EEVblog

Dave caught up with Karl von Moller at the Electronex expo in Melbourne and asked him about the progress on his Australian documentary State of Electronics.

Dave’s first Walk Time Rant. The sad death of Steve Jobs at Apple, and how Dave got shafted on his new EEVblog office space at the 11th hour.

Dave takes a look at the new generation $79 “stripped down” Kindle 4. How does it compare with the current Kindle 3 reader?

How to design, prototype and test a two cell 18650 Lithium Ion battery pack level gauge using the classic LM3914 dot/bargraph display driver chip. A favorite from Dave’s youth! Dave gives you all you need to know to implement a simple expanded scale voltmeter with the LM3914, without adjustment pots to tweak. This one works from 6V to 8.4V – the usable capacity of a two 2 cell 4.2V Li-Ion batttery pack.

Dave visits the Melbourne Hacker Space (CCHS) and takes along special guest Colin Mitchell from Talking Electronics fame.

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 :->) www.emctech.com.au

Ever wondered how they test mobile phones for radiation and impact upon the human body? Dave gets a tour of EMC Technologies $1M+ mobile phone (and WiFi) radiation Specific Absorption Rate (SAR) testing facility. Thanks to Jason Cameron from EMC Tech. http://www.emctech.com.au

Dave reflects on 200 episodes, his full time video blogging, and talks about some stats and the future of the blog.

Part 2 of the Tektronix MDO4000 Mixed Domain Oscilloscope review. This time, a world exclusive tear down. What magic lurks inside the die-cast shielded RF spectrum analyzer circuitry?

In another world exclusive, Dave reviews Tektronix’s new Mixed Domain Oscilloscope, the MDO4000 series that is released TODAY. Does it live up to the hype of changing the oscilloscope landscape and creating a new oscilloscope category? Also, it is a review of the MSO4000 series Mixed Signal Oscilloscope. How does that compare to the Agilent X Series? See PART 2 for the teardown!

Dave gets out of the lab for some fresh air, and a think about what the Makerbot $10M venture capital funding might mean.

The first EEVblog “RAW” Dave was assembling and testing some µCurrent kits on UStream and decided to record it. There is talk about his Keithly Instruments Voltage & Current sources, engineering statistics, and an open source hardware DIY Pick And Place machine. http://www.eevblog.com/ucurrent The thermal video is here: http://www.youtube.com/watch?v=GkVRX3h_A30 Around the 8:30 mark

30 minutes of Dave twiddling knobs on a 2nd hand 50MHz Tektronix 2225 analog oscilloscope – it’s right here! Who else can get so excited about a 500uV/div vertical scale?

Open your mind to Open Source Hardware. Dave gives you the low-down on what Open Source Hardware (OSHW) is, how it works, and some benefits of using it for your own projects.
