Hopefully in the near future I will be going back to school. As I remember so much of my time was spent doing big long equations that would fill up two chalk boards that only had one, two or three inputs. That takes forever when you have 40 data points you took during the experiment. I remember spend 10 minutes to figure out the equation once let alone multiple times.


Is there something where you type in the equation once then just feed it a few variables click a button then get your answer? I realize you can write computer programs to do this but I'm not a programmer and learning it would take away from my studies.

I really hope it'll be made free for STM32 too.

ST is actively making their toolsuite sexy and up to date, looking forward to the future.
Same! STM32 is quickly becoming my favorite MCU. Not only the software part is better overall (there's a bunch of other cool things like audio weaver), but the hardware itself is great. I've used several other ARM Cortex M MCUs (LPC Series, Kinetis, MSP432, Tiva C...) and STM32 is quickly getting ahead of the pack. My main MCU for the last while has been the Tiva C series which is an M4F but it's getting a bit limited for what I do. The STM32 has M7 parts, and price-wise its a much better value too.

Here's a simple, quick comparison between my "usual" TM4C1294NCPDT and the STM32F769BI, which does cost 10% more:
-M4F @ 120MHz vs M7 @ 216MHz; the M7 is about 50% faster at the same clock speed to begin with so it's a big gain (also supports double precision FP)
-1MB vs 2MB flash
-256KB vs 512KB RAM
-90 vs 140 GPIO -- more GPIOs which are also faster and more which are 5V tolerant
-20x12b @ 2MSPS vs 24x12b ADC @ 2.5MSPS
-2x CAN 2.0B bus vs 3x CAN 2.0B bus + also LIN (for automotive-style networking)
-1x USB OTG vs 2x USB OTG
-8x UART vs 8x U(S)ART
-10x I2C vs 4x -- the only place STM32 loses, but being a shared bus it's not a big deal IMO
-4x QSPI vs 6x QSPI which for flash also supports DDR transfers + dual flash so much faster, and also XIP
-both have 10/100 ethernet
-nothing vs 2x 12b DAC
-nothing vs MMC/SD/SDIO interfaces
-nothing vs 3x I2S and SAI (supports PCM, TDM, DFSDM, SPDIF, AC97...) for audio
-nothing vs LCD interface + MIPI DSI interface (for "mobile" LCDs, can also support HDMI) + Chrom-ART accelerator (with DMA) + HW JPEG Codec for HMIs (with free STEmWin and maybe TouchGFX soon too)
-nothing vs support for various "consumer" protocols like HDMI-CEC, DCMI for cameras, etc.

So: more than double the speed, twice the flash, twice the RAM, ~50% more GPIOs, better peripherals overall, and it absolutely destroys the Tiva C when it comes to audio or graphics...

Controllers, sensors and the like all depend on the end user and power level. Low-cost laptop adapters over 75W generally use a PFC with a inexpensive analog controller, although even there, digital is making inroads.

A 3 kW telecom rectifier often uses dual interleaved CCM boost converters followed by an LLC. Many have TWO full DSP-based power controllers, isolators, etc. They are very efficient across most of the load range, robust, with high reliability, and high fault tolerance. If you tried to do all of it with analog, you would never get the product out in time.

Well, I already have some loyality to the Rigol devices; and I think you mean the DP832A which has the high resolution and all other options already included; the 831 has one bipolar channel and a 5V max channel, while the 832 has instead of a bipolar two independend channels.

Like with the DS1054Z you can easily activate the additional options of the DP832 and turn it into a DP832A - with the exception of the colour display.

One important reason to stuck to Rigol is the fact, that there are 2 suppliers in CH, while there is none for Siglent; and it quite enough to import ham radio and accessories because of missing dealers, so I have no need to go the same way for the lab devices.

