Welcome back, Jeff Keyzer (@MightyOhm)!

ESD is part of EMC

UL testing

CE combines EMC and product safety

Radiated emissions testing

Worst case testing

We have had experts on EMC on in the past

Howard Johnson

Henry Ott

Eric Bogatin

Near field vs far field

H field and E field are separate

Standards are changing for LiIon

IEC60950 was the main standard for a long time

IEC 62368 is replacing some of these standards

Polluted rivers in Cleveland caused the Nixon administration to start the EPA

Head tax in Seattle

Chris and Jeff have both been living in/near the civil unrest happening in the wake of George Floyd's murder. The news plays up what's happening during protests, which are mainly peaceful.

We wanted to ask Jeff about abunch of the RF components we didn't understand in Episode 520

The main one was the power transistor and how it is tuned to particular frequencies

Miller capacitance between gate and drain

"Cut and try engineering"

Chris is still reeling from the Adrian Tang episode, with all the things he talked about.

Jeff was working on devices that went into WLAN and the now-defunct WiMax

All of the designs Jeff worked on were Gallium Arsenide

Former guests/sometimes co-host Piotr Esden-Tempski is running a new crowdfunding campaign for the Glasgow Interface Explorer (rev C)

Mark Rober is running a paid engineering course. Does it cost too much?

"Sounds like MBA projects"

Jeff has taken Tufte's visualizing information class

Joe Barnard on the CE Podcast

Starting real projects

Looking to relax? Watch Nick Offerman drink scotch in front of a fire in a "Yule Log" style video (for 10 hours!)
