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. Dave’s 555 Timer T-Shirt is HERE Forum HERE

Dave shows a potential problem with Super Regenerative Receiver circuits, and looks at the issue of interference with his LED light remote control mains switches. Some fun with two spectrum analysers, a scope, a H-Field probe, and yes, of course a teardown. The Tekbox EMC near field probes Forum HERE

Dave visits the 2015 Vivid light festival in Sydney The guys from Robotic Systems talk about the technical details of their custom Game Of Drones LIDAR based quadcopter drone system they developed for Intel for the Vivid festival.

Dave installs a new LED lighting system in the EEVblog lab, with 9 x 60W 600mm 5000k ceiling LED panels. A look at hermaphroditic connectors. What kind of lux improvement is there on the bench? Has the colour rendering index (CRI) changed things? They cost how much? A look at Lifud brand LED drivers, with mini teardown of course: Forum HERE

Dave & David2 replace the bad caps in the old LG 50PF3DF 50″ plasma TV found in the dumpster HERE Will it fix the problems? Also an impromptu tutorial on how to replace bad/leaking/bulging capacitors, and measuring capacitor ESR in-circuit. Plus bonus banter. Teardown HERE PCB Sparkgaps Forum HERE

How secure are electronic locks used on safes? Dave tries a power line analysis attack on a standard La Gard (LG) 3740/3750 Basic electronic digital lock on a CMI home safe. Can you crack an electronic digital safe lock with just a resistor and an oscilloscope? All sorts of safe cracking techniques are discussed – thermal camera imaging, bumping, drilling, and spiking the solenoid. And naturally there is a complete teardown of the La Gard lock and a demonstration on how it works. And then Dave does something incredibly dumb, and has to fix it the old fashioned way, Hollywood style. It’s a tail of epic fails and stunning wins.
