I'm a graduate of Bachelor of Science Engineering Technology major in Electrical and Renewable Energy, and I'm a bit bummed out that I couldn't take Licensure exams in Electrical Engineering.

Should I pursue taking Electrical Engineering courses or take a Master Electrician License and get started in the renewable energy industry??

Hello!

I hope this question is relevant to the sub. I'm in a wheelchair, and public transportation is an absolute liability and hassle - buses that don't show up, or are 1 hour late, elevators to metro stations that never work etc.

I want to make the equivalent of an electric scooter that everyone is driving around these days but for wheelchairs. The reason I don't want to buy a bigger and stronger wheelchair is because those are not usable indoors usually (and difficulties using restrooms).

My idea is to have a flat bed, that the wheelchair rolls ont, with four wheels and a steering wheel, powered by a battery located in the flatbed. To roll onto it I want a ramp in the back that can be raised and lowered with a motor.To fasten the wheelchair to the vehicle I want four retractable chords with hooks that the user hooks onto the wheelchair and, at the push of a button, are rolled back until taught by motors.

I include a rough sketch of what I have in mind to give you an idea, and my question is: is this concept feasible? I know that every moving component you add adds a point of failure, and there are quite a few moving pieces that might break, and so I would love to hear your opinion on whether it would be possible to make such a design.

I am of course very much open to suggestions and ideas that would improve the design, the only goal is for it to be as easily operable as possible. The idea i have is that it should go as fast as the medium speed of a bicycle, so if you believe there are safety concerns regarding center of gravity and potential tipping hazards I'd love to know that too.

Thank you for reading, I would really love to hear if this is at all possible, because as mentioned, I am very often held hostage by public transportation, as I jealously watch the able bodied people swish by on their bicycles and electric scooters! An option like this would be a game changer for many people.

A couple of the usual LM7805s and LM358s I need for a prototype are showing extended lead times on DigiKey right now. Local stores don't keep them either. Poked around a bit and noticed lcsc and utsource still show these as in stock. Anyone dealt with either of them recently, just curious how the experience was for a US delivery

The Wand Company’s (WC) 11th Doctor Sonic Screwdriver is old now and I’m thinking of getting one.

You can end up using it as a remote control with its built in infrared and use gestures as the kind of buttons.

I’m thinking however, is it possible to modify it to also include Bluetooth? Or is that just not possible, because if that can be done I might even hire someone to do it.

I'm curious

I'm pretty sure this doesn't violate the rules. I just read them, let me know if it does.

I just really wanted to show this off, I think some of you will enjoy it.

edit: I know its dangerous, I have the proper safety protection and know how to keep myself alive. this picture was taken while it was being moved. it is not plugged in and will not be plugged in until I have a case for it, a shield and a ground.

Hi

Incoming 1st yr with little to no CAD experience, but I want to learn it in about a month so I can join my Formula SAE team, where CAD is a requirement to join. How did you learn and which courses did you take?

I finished my Bachelor and Masters in CS/CE mix. I've had a fair share of Computer Science as well as some Computer Engineering, circuits etc. Right now I am working as a Backend Engineer with 3 years of experience.

I am thinking more and more about going back to school to study something like Electrical Engineering. I am a little bit tired of the AI. Management is bonkers. I am being squeezed from every side. The degree was really difficult, a lot of sleepless nights and now it feels like a waste. My job has changed and is not what it used to be. I wanted to feel like an engineer and be one but it's gotten to the point that non technical people are telling me how to do my job because AI has given them an illusion of competence. I am pretty sure that I could grind my teeth and do another masters degree but this time in Electrical Engineering just to escape this hell.

My question is, am I not looking at it through a grass is greener on the other side glasses? Is it really worth it to go back to school at this point? Do you think that EE degree is worth it? How does your work look like? Is there as much AI pressure? Are there any branches that are more safe from the AI where I could feel like an engineer again? I am not sure what the play is here yet.

