Yeah, I think it's the same idea as driving a sports car- the aesthetic and performance is without a doubt better, but it's rarely the pragmatic choice.

Well, I did mill the PTFE yaws for stickvise myself, and was seriously contemplating building a stickvise style vise (as I pretty much have the needed tools)- until I needed some Digikey part ASAP and had to fill the cart to free shipping t

Thanks for mentioning Omnifixo- when you said it's not cheap, I mentally prepared myself for a price tag of several hundred EUR. I find the ~60EUR price very reasonable (IIRC a single stickvise with PTFE jaws is around the same price p

My understanding is that Galden vapor is dense, so you get a layer of hot vapor near the fluid, with lower temperature further from fluid (where there is less vapor)- the required thermal profile is maintained by controlling position of the

From what I gathered- just dislike, mixed with some concerns. I didn't smell anything apart from the usual flux smell, but I have very little sense of smell.

There are relatively affordable vapor phase ovens- at $WORK I arranged the purchase of Vapor Phase One- it works really well. However, some people are more sensitive to the resulting smell.

Perhaps the particular T962a was just a bad product, but at $WORK we just could not get it working reliably across many types of PCBs- it really required tuning the profile to each type of PCB (small, large, black solder mask vs green, etc)

Many brushless motors (fans, electric scooters) have digital output (i.e. on/off) hall sensors triggered by motor magnets to read a coarse motor's shaft (to know which coil should be energized). There is even a higher resolution a

There is another type of switch even more common in industrial automation: inductive switch, where the trigger mechanism relies on inductive coupling between an external target and a coil in sensor (for all practical purposes the target is

In my country, there is a branch of police that deals with such things. They have a relationship with an organization called Business Software Alliance, which I believe is formed with this specific goal- to allow foreign companies or their

I have noticed pip warnings in the container build logs about python2 being unsupported- perhaps there is some "treat warnings as errors" flag set in some builds. Perhaps some builds use untagged base OS containers- building those

Backwards or forwards depends only on the perspective of the observer :)

It looks like Windows is heading towards Linux in this matter- having to know weird commands to get things done effectively. I only use Windows occasionally, but when I have to set up a printer (shared from another computer) or file sharing

Yes, that probably depends on the relative availabilty/demand in your location. I personally __probably__ would have earned a bit more overall if I had done web stuff, but at least in Eastern Europe, experienced embedded people can get

As much as I hate the word: networking and saying yes when you're in the right time and right place. You probably won't convince a professional widget manufacturer that you're __the__ person for their embedded needs. But a sm

Well, I don't think there is an easy way- I just walked away from the startup and lived on ramen for a couple of years, doing odd-ball contracts just to afford rent. During that time I learned a lot, essentially by telling prospective

Well, since ESP32 is available as chip, you can design a product which is just as robust, safe, resistant to ambient temperature effects, manufacturable at scale as you could with any other TI/ST alternative. With Raspberry Pi, up unti

While I do agree with you, I haven't found the lack of depth in register-level documentation too limiting. On the other hand, I find esp-idf much easier to use than STM32 HAL library and a lot easier to integrate in projects (I do lik

Well, at least with Raspberry Pi, if there is a particular hardware feature, there is at least support for it from Raspbian/RPi foundation. With many SBCs you're on your own if you need something besides "kernel boots, video

Field comparisons of antennas is tricky to do correctly- you really want to use the same location, ideally far away from human settlements (who knows how much background noise was there on a particular test day) and ideally under the same w

Cypress FX2 USB interface chip (usb 2.0 high speed) actually has an embedded 8051 core in it. They did finally upgrade it (to arm9, sigh) for their USB3 variant of the chip.

One additional data point: on my heat pump the economy setting for hot water production starts heating once water cools to ~42C (truly, a universal answer) and heats it up to ~55C. As for anti-legionella, once a week there's a cycle w

Sketcy option. $WORK was desperate for some STM32F42x parts and bought a few hundred from shady distributors (at ~20x the price)- the parts did arrive, their markings made sense, and they did even sort-of work (that is- the debug interface
