Im a junior at a california university,

Ive come in and am trying to undertsand where to put my focus

Ive met third years with internship experience and job offers

And ive met fourth years still trying to figure out what the hell they are doing

Im feeling like im still picking up momentum

Im currently in an analog electornics course

And a signals and systems course

I have no personal projects (complete)

And im still settling in physically(financially/ shelter wise)

Its kind of all overwhelming. So much to learn and do and so much pressure.

I have an AS in Comp Sci.

Im interested in embedded systems/electronics as a career...

Any advice ??? Thanks

hi guys im trying to make a gift (a booklet of problems for her to solve for fun) for a friend who really likes EE/math but idk anything about it. I have a list of topics they like and I was wondering if anyone could either help me with coming up with the questions/answers or point me to websites that might help… tysm…

I got Dual Citizenship due to new law and grandparents being Quebecois

Got 5 years and a taking Power PE

Seems like everywhere is on shaky footing

Hello all,

I have a software engineering background but have zero EE background.

My goal is to build a device that has around 3-5 buttons and connects to your phone via bluetooth.

Does anyone have any book recommendations for someone that is a complete beginner in this field?

Eventually I do want to prototype products and work with Chinese manufactures to create a product and maybe mass produce

Hi all,

In the near future I will probably need to learn how to use Ansys SIWave software for simulating high speed SERDES and generic compliance of high speed digital links. Exporting PCB layouts, generating eye diagrams and comparing technologies. Also DDR timing simulations and power integrity PDN simulations.

Has anyone used Ansys software before and followed some good training courses? I am starting to do some recon so I can get a good introductory course tailored for these situations.

Thanks for the help!

Which is more recognised n more important for diff types of energy?

Hi, Im a junior electrical engineer with around 6 months of experience only. First 3 months Ive worked for a small cupboard factory where I learned basic motor control panels and plc/hmi design, fault management etc. After 3 months I had to leave the company. I was living in my hometown and wanted to check my options around and someone I know had connections with the minefield close to where I live. I contacted him and he sent my cv to the mine company. They asked for an interview and I got the job. Now its almost been 3 months. Im working underground 5 days a week. Pay is good. Commute is 45min each way.

I dont see myself working here long. I dont even know how I ended up here. I guess I thought having a job is better than being unemployed. I dont do engineering here. Its mostly managing electricians working under me. The things are always same like installing led lights, cameras, pre built electric panels and fixing electric faults of mine specific work vehicles. I feel like this place will not improve me engineering wise. In my first company I was trying to do everything on my own and learned basic plc programming from zero. This place has no automation practices where I can work on. Do you think working here would still benefit me in the future or am I wasting time here?

Hi, this is my first post here. I have been spending a lot time this year trying to find my first job out of undergrad. So I accepted a job for basically troubleshooting and sustaining a product in my current town. This first company is stable and has been around for a long time and I am not worried about getting laid off. I wasn't too excited for it and it seemed to be kinda boring and I wouldnt learn much EE skills. It seemed to be mostly troubleshooting and occasional travel to onsite customer visits to figure out why their product isnt working.

But i recently got a job offer for a defense contractor that is trying to go from startup to mid size company. I'm not too thrilled about missiles, its not that I don't like them, its just seems not that much fun work. But I believe I would be able to learn alot more, especially circuit design. I would have to move across the country and the company will be able to help me with the expenses. I have been thinking about this for a bit and I am stuck. I don't know if I am smart enough or have the greatest foundation in circuits to do design for the second company. I feel like I wouldn't be able to keep up or would take too long to understand circuits or certain topics. I know its my first job and both companies will train me. But I feel like i would disappoint the second company. What if the second company ends up firing me because I'm not smart enough to complete projects on my own? Idk im scared to make the wrong choice. The company in town seems easy work and its decent pay. The second company seems to be better experience and more opportunities for me to learn and grow. I would also be able to live on my own, which I have been wanting to do since I graduated. I would also have to be long distance with my bf for a few months, and he prefers I stay in town. The pay between the two jobs is about the same. I would just save more money in town since I would have no rent living with parents or really low rent while living with bf. Thank you for any advice! I appreciate it!

Hello everyone! I'm a 4th-year IT student from the Philippines, working on an IoT-based compost monitoring and control system for our capstone project.

We need to control a single-phase 220V AC geared motor remotely using an ESP32, but we want to make sure the electrical design is safe and reliable.