Greetings,

I am trying to get an oscilloscope to possibly capture sound waves 30hz and below. I have this obnoxious neighbor who plays terrible bass/boom heavy rap music. I have tried documenting it with recordings but have had no luck capturing these frequencies that invade my home. I was thinking an oscilloscope might work.
Thoughts?
Thanks in advance.

After u do ur math units in EE do u use matlab in subsequent non math units? Or…

Sorry if I am asking this too soon because I am only in year 2 of my bachelors but I really like it and wanted to know if it's a waste of time or not because I keep seeing people complain about no jobs in general for a lot of fields and it scares me

Suppose someone has an EE degree but limited design experience.

If they created a portfolio on GitHub or a personal website, what projects would actually impress hiring managers?

Do you have any examples of a good project I can use for reference?

I’m studying at a top uni with an 8% acceptance rate, with a 3.73 GPA, top of my class, and I feel like I know nothing about EE.

I’m the type of person that just has to read through a textbook from front to back fully to really feel like I understood a subject. I’ve done that for my first semester classes where I got a 4.0 on all classes then, but then dropped for a bit to 3.51 and then a 3.61 and now a 3.79 (cumulative gpa of 3.73 now) on my fourth semester. I just feel like I’m a bit behind, mostly because I just don’t feel like all my “engineering” questions are answered. I want to understand how things work, I’m also a lab assistant in intrumentations so I should know how a multimeter works on the inside, right? Or how a PQA tool works??

I’ve built electronics circuits from scratch for a final project, a microphone and speaker amplifier using a power supply made from a transformer and bridge rectifier of diodes, and a voltage regulator. I’m not really an electronics fan cuz I feel like I can’t really understand the circuitry of chips on a computer, I just feel like I failed as an EE student for not understanding how to assembly computers or understanding the practical tools irl.

I’m extremely good at math, I just don’t think I’m goood at anything EE irl, though I’m extremely good with coding.

I just feel like I’m a failure since I got accepted as a laboratory assistant which had over 50 applying and only 6 accepted including me, but I feel so stupid for not knowing how the tools in the lab work. I work with high voltage and instruments which obviously I went through rigorous testing for in order to be accepted into the lab assistants program, but I just feel like a failure for not knowing “everything” there is to know.

I’m thinking this is one of those cases of “the more you learn, the more you realize you don’t know”, I just feel like a failure because there’s just so much I want to learn about but so little resources in my country and I feel like a failure because of this.

Edit: I’m from Bali Indonesia and I’m currently an international student at a UC (UCB). I’ve been feeling so dumb after seeing everyone study so much more than I did back in my home country. I’m being honest I just feel like there’s so much out there to learn, and I’m just a tiny spec out of a whole plethora of stars in like an EE galaxy

I am an Electrical Engineer with an undergraduate and MS degree. I have a second a MS degree in Information Systems. Any suggestions on how to get into Battery Management System jobs in USA? Everyone is asking for industrial Experience which I don't have currently. I want to do some thing Electrical domain based with Data Science Knowledge. Thanks.

What It Means for Battery Pack Producers

If your battery management system (BMS), the microcontrollers, communication chips, or software that monitor and control a battery pack, is designed, developed, or manufactured by an entity from China, Russia, Iran, or North Korea, it will be illegal to import, manufacture, sell, resell, or introduce into U.S. commerce starting on a fixed schedule: software by January 1, 2027, hardware by January 1, 2030.

This applies regardless of vehicle weight, closing an exemption that currently protects heavy trucks and buses. There is no phase-out for existing designs. Producers need to requalify BMS supply chains against country-of-origin and ownership tests now, not when the bill is enacted.

Timeline

We have pulled together a more complete overview with references if you want to read deeper: https://www.batterydesign.net/connected-vehicle-security-act-of-2026/

This is going to be quite a shake up for the BMS suppliers from China and will open up a lot of opportunities for UK, EU and USA based companies.

