what's your recent fail?

Oh boy, I think I bought lt1468-2 instead of lt1468. No wonder my circuit oscillated.

I found that lt1468 and lt1468-2 are confused in many places, including in the part's datasheet and ltspice. I reported errors to analog.com and mouser, will see if they fix them.

Connected the /wr line of AD8251 to the positive rail instead of the negative  |O

My recent fail is thinking the global chip shortage isn't going to affect my small hobby project for some reason. I designed the PCB on the weekend and spec'd all the parts.
Got the message that the PCBs were shipped to day.
When ordering parts I find out that my chosen chip (TPS65253-5) is out of stock everywhere with 35 week lead time. :palm:

Well, at least I don't have to pay the import duties on the PCBs when I get a letter from the customs office. ;D
WattsThat:
FWIW, TPS65253RHDR DigiKey has 4300 pieces in stock.

I’m putting in an order tomorrow. Can post them in a padded bag to Germany for cheap if it’s just a couple of pieces.

Huh, I feel you here. I couldn't find opa2192 anywhere. Guess what, it showed up (but in weird qty of 24) in Mouser two days after I placed the order. It's so strange to see shortage on opamps, but it's not the first time. I found reports from 2018 that it was hard to get it. So, I'll try to substitute it for now.