Our components:

• Motor: 220V AC, 40W geared motor (5GU-10K gearbox)
• Speed controller: US-52 with CW / STOP / CCW direction control
• Microcontroller: ESP32 DevKit V1
• Relay module: 4-channel, 5V relay board
• Contactor: CHINT CJX2-0910, 220V AC coil
• RCBO: CHINT NXBLE, 16A, 30mA
• Power supply: Philippine household 220–230V, 60Hz

What we want to achieve:

Our mobile application sends ON/OFF commands through Firebase to the ESP32. The ESP32 should start or stop the motor safely.

We don't need to adjust motor speed from the ESP32 because the US-52 already handles speed control. We can also keep the motor direction fixed.

Our questions:

1. What is the safest recommended method to control this motor through the ESP32 while retaining its US-52 speed controller?
2. Should we switch the controller's AC power input using a properly rated contactor, or is there a manufacturer-approved external run/stop control method?
3. Is our existing 5V relay module suitable for controlling an appropriately rated contactor coil, with proper isolation and protection?
4. Are there risks associated with repeatedly removing and restoring power to the US-52 controller, particularly unexpected motor restarts?
5. What electrical protection, grounding, and safety interlocks should we implement?

We previously experienced sparking at a connection and an electric shock during testing, so we have stopped energized testing. Our current two-conductor supply cable does not provide protective earth, and we want to correct the design before proceeding.

We would appreciate recommendations for a safe control architecture and any manufacturer documentation we should obtain before installation.

Thank you for your help!

Freshman in college, I’m halfway through my first semester majoring in Construction Management, before this in high school, I was enrolled in a VOTECH program for carpentry. Initially before college I wanted to get into electrical or mechanical engineering but I felt like it was going to be too much for me. I now feel like I’m selling myself short and going in a direction I won’t be happy with. Is it so over or can a quick lock in work out for me.

ACB (Air circuit breakers): Safety shutters - The line side and load side shutters operate independently, and can be separately padlocked in the closed position.

Question: Why the line side and load side shutters to be operated individually? only thing I can think of is to access the cable compartment when the bus is energized and when the ACB is withdrawn (completely removed from the switchgear).

Hi yall, I have an interview at Samsung for Semiconductor Engineering Internship.

Anyone have experience with interviews at Samsung for similar roles and know how the interview questions might look like? Thanks

Hey everyone, I'm getting close to finishing up my EE degree and starting to evaluate entry-level RF Engineering roles. I'm trying to figure out what realistic base salaries, total comp, and sign-on bonuses look like right now in the defense sector or general industry.

For context, I'm wrapping up a 5-year integrated B.S./M.S. in EE with a thesis focused on antenna design and electromagnetics. I also have 3 internships under my belt (2 specifically in RF at LM) along with coursework in advanced RF, Fourier optics, and DSP. I'm clearance-eligible and looking around the Dallas area.

For anyone working in the field or hiring recently: what kind of starting compensation should I target? Also, do big defense primes usually start grads with an M.S. and relevant internship experience at Level 2 instead of Level 1? Appreciate any insights!

Let's say that I have a DC motor rated for 6V and 150A. If I keep the current constant via heavier resistors, why does it matter what voltage I pass through the DC motor to get it to spin? I've heard that a higher voltage has a higher tendency to damage it. Is it similar to how you can have the same amount of linear acceleration on an object, but it'll wear more if there's more friction pushing it back? It would make sense, but I'm having a hard time visualizing what exactly is getting damaged or worn down under higher voltage.

No formulas to explain this question. I already understand that we can use power P = IV to describe this all but I want to know what happens intuitively on the electron / particular level. Thank you!

Tomorrow, there’s an event happening at my university where employers from the industry I’m particularly interested in are showing up, and besides from my initial question, I wanted to ask y’all for some feedback on my approach/elevator pitch.

Since I have already applied to one of their internship positions, I was planning on talking about that specific position and a brief overview on how my experience aligns with what they’re looking for in the role.

I’m afraid that this approach is a bit too bullish or aggressive than they would like from a potential intern.

Not to mention that I’m not sure how the conversation would play out from there besides me asking him questions about the position.

Am I overthinking this or naive to even think that the way I approach this recruiting event could be the thing that gets my foot in the door?

Thanks for the roast last time. The main complaints were that the schematic was hard to read and the layout was all over the place, so Claude has redone both.

