Hi @Roshan Baig Mogal Great, these days in Engineering Hour covers wide topics like FreeRTOS, CMSIS-RTOS, etc. with STM32F4 Nucleo. Also, for beginners getting-started type videos incl. basic, adc, pwm, uart etc. I suggest to check the playlist https://www.youtube.com/watch?v=NnwE9EfFpls. Cheers!

Hey guys, what do you think? Is the use of Proprietary software better than Open-source software in Critical systems such as those used in healthcare, aviation, or government? I'd like to know your judgments when it comes to critical systems. Let me hear your view.

ZacckOsiemo•10/11/24, 2:27 PM

If it's a critical software some part of it will surely end up being proprietary and depending on how you develop some parts of it will be open source, I think this is a very wide net cast here. Keen to see what others feel

Ming•10/11/24, 2:33 PM

Define 'better'!
Do you any kind of networking? If so, they are probably using something from the BSD TCP/IP Stack - which is open source.
Do these services run on a server? If so they will probably be running Linux - which is open source.

Having worked in all of those sectors, what you may find is that they want a 'supported' version of things. That's why they want something like RedHat or Ubuntu. These are still open-source

they just come with a support contract and a phone number that the customer can use to shout at some poor techie when something goes wrong.

aying for something != closed source

Accur4te•10/12/24, 3:56 PM

Hey everyone, I'm currently working on an electromagnetic flow meter project and have finished the assembly, including the electrodes and Faraday cage. Now, I’m moving on to the circuitry, but I’m facing some challenges. The signals from the electrodes are in the mV range (or smaller), so I’ll need an amplifier circuit for proper signal processing. Additionally, I’m looking for a suitable H-bridge or similar setup for controlling the electromagnets.

As a second-year undergraduate student, I don’t have enough experience to confidently move forward with the design. Could anyone recommend resources or guidance on how to approach the circuit design for these requirements?

wafa_ath•10/12/24, 5:57 PM

Elon Musk has officially announced the launch of Tesla’s Optimus robot, designed to handle many of the same tasks we saw in the movie .

The price for one unit is around $20,000, which many consider to be quite affordable for American households and even internationally

What are your thoughts on its impact on automation, and would you get one?

Tte0 anyone here who's been working in the industry for years?

Ming•10/13/24, 1:07 PM

Does 30 years in the industry count?
The only thing one can say with certainty is: Smaller, Faster, Cheaper
There will always be a split between Bare Metal, RTOS & Linux - mainly because these fill difference niches. There will just be more of all three.

My only guess is that the AI bubble will burst. At the moment, you just slap an 'AI' label on it and then go raise some investment. This is something I have seen too many times with DotCom, Web2.0, etc, etc.
They all burst - leaving the things that actually had purpose space to grow properly.

LLMs are good for helping, but they don't understand.
There is a lot of good AI/ML out there, but is in far more specific areas not general level intelligence.
When I was researching AI in 1992, full AI was always '20 years away'. 30 years later, it is still '20 years away'! Saying that, the advances are coming through far more rapidly now.
As embedded gets more powerful, then yes, there will be a lot more 'AI' at the edge as there has always been a flow of technology down to the smaller devices. I remember when having a network stack on a hand-held device was exciting!

techielew•10/13/24, 2:15 PM

I’m curious how much the Musk Optimus robots “understand” at this point. You’d think they would have to at least to some extent to perform as advertised.

Tte0 i just wanted to know where is embedded heading to?

Umesh Lokhande•10/13/24, 2:35 PM

These days I see embedded devices in two forms, low-power battery operated devices used widely in IoT. And other category is power-hungry devices, capable of running n training AI algo. and require huge compute. Now as future is AI, with embedded devices surely become more expensive in terms of power consumption. Because energy is not yet cheap at many geo. But, I agree and enjoy reading news and learning associated cost in the market for operation and deployment. By the way it's possible to run small logic (pre-trained model) in the form of rules to perform at the edge for battery-operated embedded devices. Now you can called it as AI or not is very subjective. Happy to hear from others perspective.
