Bad design, using 2 sensors rather than 3, remove the usual method of disabling the MCAS, not taking into account airspeed as an additional stall warning....and... blogs message boards chat Drone Designs Demand Comprehensive Circuit Protection Henry Yu, Global Strategic Marketing Manager for the Electronics Business Unit, Littelfuse, 3/26/2019 Comment now All drones are susceptible to many of the same fault and failure conditions, ranging from merely annoying to catastrophic, making robust electrical protection essential. The generic drone design in Figure 1 highlights some of the areas where circuit protection is critical. Is It Time to Cut Back on Study of Classic Analog Filters? Bill Schweber, Engineer, Author, Editor, 3/25/2019 Comment now Analog filters using inductors, capacitors, and resistors are critical to most circuits and systems. Whether as passive or active designs, it sometimes seems that they have been studied "to infinity and beyond" via theoretical constructs with very intense math, with practical "application note" designs and BOMs, and even with hands-on circuits with ... Use it or Slew it Kendall Castor-Perry, Filter Wizard extraordinaire, 3/25/2019 Comment now How were you taught to determine the slew rate needed from an opamp? Ok, trick question; you were probably not taught that at all. But you'll have heard that an amplifier is "suitable for circuits where the output has to slew at up to 10 V/us" because the data sheet says the slew rate is 10 V/us. Let's see why this ain't so. The Solar Boat: Electronics preserving the environment, Part 2 Busy Blogger, Busy Blogger, 3/25/2019 Comment now The autonomous solar powered boat is a great solution which utilizes electronics technology to realize a zero-impact for connected navigation on the water such as the case of the interesting SeaCharger experiment (see Figure 1): Is soldering by hand still needed? Bill Schweber, Engineer, Author, Editor, 3/25/2019 Comment now I'll confess: I really enjoy making a well-crafted solder join between two wires or soldering a component onto a PC board. There's something very satisfying about the smell of the rosin (we won't talk about the lead fumes, of course) and the crisp eutectic transition of the solder between its solid and liquid states at 183 oC (for tin 63% /lead 37% ... An E96 formula: How Can You Resist It? Kendall Castor-Perry, Filter Wizard extraordinaire, 3/16/2019 Comment now 3 comments Spreadsheets are brilliant for filter design, and I write much less design software these days. Don't get me wrong, I love the BASIC interpreter that I use, BBC BASIC, available in a native Windows version and a multiplatform version (Windows, x86 Linux, MacOS, Android, Raspberry Pi and even iOS) using SDL2.0. It's a compact but complete Windows ... Most recent post, Sfinx, 3/20/2019 2:52:01 PM I certainly agree that exact design pays off for single amplifier biquads. ... The Solar Boat: Electronics preserving the environment, Part 1 Busy Blogger, Busy Blogger, 3/16/2019 Comment now A boat's propulsion system is usually fuel-based, with emission of exhausted fuel into the sea which pollutes the sea water and damages the environment. The introduction of the solar boat is necessary to preserve our planet, which is mainly covered by water; the autonomous drive option is a pleasant alternative (see Figure 1): Pre-APEC latest Product Introductions Steve Taranovich, Editor-in-Chief, Planet Analog, 3/14/2019 Comment now SAR Converter with PGA Achieves Dynamic Range of 125 dB Steve Taranovich, Editor-in-Chief, Planet Analog, 3/13/2019 Comment now Editor’s note:I am bringing you another of Relatively Asked Questions; this one authored by Thomas Tzscheetzsch, Analog Devices Boeing MAX 8: Technological advances and pilot training Steve Taranovich, Editor-in-Chief, Planet Analog, 3/13/2019 Comment now 8 comments I live very close to Luke Air Force Base in Litchfield, AZ. F-35s fly over my home every day. I have met some of the young pilots flying these electronic aircraft in the local supermarket (See my EDN article on the F-35 here) These “kids”, but I must clarify---very talented and well-trained “kids”, were not too long ago playing ...

Brushless-DC motor systems for the uninitiated Matt Hein, Marketing Manager, Brushless-DC Motor Drives, Texas Instruments , 3/11/2019 Comment now 2 comments After only a few years of being completely immersed in the culture of motor drivers, it is very easy for me to take for granted the fact that most people are not familiar with electromechanical spinning. This has gotten me into multiple conversations in which I should have proverbially thrown out the shovel rather than digging myself into a deeper hole.

David Ashton on Boeing MAX 8: Technological advances and pilot training 3/20/2019 5:41:13 PM question: Great article, but I got a question: what does it meant that a specific country blocks the Max 8 flights in his territory? Does this include international routes that fly above that country? thanks, formationinfo on Boeing MAX 8: Technological advances and pilot training 3/20/2019 3:45:50 PM Boeing Max 8: Since the MAX 8 is an upgrade to the venerable 737, many foreign airlines have decided that intensive training is not required in the new aircraft. This will, I believe, be a reason that the final verdict will be largely attributed to... tmazuben on Boeing MAX 8: Technological advances and pilot training 3/20/2019 2:52:01 PM Re: Precision C0G caps are much lower price now: I certainly agree that exact design pays off for single amplifier biquads. I've found that cell-based suvvessive design works better for tunable state-variables for apex legends free coins ... Sfinx on An E96 formula: How Can You Resist It? 3/20/2019 10:08:27 AM You can't train around bad design: Three thoughts: 1) Commercial flight procedures need a complete re-think. A pilot isn't necessarily going to have encyclopedic knowledge of these increasingly-complex aircraft, so he needs access to something like the Mission Control team... Finleythewombat on Boeing MAX 8: Technological advances and pilot training 3/18/2019 6:17:16 PM Re: Precision C0G caps are much lower price now: Thanks for that, Mike! I guess my incessant moaning (and that of others with larger production runs <g>) about the lapse in cap supply must have paid off some time in the last decade! The radio guys certainly need plenty of... kendallcp on An E96 formula: How Can You Resist It? 3/18/2019 1:54:04 PM Good summary: This is the best article I've read on the subject. I think 99% of the fault lies with Boeing. They took away the usual method of disabling the automated stabilizer, pulling on the stick, for no good reason. 1% for the pilot... DaveR1234 on Boeing MAX 8: Technological advances and pilot training 3/18/2019 12:50:20 PM Not unseen before: These crashes remind me of the Lufthansa Flight 2904 crash at Warsaw (1993) ( https://en.wikipedia.org/wiki/Lufthansa_Flight_2904 ) plus some other crashes that could be backtracked to automated systems with less-than-optimum requirements specifications. We'll...

Please let me know what you think? To me, I still say that more intensive training is needed on this kind of aircraft and lots of simulator time.... steve.taranovich on Boeing MAX 8: Technological advances and pilot training 3/14/2019 10:26:01 AM Excellent: Great article Steve with great insight.

Bob_D on Boeing MAX 8: Technological advances and pilot training 3/13/2019 9:04:06 PM Re: Yet another brushless type: Hello Mr. Sinnett, After having spent several years dealing with stepper motors, I have decided that they are the Pandora's box of motors. If you want a simple, low-power motor for position control, a stepper motor is easily the best choice.
