve made a few pics. Sorry for the quality, but I put my USB microscope somewhere far and my usual camera doesn’t handle focusing on something that close well.
