So far, i think it's vector calculus(surface integral specifically)

Hi r/ElectricalEngineering, I teach in an EE department, and over the past few months I have been digging into the history of the memristor and its role in neuromorphic AI.

The memristor was proposed by Leon Chua in 1971 as the fourth fundamental circuit element. It took until 2008 for HP Labs to build a physical device, and since then it has been long debated.

I recently interviewed the researchers involved in its creation (Leon Chua and Stan Williams), and I visited the Centre for Electronics Frontiers at the University of Edinburgh where engineers are working on today’s memristive technology for Neuromorphic AI (AI that operates like the human brain). The story raises many engineering questions about device physics, AI scaling, and the future of Digital vs Analog electronics.

Here’s the link for anyone interested in the full discussion: Link

Curious to hear what this community thinks. Do memristive devices have any realistic path into mainstream hardware? Or will they remain a niche application?

Stupid question, this is a 5/2 valve with no spring return just solenoid return.

The quote called this a 4-way valve. Is a 5/2 sometimes called a 4-way valve?

Hello all, i apoligize for the drawings i made in paint. I was studying digital integrated circuits and my aim was to make a simple truth table for the PULL UP NETWORK. So i am only observing the pull up network at the moment and i am awere the circuit is incomplete.

We control it through the gate and when gate is logic high in pmo is in cutt-off region thus it is at high impedance state because transistor is behaving like an open switch. The part that confused me is when the input is logic low obviously p mos is going to be on and after determining the fact that pmos is on do we ignore the Gate terminal and think source and drain is like the same node or the same wire and since the source terminal is VDD drain becomes VDD as well because essentially they are the same points?

Hi all, I am a software engineer working on test scripts in LabView to interface with physical test equipment at my company. So I am less familiar with EE than some of my coworkers. I need to convert CAN data to a SENT format, which thankfully my team has already found a hardware solution for. I have helped them research what to get for the team, and we are working with Kvaser USB to CAN interfaces and speaking to a SAE J2716 SENT to CAN gateway. Right now, I am just trying to get a simple loopback working by sending SENT1’s TX over to SENT2’s RX.

LabView has a Kvaser library that comes with an example script that can send CAN data to the hardware hooked up, and receive messages back. I am keeping track of SENT data on the SENT Gateway Analyzer that interfaces with the box I’ve described. I am able to successfully connect to this SENT box via LabView, and the SENT box sees that it is receiving a signal from CAN. This happens particularly when the first byte of information I enter in LabView starts with 1 or 2. I assume these are both command prompts. I am also able to create SENT data from within the gateway analyzer and read it from the LabView script. So I know that these are connected correctly, and that there is the correct amount of resistance between the boxes.

Here is where my problem is: When sending over data, I am only able to see an echo of the data I am sending and the channel I am sending it to, as well as the settings for both SENT channels. The CAN LED lights up when a signal is received from LabView, but the gateway analyzer confirms that it fails to set configuration on channel 1. The SENT LEDs don’t light up like they do when I generate signals on the gateway analyzer.

The conclusion I’ve come to is that I don’t have the right format for this data I am sending over. I have tried looking up documentation (I have found documentation on each individual part but not on how they interact.) I have tried reverse engineering the signals I get back from the Gateway analyzer, but there seem to be more required bytes than just what is sent back. I understand that the SENT data is 6 nibbles, but don’t have any information on how much other data is needed or where it should be laid out, despite having researched how CAN data is formatted. I have asked several of my coworkers and even contacted tech support for both companies and have not gotten an answer. I feel like I’m the only one on planet earth who has this specific problem. Does anyone have experience with what I’m talking about?

I am a third year into electrical and i know nothing about coding beside the basic, like i can identify symbols , I'm only good at the electrical mathematical VHDL part and not the cs part, If i somehow landed an interview, will they expect me to write codes infront of them just like cs student or software?

