AI Thread Summary
The discussion centers around the challenges of hand soldering small surface-mount devices (SMDs), particularly in the context of a challenge known as "SMD challenge misery edition." The focus is on the difficulties of soldering components like ICs, LEDs, and resistors, with an emphasis on the fragility of the smallest elements when using hot air tools. The conversation also touches on the existence of 01005 components, which are typically used in machine production, highlighting a shift in the discussion from 0603 to 1206 sizes. The participants express a mix of surprise and curiosity regarding the various SMD sizes and their implications for hand soldering.

@berkeman - remember the guy who asked about replacing 0603? Quite accidentally I just found something called "SMD challenge misery edition" (there are several versions, TBH I have no idea which one was first so I just grabbed the best picture I could find).

Yes, the idea is to hand solder the IC (which seems to be the simplest part), LEDs and resistors. Hot air will easily blow the smallest elements away.

Actually up to now I even didn't know 01005 exist :oops: (and yes, I know they are for machine production).

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