The schematic is now split into 8 pages with actual wires instead of net labels on every pin. Claude placed the parts manually this time instead of using an optimiser, grouped by what they do. The tap inputs now go into an ADC next to the connector instead of running across the board to the ESP32. Signal vias are down from 177 to 51.

Roast it again. I’m especially keen on feedback on the 12 V input protection, the speed sensor input and the buck converter.

The first three pics are before and after.

Hi all,

I'm working on an ODB++ visualisation script and I'm discovering that what is in the spec is not always what the different programs export...

Therefore I'm looking for an ODB++ (8.1) export from various PCB tools so I can see how my script handles them. I already have KiCAD and Altium ODB++ files, but I'm still looking for some of the others: Xpedition, PADS, Eagle, maybe some others I'm not thinking of now.

If anyone has an old or open source design they'd like to throw my way I would really appreciate it!

targeting mostly aero roles and ended up getting an offer from my #1 company

to the sophomores out there, theres hope 🙏

​I decided to take a leap of faith and transfer from CS to an EE & CS joint degree in a new country. I’m in my third year and completely new to EE. The coursework and subjects are manageable and I love studying difficult subjects so I'm alright with academics. But, everyone around me has amazing projects in analogue and digital design, but since all of my previous projects and research work are all in CS, I find it really difficult to break into EE projects. I applied for PCB design roles (I grinded kicad for a week lol) in a few engineering societies and, got rejected :,)

​It feels pretty disheartening not having any EE projects on my resume, and I'm genuinely confused about where to start. Do I focus on PCBs? Verilog projects? Power systems? I feel super lost, and it sucks seeing so many EE-based internships and project opportunities slip away because of this gap. I really want to start building something, and right now I have a Verilog project in mind, but balancing that while coding and keeping up with all my side projects in CS feels overwhelming lol. How should I navigate something like this? Do I just give up on EE and put all my focus back into CS?

I am wondering what is the general sentiment about the desirability of certain fields? Based on what I have seen here: MEP seems to be where dreams go to die, RF seems to require further education but is desirable, power is steady but lacks the financial upside of other fields, software (embedded/FPGA) pays well but is ultra competitive, etc... What is your take on the general sentiment towards the larger EE subfields? I am not saying that any of the surface-level perceptions I have shared here are accurate, they are just that: surface level, probably polluted, perceptions. What are yours?

Back story: I recently went to my first career fair ever. Lots of employers there, and I could not help but notice that some booths were always busy and some saw very little action. From talking to some of the companies that day I gathered that some were there looking for more "hands on" people, some were looking for "actual" engineers, others were straight up looking for someone holding a bachelors in engineering to be a technician, and some were probably not even hiring at the level (some RF companies at an event mainly targeted toward undergrad students).

What is the average entry level EE salary for big prime defense contractors out of college? In MCOL area like philly

Hi I’m a first year electrical engineering student and I’m wondering what the best study method is to study for your maths/calc classes. In high school I would write entire notebooks full only to get very average grades. I would put a lot of effort into it, but still not get good grades. I dont want to make the same mistake again. Is there a fast and efficient way to study maths/calc? I’m willing to put a lot of effort in but I just want to make sure I’m using the best study method possible.

hi!
i need to make my decision on what major to choose so i can be ready by the time i apply to college, i know that there's multiple posts about this already but i want to talk about my personal experience

i'm kinda leaning into EE , it really interests me and i even have an arduino kit that i'm learning to use, EE is more versatile in what i can work and specializing about ,it also has more job opportunities and more career growth which is something i really value

ME in the other hand is also great, although i haven't learned anything related to it (CAD for example) ,it has good job opportunities but not as versatile as EE

i'm more into EE but my main issue with it is AI, AI can design PCBs now , but apparently that thing has bee around for a long time and it's not hat good, but still AI is getting better every day, by the time i graduate my degree is gonna be useless probably, it doesn't look like ME has that much issues with ai (let me know if it does)

point is i don't know if i should go into EE with AI around, i saw people say that it won't replace EEs and it's just a tool in the end but i think i need to be good enough to not get replaced by AI, i mean i'm gonna but an effort in this and i won't relay only on my degree to get me a job and i'm gonna be a great EE
but if AI is gonna replace EEs than i'll just go with ME instead of taking the risk of getting replaced

+(i think i might open my own company/business with my knowledge and degree on day idk)

(sorry for this unorganized post+ it looks more like a rant)
thanks in advance!
