Yes. Sorry for not expanding it. I edited it to expand it. For others: The NOHD is really a nominal distance. It's just the distance at which the beam falls below the maximum permissible exposure. The 50% eye hazard distance (ED50) is

They are coming down in price very quickly. The materials cost is really not very high (no idea on the laser itself, but the rest is easily <1k. Probably <500.). The R&D cost was probably very high to start (but also coming down).

So, to clarify - what i have is a very nice IPG lightweld 1500 XR. They are normally not cheap (30k), and are very nice and well thought out safety wise. One of the fun parts when i lived in the bay area was that as companies got acquired

So I laser weld, and beyond my own PPE, interlocks (gun won't fire if it's not touching metal, etc), the most important part of the whole setup is laser safety curtains. Because it's a 2500 watt laser, if i didn't have l

" Infineon's quality department should have immediately reached out to NASA (or more specifically NASA's contractor working on the electronics)." Is there any actual evidence they didn't reach out to every single bu

I'll assume everything you say is right :) The question here is whether Infineon had a contract with NASA or otherwise should have known these were sold to NASA. Again there is nothing cited in the article that says "yes". If

Distributors will notify you of recalls, but no distributor of electronics i've worked with notifies you of erratum (and it would be really annoying if they did, honestly :P)

Right. Like for all the issues here, it's still better to find this out now.

There are actually many - almost every serious (IE 100k+) wood router is ethercat. Centroid (known for the Acorn board) released Hickory, which does ethercat servo drives but not full ethercat support. It runs the same CNC software as Acor

I agree on both counts. You can easily get locked in. For anyone else who is just sort of lurking (you already know what i'll say). Codesys is basically the standard here, and the way to "avoid" lock in - it has the most hard

Most manufacturers seem to have abandoned trying to support them, their community has slowly disappeared, and you can see it. They seem to only care about Espressif these days. Zephyr support has not been updated in ages (2021) Patches subm

I have tried ESP32 a bunch, ESP-IDF itself less. I mainly used ESP32 through platformio (which used the arduino compatibility layer of ESP-IDF), and then through the rust support. I did use ESP-IDF directly for one project, but only for a s

I dunno, maybe i got lucky. It takes me maybe 10 minutes to get clion + zephyr started and working for a new project. If there is board work, at that point i'm playing with making the board work. I started with platformio's zephyr

Prototyping boards - I can totally believe trying to do firmware on a shipping product with real constraints in zephyr would be a pain in the ass because you don't have enough control. I often use C++ with zephyr, which also pretty muc

This author seems like they are expecting an RTOS to be the same as Arduino environment, or at least, susceptible to just hacking around and hoping it works. Most are not. Given a lot of Arduino these days have mbed or freertos under the c

In the case of Argon, it's both inert and non-toxic. The main danger is that it's heavier than air (so you can asphyxiate yourself if you try). As such, "food" grade argon is actually less pure than industrial argon - f

So Ultra high purity stamped argon (99.9999) is twice the price of industrial argon used for welding. Food grade Argon is actually half the price of industrial argon. See https://www.airgas.com/product/Gases/Argo
