- Chris has been having trouble getting into a work grove while on his own. Dave “told him so”. Chris is now trying out Evernote.
- The “Screen Snip” function of Evernote is similar to the recently released Datasheet.net.
- The MH370 tragedy is also quite an intriguing mystery. Freescale had many employees on the plane.
- Former guest of the show Greg Charvat has been on all manner of TV programs explaining the radar systems used for search.
- Recently they figured out that they could use the doppler shift of the signals being sent out from the plane to help locate the flight path. This has never been done before.
- Dave’s former project, the Sonobuoy, is likely being used to help pick up the sonar signal.
- As discussed when Elecia was on the show, Dave’s firmware decides to scuttles the buoy (sink it to the bottom of the ocean) after a certain timeout period.
- An Aussie researcher used Sonobuoys dropped in a relatively close location in the Indian Ocean to see how far the currents drift…the answer? Quite far.
- Chris referred to the EAC, which was talked about in Finding Nemo.
- Chris will be attending EElive next week. Will you be there? Former guests Elecia White, Bunnie Huang and Jack Ganssle will all be speaking at the conference.
- The Computer History museum is NOT next to the McEnery Convention Center, it’s in Mountain View. It’s the “Tech Museum of Innovation” in downtown SJC.
- Sparkfun got dinged for importing yellow multimeters. This apparently violated Fluke’s “Trade Dress” in the US (not to be confused with Trademark).
- The Fluke response was nice, but predictable.
- Chris has been stressing about finding a sub-$100 oscilloscope (even if it’s a “throw away”) for Contextual Electronics Session 1B. It needs to be available worldwide and a standard product (ie. no recommending an analog scope). Right now he’s looking at:
- DSO Nano v3
- Hantek 6022
- Are there others he should be evaluating?
- Dave started with a Kikasui 20 MHz scope that he paid $800
- Do you feel imposter syndrome? This is a rising trend in the software industry, we were curious is the same happens in hardware. It’s easy to feel inadequate with so many people making YouTube videos and submitting stuff to Hackaday.
- What do you use for your bare metal ARM toolchain? Alvaro writes about his GCC based approach.
- A nice article about how short term thinking and the finance/bean counters gutted manufacturing in places like the US and Australia.
- Does Silicon Valley have a youth problem? Depends which side of industry you’re in.
- Dave and Chris both wonder where hardware startups are headed. How many connected devices can a person handle?
- Dave made an in depth video about power supply ripple

Thanks to Mike Baird for the picture of the buoy.
Hi Guys
With regard Evernote, — Great app! Highly recommended! I encourage you to check it out. I’ve been using it for several years, both as an independent technical consultant and in my new engineering job. It is cross platform, with strong search capability and a very useful tag facility. It runs on my Mac, Windows, Android and iOS devices, so my notes are always at hand, regardless of the device I am using.
I use daily notes to track hours in my “timesheet” notebook (in place of a paper journal)… this used to drive my invoicing as a consultant. I use the tag feature to record the name of key contacts on the daily timesheet note — over time, as the notes grew, I had a complete record of discussions with key individuals merely by searching on the corresponding tag.
I also used tags to capture items that were “data sheets” or “app notes”, from vendors with tag like “TI”, “Analog Devices”, etc. These get filed in my “Materials and Devices” notebook. The web clipper feature will capture magazine articles, full pdf files, or web pages with equal ease.
Finally, here is one that will work with DaveCAD… Evernote works with (ARM device based) electronic pens (mine is the Echo) from a company named LiveScribe. The pen writes normally, transferring ink to paper… However, you write on special paper that you can print or which is supplied by the vendor in various from factors (including quad-ruled, my favorite!). The text is captured as you write and can be imported directly as pdf files into your Evernote notebook, where it can be tagged, etc for later retrieval.
Like I said, this is a critical part of my daily workflow. Recommended!

Here is a recent IEEE Spectrum article regarding discussion beginning at 56:30:
The STEM Crisis is a Myth

Chris, regarding the USB scope with Linux, did you consider these guys? http://www.saelig.com/PSPCEL/PSPCEL021.htm
Ooo! I didn’t know about that one. I will have to get one to check it out. Seems like the first one with a Linux and Mac driver.
If Evernote doesn’t do everything you need, there’s always OneNote. I know, I know, it’s a Microsoft product. BUT there’s free versions abundant for iOS, Android, Windows Phone, Windows 7/8, Mac, etc. If your platform isn’t supported then there’s always the web app.
I’ve found it incredibly useful back in college and continuing to find it very useful in my career. It makes it dead simple to keep accurate and meaningful notes organized when working with various projects. I highly recommend it.
Regards,
Jason
In general, what’s the difference between a bare metal toolchain and one that installs with the chip vendors’ software? Ex. TI code composer for DSPs, or launchpad, Microchip’s mplabx, etc.
Regarding USB scopes, whats wrong with the red pitaya mentioned a few times on the show before?

Chris,
Check out the mydaq, it uses labview as is available in all three os’s.
it is available from studica as well, http://www.studica.com/National-Instruments-students-ni-labview-mydaq/ni-mydaq.html
Just got around to listening to this episode and wanted to give a +1 to the mydaq suggestion.
Although their out-of-the-box multimeter app Elvis only works on Windows as far as I know, the demos for Mac/Linux are easy to use. Most of my practical labs back in school used a similar lower-end NI device. The LabVIEW software is also free for academic users via NI’s website (although it’s a non-expiring student “eval”, Studica etc. will charge you $20 or so for a “permanent” license) and their drivers work with just about anything. I’ve even seen people use it with VBA, although I cringed a bit.