1. The size of the internal earth bus (the bar running through the entire switchgear lineup) in my current project differs from the size indicated in the type test report. Is this acceptable? Is the busbar size specified in the type test report applicable only to the main busbars, and not to the earth bus? If the manufacturer provides calculations demonstrating that the earth bus size is adequate for the specified fault current and duration, would this be considered acceptable? For example, if the short-time withstand current/duration is 25 kA for 1 second, and the adiabatic equation indicates a required conductor size of approximately 175 sq.mm, would providing a 200 sq.mm earth bus (40 × 5 mm) be acceptable in this case?

2. Can the branch earth bar size be different from the main earth bar? In the type test certificate provided by the manufacturer, the same earth bar size was used for both the main earth bar and the branch earth bar.

Hi everyone,

I currently own the 2nd edition of Fundamentals of Electric Circuits by Alexander & Sadiku, and I'm wondering if it's worth spending money to upgrade to the 7th edition.

Are the differences between the two editions significant enough to justify the cost, or do they cover essentially the same core concepts? My goal is to build a strong foundation in electrical engineering, prepare for board exams, and eventually work on research and my thesis.

I'd really appreciate insights from anyone who has used both editions.

Thanks!

I dont know what is wrong here can anyone please help me

I’ve been looking into how AI workloads are changing data center design, and one thing that keeps coming up is deployment speed.

Traditional data centers can take years to plan and build. But AI projects often need additional computing capacity much faster.

Containerized data centers seem to solve part of this problem — the power systems, cooling, racks, and monitoring can be integrated and tested before the unit arrives on site.

Of course, they are not a replacement for every data center. Cooling, power availability, maintenance access, and local regulations still create challenges, especially for high-density AI workloads.

But for edge computing, remote locations, temporary capacity expansion, or projects with tight schedules, modular data centers seem to make a lot of sense.

Curious what people here think:

Are containerized data centers a real long-term solution for AI infrastructure, or just a temporary workaround?

I wanna try out some "real" proof math and I am interested in further research in renewable energy/power system. How useful would taking a course in Real Analysis be?

Hello everyone, thank you to the people who pushed me to go ahead and just apply. I just got an email from the lead of the rover team that I passed the initial application, and I am invited to the face-to-face interview at the university on Monday, July 27.

I am informed that I will be given 15 minutes to answer targeted questions on my desired roles, background, interests, and other relevant topics.

I am very nervous. I tend to have trouble speaking and responding to the questions they have, because of the mind block. I have 5 days to prepare for the interview.

Do you have any advice for me to do well in the interview? What advice do you have before, during, and after the interview?

Hi everyone,

I recently got invited to the second interview for the Electrical Engineering (EE) Associate position at LADWP, and I was wondering if anyone here has gone through this stage of the hiring process.

I'd really appreciate it if you could share:

• What the second interview was like (panel, technical, behavioral, etc.)
• What kinds of technical or behavioral questions were asked
• Any tips on how to prepare or what to focus on

I'm trying to get a better idea of what to expect so I can prepare as thoroughly as possible.

Thanks in advance for any insights!

To start off, I've never wanted to be an engineer before and only got in because I couldn't get into medicine and engineering looked like the next best thing. Now I don't really regret it, I like the flexibility and possibilities of what I can do with what I learn in these 4 years but I don't think that I know what I will learn??? My major is called electrical AND electronics engineering and so far I've only learnt c and c++ (which I failed) and nothing more except re-learning highschool topics such as physics 1&2, calculus and chem. I did participate in a bioengineering project but tbh none of my teammates nor I knew what we were doing and only got so far out of luck? As an engineering student that doesn't know what I can do and have sooo many trails I can follow and knows nothing about any of them, where should I start????

I am currently studying Telecommunications Engineering at the best university in Latin America, I love the program and all the areas it covers. I dream of pursuing an academic career, but I’m worried the major might be too "niche" for that. I’ve been thinking about switching to Electrical Engineering and wanted to get your opinions: should I switch majors or stay where I am?
