555 Timer IC Oct 21st

A very cool home project - you can build a working 555 timer chip out of individual transistors. It's one thing to know that ICs are made of transistors, it's another thing to assemble it by hand and then have it be usable. The very first PCB I made in school used a 555, so this is very cool.

2014 was a wild time for iOS, and the creation of Becky! was truly the zenith

More on Havana Syndrome, courtesy of @matts - Science Vs have done a podcast episode on the phenomenon. Lots of good info in there, but their conclusion is a little disappointing

I've been following the "Havana Syndrome" story for a few years, and it's just keeps getting weirder. The BBC had a good summary of what we know.