Renewable Energy / Re: When Will Electric Cars Become Mainstream?
« Last post by nctnico on Today at 04:36:27 am »
The transition to EVs is occurring whether some like it or not. When they will compromise a majority of cars on the road is anyone’s guess.  I’d guess it will happen 15-20 years from now IF society as  a whole can continue to hold together (a big if IMO).
We'll probably see a transition into electric vehicles which have a predictable usage so their batteries can be sized accordingly. Vehicles like city busses, airport shuttles, small delivery trucks can be made electric because it is easy to predict their daily mileage and size the charging infrastructure accordingly. But for general purpose cars I don't see it happen within 20 years and I wouldn't bet any money on EVs becoming the majority of the cars after that.

The smaller vehicles like bicycles, mopeds and small trolleys are much easier to electrify and people have room to charge them at home. This will probably eat into using cars. When I built a new shed I deliberately added extra outlets for charging a moped or an electric bike.

You are right about people buying cars on different factors than price. The commercials of car manufacturers always seem to appeal to non-techincal feel-good stuff. And there are lots and lots of rebrands so the same car from different brands can be targeted at different people. For example: The Ford Focus I own  >:D has also been sold as a Volvo. And it is the second car we have owned that was also sold as a Volvo.

RF, Microwave, HAM Radio / How to use BNC tees properly?
« Last post by technix on Today at 04:34:35 am »
I bought a few BNC tees so I can tap off the output of my function generator directly, along with a few 30 centimeter BNC patch cables. How should I use it?

* Mode 1: attach the bottom of the tee to the output jack of the function generator, and attach the output connectors (BNC or alligator clips) and the patch cable leading to oscilloscope input to the arms.
* Mode 2: attach the bottom of the tee to the input jack on the oscilloscope, the patch cable from the function generator comes in on one arm, and the output lead goes to the other arm.

Also is this an approximate of a network analyzer?

RF, Microwave, HAM Radio / Re: Can I embed these antennas in epoxy?
« Last post by Beamin on Today at 04:32:15 am »
Right, 1 is vacuum/air. PE foam is much closer to 1 and can be used to reduce close-field losses and antenna detuning. But even then you probably need to tune the antenna.

That was my suggestion then paint over it minding the type of paint. While foam is not vandal proof if it looks like what ever it is blending into people will have no reason to try and mess with it. Out of sight out of mind.

Where I live people will steal anything metal even if it's bolted to the ground they will steal the nuts too!

Here problem now might be getting insurance again. If I was her I wouldn't move from her current provider (who presumably still covers her), ever.
That's kind of freaky. I'm not too familiar with U.S. medical care (e.g. if they're private companies) compared to Belgium, where you don't have much incentive for leaving. That's indeed a... "strange" system.
Insurers as a rule are private, for-profit corporations here, which really explains quite a lot in and of itself.  I think there are a few not-for-profit insurers and self-insured organizations, but they are rare.  Insurance is usually provided through your employer, who often subsidizes it as part of your compensation, but as a result changing employers means changing insurance.  There are two primary public options here, Medicare (intended for retired folks) and Medicaid (intended for low income/disabled folks), but eligibility for those is inherently limited, and leaves big gaps where people don't make enough money to afford private coverage but make too much to qualify for public assistance.  Some states have opted to expand Medicaid, but many state governments are under right-wing control and have been fighting tooth and nail against any such "government overreach"  :palm:.  Many of the conservative politicians here are single-mindedly focused on shrinking government at any cost, including cutting all forms of public assistance and rolling back many of the health insurance reforms provided by the Affordable Care Act aka Obamacare.  It's shameful. 

Anyway, back to the pre-existing conditions thing, one of the ACA reforms was to prohibit the denial of coverage for pre-existing conditions, so in theory she's okay for now, but who knows how long that protection will last with the current government.  Personally, I've had a different insurance policy each of the last six years I've been at my current employer simply because whatever plan we've picked for a given year hasn't been offered the next year.  This is largely due to insurers attempting to cope with the tremendous uncertainty caused by the current government's constant attempts to undermine the ACA reforms, and since we're a small company we have zero bargaining power with insurance brokers.  We'll see what happens with the elections in the next few months, and again in 2020, but it's going to take a long time to fix what's wrong with the US, if it can even be done.
