#190 - Let’s Hear It For The Buoys - Vanishing Vessel Vexation
- 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.Â
- 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).Â
- 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 ARMÂ 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.