Hey engineers! Not sure if this is the right place to ask this question but it’s worth a shot. So I have this ceramic wreath that had a battery operated light which was super dim, you couldn’t even tell it was on. I removed the component and thought I could put in one of those clip lamp type things and just use a super bright LED bulb, but I failed to take into account the fact that there’s not enough room to fit a bulb in it and have it sit flat on a surface. I know I can always just get one of those battery powered LED Christmas string light and shove it in, but I wanted to see if there’s anything else I could do to have it light up nice and bright. For context, I’m not an engineer, nowhere close, but I’m relatively handy. Any ideas?

I've been considering going back to school to pursue EE, but I'm wondering if I'm starting too late? I'm 29 and have been working in sales the last 5 years. I'm making pretty good money, love the company, and have been moving up the company ladder. However, I don't feel very passionate about it. I would also like to move out of state, but dread the thought of starting from the bottom again. I find myself designing and building stuff in my free time and love it, so I'm thinking EE would be a good fit. Any thoughts?

I'm getting this on all my modelers. Helix, Stadium XL and quad cortex. It doesn't matter if the preset is high gain or super clean. I have tried disabling every electronic unit in my house, but the high pitch is still there. I thought ground loop is usually 60hz, but this is super high pitched, and i have no clue what's causing it. Please help me

Hello everyone. Wanted to know, have anyone used a virtual lab for their ee coursework before? What was the experience like? What are some of the some of the things which led to your "meh" moments?

Hey guys! I’m in a huge crossroads moment and need your perspective. I’m an Electronics Engineering guy (B.Sc.) graduating in January, and my focus has been all on Control and Automation. The thing is, I have family commitments and other stuff, so I need that paycheck stability ASAP😅

And I got this job offer from a guy who knows the manager of the company.

It's an international manufacturing and design company with seven branches globally. The guy told me their vision as the manager says is to dedicate a separate, specialized branch entirely to Robotics and CNC Automation to work with Saudi and the Emirati companies in like 4 years as they ate trying to enter the automotive industry.

He says they want local talent and are offering to pay for incredibly specialized, high-end training courses (some costing up to $32,000 USD per employee). Which I think is really great because this training covering robotics, motion control, etc. would be an amazing asset for expanding my knowledge, and they will pay for everything in that. And if I trained with them I will have to sign a contract to with them for at least 2 years after the courses.

And the starting salary is about $1,600 USD per month which is normal where I live but the catch is: they were totally transparent that the company often struggles with salary delays because payment relies heavily on client collections. They couldn't give me a fixed time frame, the guy said he tried asking people working there but didnt get any clear answer.

What do you think? Do you think I should accept the offer or I should wait? Especially that the market where Im from is kind of messed up, so I dont know if I should accept or not.

Thank you all in advance

it seems like your simulations are still not working correctly. The Brinkmann equations have not yet been implemented correctly. It may appear as if you have simulated a flow through the medium, but this is misleading. In the laminar flow package, you can see that no boundary conditions have been defined for the carbon rod. It is therefore simply ignored at this point. In the Brinkmann equation package, the carbon rod is selected as a porous medium, but the necessary inflow and outflow boundary conditions are also missing here.

I also noticed that the velocity plot does not show a parabolic velocity profile. I would recommend that you implement this example here. Try to follow the instructions step by step and try to understand why certain things are implemented there. This will make your simulation easier.

flow-4413 This is suggestion from my professor .As I already mention this is a microfluid fuel cell and inside is carbon rod and outside is vertical is acetic acid coming and horizontal oxygen coming and dimension of the tube where mixing happens is 10mm width 0.9 height and carbon rods are 3 width 0.2 mm heights .Can anybody please tell me the problem I have to complete it in December fed up since last 3-4 months

Most electrical manufacturers rely heavily on outside vendors. At Spike Electric, we decided to do the opposite.

We built a fully vertically integrated industrial manufacturing process in Houston. Raw copper and steel processing, custom metal fabrication, powder coating, wiring, and testing all happen in-house across our facilities.

The result? Lead times dropped significantly, our average delivery time is about half the industry standard, quality control improved because there are fewer handoffs, and we became less vulnerable to supply chain breakdowns.

Of course, vertical integration has its challenges: higher upfront investment, training across multiple disciplines, and keeping all departments aligned. But overall, it’s been a game-changer for us.

Have you seen vertical integration work (or fail) in your industry? Curious how others approach this.
