Pelican is a manufacturer of rugged cases, often used to transport expensive/fragile equipment.

Pretty much every security camera, most of the networking equipment, action cameras and set-top boxes run Linux from NOR flash (cost and simplicity reasons- no FTL, IIRC better retention). Altogether it's probably billions of devices.

For NAND flash, maybe the difference is miniscule. For NOR flash, which is what many small embedded devices run from, the difference is huge: 128Mbit (16MiB): 1.01$ 2Gbit (256MiB): 16.38$ 2Gbit is the highest commercially available packag

Easier said than done. As of few years ago, Qualcomm wouldn'y really talk to you unless you can guarantee at least 100k unit purchase- which gets quite expensive fast at ~30-40$/pc for a mid range SoC. At the point where we got ac

UL started that way: insurers grew tired of exploding steam boilers and asked their owners to have their boilers inspected and only insured owners who adhered to safety rules. I'd imagine insurance companies would hold the providers to

Also, RSSI is typically calculated from the successfully received frames. So you can receive a comfortable -60dBm signal.. for the most of the time.

Lightning crosses several hundred meters of air at the very minimum- what makes you think it won't arc over a few millimeters more, if that's the path of least impedance? In general even the most rugged lightning/surge protec

Judging from the rest of engineering disciplines, people figured out the right process that yields reliable results- we don't have too many civil engineering failures, exploding steam boilers or houses burning down because of overheati

Second that. Before arch, my desktop linux experience ended with me breaking the system and not having a clue on recovery (a few attempts at slackware and one attempt of debian). Arch's install process hit the right balance of me knowi

Not that STM32 is any different. Recently I designed around STM32F105 specifically due to it's ROM USB bootloader. Too bad I didn't read the errata which says no USB bootloader for 64 pin package.

My anecdata in ~ 50,000km riding time on a motorcycle: a frontal crash I could do nothing about (oncoming car made a left turn, didn't see me). Luckily it happened in a city and I was in full leather tracksuit. I got through with a few

This is probably the first time I am excited to hear about "X in webassembly". While it'll likely be a lot slower than native implementation, the benefits of an image not leaving your computer could unearth some interesting a

How's the situation with python packages that have native code parts? Previously they had to be compiled during installation, which wasn't easy on Windows.

I've heard that their executives/PMs are top notch, so 5-10k month net might be on the high side, but not outrageous IMO (assuming the Estonian job market is a bit more expensive than Latvian, which I'm familiar with).

Interesting, as I surely thought they will be one of the companies benefiting the lockdown.

Or have some drinks with EEs and get them to value software development ease of use: things like using top of the line, or at least midrange MCU with enough flash for debug builds, populating debug connectors on EVT builds etc

Depends on your frame of reference. Industrial programmable logic controller (PLC) programming environments I've worked with also use "upload" for uploading program from PLC to PC and "download" from PC to PLC. Migh

There's actually even more than this to low price. I have seen knock-off ST-Link dongles with STM32F103C8 MCUs that are not supposed to have enough flash memory for the stlink firmware, yet they functioned. How? Turns out they physical

Professionally- agreed. However I look at it as a learning exercise, which is a wonderful way of calibrating one's sense of time/money quadrants. If you don't have time, but have money- send it to overnight PCB service. If

Another way to step up the resolution a notch is using photoresist coated PCB and a small UV laser. It is typically a negative process (exposed photoresist dissolves in developer solution), so you'd have to invert your plot/gcode,

The way to get Amazon to fix this (at least on this particular item) is just that- publish an article that you get granola (which I assume costs more) for the price of empty boxes. Nature (i.e. the internet) will fix the problem for you by

I think of it as WiFi Alliance. You would expect several WiFi devices connect to the same AP, but you probably wouldn't expect a random widget from company A to interoperate with random widget from company B.

Increasing a single cell battery system over 10Ah is not trivial. First, the RK3399 and it's companion PMIC is designed with single cell applications primarily. Second, I don't know the exact reason why, but commonly available lit

Do check the new ones- when I ordered it for my current work I had to return two of them in a row- space bar had only one button/side working. I'm still using the one I bought ~10 years ago at home though.
