Dave goes on a tour of EMC Technologies new $1.8M RF Anechoic Test chamber used for automatic and product testing for EMC emissions and susceptibility.
Also their other test chambers like the GTEM (Gigahertz Transverse Electromagnetic) test facility.
Thanks to Rob Weir (Yes, he's a New Zealander)

Dave got a Makerbot Thing-O-Matic 3D printer. A look at what's inside the box, plus some bonus rants.
if it takes this long to un-box, how long will it take to build?
What's inside an old style bank note/bill accptor/validator for vending machines and the like?
How does it detect genuine notes from dodgy ones?

And Yes, the JTAG pins are there, right under my nose as labeled test points. Left side of the processor. Doh.

Youtube content creators, beware of this nasty and clever phishing scam that tries to get your Youtube login name and password using a fake content ID claim on your video.

Note: I was going to only upload polished on-topic numbered content to EEVblog from now on, but I figured this is important enough that it needs to be shared with as many people as possible. So my 2nd channel didn't cut it.

Dave debunks cordless anti-static wristbands you can buy on ebay for $1. Do they do anything at all?
Controlled quantitative static voltage measurements with a surface DC voltmeter are done to prove they are 100% bullshit!
And a direct comparison with a proper anti-static wrist strap and bonding point is included.
And a bonus tutorial on how to calibrate a surface DC voltmeter.
