I confirm that the SiTime 1532 MEMs oscillator (in the newer iPhones) stops functioning after a few minutes in a helium environment. Frequency first rises, then drops to 3KHz. Oscillator will not restart after power cycle. Full video soon!

Mandag morgen, kollega kommer inn på kontoret med sønn (som har tøff fargerik propell-lue på), og sønnen utbryter: «Hva gjør vi på...? Jeg jobber ikke, Pappa!»
Very envious of all that were able to get a ticket and go to #EMF2018, it's barely started and already looks like a blast :(
Oh, and to all those sites that pester me about Cookies to be warm and fuzzy about their GDPR compliance... Could you please start using a Cookie to remember that I've (50 times) already accepted your use of cookies ...
Why do all vendor-supplied VHDL/Verilog dev-environments take so much space, suck so bad, and create such cluttered working environment/workdirs? 10-18GB to blink a LED... (And IMO the solution is not "go OS" with ghdl/icestorm/.. I am trying to learn, and need training wheels.)

Reminder, because I keep seeing “burner phones” discussed in regards to DEFCON: A burner phone is a carefully-procured device intended to be used only once, & be untraceable back to you. A DISPOSABLE phone is a phone you don’t care about losing (or infecting with malware, etc.)
